PROSTHESIS FOR REPAIRING A HERNIA DEFECT

摘要

A prosthesis for repairing a hernia defect includes a patch body, a hoisting frame releasably attachable to the patch body, and a tether attached to the hoisting frame and having a free end extendable through the thickness of the patch body and accessible from the side of the patch body opposite to the side where the hoisting frame is releasably attached. The patch body and/or the hoisting frame includes a self-expanding support member. The hoisting frame includes a frame body and a translation component for directing pulling forces on the tether to the frame body.

主权项

1. A prosthesis for repairing a hernia defect, comprising:
a patch body having a periphery, a first axis and a second axis perpendicular to the first axis, the first axis and the second axis intersecting at approximately a center of the patch body, an upper portion of the patch body on one side of the first axis and a lower portion of the patch body on the other side of the first axis; a self-expanding support member to assist in unfurling the patch body from the reduced configuration to an expanded configuration, the self-expanding support member including a first portion that is positionable on the upper portion of the patch body and a second portion that is positionable on a lower portion of the patch body; a hoisting frame releasably attachable to the patch body, the hoisting frame defining an open interior and including a translation component extending through the open interior; and a tether attached to the translation component, a free end of the tether extendable away from the translation component and through the patch body when the hoisting frame is releasably attached to the patch body, a pulling force on the free end of the tether in an outward direction away from the patch body being directed by the translation component in the direction of a first pair of spaced apart locations on opposite sides of the second axis at the upper portion of the patch body when in the expanded configuration and a second pair of spaced apart locations on opposite sides of the second axis at the lower portion of the patch body; wherein the patch body and the hoisting frame when releasably attached to the patch body are manipulable into a reduced configuration for insertion through a narrow incision or cannula into a patient.
