Endovascular tissue removal device
An endovascular tissue removal device including a lumen including a rotatable terminal hub advanceable in vasculature, at least one fiber extending from the hub for ablating tissue, and an expandable mechanism connected to the fiber for biasing it into position for precisely ablating tissue as the hub rotates.
1. An endovascular tissue removal device comprising:
a lumen including a rotatable terminal hub advanceable in vasculature;
at least one fiber extending from the hub for ablating tissue; and
an expandable mechanism including two balloons, one inside and one outside of the distal end of the fiber connected to the fiber for biasing it into position for precisely ablating tissue as the hub rotates.
2. An endovascular tissue removal device comprising:
a lumen including a rotatable terminal hub advanceable in vasculature;
at least one fiber extending from the hub for ablating tissue;
an expandable mechanism connected to the fiber for biasing it into position for precisely ablating tissue as the hub rotates; and
a tissue trap device surrounding the expandable mechanism.
3. An endovascular tissue removal device comprising:
a lumen including a rotatable terminal hub advanceable in vasculature;
at least one fiber extending from the hub for ablating tissue;
an expandable mechanism connected to the fiber for biasing it into position for precisely ablating tissue as the hub rotates; and
a mirror for redirecting the ablation energy.
4. An endovascular tissue removal device comprising:
a lumen including a rotatable terminal hub advanceable in vasculature;
at least one fiber extending from the hub for ablating tissue;
an expandable mechanism connected to the fiber for biasing it into position for precisely ablating tissue as the hub rotates; and
an expandable mechanism inflatable on the ventricular side of the valve for supporting the leaflets of the valve.
5. The device of claim 4 further including an absorptive surface on the expandable mechanism for absorbing ablation energy.
6. An endovascular valve removal device comprising:
a lumen including a rotatable terminal hub advanceable in vasculature;
at least one fiber extending from the hub for ablating valve tissue;
a first expandable mechanism connected to the fiber for biasing it into position for precisely ablating valve tissue as the hub rotates; and
a second expandable mechanism inflatable on the ventricular side of the valve for supporting the valve leaflets during resection.
