Abstract
Tissue expanders and methods of use. In some embodiments the tissue expanders are adapted to reduce wear on one or more components.
Claims44
A tissue expander comprising:
- an implantable portion comprising a fluid source in communication with an expandable chamber, wherein the expandable chamber includes an anterior portion, wherein the anterior portion includes a first deformable member and a second deformable member, wherein the first deformable member is disposed within the second deformable member, and the first deformable member has a thickness that is about 1.5 to about 8 times the thickness of the second deformable member.
A tissue expander comprising:
- an implantable portion comprising a fluid source in communication with an expandable chamber, wherein the expandable chamber includes an anterior portion, wherein the anterior portion includes a first deformable member and a second deformable member, wherein the first deformable member is disposed within the second deformable member, and the first deformable member has a thickness between about 75 microns and about 150 microns.
A tissue expander comprising:
- an implantable portion including
- an expandable chamber in fluid communication with a fluid source;
- a first deformable member at least partially defining the expandable chamber and having a pre-formed configuration;
- a second deformable member disposed about the first deformable member, wherein the second deformable member has a pre-formed configuration;
- and
- an outer elastic shell disposed about the first and second deformable members.
3 more elements
A tissue expander comprising:
- an implantable portion comprising a fluid source in fluid communication with an expandable chamber, a communication element secured to the expandable chamber and movable relative to the expandable chamber, wherein the communication element is disposed inside a pocket, and the pocket is attached to the expandable chamber, and wherein the communication element is secured inside the pocket such that it floats inside the pocket.
A tissue expander comprising:
- an implantable portion comprising a fluid source in fluid communication with an expandable chamber, a communication element secured to the expandable chamber and movable relative to the expandable chamber, wherein the communication element is disposed inside a pocket, and wherein the pocket is attached to the expandable chamber at a plurality of discrete locations with at least one unattached location where the pocket is not attached to the expandable chamber.
