Abstract: A dialysis catheter clearance device is for use with a dialysis catheter. The device includes an infusion catheter having a first end, a second end, and a lumen between the first end and the second end. The device also includes a flexible rod, within the infusion catheter. The rod has a first end and a second end. The first end of the rod is connected to a motor, which imparts movement into the rod, and the second end of the rod is located at or about the second end of the infusion catheter. Actuation of the motor imparts movement to the second end of the rod to induce turbulence in clot dissolving medication, thereby increasing the effectiveness of the clot dissolving medication in dissolving a clot located at the second end of the infusion catheter.

Abstract: A vascular filter system and method are disclosed. In one embodiment, the filter system comprises a dispensing needle, a guidewire and a catheter releasably attached to a filter dispenser which stores a length of filter wire. The filter wire dispenser has a guide tube which guides the filter wire into the catheter and then into a vein during surgical implantation. The filter wire is configured to form into a predetermined shape as it is deployed from the needle. The shape of the filter wire captures blood clots in the blood stream. The filter wire may be configured with a perforated section and a non-perforated section. Perforations are in fluid communication with an inner hollow lumen in the filter wire.

The device includes a handle configured to be located exterior to the patient, a knob rotatably coupled to the handle and configured to be located exterior to the patient, a net, a first rod coupled to the knob and the net, and a second rod coupled to the handle and the net. The net is configured to move between a collapsed position and an open position. The net is configured to encapsulate the clot within the vessel of the patient when in the open position. Responsive to the knob rotating with respect to the handle, the first rod is configured to rotate between a first position corresponding to the net being in the collapsed position and a second position corresponding to the net being in the open position.

Abstract: An infusion filter design combines a fluid infusion device and a blood filtration device that filter blood during a thrombolysis procedure while allowing for complete filter removal on procedure completion. In one embodiment, a wire comprises a proximal, non-infusible length that extends partially outside of the patient and within the vein. The wire further comprises an infusible length distally from the non-infusible length that is extends within the vein so as to be placed at the section of the vein requiring medication. The wire also comprises a distal filter component at a distal end of the wire that is employed to filter the blood in the event that during the period that clot is dissolved it migrates toward the central circulation.

Abstract: A dialysis catheter clearance device comprising a medication delivery device configured to connect to the proximal end of the infusion catheter and selectively output an infusion drug into the infusion catheter. An infusion catheter having the proximal end and an opposing distal end, the proximal end of the infusion catheter connected to the medication delivery device, and the distal end of the infusion catheter having an opening through which medication exits the infusion catheter. An infusion catheter placement device is located at or near the distal tip of the infusion catheter and configured to expand to having an outer dimension that is greater than an inner dimension of the dialysis catheter when the infusion catheter placement device is outside the dialysis catheter and contract to an outer dimension that is less than the inner dimension of the dialysis catheter when the infusion catheter placement device is inside the dialysis catheter.

Abstract: A method and apparatus to direct a drug directly at the point needed for a specific duration for dialysis catheters which are made in standard sizes. Disclosed is a combination of a rate and duration-controlled infusion pump and reservoir and a pre-measured infusion catheter with a radiopaque distal tip. Along the length of the infusion catheter there is a luer lock connector and anti-leak valve. The invention is inserted into a dialysis catheter where the preset marking is aligned with the catheter hub and the distal infusion tip rest at or near the end of the dialysis catheter. The infusion unit is then activated, and the drug is delivered at the distal tip of the catheter, at or in the fibrin for maximum effect. The method of use and device saves time and resources as it can be deployed without the need for a surgical suite or heath care team.

Abstract: A graft with adjustable stenosis having a length of tube having tube wall with a central passage between an inlet end and an outlet end. A flexible barrier is located in the length of tube, that, in a default position, forms a narrowed section in the central passage and establishes a stenosis fluid chamber between the tube wall and the flexible barrier. An aspiration port system includes a port reservoir, containing fluid, and a needle entry seal, for needle access to the port reservoir to remove or add fluid. A channel is in fluid communication with the stenosis fluid chamber, the stenosis fluid chamber containing stenosis fluid chamber fluid. A separator is between the channel and the port reservoir. The flexible barrier is biased to a default narrow position. Responsive to fluid being removed from the port reservoir, the flexible barrier moves to increase the diameter of the narrowed section.

Abstract: An improvement to an A-V dialysis graft construction that includes an elongated length of polymer tubing having an inlet end and an outlet end adapted to be attached to access needles. The improvement comprises a normally reduced diameter intermediate portion, providing a pressure drop from the inlet end of the length of polymer tubing to the outlet end for the purpose of improving flow to the extremity, not utilizing excess cardiac output and minimizing venous stenosis. A first embodiment comprises a gradual converging portion of the lumen followed by a gradual diverging portion. A second embodiment comprises an inflatable, annular stenosis balloon, providing a variable stenosis.

Abstract: A blood clot aspiration catheter includes an aspiration/flushing lumen having a distal portion that is insertable into a blood vessel of a patient, an aspiration device configured to create an aspiration phase to aspirate clot and blood into the aspiration/flushing lumen and a flushing phase to flush non-clotted blood from the aspiration/flushing lumen, a one-way valve configured to allow clot and blood to flow through the aspiration/flushing lumen during the aspiration phase and to block flow during the flushing phase, and filter valves configured to filter non-clotted blood to be flushed from the aspiration/flushing lumen.

Abstract: A method for constructing a vascular connector configured to bypass an occluded vessel which comprises a primary graft stem and a venous outflow stem. In general, the primary graft stem accepts a blood flow from an occluded vessel to bypass the occlusion. The venous outflow stem may extend from a wall of the primary graft stem and divert a portion of the blood flow to a native vein or other vessel of the vascular system. This configuration is beneficial in ensuring adequate blood flow at the vascular connector to inhibit the formation of clots and to extend the patency of the vascular connector.
