Abstract
A system for delivering an implant within a patient is described. The activation of the heater coil causes the degradation, melting or reduction of a component that brings the heater coil into or out of electrical contact with another component, or causes the individual loops of the coil to contact each other, thereby resulting a notable change in resistance in the circuit supplying the heater coil with electricity. A core wire terminates prior to the distal end of the device, allowing for greater flexibility.
Claims16
A delivery device comprising:
- an elongated tubular member;
- an implant retention mechanism located within said tubular member and releasably securing an implant at a distal end of said tubular member;
- a core wire for strengthening said elongated tubular member;
- said core wire at least partially located within said tubular member;
- said core wire having a distal end terminating between about 2 cm and about 4 cm from said distal end of said tubular member;
- a support coil located between a proximal end of a heater coil and a distal end of said core wire;
- a non-insulated wire electrically connected to said core wire at a first and second location, and further connected to said heater coil.
A delivery device comprising:
- an elongated tubular member;
- an implant releasably connected to a distal end of said delivery device;
- a heater coil located at said distal end of said delivery device;
- a core wire at least partially fixed within said tubular member for providing support;
- said core wire having a distal end terminating between about 2 cm and 4 cm from said distal end of said delivery device;
- and,
- a support coil located between said distal end of said core wire and a proximal end of said heater coil;
- a bare wire connected to and in electrical communication with said core wire at both a first location and at a second location;
- said bare wire further connected to and in electrical communication with said heater coil.
A delivery device comprising:
- an implant retention mechanism located near a distal end of said delivery device for selectively releasing an implant;
- a core wire at least partially located within an elongated tubular member of said delivery device for providing resistance to bending;
- said core wire having a distal end terminating between about 2 cm and 4 cm from said distal end of said delivery device;
- and,
- a support coil connected to a distal end of said core wire and extending to said distal end of said distal end of said delivery device;
- an insulated wire and a bare wire arranged to selectively supply electricity to a heater coil of said implant retention mechanism;
- wherein said bare wire is electrically connected to said core wire at a first and second location.
