Definitions

  • TECHNICAL FIELD A penile rigidity prosthesis which is adapted to be surgically implanted into the corpus cavernosum of the penis in men for the treatment of erectile impotence.
  • the present invention relates to a novel implantable penile rigidity prosthesis, More particularly it relates to a double silicone sheet and metal wires core which makes it more maleable and less harder and also resitant to rupture achieving the desirable longitudinal rigidity of the penis for vaginal intromission.
  • a variable size type is also provided.
  • Figure 1 is a side section view along the midline of the entire penile rigidity prosthesis,in one preferred embodiment, the fixed lenght model.
  • Figure 2 is a enlarged cross sectional view taken along the midportion of the implant.
  • Figure 3 is a tridi ensional and a cross sectional view of the proximal end or the prosthesis tail.
  • Figure 4 is a tridimensional and a cross sectional view of the distal end or the prosthesis tip.
  • Figure 5 is a side view of one penile rigidity prosthesis in one preferred embodiment of the variable size model. Left : the main body with its rounded front tip , the metal wires fixed into the screw .
  • Middle a spare cylinder extension with its screw and inside and outside threads.
  • Right the tail of the prosthesis with its single inner thread screw.
  • Figure 6 is a tridimensional and cross sectional view of parts of the variable size prosthesis.
  • Middle a spare cylinder extension.
  • Right the tail and its screw.
  • the penile rigidity prosthesis consists of two identical and independent rods that can be surgically implanted completely into the penis through the most usual surgical techniques.
  • Each rod has a cylindrical body with a round tip and a quasi-conical tail.
  • the external wall of the cylinder is made of elastic harder material, preferentially medical grade silicone with a ir nimum hardness of 60 shore A and a elongation capability of at least 700% .
  • the core is made of metal wires occupying about 60% of the total lenght of the implant. Between the core and the external wall there are sheets of softer material with a hardness of approximately 20 shore A and ' a smaller elongation capability.
  • the metal core extremities attaches into a screw; its thread determines the border of the implant main body.
  • the tail also has a screw with a internal thread that matches the screw of the main body.
  • the implant has an inteimediate cylinder portion, a rounded tip and a quasi-conical tail.
  • the inner portion of the prosthesis core is made of twisted metal wires (3) .
  • Its outer shelf (1) is made of harder elastic material, preferably medical grade silicone rubber, having a hardness around 60 shore A and at least 700% of elongation. Between the metal core and the outer shelf there sheets of softer material, preferably medical grade silicone rubber with a hardness between 20 and 40 shore A. The elongation of this material should be greater than 350% .
  • the size of the central metal core should be 60% of the total prosthesis lenght being nearer the tip than the tail (figures 3 and 4) .
  • the metal wire core can be made of any maleable metal wire, according its biocompatibility, being the wires thinner as the metal becomes less maleable.
  • the metal wires shall be twisted all together.
  • the thickness of the harder outer shell shall be kept between 1.5 and 2.3 mm.
  • the central metal core ends into a screw with its thread (10) off the main body of the prosthesis.
  • a cylinder spare extension with a screw having an inner thread at one side and an outer thread at the other (9) is covered (6) with the same sheet of hard material as the main body and has the same final thickness and outer diameter.
  • the tail has also an inner thread (Figure 6., 11),that matches either the main body or the cylinder extension , and desirably a quasi-conical shape with the same materials employed on the main body.
  • the double sheet prosthesis described in this application reduces this trouble to zero due to its greater elasticity and the reinforced external wall . Furthermore the remoteness of the metal wire core from the extremities let them softer and more capable of receiving stresses or pressure specially during sexual intercourse. Finally, due to its double sheet material build up the total back up force of the elastic material is reduced allowing a efficient bending of the metal core which angles further than 90° leaving the penis at its natural hang on position along the plane of the body.
  • variable size is fitted. If yhe size of the implant is determined by external conventional measurements - the size of the distended penis from the midglans to the pubic bone, plus seven centimenters (expectation on the lenght of the inner region of the corpus cavernosum) - it is recommended a kit consisting of main body , two spare extensions and a tail - which mounted all together fits that expectation - supplied with one additional spare extension. If in the surgery room an underestimation is revealed another extension may be added. If occurs an overestimation up .to two spare-cylinders can be removed with no compromise on the anatomy of the implant " .
