Implantable devices for controlling the internal circumference of an anatomic orifice or lumen
First Claim
1. An adjustable implantable device for adjusting the dimensions of an anatomic orifice or lumen in a mammalian body, comprising:
- an adjustable prosthetic implant device configured to have an annular dimension adjustable from a first dimension to one of a range of second dimensions, the prosthetic implant device having a rotatable adjustable member configured to be releasably attached to an adjustment tool, the adjustable member including a first gear having a first rotational axis and a second gear having a second rotational axis engaged with the first gear, wherein the first rotational axis traverses the second rotational axis, the prosthetic implant device configured to be attached to tissue within a mammalian body adjacent the anatomic orifice or lumen; and
an adjustment tool configured to activate rotation of the first and second gears of the adjustable member upon attachment to the second gear for adjustment of the prosthetic implant device from the first dimension to one of the range of second dimensions;
the adjustment tool being operative to initiate adjustment of the annular dimension of the prosthetic implant device over the range from the first dimension to the second dimensions in situ by rotation of the adjustable member; and
wherein the adjustment tool is detachable from the second gear of the prosthetic implant device after adjustment thereof and is withdrawable from within the mammalian body.

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.

13. An adjustable implantable device for an anatomic orifice or lumen in a mammalian body comprising:
-
an implantable implant body comprising a prosthetic implant device having a rotatable adjustable member operative to adjust the annular dimension or shape of the implant body over a functional range when attached to an adjustment tool, the adjustable member including a first gear having a first rotational axis and a second gear having a second rotational axis engaged with the first gear, wherein the first rotational axis traverses the second rotational axis, the implant body configured to be attached to tissue within a mammalian body adjacent the anatomic orifice or lumen; and an adjustment tool having a proximal end and a distal end, the distal end configured to be releasably attached to the adjustable member for rotation of the first and second gears when received intracorporeal of the mammalian body with the proximal end arranged extracorporeal of the mammalian body; wherein the distal end of the adjustment tool is remotely operative when attached to the adjustable member to initiate adjustment of the implant body by rotation of the adjustable member, in situ, over the functional range while the proximal end of the adjustment tool is arranged extracorporeal. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. An adjustable implantable device for an anatomic orifice or lumen in a mammalian body, comprising:
-
an adjustable implant body having an adjustable annular dimension, the implant body including a rotatable adjustable member adapted to adjust the annular dimension of the implant body from a first dimension to one of a range of second dimensions upon rotation when attached to an adjustment tool, the adjustable member including a first gear having a first rotational axis and a second gear having a second rotational axis engaged with the first gear, wherein the first rotational axis traverses the second rotational axis, the implant body configured to be attached to tissue within a mammalian body adjacent the anatomic orifice or lumen; and an adjustment tool configured to activate adjustment of the implant body from the first dimension to one of the range of second dimensions by rotation of the first and second gears of the adjustable member, the adjustment tool having an end configured for releasable attachment to the adjustment member; wherein, when the adjustment tool is attached within a mammalian body to the adjustable member of the implant body, the adjustment tool being operative by rotation thereof to initiate adjustment of the annular dimension of the implant body over the range from the first dimension to the second dimensions in situ; and wherein the adjustment tool is detachable from the adjustable member after adjustment of the implant body in situ and is withdrawable from within the mammalian body. - View Dependent Claims (22)
