摘要： An endovascular treatment method for causing closure of a blood vessel is provided. The method includes inserting into a blood vessel an optical fiber having a core through which a laser light travels and a spacer sleeve arranged around a distal portion of the core. A distal end of the core defines an enlarged light emitting face, which advantageously provides substantially lower power density while providing the same amount of total energy during a treatment session. After the insertion, laser light is applied through the light emitting face while the inserted optical fiber and spacer sleeve are longitudinally moved. The spacer sleeve positions the light emitting face away from an inner wall of the blood vessel and application of the laser light causes closure of the blood vessel.

摘要： A central venous catheter is provided having an outer tubular member and an inner tubular member that are preferably formed as a single integrated tube containing polymer material of different durometer and varying amounts of radiopaque filler material. The polymer durometer of the inner tubular member is higher than the polymer durometer of the outer tubular member. The percentage by weight of the filler material contained in the inner tubular member is higher than that of the outer tubular member. The combination of the higher durometer inner tubular member and the lower durometer outer tubular member along the length of the tube provides the desired tensile strength, hardness, chemical resistance and fatigue resistance and at the same time provides the desired flexibility and radiopacity.

摘要： A device for withdrawing a tubular body part such as a varicose vein is provided. A needle is inserted through a skin. The needle contains therein an engaging element in an undeployed state. After the needle is inserted, the engaging element is pushed out of the needle and is typically deployed inside the vein. The vein is now ready to be withdrawn by the deployed engaging element. Using a puncture device that also contains a deployable engaging element allows the puncture site to be small and causes less trauma to the surrounding tissue.

摘要： An elongated thermal energy delivery device for use in endovenous thermal treatment of blood vessel is provided. The energy device includes a flexible guide tip attached to its distal portion which provides for direct tracking and advancement of the energy device through the vein without the use of a treatment sheath. Also provided is a method of using the thermal energy delivery device with flexible guide tip. The method eliminates the need for a treatment sheath and accessory procedural components and the procedural steps associated with these components.

摘要： A vascular access catheter is disclosed that has a catheter shaft distal tip with an angled edge positioned at an acute angle relative to a longitudinal axis of the catheter shaft. A first, second, and third lumen extend longitudinally through the entire catheter shaft. The third lumen is configured for receiving a guidewire. The first lumen has an aperture located in the angled edge of the catheter next to the distal tip and communicates with the first lumen. The second lumen has an aperture that is positioned in the outer surface of the catheter shaft that is in communication with the second lumen, and is spaced proximally from the first lumen aperture. A port is positioned in the outer surface of the catheter shaft that is in communication with the third lumen and the outer surface of the catheter shaft, and is spaced proximally from the second lumen aperture.

摘要： A permanent blood clot filter which may be retrieved is provided. The blood clot filter includes a filter section and an alignment section. The filter section includes a filter hub and a set of filter legs whose downstream ends are connected to the filter hub. The filter legs extend axially and radially outwardly from the filter hub to form a conical configuration. The alignment section includes an alignment hub and a set of alignment ribs whose downstream ends are connected to the alignment hub and whose upstream ends are connected to the filter legs. The alignment ribs extend from the alignment hub radially outwardly and then further extend radially inwardly to provide centering of the filter.

摘要： An endovascular laser treatment device designed to be used with an optical fiber to treat venous diseases such as varicose veins is provided. The device includes a spacer that positions the distal end of the optical fiber away from the inner wall of the blood vessel during delivery of laser energy to provide an even distribution of thermal energy around the vessel, thereby avoiding vessel perforation and incomplete vessel collapse.

摘要： Disclosed are various embodiments of a hemo-dialysis catheter in which the aspirating port at the end of the aspirating tube is distal of the infusion port or ports at the end of the infusion lumen. The infusion port or ports are arranged circumferentially so that the infused filtered blood is a substantially 360° jet of fluid with a substantial radial component. This jet of fluid serves to abrade the occlusive material that is composed of fibrin and other components that grows down along the outer wall of the catheter that would otherwise tend to block off the ports. Stopping occlusion growth at the zone of the infusion ports prevents further growth distally to the aspirating port and protects the aspirating port from being blocked by the growth of occlusion.
