Apparatus for implanting surgical devices for controlling the internal circumference of an anatomic orifice or lumen
First Claim
1. An apparatus for positioning an annular implant about the perimeter of an anatomic orifice, comprising:
- a first shaft having proximal and distal ends;
a second shaft having proximal and distal ends and being slidably received within said first shaft;
a plurality of arms, each of said arms having a distal end deflectably mounted to said distal end of said second shaft;
means operatively associated with said first shaft for deflecting a proximal end of each of said plurality of arms away from said second shaft when relative movement between said first and second shafts is effected;
means for releasably holding an annular implant to said proximal ends of said arms; and
means detachably connectable to an annular implant for adjusting the circumference of said annular implant.

Abstract
A system for implanting a surgical device to control the circumference of internal anatomic passages corrects physiologic dysfunctions resulting from a structural lumen which is either too large or too small. Implants are disclosed which employ various means for adjusting and maintaining the size of an orifice to which they are attached. Systems permit the implants to be implanted using minimally invasive procedures and permit final adjustments to the circumference of the implants after the resumption of normal flow of anatomic fluids in situ. Methods are disclosed for using the implants to treat heart valve abnormalities, gastroesophageal abnormalities, anal incontinence, and the like.
