Abstract
A device suitable for removing material from a living being is provided, featuring an infusate pump, and an aspiration pump, both powered by a motor. The aspiration pump and infusate pump preferably feature a helical pumping mechanism, and operate at a high rate of rotation, thereby ensuring adequate pumping performance and flexibility. Additionally, a narrow crossing profile is maintained, ensuring that the device may reach more tortuous regions of the vasculature.
Claims51
A flexible catheter system for clearing an accumulation of occlusive material from a vessel, duct or lumen in a living being, said flexible catheter system comprising a rotary helical aspiration pump, a rotary helical infusate pump, and a source of rotary power.
A flexible catheter system for clearing an accumulation of occlusive material from a vessel, duct or lumen in a living being, said flexible catheter system comprising a rotary helical aspiration pump, a reciprocating infusate pump and a source of rotary power.
A flexible catheter system for clearing an accumulation of occlusive material from a vessel, duct or lumen in a living being, said flexible catheter system comprising a driveshaft, a source of rotary power, a helical aspiration pump and a helical infusate pump;
- wherein said driveshaft is operatively connected to a source of rotary power and said driveshaft serves to actuate rotation for both:
- a. a helical aspiration pump serving to draw material in a proximal direction out of the living being, and;
- b. a helical infusate pump serving to deliver infusate fluid in a distal direction into the living being.
