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.
Claims21
(canceled)
A delivery device comprising:
- an implant releasably located at a distal end of the delivery device;
- a heater configured to detach the implant when being activated;
- and
- a support coil configured to provide structural support to the delivery device, wherein the support coil is located at a proximal end of the heater, and wherein the support coil comprises a center region at a middle portion of the support coil, a distal region at a distal end of the support coil, and a proximal region at a proximal end of the support coil, wherein a coil density of the center region is higher than a coil density of the distal region and the proximal region.

A delivery device comprising:
- an implant releasably located at a distal end of the delivery device;
- a heater coil configured to detach the implant when being activated;
- a core wire comprising at least two radiopaque materials of different radiopaque values;
- and
- a support coil located between a proximal end of the heater coil and a distal end of the core wire, wherein the support coil comprises a first coil region and at least one second coil region, wherein a coil density of the first coil region is higher than a coil density of the second region.

A delivery device comprising:
- an implant releasably located at a distal end of the delivery device;
- a heater configured to detach the implant when being activated;
- and
- a support means configured to provide structural support to the delivery device, wherein the support means is located at a proximal end of the heater, and wherein the support means comprises a center region at a middle portion of the support coil, a distal region at a distal end of the support means, and a proximal region at a proximal end of the support means, wherein a coil density of the center region is higher than a coil density of the distal region and the proximal region.
