The intervention utilizes the Vascular Suture System (Model: SPD-100) developed by Suzhou Hengrui Hongyuan Medical Technology Co., Ltd., composed of a vascular suturing device and a suture trimmer. It is intended for closing percutaneous vascular puncture sites in patients undergoing interventional catheter diagnosis or treatment. For femoral artery punctures, it is compatible with 5F-21F sheaths (for sheaths \>8F, at least 2 devices and pre-embedded suture technology are required); for femoral vein punctures, it suits 5F-24F sheaths (for sheaths \>8F, at least 1 device and pre-embedded suture technology are needed).

The intervention employs the Perclose ProGlide Vascular Closure System (Model: 12673) manufactured by Abbott, a clinically validated device for closing percutaneous vascular puncture sites. It is indicated for patients undergoing interventional catheter diagnosis or treatment via femoral artery puncture with 5F-21F sheaths, serving as the control in this prospective, multi-center, randomized controlled trial. The device operates by percutaneously delivering sutures through a guidewire: during or after surgery, it accesses the puncture site, deploys sutures to approximate the vascular wall, and secures the suture knot to achieve hemostasis, with the suture permanently implanted in the body.
