Catheters for the removal of occlusions in a patient's vasculature. Exemplary catheters use a flexible distal end tube which is capable of coiling irregularly within the occlusion and securing it for removal.
Claims18
A catheter comprising:
- a tip;
- a polymeric flexible distal end tube comprising a substantially linear state and an irregularly coiled state;
- an inner mandrel;
- and
- an actuating mechanism.

A catheter comprising:
- a thrombus piercing tip;
- a flexible distal end tube comprising a substantially linear state and an irregularly coiled state;
- wherein the flexible distal end tube comprises irregularly corrugated, semi-porous ePTFE;
- an inner mandrel which provides structural support for the flexible distal end tube;
- and
- a guide wire.

A method for removing an occlusion from a human patient comprising:
- introducing a catheter into a patient's body, the catheter comprising a tip, a polymeric flexible distal end tube comprising a substantially linear state and an irregularly coiled state, an inner mandrel, and an actuating mechanism;
- piercing the occlusion with the tip of the catheter;
- withdrawing the inner mandrel from the polymeric flexible distal end tube;
- applying tension to the actuating mechanism, which converts the polymeric flexible distal end tube from the substantially linear state to the irregularly coiled state;
- withdrawing the catheter and occlusion from the patient's body.
