A variable detachment embolic coil system and guidewire system are also described.
Claims20
A steerable catheter system comprising:
- a catheter comprising one or more electrical contacts configured to supply from a power supply;
- a guidewire movable within said catheter;
- wherein supplying power to said one or more electrical contacts causes said guidewire to bend.
A steerable catheter system, comprising:
- a guidewire having an elongate shape and being sized to move through a catheter;
- said guidewire having a first cross sectional portion composed of a first metal and a second cross sectional portion composed of a second metal, such that when heated, said guidewire bends.
A method of steering a catheter comprising:
- advancing a guidewire through a lumen of a catheter;
- said lumen having one or more electrical contacts exposed within said lumen;
- contacting said one or more electrical contacts with said guidewire;
- directing power to said one or more electrical contacts so as to increase a temperature of said guidewire, thereby causing a distal end of said guidewire to bend;
- and,
- orienting said distal end of said guidewire in a desired direction.
