Abstract
Abstract Apparatus for clearing lumens of thrombolytic material, comprising a motor including a control therefor operable using one hand holding the motor; an elongated wire connected to the motor for rotation by the motor; a catheter for enveloping a length of the wire; and a grip facilitating manual rotation of the catheter by the one hand independently of the wire as the wire is rotated by the motor at a speed sufficient to create a standing wave in a portion of the wire extending from the catheter.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
161 words
Apparatus for clearing lumens of thrombolytic material, comprising: a. a motor including control means therefor operable using one hand holding said motor; b. an elongated wire connected to said motor for rotation thereof by said motor; c. a catheter for enveloping a length of said wire; and d. gripping means facilitating manual rotation of said catheter by said one hand independently of said wire as said wire is rotated by said motor at a speed sufficient to create a standing wave in a portion of said wire extending from said catheter; e. first conduit means communicating with the interior of said catheter for selectably supplying or exhausting fluid to and from said catheter interior; f. a sheath enveloping said catheter; and g. second conduit means communicating with the interior of said sheath for selectably supplying or exhausting fluid to and from said sheath interior externally of said catheter, said second conduit means being movable longitudinally along said wire with said sheath.
Claim 2
Dependent Claim
161 words
Apparatus for clearing lumens of thrombolytic material, comprising: a. a motor including control means therefor operable using one hand holding said motor; b. an elongated wire connected to said motor for rotation thereof by said motor; c. a catheter for enveloping a length of said wire; and d. gripping means facilitating manual rotation of said catheter by said one hand independently of said wire as said wire is rotated by said motor at a speed sufficient to create a standing wave in a portion of said wire extending from said catheter; e. first conduit means communicating with the interior of said catheter for selectably supplying or exhausting fluid to and from said catheter interior; f. a sheath enveloping said catheter; and g. second conduit means communicating with the interior of said sheath for selectably supplying or exhausting fluid to and from said sheath interior externally of said catheter, said second conduit means being movable longitudinally along said wire with said sheath.
Claim 3
Dependent Claim
17 words
Apparatus of claim 1 further comprising manually actuable means for selectably connecting said wire to said motor.
Claim 4
Dependent Claim
28 words
Apparatus of claim 2 wherein said gripping means is fixedly connected to said first conduit means communicating with said catheter interior and rotatable unitarily therewith about said wire.
