  • Patent number: 10835278
    Abstract: Thrombectomy catheter systems, accessory devices, and methods for making and using such devices are disclosed. An example thrombectomy system may include a catheter shaft having a proximal portion, a distal portion, and a lumen extending at least partially through the catheter shaft. A high pressure tube may be disposed within the lumen. The high pressure tube may be designed for communication with a fluid source. A fluid jet emanator may be coupled to the high pressure tube. The fluid jet emanator may have at least one jet orifice. The catheter shaft may include a first orifice disposed proximally of a distal end of the catheter shaft and a second orifice disposed proximally of the first orifice. An accessory device may be disposed within the lumen. The accessory device may include a helical distal region.

  • Patent number: 7879022
    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.

  • Patent number: 7608063
    Abstract: A dual lumen aspiration catheter system with an aspiration catheter, a hub and a flexible strain relief, and a suction assembly. The aspiration catheter includes multiple successively connected flexible tubular components each increasing in relative flexibility in the distal direction, the most proximal tubular component connectingly extending from the hub and through the flexible strain relief. The tubular components of the aspiration catheter include, in order proximally to distally, a composite tube, an intermediate tube, a dual lumen tube, and a flexible tip tube. The dual lumen tube includes eccentrically co-located large and small tubular portions forming eccentrically co-located large and small lumens to provide a minimum cross section. The distal end of the dual lumen tube includes a convex beveled edge. The convex beveled edge and the flexible tip tube singly or jointly inflict minimal traumatic contact with a vessel wall when urged along a tortuous vascular path.

  • Publication number: 20080300532
    Abstract: An enhanced cross stream mechanical thrombectomy catheter with backloading manifold having a distal end with outflow and inflow orifices at one side for producing concentrated cross stream jet flow for selective and concentrated thrombus ablation during thrombectomy procedures. The invention provides for suitable distancing of high powered ablation or suction forces from the near walls of the vasculature. Cross stream flow emanating from the one side of the distal end of the catheter resultantly urges the distal end of the catheter and thus the opposing non-orificed side of the distal end of the catheter toward and against the vascular wall to inhibit contact of the inflow orifice with the vascular wall. Features of the invention include a geometrically configured insert to facilitate the backloading or exchange of guidewires.
