Abstract

Implantable apparatuses and method of implanting the apparatuses are disclosed that provide a person with a neopenis including a penile prosthetic implanted into a neophallus. The neopenis is situated anatomically in a position of that of a location for a penis of a natal male. The neopenis is suitable for penetrative intercourse.

First claim

What is claimed is:

1. A neophallus implant comprising:
a distal portion that is adapted for insertion into tissue of a neophallus to provide the neophallus with an erection adapted for penetrative intercourse;
a first proximal portion and a separate second proximal portion; and
a transfer joint having a distal end connected to the distal portion of the neophallus implant, a first proximal end connected to the first proximal portion of the neophallus implant, a second proximal end connected to the separate second proximal portion of the neophallus implant, with a body of the transfer joint extending between the distal end, the first proximal end, and the second proximal end;
wherein the body of the transfer joint has a fixed bend that is adapted to orient the first proximal portion and the separate second proximal portion alongside a descending pubic ramus on either side of a pubic arch of a trans-male pelvis.

2. The neophallus implant of claim 1 , wherein at least the distal portion of the neophallus implant is an inflatable penile prosthetic.

3. The neophallus implant of claim 1 , further comprising a liquid port connected to one of the first proximal portion and the second proximal portion.

4. The neophallus implant of claim 1 , wherein the distal portion of the neophallus implant is an inflatable penile prosthetic and the first proximal portion and the second proximal portion of the neophallus implant are not inflatable.

5. The neophallus implant of claim 1 , wherein the distal portion of the neophallus implant is an inflatable penile prosthetic having one and only one inflatable cavity.

6. The neophallus implant of claim 1 , wherein a diameter of the distal portion of the neophallus implant is larger than a diameter of the first proximal portion and a diameter of the second proximal portion.

7. The neophallus implant of claim 1 , wherein the distal portion is an inflatable penile prosthetic having a first inflatable cavity coupled along a septum to a second inflatable cavity.

8. The neophallus implant of claim 1 , wherein the neophallus implant is monolithically formed as a single unit to include the transfer joint, the distal portion, the first proximal portion of the neophallus implant, and the second proximal portion of the neophallus implant.

9. The neophallus implant of claim 1 , wherein the fixed bend in the transfer joint orients the first proximal portion of the neophallus implant at an angle in a range from 80-110 degrees relative to the second proximal portion of the neophallus implant to adapt the first proximal portion and the second proximal portion of the neophallus implant to align with a female pubic arch.

10. The neophallus implant of claim 1 , wherein the first proximal portion and the second proximal portion of the neophallus implant have a flat profile with a rectangular cross-sectional shape.

11. The neophallus implant of claim 1 , wherein the first proximal portion and the second proximal portion are each a solid component having a circular lateral cross-sectional shape that tapers to converge to a proximal end.

12. The neophallus implant of claim 1 , wherein the transfer joint, the distal portion, the first proximal portion, and the second proximal portion combine to provide a Y-shaped neophallus implant.

13. A method of implanting a penile prosthetic in a neopenis, the method comprising:
providing a neophallus implant having a transfer joint connected between a distal portion and a first proximal portion, with the transfer joint having an angle that maintains the distal portion off of a longitudinal axis of the first proximal portion;
forming a neophallus;
inserting the distal portion into the neophallus and forming a neopenis; and
securing the first proximal portion of the neophallus implant between muscle attached to a ramus of a trans-male pelvis and tissue.

14. The method of claim 13 , further comprising:
implanting a pump and a reservoir;
coupling the pump and the reservoir to the distal portion of the neophallus implant; and
inflating the distal portion of the neophallus implant to provide the neopenis with an erection.

15. The method of claim 13 , comprising forming a tissue pocket alongside of the ramus and securing the first proximal portion of the neophallus implant in the tissue pocket between the muscle attached to the ramus of the trans-male pelvis and subcutaneous tissue.

16. A method of implanting a penile prosthetic in a neopenis, the method comprising: providing a neophallus implant having a transfer joint connected to an inflatable distal portion, a first proximal portion, and a second proximal portion such that the neophallus implant is a Y-shaped inflatable implant;
forming a neophallus; inserting the inflatable distal portion into the neophallus;
retaining the first proximal portion of the Y-shaped inflatable implant between muscle attached to a first ramus of a trans-male pelvis and first tissue superior to the muscle attached to the first ramus;
retaining the second proximal portion of the Y-shaped inflatable implant between muscle attached to a second ramus of the trans-male pelvis and second tissue superior to the muscle attached to the second ramus; and
engaging a fixed bend in the transfer joint with at least one of the first tissue and the second tissue and constraining movement of the Y-shaped inflatable implant.

17. The method of claim 16 , further comprising:
forming a first tissue pocket between the muscle attached to the first ramus of the trans-male pelvis and the first tissue superior to the muscle; and
forming a second tissue pocket between the muscle attached to the second ramus of the trans-male pelvis and the second tissue superior to the muscle.

18. The method of claim 17 , further comprising:
maintaining an opening of the first tissue pocket and maintaining an opening of the second tissue pocket by inserting a place holder into each of the first tissue pocket and the second tissue pocket.

19. The method of claim 16 , further comprising:
providing the neophallus implant with a flat first proximal portion and a flat second proximal portion;
placing the flat first proximal portion over the muscle attached to the first ramus; and
placing the flat second proximal portion over the muscle attached to the second ramus.

20. The method of claim 16 , further comprising:
forming the fixed bend in the transfer joint at a pubic arch angle to align the first proximal portion of Y-shaped inflatable implant and the second proximal portion of Y-shaped inflatable implant with a pubic arch of the trans-male pelvis.
