Apparatus for implanting surgical devices for controlling the internal circumference of an anatomic orifice or lumen
First Claim
1. A system for positioning an implantable device for an anatomic orifice or lumen, comprising:
- an implantable device with an adjustable member configured to adjust the dimensions of the implantable device, the implantable device having a surface that comes in direct contact with the anatomic orifice or lumen, said surface substantially defining a plane, the adjustable member being configured to be coupled to an adjustment tool that provides adjustment before, during or after the anatomic orifice or lumen resumes near-normal to normal physiologic function, the adjustment tool being positioned during adjustment in a non-planar orientation relative to the plane defined by said surface of the implantable device; and
an apparatus including;
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;
at least one deflection device configured to deflect 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; and
a device configured to hold the implantable device to the proximal ends of the arms.

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.
