Implantable purse string suture tensioning device
First Claim
Patent Images
1. An implantable purse string suture tensioning device comprising:
- at least one compressible tensioning element having a proximal end and a distal end;
a suture guide element having a proximal surface and a distal surface and at least one passage therethrough for receiving a purse string suture, wherein the suture guide element comprises a plurality of telescoping elements which, when in use, permits a variable length of a suture to pass therethrough and stabilizes a suture adjacent to the tensioning element to permit absorption of excess suture length under predetermined pressure of the tensioning element to maintain tension in the suture; and
wherein the device is sized and shaped for in-dwelling implantation in a patient.

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.

22. An implantable purse string suture tensioning device comprising:
-
a guide element having a proximal surface and a distal surface and at least one passage there through, for receiving a purse string suture, wherein the suture guide element comprises a plurality of telescoping elements which, when in use, permits a variable length of a suture to pass therethrough and absorbs excess suture length under predetermined pressure to maintain tension in the suture, a tensioning element having a first lateral end and a second lateral end, the tensioning element applying the predetermined pressure, a plurality of passage elements, one attached to each end of the tensioning element, for receiving a respective end of a purse string suture; wherein the device is sized and shaped for in-dwelling implantation in a patient. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. An implantable purse string suture tensioning device comprising:
-
at least one compressible tensioning element; and a suture guide element having at least one passageway for receiving a purse string suture, the suture guide element comprising first and second elements arranged in spaced apart telescopic arrangement, the at least one passageway formed between the first and second elements for receiving a purse string suture of variable length, wherein the tensioning element is configured to alter an extent of the spaced apart telescopic arrangement of the first and second elements thereby absorbing excess purse string suture length under a pre-determined pressure of the tensioning element throughout changes in the purse string suture length and maintaining tension in the suture. - View Dependent Claims (38, 39)
