Abstract
A rapid exchange fluid jet thrombectomy device having a streamlined manifold and a catheter having multiple tubular segments where each tubular segment increases in flexibility in a distal direction. Torque response and pushability is enhanced by the arrangement of a proximally located tubular segment composed of a polymer-jacketed spiral metal tube in combination with an intermediate tubular section and a distal tubular section each having different degrees of flexibility. A guidewire tube exit region is provided where the intermediate tubular section joins the distal tubular section for over-the-wire guidewire usage. The polymer-jacketed spiral metal tube can extend along a partial or full length of the catheter and can include a basic continuous spiral cut which has regions of constant pitch or which has progressively increasing pitch, or in the alternative, can include an interlocking spiral cut having constant pitch regions or progressively decreasing pitch.
