A catheter includes a catheter body with a compliant balloon secured at a distal end of the catheter body, the balloon including a proximal end and a distal end, a first lumen in fluid communication with the balloon, a second lumen in fluid communication with at least one infusion aperture directly adjacent the proximal end of the balloon, and a third lumen in fluid communication with a port positioned distally of the balloon. A method for using the catheter is also provided.

An apparatus for performing a vascular treatment includes an intraluminal member that is controllingly moved during the vascular treatment. The intraluminal member of the vascular treatment device can be connected to a motor. The rotation direction of the intraluminal member can be reversed to reduce the incidence and duration of vein entanglement during a vascular ablation procedure. Reversal of direction could occur automatically, or in response to a sensor such as a load sensor provided as part of the motorized drive system.

An access system for providing subcutaneous access to a vessel, organ, or body cavity comprises a needle and a rigid or semi-rigid tunneler arranged coaxially around the needle, such that the needle moves slidably within the tunneler. Optionally a sheath may be positioned coaxial to the tunneler. The tunneler-needle system is inserted through an incision in a patient's skin to initiate a procedure whereby a catheter is inserted into the vessel, organ, or body cavity.

A varicose vein dissector and removal apparatus includes a handle having a first end and a second end, a dissector extending from the first end of the handle and a hook extending from the second end of the handle, and a blade positioned within the dissector for movement between a use position and a storage position. The apparatus is used by creating an initial incision in skin over a varicose vein to be removed, advancing the dissector into the incision and dissecting around the varicose vein to be removed, pushing the dissector against an inner surface of the skin a predetermined distance from the initial incision, exposing the blade by moving it from its storage position to its use position and creating a second incision in the skin letting the dissector protrude out of the skin, and grasping the vein with the hook and removing the vein.

A sheath/catheter system includes a catheter including a proximal end and a distal end, the distal end including a distal tip portion exhibiting controlled hardness and flexibility. The system also includes a sheath including a proximal end and a distal end. The system further includes a mechanism for controlling the hardness and flexibility of the distal tip portion of the catheter. A method for vascular access is achieved by introducing a catheter into a vessel, advancing a sheath over the catheter and into the vessel, altering the catheter or sheath to change the respective flexibility and hardness thereof and further advancing the catheter or sheath within the vascular system to a predetermined location.

A single access dialysis needle system comprises a first cannula, a second cannula or sheath, and a barrier arranged on the outer surface of the first cannula. The distal end of the first cannula extends distal to the distal end of the second cannula or outer sheath, and the barrier is positioned between the respective distal ends. When the barrier is inflated or otherwise activated, it prevents or minimizes recirculation.

A vascular treatment device may include (1) a handle having a motor, a trigger, and a male coupling, and (2) a cartridge, engageable to the handle, having a female coupling, a wire, and a sheath fixed to the cartridge. When the female coupling is not engaged to the male coupling, the sheath may cover the distal end of the wire, allowing safe advancement of the device into the patient's vasculature, and when the female coupling is engaged by the male coupling, the distal end of the wire may be exposed from the sheath and used.

An intrauterine device for applying force to a wall of a uterus to promote contraception without blocking the fallopian tubes may include an elongate member formed of a resilient material and having a default expanded configuration and a spring portion disposed approximately at a midpoint between two ends of the elongate member. The IUD may also include two tissue contact members, one tissue contact member disposed at one of the two ends of the elongate member and the other tissue contact member disposed at the other end. The tissue contact members may generate a laterally directed force against the wall of the uterus when the intrauterine device assumes its default expanded configuration.
