Abstract
Vessel wound closure systems and method for sealing a puncture wound in a target vessel, such as those puncture wounds that occur from interventional procedures. The vessel wound closure system comprises at least a biocompatible, viscoelastic, self-sealing septum material injected onto the adventitia of the target vessel prior to performance of an interventional procedure. The prior injected septum material remains and seals the puncture wound of the target vessel even after various components associated with accessing the target vessel and the performance of the interventional procedure are removed from the target vessel and the puncture wound.
Claims12
A vessel wound closure system used prior to performance of an interventional procedure in a target vessel, comprising:
- a self-sealing septum material adapted to be disposed onto adventitia of the target vessel;
- and
- a stepped needle comprising a smaller diametered distal portion and a larger diametered proximal portion, the smaller diametered portion comprising a pointed tip configured to pierce through the adventitia of the target vessel to allow the larger diametered portion to externally abut the adventitia of the target vessel, the larger diametered portion comprising at least one opening formed in a side wall thereof, through which the self-sealing septum material is disposed onto the adventitia of the target vessel.
