Abstract
The disclosure provides a dynamic vascular access and closure device for radial cinching of an access site. The device includes a tensioning tube, a resilient member disposed within the tensioning tube, and a plurality of sutures extending axially between a distal end of the tensioning tube and a proximal end of the tensioning tube. A proximal end of each of the plurality of sutures can be configured to attach to the resilient member such that movement of that suture causes compression or extension of the resilient member within the tensioning tube to provide cinching to the sutures.
Core Innovation
The invention relates to a dynamic percutaneous vascular access and closure system that uses a cinching device with a tensioning tube containing a resilient member. A plurality of sutures extends axially between a distal end and a proximal end of the tensioning tube, and proximal ends of the sutures directly couple with the resilient member, such that movement of the sutures causes compression or extension of the resilient member within the tensioning tube.
This arrangement enables reversible opening or closing of a vascular access site within a blood vessel via the sutures. The system enables cinching by attaching the distal ends of the plurality of sutures at least partially around the vascular access site, and retracting a medical device causes dynamic and reversible cinching of the vascular access site situated between the distal ends of the sutures.
After dynamic and reversible cinching, the device optionally supports irreversible closure by deploying a suture lock. The disclosed approach also supports dynamic reopening for repeat access, with alternative configurations including different internal arrangements such as a force applicator or inner biasing tube, resilient member stops, and anchor-based versus non-anchor suture placement.
Claims Coverage
The independent claim covers a method of cinching a vascular access site using a cinching device that couples suture movement to compression or extension of a resilient member within a tensioning tube, thereby enabling reversible opening or closing. Based on the provided claim text, there is 1 independent claim, with several dependent claims adding inventive features.
Dynamic reversible cinching using a resilient member tensioning tube
Providing a cinching device comprising a tensioning tube comprising a resilient member disposed within the tensioning tube; and a plurality of sutures extending axially between a distal end of the tensioning tube and a proximal end of the tensioning tube, wherein a proximal end of each of the plurality of sutures is configured to directly couple with the resilient member such that movement of the plurality of sutures causes compression or extension of the resilient member within the tensioning tube, and wherein the compression or extension of the resilient member enables, via the plurality of sutures, reversible opening or closing of the vascular access site within a blood vessel.
Device insertion and retraction causing dynamic reversible cinching
Attaching distal ends of the plurality of sutures at least partially around the vascular access site; inserting a medical device into the vascular access site; retracting the medical device from the access site, the retracting causing dynamic and reversible cinching of the vascular access site situated between the distal ends of the plurality of sutures by compression or extension of the resilient member within the tensioning tube.
The claim coverage is centered on reversibly opening and closing a vascular access site by coupling movement of sutures to compression and extension of a resilient member inside a tensioning tube, and on achieving dynamic reversible cinching during retraction of a medical device from between suture distal ends.
