Abstract
An intraurethral contraceptive device includes an insertion tool and a urethral sleeve inside the insertion tool. The urethral sleeve includes a balloon on an outer surface and a distal proximal end of the urethral sleeve, having an air lumen that extends to a distal end of the urethral sleeve. There is an inside reservoir at a distal end of the sleeve, configured to capture any fluid traveling from the proximal end to the distal end of the urethral sleeve. An insertion plunger is coupled to a plunger head. The insertion plunger is configured to be placed inside a distal end of the insertion tool.
Claims25
An intraurethral contraceptive device, comprising:
- an insertion tool;
- a urethral sleeve inside the insertion tool, the urethral sleeve comprising:
- a balloon on an outer surface at a proximal end of the urethral sleeve, having an air lumen that extends to a distal end of the urethral sleeve filled with an expandable gas;
- a seal at the distal end of the air lumen;
- a gas capsule in communication with the air lumen filled with a gas that reacts with the expandable gas in the air lumen so that when the gas capsule is broken, the gas from the capsule reacts with the expandable gas from the air lumen to inflate the balloon;
- and
- an inside reservoir at a distal end of the sleeve, configured to capture any fluid traveling from the proximal end to the distal end of the urethral sleeve;
- and
- an insertion plunger coupled to a plunger head, wherein the insertion plunger is configured to be placed inside a distal end of the insertion tool.
A method of collecting a sperm sample from a mammal using an intraurethral contraceptive device having an insertion tool, a urethral sleeve inside the insertion tool, and an insertion plunger at a distal end of the insertion tool, the method comprising:
- slidingly inserting the insertion tool into a urethra;
- releasing a proximal portion of the urethral sleeve from a proximal end of the insertion tool into the urethra, the urethral sleeve having a balloon and a one-way valve located at the proximal end that allows fluid to flow into the urethral sleeve;
- slidingly removing the insertion tool together with the insertion plunger from the urethra;
- leaving the urethral sleeve internalized within the fossa navicularis catching any fluid traveling from the proximal end to the distal end of the urethral sleeve by a reservoir coupled to a distal end of the urethral sleeve;
- deflating the balloon;
- and
- removing the urethral sleeve from the urethra.
An intraurethral contraceptive device, comprising:
- an insertion tool;
- a urethral sleeve inside the insertion tool, the urethral sleeve comprising:
- a balloon on an outer surface at proximal end of the urethral sleeve, having an air lumen that extends to a distal end of the urethral sleeve;
- an inside reservoir at a distal end of the sleeve, configured to capture any fluid traveling from the proximal end to the distal end of the urethral sleeve;
- a one-way valve at the proximal end of the urethral sleeve configured to prevent fluid from exiting the urethral sleeve;
- and
- an insertion plunger coupled to a plunger head, wherein the insertion plunger is configured to be placed inside a distal end of the insertion tool.
An intraurethral contraceptive device, comprising:
- an insertion tool;
- a urethral sleeve inside the insertion tool, the urethral sleeve comprising:
- a sleeve retainer on an outer surface of the urethral sleeve;
- and
- an inside reservoir at a distal end of the sleeve, configured to capture any fluid traveling from the proximal end to the distal end of the urethral sleeve;
- and
- an insertion plunger coupled to a plunger head, wherein the insertion plunger is configured to be placed inside a distal end of the insertion tool.
