Abstract

An implantable device for controlling 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

Claims

1. An adjustable implantable device for an anatomic orifice or lumen, comprising:

an adjustable implant body configured to adjust an annular dimension of the implant body from a first shape to one of a range of a second shapes, the implant body configured to be attached to tissue adjacent the anatomic orifice or lumen; and

an adjustment tool configured to activate adjustment of the implant body;

wherein when the adjustment tool is removably coupled to an interface location of the implant body that receives the adjustment tool and initiates adjustment of the annular dimension of the implant body in situ.

2. The adjustable implantable device of claim 1, wherein the annular dimension can be adjusted to provide leaflet coaptation of an anatomic orifice.

3. The adjustable implantable device of claim 1, wherein the adjustable member is configured to non-uniformly adjust an annular dimension of the implant body.

4. The adjustable implantable device of claim 1, wherein said implant body further comprises a tube formed into an annular shape and wherein said implant body is attached to the tissue adjacent the anatomic orifice or lumen by securing said tube directly or indirectly to said tissue.

5. The adjustable implantable device of claim 1, wherein the said adjustment tool comprises a distal end and a proximal end, said distal end being removably coupled to said interface location and extending therefrom such that adjustments to the implant can be made from the proximal end.

6. The adjustable implantable device of claim 5, wherein said remote adjustments of the implant can be performed after resumption of physiologic flow in the annulus or lumen.

7. The adjustable implantable device of claim 5, wherein said adjustment tool provides direct circuitry to effect adjustment of the adjustable implant.

8. The adjustable implantable device of claim 5, wherein said adjustment tool provides electronic conduit leads to effect adjustment of the adjustable implant.

9. The adjustable implantable device of claim 1, wherein said adjustment tool provides electronic conduit leads to activate adjustment of the implant body.

10. The adjustable implantable device of claim 1, wherein said adjustable implant body comprises a synthetic material responsive to at least one of electric current and electromagnetic radiation.

11. An adjustable implantable device for an anatomic orifice or lumen, comprising:

an adjustable implant body configured to adjust an annular dimension of the implant body from a first shape to one of a range of a second shapes, the implant body configured to be attached to tissue adjacent the anatomic orifice or lumen; and

an adjustable member operatively communicating with said implant body to activate adjustment of the adjustable implant body in situ, wherein said adjustable member is responsive to exposure to electromagnetic radiation.

12. The adjustable implantable device of claim 11, wherein said exposure to electromagnetic radiation is achieved by delivery of said radiation to the implant from a source external to the patient.

13. The adjustable implantable device of claim 11, wherein said exposure to electromagnetic radiation is achieved by internal delivery of said radiation to the implant from an external radiation source.

14. The adjustable implantable device of claim 11, wherein the annular dimension can be adjusted to provide leaflet coaptation of an anatomic orifice.

15. The adjustable implantable device of claim 11, wherein the adjustable member is configured to non-uniformly adjust an annular dimension of the implant body.

16. The adjustable implantable device of claim 11, wherein said adjustable member is responsive to at least one of radio waves, microwaves, terahertz radiation, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

17. The adjustable implantable device of claim 11, wherein said adjustable member comprises a tube formed into an annular shape and wherein said implant body is attached to the tissue adjacent the anatomic orifice or lumen by securing said tube directly or indirectly to said tissue.

18. The adjustable implantable device of claim 11, wherein said adjustable member comprises a material responsive to electromagnetic radiation.

19. The adjustable implantable device of claim 11, wherein said exposure to electromagnetic radiation is initiated by a remote control.

20. A method for adjusting the internal dimension of an anatomic orifice or lumen, comprising the steps of:

introducing an adjustable implant device adjacent said anatomic orifice or lumen;

securing the adjustable implant device to tissue adjacent said anatomic orifice or lumen; and

remotely activating adjustment of a size or shape of said adjustable implant device using an external power source.

21. The method of claim 20, wherein said step of remotely activating adjustment of a size or shape of said adjustable implant device is initiated using remote control signals.

22. The method of claim 20, wherein said step of remotely activating adjustment of a size or shape of said adjustable implant device comprises use of electromagnetic radiation.

23. The method of claim 22, wherein said electromagnetic radiation is at least one of radio waves, microwaves, terahertz radiation, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

24. The method of claim 20, wherein said step of remotely activating adjustment of a size or shape of said adjustable implant device comprises use of direct circuitry.

25. The method of claim 24, wherein said direct circuitry comprises electronic conduit leads.

26. The method of claim 20, wherein further comprising the step of removably coupling an implant tool to an interface location on the implant device, said implant tool completing an electric circuit between said power source and said implant device.
