Abstract
Abstract A penile implant provides a desirable erectness to the penis while at the same time permitting the penis to assume a flaccid position. The implant comprises an elongated rod formed of silicone rubber or other suitable material positionable within the corpus cavernosum of the penis. The rod has axially arrayed sections of various flexural properties. A proximal section suitable for positioning adjacent the pubis is medium stiff in flexure. A longer distal section located in the pendulus penis may be medium stiff or stiffer in flexure. The distal and proximal sections are separated by a very flexible hinge section.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
56 words
An elongated, rod-like, penile implant comprising, in a generally axial orientation: a relatively stiff proximal portion receivable in the crus of the corpus cavernosum for supporting the implant; a relatively stiff distal portion suitable for positioning, in the corpus cavernosum of the pendulus penis; and a relatively flexible hinge portion intermediate said proximal and distal portions.
Claim 2
Dependent Claim
56 words
An elongated, rod-like, penile implant comprising, in a generally axial orientation: a relatively stiff proximal portion receivable in the crus of the corpus cavernosum for supporting the implant; a relatively stiff distal portion suitable for positioning, in the corpus cavernosum of the pendulus penis; and a relatively flexible hinge portion intermediate said proximal and distal portions.
Claim 3
Dependent Claim
20 words
The implant according to claim 1 wherein the stiffness of the proximal portion and the distal portion are the same.
Claim 4
Dependent Claim
21 words
The implant according to claim 1 wherein the stiffness of the distal portion is greater than that of the proximal portion.
Claim 5
Dependent Claim
26 words
The implant according to claim 1 wherein the hardness of the material forming the proximal portion is approximately 55 as measured by a Shore A durometer.
Claim 6
Dependent Claim
21 words
The implant according to claim 4 wherein the material forming the proximal portion has a minimum tensile strength of 1000 psi.
Claim 7
Dependent Claim
26 words
The implant according to claim 1 wherein the hardness of the material forming the hinge portion is approximately 20 as measured by a Shore A durometer.
Claim 8
Dependent Claim
41 words
The implant according to claim 1 wherein the stiffness of said distal portion is such as to require a centrally applied force of between 225 and 430 grams to deflect said portion 3/16th inch when spanning a distance of 21/2 inches.
Claim 9
Dependent Claim
38 words
The implant according to claim 7 wherein the stiffness of said distal portion is such as to require a centrally applied force of 340 grams to deflect said portion 3/6th inch when spanding a distance of 21/2 inches.
Claim 10
Dependent Claim
21 words
The implant according to claim 1 wherein said distal portion comprises a relatively stiff core covered with a soft, flexible sheath.
Claim 11
Dependent Claim
31 words
The implant according to claim 9 wherein the hardness of the material forming said core of said distal portion is approximately 70 or more as measured by a Shore A durometer.
Claim 12
Dependent Claim
19 words
The implant according to claim 9 wherein said hinge portion is formed of the same material as said sheath.
Claim 13
Dependent Claim
18 words
The implant according to claim 11 wherein said hinge portion includes a central portion covered by said sheath.
Claim 14
Dependent Claim
15 words
The implant according to claim 12 wherein the portions of said implant are cemented together.
Claim 15
Dependent Claim
30 words
The implant according to claim 1 wherein a cord-like reinforcing means extends along the axis of said implant from said proximal portion through said hinge portion to said distal portion.
Claim 16
Dependent Claim
13 words
The implant according to claim 9 wherein said sheath includes a closed tip.
Claim 17
Dependent Claim
33 words
The implant according to claim 1 wherein said proximal portion includes a rod-like section having a diameter less than the remainder of the implant and a sloping portion joined to said hinge portion.
Claim 18
Dependent Claim
20 words
The implant according to claim 15 wherein the rod-like section of said proximal portion contains a plurality of circumferential grooves.
Claim 19
Dependent Claim
14 words
The implant according to claim 1 wherein said distal portion is of predetermined length.
Claim 20
Dependent Claim
33 words
The implant according to claim 1 wherein the length of said proximal portion is such as to permit trimming for altering the length of the implant to accommodate the anatomy of the patient.
Claim 21
Dependent Claim
12 words
The implant according to claim 1 wherein said portions are cemented together.
Claim 22
Dependent Claim
15 words
The implant according to claim 9 wherein the portions of said implant are cemented together.
Claim 23
Dependent Claim
16 words
