Abstract:
1. A delivery device for an annular implant comprising: a balloon expansion mechanism, wherein the balloon expansion mechanism comprises a hollow catheter attached to an inflation tube whereby a gas or liquid is fed through said inflation tube and a non-occluding balloon collar attached to the inflation tube to provide for expansion of the balloon collar, wherein the balloon collar is supported by a plurality of trusses radially extending from the hollow catheter; an annular implant having an adjustable dimension removably mounted around the non-occluding balloon collar; a plurality of gunbarrel elements, wherein each gunbarrel element contains a hollow insert and a gunbarrel pusher and wherein the gunbarrel pusher drives an attachment element into the annular implant and annular tissue; a plurality of anchoring blocks attached to the annular implant, wherein each gunbarrel element is anchored into a corresponding anchoring block; a plurality of contiguous coiled spacers coiled along the annular implant, wherein each coiled spacer keeps each pair of anchoring blocks equidistant as the annular implant diameter is manipulated; a trocar releasably housing the gunbarrel elements; and a proximal control interface having control mechanisms for inflation of the balloon collar and deployment of the attachment elements.
