1. A surgical device, comprising:
- a plurality of anchors;
a plurality of sutures, each of the plurality of anchors having one of the sutures coupled thereto; and
an elongate shaft having a tissue-penetrating tip at a distal end thereof, a plurality of channels formed in the elongate shaft each configured to seat one of the plurality of anchors, and an inner lumen isolated from the plurality of channels and extending through the elongate shaft, the sutures each at least partially extending through the inner lumen, and the plurality of channels being configured such that upon insertion of the shaft through tissue each of the anchors can be selectively retracted proximally relative to the shaft by pulling the suture coupled thereto to release the anchor from the channel in which the anchor is seated and engage tissue with the suture coupled thereto extending through the tissue.

Abstract
Methods and devices are provided for deploying and applying multiple suture anchors. In one embodiment, a surgical device is provided having a shaft configured to be introduced into a body, e.g., through a scoping device, and to deliver a plurality of suture anchors into tissue, preferably without the need to remove the shaft from the body. The shaft can have a plurality of channels, with each of the plurality of channels configured to seat at least one of a plurality of suture anchors. Each of the anchors can be removably seated in a channel such that the anchors can be removed from the device, such as by pulling on sutures attached to the respective anchors.

17. A surgical device, comprising:
-
an elongate flexible shaft having proximal and distal ends; a handle at the proximal end of the elongate shaft; and a plurality of suture anchors disposed within a distal portion of the shaft, each suture anchor having a length of suture extending therefrom, each of the plurality of suture anchors being configured to be deployed from the shaft through a sidewall of the shaft, and each of the plurality of anchors being configured to be pulled proximally relative to the shaft to be deployed from the shaft through the sidewall of the shaft independent of a remainder of the anchors such that the anchors can be deployed sequentially from the shaft through the sidewall of the shaft, wherein each suture is configured to be pulled to deploy one of the plurality of suture anchors coupled thereto, wherein each suture extends through a suture channel formed in the shaft, and wherein a plurality of channels are formed in the elongate shaft each configured to seat one of the plurality of anchors, each of the plurality of channels having an open end and a closed end, where each of the plurality of channels are isolated from the suture channel. - View Dependent Claims (18, 19, 20, 21, 22)
