简要总结
The InSeal vascular closure device (VCD) is assessed as percutaneous closure of artery access sites for quick hemostasis and ambulation in patients who have undergone large bore endovascular catheterization procedures.
The study hypothesis is that the VCD is safe and efficient in achieving hemostasis in the study population.
详细描述
The increasing variety of arterial devices having a large crossing profile requiring the use of a large bore sheath is mandating focus on large bore closure. Such procedures include endovascular abdominal repair (EVAR), thoracic (TEVAR) aortic repairs and transcatheter aortic valve implantation (TAVI) typically involve sheaths and delivery catheters with 14-25Fr profiles.
Today, the typical closing technique (labeled in Europe) for such large sheath size is a one where sutures are deployed prior to the insertion of the large sheath with the sutures tied at the end of the procedure. This technique is cumbersome, hard to learn, complex to use and has relative high complications and failure rate.
The InSeal VCD device model 13-517, is easy to use, fast, affords immediate reliable hemostasis, and supports a wide range of sheath punctures size and artery's dia. 6-10 mm, while leaving a minimal amount material behind and will not limit re-access.
While each of these features may be found in one commercial device or another, to date there is no single device that meets all the market requirements.
