摘要： At the present time, physicians often treat patients with atrial fibrillation (AF) using radiofrequency (RF) catheter systems to ablate conducting tissue in the wall of the Left Atrium of the heart around the ostium of the pulmonary veins. These systems are expensive and take time consuming to use. The present invention circular ablation system CAS includes a multiplicity of expandable needles that can be expanded around a central axis and positioned to inject a fluid like ethanol to ablate conductive tissue in a ring around the ostium of a pulmonary vein quickly and without the need for expensive capital equipment. The expansion of the needles is accomplished by self-expanding or balloon expandable structures. The invention includes centering means so that the needles will be situated in a pattern surrounding the outside of the ostium of a vein. Also included are members that limit the distance of penetration of the needles into the wall of the left atrium, or the aortic wall. The present invention also has an important application to ablate tissue around the ostium of one or both renal arteries, for the ablation of the sympathetic nerve fibers and/or other afferent or efferent nerves going to or from each kidney in order to treat hypertension.

摘要： A catheter system for treating lesions is provided. The system is suitable for treatment of bifurcation lesions, has a low profile and provides substantially predictable translational and rotational positioning. In one embodiment, the system includes a fixed wire balloon catheter and a partially attached guidewire lumen, wherein the guidewire lumen is attached to the catheter at a crotch point. The location of the crotch point is predetermined so as to provide substantially predictable positioning. Several embodiments of the system are described for various types of lesions and vessel configurations.

摘要： A catheter for centrally crossing an occluded blood vessel includes a catheter body having a distal end, a proximal end, and a central passage. A rotatable drive shaft extending through the central passage and has a distal end, a proximal end, and a central lumen. A cutting tip is mounted on the distal end of the rotatable drive shaft and configured to cut through occlusive material when rotated. A plurality of spiral or other flat springs is disposed circumferentially about a distal portion of the catheter body to maintain centering of the catheter and form a passage as the catheter is advanced through a chronic total occlusion.

摘要： A device for removing an obstruction from a lumen in a human or animal subject may include an inflatable balloon. The inflatable balloon may include a proximal tapered portion having a proximal taper angle, a central portion, and a distal tapered portion having a distal taper angle that is greater than the proximal taper angle. The balloon may also include at least one eversion feature on the proximal tapered portion and/or the distal tapered portion. The eversion feature may facilitate preferential eversion of the distal tapered portion into an inside of the balloon without the proximal tapered portion collapsing. Preferential eversion of the distal tapered portion may be provided by the differences in the distal and proximal taper angles and by one or more of a number of different types of eversion features.

摘要： Medical methods and devices for treating aortic dissections. A catheter-based cutting device permits cutting a septum of acute or chronic aortic dissections, in a retrograde manner. The catheter includes a base section having a central lumen therethrough, two flexible arms extending from a distal end thereof, where each arm has a channel therethrough for a passage of a guide wire. With distal ends of the two flexible arms separated, the two arms form a Y-shape with the base section. With distal ends of the two flexible arms together, the two arms have a longitudinal profile, about a periphery thereof, identical to a longitudinal profile of the base section. A non-mechanically actuated cutting component resides between the two arms in a vicinity of the distal end of the base section. The cutting component faces distally outward between the two arms with the distal ends of the two flexible arms separated.

摘要： Intracavitary brachytherapy tandem and ovoid oncology treatment systems and methods are provided. One such system and method employs a multi-part tandem having a detachable distal section suitable for retaining within a body cavity such as the uterus, both during radiation treatment and during recovery time between radiation treatments. This distal portion can be intended for single-patient use and be disposed of after completion of a radiation treatment session having multiple radiation dose treatment times. One or both of real time in vivo detection and monitoring and hypertherapy features can be included. One or more of the system tandem or ovoid colpostats feature bendability to tailor the system to the specific body and patient being treated. The method includes having a tandem distal section inserted into a body cavity such as a uterus and remaining within the body cavity in between treatment times. Other systems and methods incorporate balloon devices that assist in spacing radiation doses away from body sites at which radiation treatment is not intended. Balloon devices also can be provided for adjusting and maintaining separation spacing between two ovoid colpostats while intracavitary.
