Filed:

Jul 16, 2021

Appl. No.:

17/378097

Inventors:

- Mansfield MA, US
Hillary K. Huszar - Redwood City CA, US
Mark A. Maguire - Hillsborough CA, US
Shawn C. Daniel - San Jose CA, US

International Classification:

A61F 2/966
A61F 2/91
A61F 2/07

Abstract:

Methods, apparatuses and systems are described for expandable stent delivery apparatus to cover an access site. The method may include delivering the stent through an access site and deploying a distal portion of the stent from within an outer sheath. In some cases, the method may further include pushing a proximal portion of the stent from the outer sheath such that upon fully exiting the outer sheath, the proximal portion extends proximally to at least partially cover the access site with the stent. The system for delivering the stent into the body lumen may include a stent, a stent delivery apparatus, and an outer sheath. The system may further include an internal pusher configured to push a proximal portion of the stent from the outer sheath and axially compress the stent such that upon fully exiting the outer sheath, the proximal portion extends proximally to cover the access site.

International Classification:

A61F 2/966

A61F 2/07

Abstract:

Methods, apparatuses and systems are described for stent delivery and positioning to cover an access site. A stent delivery system may include a tubular member configured to advance through an access site and a primary constrainment member configured to releasably couple the stent to the tubular member. The stent delivery system may further include a secondary constrainment member at least partially disposed around the primary constrainment member, the stent, and the tubular member. In some cases, the tubular member and the primary constrainment member may be configured to reposition the stent within the body lumen after removal of the secondary constrainment member such that at least a portion of the stent covers the access site after withdrawal of the tubular member, the primary constrainment member, and the secondary constrainment member from the body lumen through the access site.

International Classification:

A61F 2/07

Abstract:

Methods, apparatuses and systems are described for expandable stent delivery apparatus to cover an access site. The method may include delivering a stent delivery system through an access site, where the stent delivery system comprises a positioning member with a first portion that is rotatable with respect to a second portion, and where the stent is releasably coupled with the first portion of the positioning member. In some cases, the method may further include withdrawing an outer constrainment member front the stent to deploy a proximal portion of the stent within the body lumen and rotating the proximal portion of the stent away from the access site by withdrawing the positioning member proximally and back through the access site. The method may further include covering the access site with the proximal portion of the stent upon fully deploying the proximal portion from the outer constrainment member.

International Classification:

A61F 2/966
A61F 2/91
A61F 2/07

Abstract:

Methods, apparatuses and systems are described for delivering a stent through an access hole of a body lumen and covering up the access hole after deploying the stent. Stents are described that include a stent body defining a body lumen contact surface area and a deployable member configured to deploy from the stent body and increase the body lumen contact surface area of the stent. Deployable members that hinge, unroll, extend, expand, and coaxially translate with respect to the stent body are described. A system for delivering a stent into a body lumen are described that may include a coverage member configured to at least partially cover the hole in the wall of the stent upon withdrawing a tubular member through the hole in the wall of the stent. Coverage members may include a self-sealing membrane, a flap valve, or a hinged valve.

International Classification:

A61F 2/07

Abstract:

Methods, apparatuses and systems are described for stent delivery and positioning to cover an access site. The method may include delivering the stent through an access site in a wall of the body lumen. In some cases, the method may include repositioning the stent within the body lumen to at least partially cover the access site with the stent. The stent may be repositioned within the body lumen by retracting the stent towards the access site such that a proximal portion of the stent at least partially covers the access site. The stent may then expand within the body lumen. In some cases, the stent may expand within the body lumen by releasing a primary constrainment member from the stent by pulling the primary constrainment member in a proximal direction away from the stent.
