During such procedures, a small incision is made in the groin area and a hole is created in the femoral artery to gain access to the artery. This hole is referred to as the access site or puncture site. At the completion of the procedure, the hole needs to be closed.
The Mynx Vascular Closure Device is an extravascular vascular closure device (VCD) whose deployment system is designed to minimize the discomfort commonly associated with closing the small hole in the artery following catheterization procedure. The device is manufactured by AccessClosure, Inc., a medical device company located in Mountain View ...
A drug-eluting stent (DES) is a small mesh tube that is placed in the arteries to keep them open in the treatment of vascular disease.The stent slowly releases a drug to block cell proliferation (a biological process of cell growth and division), thus preventing the arterial narrowing that can occur after stent implantation.
After the balloon inflation/deflation or the deposition of the stent, the placement device/deflated balloon are removed leaving the stent in place. [21] [22] The interventional cardiologist decides how to treat the blockage in the best way during the PCI/stent placement, based on real-time data.
A ureteral stent (pronounced you-REE-ter-ul), or ureteric stent, is a thin tube inserted into the ureter to prevent or treat obstruction of the urine flow from the kidney. The length of the stents used in adult patients varies between 24 and 30 cm. Additionally, stents come in differing diameters or gauges, to fit different size ureters.
Diagram of stent placement. In A, the catheter is inserted across the lesion. In B, the balloon is inflated, expanding the stent and compressing the plaque. In C, the catheter and deflated balloon have been removed. Before-and-after cross sections of the artery show the results of the stent placement. Arterial Stenting 3D Medical Animation
The first device was simple, according to Parodi: "It was a graft I designed with expandable ends, the extra-large Palmaz stent, a Teflon sheath with a valve, a wire, and the valvuloplasty balloon, which I took from the cardiologists." Parodi's first patient lived for nine years after the procedure and died from pancreatic cancer.
Cardiac catheter placement through the groin. Cardiac catheterization is the insertion of a catheter into the heart through a blood vessel. The cardiac catheter can then be used to run tests and perform other procedures. Such procedures are stent placement, angioplasty, fractional flow reserve, intravascular ultrasound (IVUS) and cardiac biopsy ...
