Abstract

The present disclosure relates to penile implants that are easier to implant and reduce trauma because they provide for a smaller effective width during implantation, after implantation, or both. The present disclosure also provides for a shorter tubing junction while reducing effective width, further reducing trauma to the body. In a first aspect, the penile implant includes a tubing junction that is smaller in effective diameter while implanted in the body. The penile implant includes an axially extending cylinder having an inflation chamber and a rear tip. The cylinder also includes a tubing junction disposed between the inflation chamber and rear tip and extending from the cylinder. The tubing junction includes a bore in fluid communication with the inflation chamber. In one example, this bore is in the strain relief of the tubing junction. The bore is configured to include a compound curve. In another aspect, the penile implant includes a tubing junction that can assume a smaller effective diameter while being implanted into the body. The surgeon is able to press the tubing against the cylinder than the related art to reduce the effective area of the penile implant. This penile implant includes a cylinder having an inflation chamber and a rear tip. A tubing junction is disposed between the inflation chamber and the rear tip. The tubing junction includes a strain relief that extends from the cylinder and forms an acute area proximate the intersection of the cylinder and the strain relief. The acute area includes a keyhole.

Claims

1. A penile implant, comprising:

a pair of cylinders each having an inflation chamber and a rear tip; and

a tubing junction disposed between the inflation chamber and rear tip and extending from each of the cylinders, the tubing junction having a bore in fluid communication with the inflation chamber;

a tubing disposed within the bore and in fluid communication with the inflation chamber;

wherein the bore is configured to include a curve having a compound angle, comprising more than one radius of curvature.

2. The penile implant of claim 1 wherein the tubing junction includes a strain relief.

3. The penile implant of claim 2 wherein the strain relief is adapted to receive the tubing.

4. The penile implant of claim 1 wherein the curve includes a path having two radii of curvature.

5. The penile implant of claim 1 wherein the curve includes a path having a transition region.

6. The penile implant of claim 1 wherein the tubing junction is in fluid communication with a pump.

7. The penile implant of claim 6 wherein the pump is in fluid communication with a fluid reservoir.

8. The penile implant of claim 2, wherein the strain relief is more rigid than the tubing.
