Abstract
An implantable purse string suture tensioning device is provided, such that a hemostatic seal can be maintained without further manual adjustment over a range of purse string circumferences, including that surrounding a minimally invasive device, or a control or guidewire, and after complete removal of objects within the purse string suture, wherein the device is sized and shaped for in-dwelling implantation in a patient.
Claims25
An implantable purse string suture tensioning device comprising:
- a) at least one compressible tensioning element having a proximal end and a distal end;
