US 2014/0236225 A1 · BIOADHESIVE DELIVERY SYSTEMS AND METHODS FOR VASCULAR CLOSURE

Abstract

A vascular closure system includes a balloon location device, a bioadhesive delivery device, and a sealing tip. The balloon location device includes a balloon for temporarily sealing a vessel puncture internally and at least one lumen for delivering inflation fluid to the balloon. The bioadhesive delivery device includes at least one lumen for delivery of the balloon location device to the vessel puncture. One of the balloon location device and the bioadhesive delivery device includes a first lumen for delivery of a first volume of bioadhesive to the vessel puncture. The sealing tip is releasable within a channel formed in the first volume of bioadhesive upon withdrawal of the balloon. One of the balloon location device and the bioadhesive delivery device is configured for delivery of a second volume of bioadhesive to the vessel puncture after the sealing tip is released in the channel.

Dependent claims

A vascular closure system, comprising:

a balloon location device having a balloon for temporarily sealing a vessel puncture internally, the balloon location device comprising at least one lumen for delivering inflation fluid to the balloon;
a bioadhesive delivery device having at least one lumen for delivery of the balloon location device to the vessel puncture, wherein one of the balloon location device and the bioadhesive delivery device includes a first lumen for delivery of a first volume of bioadhesive to the vessel puncture;
a sealing tip carried by the balloon location device at a location distal of the balloon and being releasable within a channel formed in the first volume of bioadhesive upon withdrawal of balloon;
wherein one of the balloon location device and the bioadhesive delivery device is configured for delivery of a second volume of bioadhesive to the vessel puncture after the sealing tip is released in the channel.

A vascular closure device, comprising:

a bioadhesive delivery device having at least one lumen;
a balloon location device having a balloon carried at a distal end thereof and at least one lumen, the balloon location device being insertable through the at least one lumen of the bioadhesive delivery device to position the balloon through a vessel puncture, the balloon being expandable to temporarily seal the vessel puncture internally;
wherein one of the bioadhesive delivery device and the balloon location device is configured for delivery of a first volume of bioadhesive to the vessel puncture through one of the at least one lumens, and one of the bioadhesive delivery device and the balloon location device is configured for delivery of a second volume of bioadhesive to the vessel puncture through another of the at least one lumens.

A method of closing a vessel puncture in a wall of a vessel, comprising:

providing a bioadhesive delivery device and a balloon location device each having at least one lumen, a balloon carried by the balloon location device, and a sealing tip carried at a distal end of the balloon location device;
advancing the balloon location device through the at least one lumen of the bioadhesive delivery device and through the vessel puncture to position the balloon within the vessel;
inflating the balloon and contacting the balloon against an inner surface of the vessel to temporarily seal the vessel puncture;
delivering a first volume of bioadhesive through one of the at least one lumen of the bioadhesive delivery device and the at least one lumen of the balloon location device;
deflating the balloon and withdrawing the balloon through the first volume of bioadhesive;
depositing the sealing tip in the first volume of bioadhesive;
delivering a second volume of bioadhesive through another one of the at least one lumen of the bioadhesive delivery device and the at least one lumen of the balloon location device at a location proximal of the first volume of bioadhesive.
