The following specification particularly describes the invention and the manner in which it is to be performed:

 
FIELD OF INVENTION
[001] The present invention relates to a medical implant. More specifically, the present invention relates to an arteriovenous (AV) fistula implant.
BACKGROUND OF INVENTION
[002] Chronic kidney diseases result in a gradual loss of kidney function over time. Thus, resulting in a dangerous level of waste, electrolyte and/or fluid build-up inside a patient’s body. The waste and/or fluid buildup may lead to complications such as, high blood pressure, heart disease, etc. and can eventually cause kidney failure.
[003] Generally, people suffering from chronic kidney disease are treated with the process of hemodialysis, which includes filtering the blood by removing waste components such as creatine, urea and/or other impurities from the blood.
[004] Hemodialysis requires access to the vasculature system on a regular basis. Since veins are too fragile and arteries are too deep to provide regular access, an arteriovenous (AV) fistula is typically created using a surgical procedure. The AV fistula is depicted in Fig. 1. An AV fistula is a surgical connection between an artery and a vein. However, there are several complications associated an AV fistula such as, narrowing of the fistula due to tissue overgrowth (stenosis), formation of blood clot within the fistula (thrombosis), bulging or weakening of the fistula wall as a result of high blood flow through the fistula, etc. Further, there are multiple complications faced during surgeries due to variability in size of arteries and veins in patients.
[005] Conventional methods include, maturation process wherein after the fistula is created, the body naturally responds by enlarging the vein to accommodate the increased blood flow from the artery. However, many a times the vein does not enlarge in a predefined time causing failed maturation. Thus, resulting in a slow blood flow in the artery for an effective dialysis.
[006] Further, due to lack of sufficient support to the artery and vein of the AV fistula, blood flowing in the blood vessels (herein, arteries and veins) may cause turbulence. Thus, damaging the inner lining of the blood vessels and increasing the risk of complications such as, thrombosis, stenosis etc. Moreover, multiple complications are faced during surgeries due to variability in size of arteries and veins in patients. Many a times, devices used at the time of surgery are not optimally sized for specific artery and vein of the patient. Thus, leading to a poor fit of the device resulting in improper blood flow or failure to support the AV fistula adequately.
[007] Hence, there is a need of an implant which can have adaptability to handle variations in size of arteries and veins, based upon a patient’s anatomy.

[0020] In accordance with the present disclosure, an AV (arteriovenous) fistula implant (hereinafter, an implant) is disclosed. The implant is used in various vascular surgeries to create and maintain the AV fistula. The implant is placed around the artery and vein of the AV fistula of a patient.
[0021] The implant of the present disclosure includes a T-shaped component and a tubular mesh. The T-shaped component and the tubular mesh of the implant provide support to the corresponding artery and vein. Thus, reducing turbulence and minimizing the risk of stenosis (narrowing) at the AV fistula site. In an embodiment, the T-shaped component includes one or more clamps that ensure adjustability of the implant according to the specific size requirements. The size adjustability of the implant allows surgeons to make corrections during surgery, minimizing the likelihood of AVF failure. The adjustability of the size of the implant corresponding to the surgical requirements of the patient (for example, diameter of the vein, artery, etc.) reduces the need for multiple device variants and simplifies inventory management. Also, the adjustability of the implant reduces the need for reoperations due to improper device fit or performance. Further, the implant enhances the maturation and function of AVF, ensuring efficient blood flow for dialysis. Thus, the implant addresses AVF failure by promoting long-term patency and stable dialysis access.
[0022] Though the implant of the present disclosure is explained with respect to an AV fistula of a patient, it can be extended to any anastomosis site of the human body. More specifically, in the present disclosure, the implant is explained with respect to a side of end AV fistula wherein, a side of an artery is cut and stitched with an end of a vein.
