1. A method of securing a device to bodily tissue comprising:
- providing a device having associated tissue attaching fasteners, wherein the device comprises a housing that comprises a plurality of the tissue attaching fasteners pivotally mounted thereto and acted on by a rotating disc in the device to displace each fastener from a first position above a lower surface of the device to a second position below the lower surface;
positioning the lower surface of the device on the bodily tissue;
covering the device with a delivery system;
activating the delivery system to rotate the disc such that the attaching fasteners are each pivotally rotated from the first position to the second position to secure the device in bodily tissue; and
,removing the delivery system from the secured device.

Abstract
A surgical fastening system for implantable devices is disclosed. The implantable device may contain a plurality of fasteners in pre-deployment position, may have a housing fitted over or around it which contains a plurality of fasteners in pre-deployment position, or may be a part of a two-part system into which it fits. Accordingly, the present invention also encompasses a deployment system or tool that optionally positions the implantable device, and which causes the fasteners to move into post-deployment position. The fasteners may be staples, metal loops, coils, springs or hooks formed of biocompatible materials, including shape memory alloys such as NiTi.

19. A method of securing a device to bodily tissue comprising:
-
providing a device having associated tissue attaching fasteners, wherein the device comprises a housing that comprises a plurality of the tissue attaching fasteners pivotally mounted thereto and acted on by a rotating disc in the device to displace each fastener from a first position above a lower surface of the device to a second position below the lower surface, wherein each fastener has a sharp tip for piercing tissue, and wherein in the first position the sharp tips of the fasteners are located above a bottom surface of the housing and in the second position the fasteners rotate so that the sharp tips pass through tissue below the housing and nest against the bottom surface of the housing; positioning the lower surface of the device on the bodily tissue; covering the device with a delivery system; activating the delivery system to rotate the disc such that the attaching fasteners are each pivotally rotated from the first position to the second position to secure the device in bodily tissue; and
,removing the delivery system from the secured device. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
