Abstract
A catheter with one or more heated or detachable sections is described. The catheter may be useful for liquid embolic delivery, where the heated or detachable sections may help free the catheter when stuck to liquid embolic during delivery. An instrumented catheter is also described.
Claims21
A detachable tip catheter comprising:
- a proximal catheter section;
- a distal detachable tip catheter section adjacent the proximal catheter section;
- a detachment mechanism connecting the proximal catheter section with the distal detachable tip catheter section;
- the detachment mechanism comprising one or more pins engaged with a retention structure;
- and,
- electrical wires configured to supply electrical current to the detachment mechanism;
- wherein the retention structure moves, without melting, from a first position in which the one or more pins are physically engaged, to a second position in which the one or more pins are disengaged when electrical current is supplied to the detachment mechanism.
4 more elements
A catheter comprising:
- a proximal catheter portion;
- a distal tip portion;
- and,
- a detachment joint releasably connecting the proximal catheter portion with the distal tip portion;
- the detachment joint comprising a plurality of pins engaged with a retention structure;
- wherein the retention structure is configured to move, without melting, from a first position engaging the plurality of pins to a second position releasing engagement of the plurality of pins when electrical current is supplied from the proximal catheter portion to the detachment joint.
3 more elements
A catheter comprising:
- a proximal catheter portion;
- a distal tip portion located at a distal end of the proximal catheter portion;
- and,
- a detachment mechanism engaging the proximal catheter portion with the distal tip portion;
- the detachment portion comprising a plurality of pins engaged with a retention structure;
- wherein the retention structure is configured to move, without melting, from a first position engaging the plurality of pins to a second position releasing engagement of the plurality of pins when electrical current is supplied from the proximal catheter portion to the detachment mechanism.
