Abstract

An implantable device system for controlling the dimensions of internal anatomic passages corrects physiologic dysfunctions resulting from a structural lumen which is either too large or too small. Implantable devices are disclosed which employ various mechanisms 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 dimensions of the implants after the resumption of normal flow of anatomic fluids in situ.

Claims

1. A device for positioning an adjustable implant device adjacent to target tissue, comprising:

An implant holding element configured to releasably hold said adjustable implant device;

A tool holding element configured to hold an adjustment tool and to allow operation thereof while so held, said adjustment tool being configured to adjust said adjustable implant device; and

An implant securing element having a configuration effective to secure said implant to said target tissue.

2. The system of claim 1, wherein said implant securing element has a first configuration adapted for penetrating tissue and a tip portion adapted for penetrating tissue and a second configuration adapted for engaging tissue.

3. A system for controlling the internal perimeter of an anatomic orifice or lumen disposed adjacent target tissue, comprising:

an adjustable implant device having an adjustable perimeter, a perimeter adjustment mechanism, and a docking element configures to operably engage an adjustment tool, said perimeter adjustment mechanism being operably connected with said docking element;

an adjustment tool configured to operably engage said docking element; and

an implant placement device comprising an implant engagement element and an implant securing element configured to secure said implant to said target tissue.

4. The system of claim 3 wherein said implant securing element comprises a tip portion configured to penetrate tissue, said implant securing element being configured to assume at least a first configuration and a second configuration, said first configuration being adapted for penetrating tissue, and said second configuration adapted for engaging tissue.
