Device and method for deploying and attaching an implant to a biological tissue

摘要

This present invention generally relates to devices and methods for repairing an aperture in a biological tissue. In certain embodiments, the invention provides a system for closing an aperture in a biological tissue including a handle, an elongate shaft connected to the handle, and a deployment scaffold connected to the shaft, in which the scaffold is configured to releasably retain a surgical implant and the scaffold is configured to deploy and attach the surgical implant to the biological tissue.

主权项

1. A system for closing an aperture in a biological tissue, the system comprising:
a handle; an elongate shaft connected to the handle, the elongate shaft having a longitudinal axis extending therethrough; a central shaft disposed within the elongate shaft; and a deployment scaffold connected to the elongate shaft and the central shaft such that movement of the central shaft with respect to the elongate shaft transitions the deployment scaffold between open and closed forms, wherein movement of the central shaft towards the handle transitions the deployment scaffold to the open form and the scaffold is configured to releasably retain a surgical implant and the scaffold is configured to deploy and attach the surgical implant to the biological tissue, the surgical implant releasable from the deployment scaffold in a radial direction relative to the longitudinal axis when the deployment scaffold is parallel to the longitudinal axis, wherein the deployment scaffold includes: a plurality of deployment arms that are configured to move from a retained position to at least one deployed position; and a plurality of attachment members that are releasably connected to the deployment arms, wherein the attachment members attach the surgical implant to the biological tissue.
