The disclosed technology provides a device for sealing an aperture in a tissue of a body lumen. The device comprises a flexible support member having a base having (i) a central portion and (ii) one or more lateral support portions, to engage and/or hold a sealable member of the device against an interior surface of the tissue when the device is in the sealing position. The lateral support portions provide additional support surfaces to engage peripheral portions of the sealable member against the interior surface of the tissue. A cage or shoe engaged with the support member on the exterior surface of the tissue can provide additional support and assist sealing the aperture.

Arteriotomy closure apparatus with slotted shoe for advantageous pressure distribution

The present invention relates generally to a closure system for use in surgical procedures.

Closure system and uses thereof

The disclosed technology provides a device () for sealing an aperture in a tissue of a body lumen. The device includes a flexible support member () having a base () configured to engage and/or hold a sealable member () of the device against an interior surface of the tissue when the device is in the sealing position. The device also includes a locator () coupled to the support member and configured to engage with a wall of the body lumen to secure the device thereto.

Adjustable vascular closure device

The disclosed technology provides a device for sealing an aperture in a tissue of a body lumen. The device comprises a flexible support member having a base having (i) a central portion and (ii) one or more lateral support portions, to engage and/or hold a sealable member of the device against an interior surface of the tissue when the device is in the sealing position. The lateral support portions provide additional support surfaces to engage peripheral portions of the sealable member against the interior surface of the tissue.

Closure apparatus with flexible sealable member and flexible support member

A device for sealing an aperture in a tissue includes: a foot including a distal portion configured to be disposed distal to the tissue when the device is implanted in a position to seal the aperture; and a flexible wing positionable against a distal surface of the tissue adjacent the aperture such that the flexible wing is disposed between the distal portion of the foot and the distal surface adjacent the aperture.

Implants and methods for percutaneous perforation closure

The provided technologies provide an implant closure device having a mesh layer formed on a flexible substrate, collectively forming a sealable member, that improves a seal formed over an aperture in a body lumen. The mesh facilitates a faster and more secure adherence of the sealable member to the surrounding edges at the puncture site. Furthermore, the provided technology may promote platelet-capture and encourage localized platelet aggregation at the exposed collagen in the wound edges on the mesh layer. The platelet impregnated mesh layer can facilitate cellular adhesion, enabling the sealable member that is local to the wound opening to act, in essence, as a 'biological glue.'

A device for sealing an aperture in a tissue includes: an implant configured to seal the aperture when positioned adjacent to the aperture; and a delivery shaft configured to engage the implant to allow the implant to be maneuvered into sealing engagement with a distal surface of the tissue, the delivery shaft comprising a retaining sleeve comprising a locking projection engagable with the locking recess of the implant to secure the implant to the delivery shaft, and a release sleeve axially slideable relative to the retaining sleeve between a first axial position in which the release sleeve is configured to maintain locking engagement between the locking recess and the locking projection, and a second axial position in which the release sleeve permits the locking projection to disengage the locking recess.
