THROMBUS REMOVAL APPARATUS
First Claim
1. Thrombus removal apparatus including a catheter having a distal end, a proximal end and an internal lumen;
- a solenoid coil of conductive material located at or proximate the distal end of the catheter;
electrical couplings being connected to the coil; and
a piercing element disposed in the internal lumen at the distal end of the catheter;
the piercing element being movable in the catheter by application of electrical energy to the solenoid coil.

Abstract
A thrombus removal apparatus (10) includes a catheter (12) having at its distal end (14) a solenoid coil section (16) within which there is disposed a piercing element (20) made of electromagnetic material. Within the solenoid coil section (16) there is provided a solenoid coil (26) which can be powered to generate an electromagnetic field which causes the piercing element (20) to reciprocate into and out of the coil section (16), in practice to pierce into and fragment a thrombus disposed in a patient'"'"'s vessel. An aspiration unit may be provided for aspirating thrombus fragments into the assembly (10) for removal from the patient'"'"'s vasculature. The apparatus (10) is able to remove dense thrombus material from within a patient, which cannot be otherwise removed by means of thrombolytic agents.
