Abstract
Disclosed are implantable tissue augmentation devices, methods, and associated tools. The devices include an inflatable body, having an inner layer and an outer layer. A valve is provided for permitting the introduction of and retaining inflation media. At least one pull tab is provided on an end of the implant, to assist in positioning the implant. Kits and systems are also disclosed.
Claims133
An implantable tissue augmentation device, comprising:
- an elongate, flexible tubular body, having a proximal end, a distal end and a cavity;
- a valved opening on the proximal end;
- a closed distal end;
- a first, inner layer for retaining inflation media within the implant, and a second, outer microporous layer for enabling tissue ingrowth;
- and
- at least one grasping means to allow positioning of the device at a desired site, wherein the grasping means comprises at least one tab.

An implantable tissue augmentation device for treating facial wrinkles, comprising:
- an elongate, flexible tubular body, having a proximal end, a distal end and a cavity, wherein the tubular body has a first cross-section and a second cross-section;
- the first cross-section having a cross-sectional area that is at least 110% of the second cross-section;
- a valved opening on the proximal end;
- a closed distal end;
- a first configuration and a second configuration, wherein said tissue augmentation device is transformable from the first configuration to the second configuration by introduction of a filler into the cavity via the valved opening;
- and
- an inner layer and an outer layer, wherein the outer layer comprises a porous material to encourage fibrous ingrowth and wherein the inner layer comprises an elastomeric material that adds flexibility to the body and is for contact with the filler material, wherein the inner and outer layers are bonded together.
