3. PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed:

FIELD OF INVENTION
[1] The present disclosure relates to a medical device. More particularly, the present disclosure relates to an intravascular lithotripsy device.
BACKGROUND OF INVENTION
[2] Intravascular Lithotripsy (IVL) is a medical procedure designed to treat calcified plaque in arteries, often in patients with coronary artery disease. The IVL procedure involves the use of a catheter that delivers sonic waves to break down the hardened calcium deposits in the vessel walls. Once the plaque is fragmented, the vessel can be dilated to restore blood flow and maintain the opening. IVL is particularly useful for effective fragmentation of rigid plaques in the vessel and vessel dilation.
[3] During the IVL procedure, an inflatable balloon catheter is inflated at the site of the calcified plaque. As the sonic waves are delivered to break down the calcium deposits, the blood flow through the affected artery is temporarily reduced or stopped. The blood flow is temporarily reduced or stopped till the time the procedure is being performed, generally lasting only as long as it takes to fragment the plaque and allow for safe dilation. The purpose of reducing blood flow is to prevent any fragmented plaque from dislodging and potentially causing downstream blockages.
[4] While the reduction in blood flow is necessary for the success of IVL, it can lead to specific complications, if not carefully managed. For example, the temporary reduction or stoppage of blood flow during the IVL procedure can result in ischemia. This condition occurs when tissues downstream of the obstruction do not receive enough oxygen and nutrients, potentially leading to tissue dysfunction. While this is usually a short-term effect, it can be problematic if blood flow is not restored promptly.
[5] Further, if the blood flow is excessively reduced or there are delays in restoring it after the IVL procedure, there is a risk of tissue damage. Prolonged periods of reduced blood flow can compromise the health of surrounding tissues, especially in critical areas like the heart or the brain, where oxygen and nutrients are essential for proper function.
[6] Hence, there is a need to develop an intravascular lithotripsy device that maintains blood flow throughout the procedure and overcomes the aforementioned problems.

[22] The current disclosure pertains to a device for an intravascular lithotripsy (IVL) procedure (hereinafter, the procedure).
[23] Unlike a conventional IVL device, which temporarily obstructs blood flow during the procedure, the device of the present disclosure enables continuous blood circulation during the procedure. In an embodiment, the device includes a first tube and a second tube. A distal end of the second tube protrudes from a distal end of the first tube.
[24] In an embodiment, the device includes an inflatable balloon provided at a distal end of the device and coupled to the first tube and the second tube. The device includes at least one emitter provided on a portion of the second tube disposed inside the inflatable balloon. The inflatable balloon is expanded during the lithotripsy procedure. The at least one electrode is configured to generate acoustic pressure waves (or sonic waves) that help in creating microfractures in the calcified plaque. The inflatable balloon provides mechanical stability and helps in uniform energy distribution.
[25] In an embodiment, the second tube includes an aperture towards a proximal end. The second tube is configured to provide a passage for a body fluid (e.g., blood), while the inflatable balloon is expanded during the lithotripsy procedure, thereby, allowing continuous blood flow during the procedure. The body fluid enters the second tube from the distal end of the second tube and is discharged back into the blood vessel via the aperture of the second tube. By maintaining perfusion, the device significantly reduces the risk of ischemia and tissue damage, ensuring better patient safety and procedural outcomes. Thus, the device helps in treating calcified plaques without compromising blood supply to downstream tissues.
[26] Now referring to figures, Fig. 1a illustrates an intravascular lithotripsy (IVL) device 100 (hereinafter, device 100). The device 100 helps in treating calcified plaques without compromising blood supply to downstream tissues. The device 100 includes a proximal end 100a and a distal end 100b.

This allows a continuous blood flow in the vessel during the lithotripsy procedure. By maintaining perfusion, the device 100 significantly reduces the risk of ischemia and tissue damage, ensuring better patient safety and procedural outcomes. Thus, the device 100 helps in treating calcified plaques without compromising blood supply to downstream tissues.
[36] The aperture 310 may be formed on the second tube 300 using techniques, such as, without limitation, laser cut, trim and slit technique, etc. In an embodiment, the aperture 310 is formed on the second tube 300 using trim and slit technique.

In an embodiment, the distal end 500b of the inflatable balloon 500 is coupled to the outer surface of the second tube 300 using the same techniques that is used for coupling the proximal end 500a of the inflatable balloon 500 and the distal end 200b of the first tube 200.
[40] The outer surface of the second tube 300 is provided with at least one marker. The device 100 includes at least one marker provided on the portion 300c of the second tube 300.

[41] The inflatable balloon 500 is inflated at the target site with the help of an inflation fluid. The inflation fluid is introduced into the inflatable balloon 500 through the first lumen 210 of the first tube 200. The first lumen 210 of the first tube 200 provides a passage for an inflation fluid from the proximal end 200a of the first tube 200 into the inflatable balloon 500.
[42] In an embodiment, the device 100 includes a third tube 400, as shown in Fig. 4a. The third tube 400 includes a proximal end 400a and a distal end 400b. The third tube 400 is generally tubular in structure and is hollow from inside, thus defining a third lumen 400c. In an embodiment, the distal end 400b of the third tube 400 is beveled, though the distal end 400b may be unbeveled in another embodiment. In an embodiment, the third tube 400 is a hypo tube. The third tube 400 facilitates navigation of the device 100 through the tortuous pathways of the vessel. In an embodiment, the third tube 400 is made of medical grade-stainless steel 304 (SS304), though it may be made of any other suitable material.
[43] In an embodiment, a proximal portion towards the proximal end 200a of the first tube 200 is disposed within the third lumen 400c and is coupled to the third tube 400 (as shown in Fig. 4a). The third lumen 400c extends between the proximal end 400a and the distal end 400b of the third tube 400.

In an embodiment, the distal end 400b of the third tube 400 is coupled to the proximal end 200a of the first tube 200. The distal end 400b of the third tube 400 may be coupled to the proximal end 200a of the first tube 200 using techniques, such as, without limitation, thermal bonding, adhesive bonding. In an embodiment, the distal end 400b of the third tube 400 is coupled to the proximal end 200a of the first tube 200 using thermal bonding. An outer diameter of the first tube 200 is selected such that it is equal to or less than a diameter of the third lumen 400c. The diameter of the third lumen 400c may range between 0.82 mm and 0.88 mm. In an embodiment, the diameter of the third lumen 400c is 0.85 mm.
[44] The third lumen 400c of the third tube 400 is configured to provide passage for the inflation fluid from an inflation fluid reservoir into the inflatable balloon 500 via the first lumen 210 of the first tube 200 to inflate the inflatable balloon 500. The proximal end of the third tube 400 is coupled to the inflation fluid reservoir via a port (not shown).
[45] A length of the third tube 400 may range between 1248 mm and 1252 mm. In an embodiment, the length of the third tube 400 is 1250 mm. In an embodiment, the third tube 400 is made of medical grade stainless steel 304, though it may be made of any other suitable biocompatible material.
[46] The device 100 includes at least one emitter 330 (hereinafter, emitter 330) and at least one insulator 332 (hereinafter, insulator 332). In an embodiment, the portion 300c of the second tube 300 includes two emitters 330 and two insulators 332. The emitters 330 and the insulators 332 are provided on the outer surface of the portion 300c of the second tube 300.
[47] The emitters 330 and the insulators 332 are provided between the markers 320. Each insulator 332 is provided beneath a respective emitter 330 of at least one emitter 330. Each emitter 330 is mounted on the respective insulator 332. The emitters 330 help in decalcifying the calcified portion in the vasculature. The emitters 330 operate at a predefined frequency of sonic waves. The predefined frequency may range between 0.9Hz and 1.0Hz.
[48] The emitters 330 are electrically coupled to a power source 700 using at least one connecting wire 600 (hereinafter, connecting wire 600), as shown in Figs. 4a-4b. In an embodiment, the connecting wire 600 extend between the emitters 330 and the power source 700 provided at the proximal end 100a of the device 100. The connecting wire 600 are disposed within the first lumen 210 of the first tube 200 and the third lumen 400c of the third tube 400. The connecting wire 600 is configured to electrically couple the at least one emitter 330 with the power source 700. In an embodiment, the emitters 330 act as transducers. The emitters 330 are configured to generate controlled acoustic pressure waves upon receiving an electric current from the power source 700. The at least one emitter 330 is configured to generate sonic waves at a predefined frequency upon receiving electric power from the power source 700. This initiates the lithotripsy procedure, producing circumferential sonic waves that travel through the soft tissues but specifically break hard calcified structure. The insulators 332 are configured to isolate the emitters 330 from the second tube 300, ensuring controlled energy delivery while preventing unintended conduction throughout the second tube 300.
[49] During the procedure, a surgeon may insert the distal end 100b of the device 100 into the patient’s body. The inflatable balloon 500 of the device 100 is in a deflated state during the insertion of the distal end 100b of the device 100. The device 100 is advanced through the vessel towards a target region. The inflatable balloon 500 remains deflated at this stage. The inflatable balloon 500 is placed at the target region with the help of the at least one marker. The at least one marker helps in aligning the inflatable balloon 500 at the target site using any imaging guidance. Once the inflatable balloon 500 is positioned at the target site, the inflation fluid is introduced in the inflatable balloon 500 via the third lumen 400c of the third tube 400 and the first lumen 210 of the first tube 200 to inflate/expand the inflatable balloon 500.
[50] Thereafter, an electric power is supplied to the emitters 330 from the power source 700. Upon receiving the electrical power, the emitters 330 generating circumferential shockwaves, thus initiating the lithotripsy procedure. These waves propagate through soft tissues while precisely targeting and breaking hard calcified structures in the vessel. While the decalcification procedure is carried out, the blood from the vessel enters into the second lumen 300d of the second tube 300 and oozes out of the aperture 310 and the first hole 220 (as shown in Fig. 5), thereby, allowing continuous blood flow within the vessel throughout the procedure.
[51] The scope of the invention is only limited by the appended patent claims. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the teachings of the present invention is/are used. , Claims:WE CLAIM
