Abstract

Abstract According to the invention, there is provided an implantable prosthetic device inflatable by a self-contained resealable valve in combination with an external locator for determining the position of the valve. The prosthesis includes a flexible outer envelope defining a closed lumen and having a valve attached to an area of the envelope with indicia on the valve responsive to the external locator for determining the position of the valve. A plurality of spaced sensors are each fixedly arrayed on the locator so that when the sensors are in a certain non-juxtaposed relationship with the indicia the sensors orientate with one another, signifying a true location of the valve. A multi-compartmental design having a tethered valve for selective inflation of an inner lumen is also disclosed. The tissue-contacting surface of the outer envelope is micro-textured to minimize tissue capsule contracture.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 79 words
An implantable prosthetic device inflatable by a self-contained resealable valve comprising: a outer flexible elastomeric envelope; an inner elastomeric envelope spaced inwardly from the outer envelope, respectively defining an outer closed lumen and an inner closed lumen nested within the outer lumen; a resealable injection valve attached to a selected area of the outer envelope, the inner envelope being tethered to the valve and spaced inwardly from the selected area by a fill-tube for directly inflating the inner lumen.
Claim 2
Dependent Claim 79 words
An implantable prosthetic device inflatable by a self-contained resealable valve comprising: a outer flexible elastomeric envelope; an inner elastomeric envelope spaced inwardly from the outer envelope, respectively defining an outer closed lumen and an inner closed lumen nested within the outer lumen; a resealable injection valve attached to a selected area of the outer envelope, the inner envelope being tethered to the valve and spaced inwardly from the selected area by a fill-tube for directly inflating the inner lumen.
Claim 3
Dependent Claim 76 words
An implantable prosthetic device inflatable by a self-contained resealable valve comprising: a first flexible elastomeric envelope; an second elastomeric envelope joined with the first envelope along a common surface, respectively defining first and second closed compartments; a resealable injection valve attached to a selected area of the first envelope, the second envelope being tethered to the valve through the first compartment and spaced from the selected area by a fill-tube for directly inflating the second compartment.
Claim 4
Dependent Claim 76 words
An implantable prosthetic device inflatable by a self-contained resealable valve comprising: a first flexible elastomeric envelope; an second elastomeric envelope joined with the first envelope along a common surface, respectively defining first and second closed compartments; a resealable injection valve attached to a selected area of the first envelope, the second envelope being tethered to the valve through the first compartment and spaced from the selected area by a fill-tube for directly inflating the second compartment.
