Abstract
Abstract An implant useful for the surgical construction of a penis comprises an elongated member having a pair of stems at the proximal end for anchoring the member in the pubic area of a patient, and a trunk with a urethra receiving and supporting groove and an open distal end. In the preferred embodiment, the implant is made completely of silicone elastomer. A method of constructing a penis using the implant is also described.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
66 words
An implant for the construction or reconstruction of a penis, said implant consisting of a body member of biocompatible material having an elongated relatively rigid trunk with a urethra receiving groove extending longitudinally down the center thereof, one end of said trunk has a rounded tip and the other end of the trunk is connected by a flexible hinge to a pair of anchoring trimmable stems.
Claim 2
Dependent Claim
66 words
An implant for the construction or reconstruction of a penis, said implant consisting of a body member of biocompatible material having an elongated relatively rigid trunk with a urethra receiving groove extending longitudinally down the center thereof, one end of said trunk has a rounded tip and the other end of the trunk is connected by a flexible hinge to a pair of anchoring trimmable stems.
Claim 3
Dependent Claim
24 words
The implant of claim 1 in which the trunk is provided with means through which tissue can grow to provide vascularization of the urethra.
Claim 4
Dependent Claim
17 words
The implant of claim 1 which includes means for the ingrowth of tissue to anchor the implant.
Claim 5
Dependent Claim
105 words
The method of constructing a penis which comprises: (a) anchoring an implant of claim 1 in the pubic area of a patient by use of the stems; (b) making an urethra by forming a tube from the first flap of a patient's skin with the skin side in; (c) operatively connecting one end of the thus formed urethra to the urinary tract of the patient; (d) positioning the urethra in the urethra receiving groove of the trunk of the implant; and (e) covering the implant and the urethra with a second flap of relatively thicker skin with the raw side in to form a penis.
