SYSTEMS AND METHODS FOR TREATING A CAROTID ARTERY
Systems and methods are adapted for treating the carotid artery. The systems include interventional catheters and blood vessel access devices that are adapted for transcervical insertion into the carotid artery. Embodiments of the systems and methods can be used in combination with embolic protection systems including blood flow reversal mechanisms, arterial filters, and arterial occlusion devices.
1 - 16 . (canceled)
17 . A device for closing an arteriotomy, comprising:
a base body having an opening formed therein, the opening being sized and configured for a procedural device to be passed therethrough;
one or more prongs extending from the base body;
wherein the one or more prongs are configured to shift between an open configuration and a closed configuration;
a retaining ring coupled to the base body, the retaining ring being configured to retain the one or more prongs in the open configuration; and
a sealing member configured to be coupled to the one or more prongs.
18 . The device of claim 17 , wherein the retaining ring has a securing region configured to be secured to a tether.
19 . The device of claim 18 , wherein the securing region includes an eyelet.
20 . The device of claim 18 , wherein the tether can be pulled to uncouple the retaining ring from the base body.
21 . The device of claim 20 , wherein uncoupling the retaining ring from the base body shifts the one or more prongs to the closed configuration.
22 . The device of claim 21 , wherein shifting the one or more prongs to the closed configuration secures the sealing member to the one or more prongs.
23 . The device of claim 17 , wherein the one or more prongs are biased to be in the closed configuration.
24 . The device of claim 17 , wherein the base body includes an annular ring.
25 . The device of claim 17 , wherein the base body include an upper clip member and a lower clip member.
26 . A device for closing an arteriotomy, comprising:
a base having an opening formed therein, the opening being sized and configured for a procedural device to be passed therethrough;
wherein the base includes one or more tissue-engaging members;
a sealing member configured to be coupled to the base;
wherein the base is configured to shift between an open configuration and a closed configuration;
wherein the sealing member is secured to the base when the base is in the closed configuration; and
a retaining ring coupled to the base, the retaining ring being configured to retain the base in the open configuration.
27 . The device of claim 26 , wherein the retaining ring has a securing region configured to be secured to a tether.
28 . The device of claim 27 , wherein the securing region includes an eyelet.
29 . The device of claim 27 , wherein the tether can be pulled to uncouple the retaining ring from the base.
30 . The device of claim 29 , wherein uncoupling the retaining ring from the base shifts the base to the closed configuration.
31 . The device of claim 26 , wherein the base is biased to be in the closed configuration.
32 . The device of claim 26 , wherein the base includes an annular ring.
33 . The device of claim 26 , wherein the base include an upper clip member and a lower clip member.
34 . A method for closing an arteriotomy, the method comprising:
coupling a closure device to an arteriotomy opening, the closure device comprising:
a base having an opening formed therein,
wherein the base includes one or more tissue-engaging members,
a sealing member configured to be coupled to the base,
wherein the base is configured to shift between an open configuration and a closed configuration,
wherein the sealing member is secured to the base when the base is in the closed configuration, and
a retaining ring coupled to the base, the retaining ring being configured to retain the base in the open configuration;
advancing a procedural device through the opening in the base;
performing a procedural intervention with the procedural device;
removing the procedural device from the opening in the base; and
uncoupling the retaining ring from the base to shift the base to the closed configuration.
35 . The method of claim 34 , wherein the retaining ring has a securing region configured to be secured to a tether and wherein uncoupling the retaining ring from the base includes pulling the tether.
36 . The method of claim 34 , wherein the procedural device includes an expandable balloon, a stent, or both an expandable balloon and a stent.
