First Claim
Patent Images
1. A device for fallopian tube occlusion detection, comprising:
- a handle;
a catheter body longitudinally fixed relative to the handle, said catheter body having a distal end and a proximal end;
a rod longitudinally fixed relative to the handle;
a sheath slidably disposed about the rod, including a distal portion that is slidably extendable distally from the distal end of the catheter; and
a sheath retraction mechanism disposed within the handle, said sheath retraction mechanism comprisinga chassis fixedly coupled to the handle;
a sliding hub slidably engaged with the chassis and fixed to the sheath;
a fluid filled chamber;
a piston disposed within the chamber;
a piston rod coupled to the piston and the sliding hub; and
a spring operably engaged with the piston;
wherein the sheath retraction mechanism retracts the sheath when the spring is released, and said retraction is dampened by the fluid filled chamber.
