Abstract
A system for delivering an implant within a patient is disclosed. 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.
Claims20
A delivery device comprising:
- an elongated tubular member;
- an implant releasably connected to a distal end of the delivery device;
- a heater coil located at the distal end of the delivery device;
- a core wire at least partially fixed within the tubular member for providing support;
- a support coil located between a proximal end of the heater coil and a distal end of the core wire, the support coil comprising a first coil region having a first coil density and a second coil region have a second coil density, the second coil density being less than the first coil density;
- and
- a bare wire connected to and in electrical communication with the core wire at both a first location and a second location.
