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.

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.

Abstract: A surgical system for use in repairing a wound after an endoscopic resection procedure includes a plurality of anchors coupled to one another via a tether. Each of the anchors includes a head defining an opening for receipt of the tether, and two or more tines configured to penetrate tissue. The tines are resiliently biased toward a deployed configuration, in which the tines project outwardly relative to the head and assume an arcuate shape.

Abstract: A surgical system for performing an endoscopic submucosal dissection includes first and second surgical clips each having first and second jaw members for grasping tissue therebetween. The first surgical clip includes a resilient member attached to one of the jaw members and configured to bow outwardly to engage tissue. The jaw members of the first surgical clip each has a pointed tip and each of the jaw members of the second surgical clip has a blunt distal tip.

Abstract: A tissue clip includes an elongate body configured to be detachably coupled to a shaft of a surgical instrument, a pair of jaw members received in the elongate body, and a resilient member configured to bow outwardly from the elongate body upon deployment of the tissue clip at a surgical site.

The hemostatic clip has an elongated collar configured to be detachably coupled to a shaft of the surgical instrument, a pair of jaws received in the collar, and a magnet coupled to the jaws.

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.

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.
