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.

Abstract: An implantable medical lead and lead body, method of manufacturing the same, and a system and method for stimulating a portion of a body are disclosed. A lead body assembly is formed by preparing a first layer unitary body comprising a first plurality of conductors wound in a first direction. An inner layer of extrusion material is placed on the first layer unitary body. A second plurality of conductors coated with extrusion material is placed on the inner layer. The second plurality of conductors is wound in a second opposite direction. An outer layer of extrusion material is placed over the second plurality of conductors. Heat shrink tubing is placed over the assembly. The extrusion material is heated and melted and compressed around the conductors. When the heat shrink tubing is removed, the solidified extrusion material forms a protective wall that encapsulates the conductors in the lead body.

Abstract: An implantable lead and lead body, method of manufacturing the same, and a system and method for stimulating a portion of a body is disclosed. In one advantageous embodiment, a lead body assembly is formed by placing an inner layer of extrusion material on a mandrel, wrapping a plurality of conductors coated with extrusion material around the inner layer, and placing an outer layer of extrusion material over the plurality of conductors. Heat shrink tubing is placed over the lead body assembly and the lead body assembly is heated to melt the extrusion material. The melted extrusion material is compressed around the plurality of conductors. The assembly is then cooled and the heat shrink tubing is removed. The solidified extrusion material forms a protective wall that encapsulates the plurality of conductors in the lead body.
