Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
111 words
A mammary prosthesis for subcutaneous implantation comprising: a flexible body designed to extend in length substantially from the posterior of the breast to the anterior thereof and having a transverse cross-section corresponding in shape to a section or quadrant of the breast; the body defining, in transverse cross-section, a wedge shape comprising at least three sides, including two substantially straight supporting inner sides for anchoring the body to adjacent breast tissue and for conforming the shape of the body to the breast, and a curved outer side corresponding to the contour of the breast, and wherein the body comprises a seamless silicone envelope which is filled with a cohesive silicone gel.
Claim 2
Dependent Claim
111 words
A mammary prosthesis for subcutaneous implantation comprising: a flexible body designed to extend in length substantially from the posterior of the breast to the anterior thereof and having a transverse cross-section corresponding in shape to a section or quadrant of the breast; the body defining, in transverse cross-section, a wedge shape comprising at least three sides, including two substantially straight supporting inner sides for anchoring the body to adjacent breast tissue and for conforming the shape of the body to the breast, and a curved outer side corresponding to the contour of the breast, and wherein the body comprises a seamless silicone envelope which is filled with a cohesive silicone gel.
Claim 3
Dependent Claim
120 words
A reconstructive mammary soft tissue replacement prosthesis comprising: a seamless silicone envelope designed to extend in length substantially from the posterior of the breast to the anterior thereof and having a transverse cross-section corresponding to a generally wedge shaped transverse section of the breast and being filled with a cohesive silicone gel and covered with a thin microfiber polyurethane layer; the transverse cross-section of the envelope comprising at least three sides, including two substantially straight inner sides for anchoring the envelope to adjoining breast tissue and for conforming the envelope to the shape of the breast, and a curved outer side corresponding to the outer contour of the breast; and means for anchoring the envelope to the adjoining breast tissue.
