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 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;
- and,
- a support coil located between said distal end of said tubular member and said distal end of said core wire;
- wherein said distal end of said tubular member is primarily supported by said support coil.
5 more elements
A delivery device comprising:
- an elongated tubular member;
- an implant releasably connected to a 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 said distal end of said delivery device;
- wherein said delivery device has a higher flexibility at said support coil than at said core wire;
- wherein said distal end of said delivery device is primarily supported by said support coil.
5 more elements
A delivery device comprising:
- an elongated tubular member having a proximal region and a distal region between about 2 cm and about 4 cm from a distal end of said elongated tubular member;
- an implant retention mechanism located near said distal end of said elongated tubular member for selectively releasing an implant fixed to said distal end of said elongated tubular member;
- a core wire located solely within said proximal region of said elongated tubular member and terminating prior to said distal region of said elongated tubular member;
- and
- a support coil located in and primarily supporting said distal region of said elongated tubular member;
- wherein said distal region of said elongated tubular member has a greater flexibility than said proximal region of said elongated tubular member.
