    摘要： An endovascular laser treatment device for causing closure of a blood vessel uses an optical fiber adapted to be inserted into a blood vessel. An inner sleeve is arranged around a distal portion of the optical fiber core such that both distal ends of the inner sleeve and the optical fiber core form an enlarged light emitting face. The enlarged emitting face provides substantially lower power density while providing the same amount of total energy during a treatment session. An outer sleeve arranged around the inner sleeve acts as a spacer to position the light emitting face away from an inner wall of the blood vessel. The enlarged light emitting face and the outer sleeve acting as a spacer reduces the possibility of thermal run-away and device damage, and reduce the possibility of vessel perforations, leading to less bruising, post-operative pain and other clinical complications. In yet another aspect of the present invention, a spacer comprises an inner sleeve and an outer sleeve both arranged around a distal portion of the core to prevent the laser light from traveling laterally and to position the light emitting face away from an inner wall of the vessel. The inner sleeve can be a heat resistive material such as ceramic and the outer sleeve can be, for example, a metallic sleeve to provide structural integrity and strength to the distal section of the treatment device.

    摘要翻译： 用于引起血管闭合的血管内激光治疗装置使用适于插入血管的光纤。 内套筒围绕光纤芯的远端部分布置，使得内套管的远端和光纤芯形成放大的发光面。 放大的发射面提供显着更低的功率密度，同时在治疗期间提供相同量的总能量。 布置在内套筒周围的外套管用作间隔件，以将发光面定位成离开血管的内壁。 放大的发光面和作为间隔物的外套筒减少了热损失和器件损坏的可能性，并减少了血管穿孔的可能性，导致较少的瘀伤，手术后疼痛和其他临床并发症。 在本发明的另一方面，一种间隔件包括内套筒和外套筒，两个外套筒均布置在芯体的远端部分周围，以防止激光横向移动，并将发光面朝远离内壁 船只。 内套筒可以是诸如陶瓷的耐热材料，并且外套筒可以是例如金属套筒，以向治疗装置的远端部分提供结构完整性和强度。

    摘要： A catheter retention assembly and method of use with a catheter. The assembly has a carrier system and a cuff positioning device with an in-growth cuff and a lumen having an inner wall adapted to be mounted on the outer surface of the catheter, and a carrier system with an inner surface and an outer surface in contact with the inner wall of the cuff positioning device. The carrier system holds the lumen in a first radial state. When the carrier system is removed, the lumen contracts to a second radial state, and the inner wall of the cuff positioning device provides sufficient surface adherence to the outer surface of the catheter, so as to maintain the position of the cuff positioning device relative to the catheter, and to allow for catheter exchange.

    摘要： A vascular access catheter that has a substantially distal end portion that has a distal tip. The distal end portion has a sloped face in the distal portion of the catheter, an outflow lumen aperture, and a second inflow lumen aperture. The outflow lumen aperture is substantially completely open in the sloped face and exits the distal portion adjacent the distal tip. The catheter has a guidewire lumen that is located at least in the region of the distal portion of the catheter and is capable of receiving a guidewire. The guidewire lumen has a proximal aperture and a distal aperture that extends distally of the outflow lumen aperture. The guidewire distal aperture exits at the distal most edge of the distal end portion. The guidewire lumen may extend a partial length of the catheter or substantially the entire length of the catheter. The catheter distal portion may be substantially straight or curved.

    摘要： A compact retrievable blood clot filter has a filter section, a releasable lock and an alignment section connected to the filter section. Alignment ribs of the alignment section have releasable upstream ends that are locked to the filter by the releasable lock. The releasable upstream ends of the alignment ribs are capable of being released from the releasable lock so that during retrieval of the filter, the alignment ribs can slide through the endothelial tissue that may have grown around the alignment ribs.
