Study type
Interventional
Description of intervention(s) / exposure
Patients enrolled in this study with all eligibility criteria confirmed will be implanted with the TriCinch Coil System. This device offers a percutaneous treatment (access through the vein at the groin) to treat the leaking tricuspid valve, without the need for surgical intervention. This procedure is done by an interventional cardiologist or a cardiac surgeon under a general anaesthetic or deep sedation without the need for respiratory assistance and is expected to last 60-90 minutes initially.
The TriCinch Coil System implantation is as follows: 1) A delivery system that consists of a catheter (a hollow tube) that is attached to a handle is inserted in the patient's body through a vein in the groin. The delivery system contains a small anchor and a stent.
2) The small anchor is permanently placed in the wall of the tricuspid valve. The anchor is connected to a tensioning band that is connected to a stent at the opposite end. The stent (a mesh-like metal tube that expands, when deployed, to fit the patient's anatomy) is permanently deployed in a large vein called the inferior vena cave (IVC).
3) Then, the delivery system is removed and the procedure is complete.

Summary
Brief summary
The purpose of this clinical study is to evaluate a new, medical device called the TriCinch Coil System. This is an early phase study. This device is designed to treat patients suffering from tricuspid valve disease, It has not been approved by the Therapeutic Goods Administration (TGA) as a treatment for tricuspid valve regurgitation in Australia.,
The study is a multi-centre study, which means that up to 20 hospitals may be participating in this study. Implantation of the TriCinch Coil System will be attempted in up to 90 patients in this study.
The goal of this clinical study is to evaluate the safety and performance of the TriCinch Coil System as a new method to treat leaking tricuspid valves which cause regurgitation (backflow of blood). Through the trial, information will be collected about the safety of the device, the success of placing the device, and its ability to reduce tricuspid regurgitation in a less invasive way for patients who have a high risk for undergoing open-heart surgery.
