摘要： An air passageway obstruction device includes a frame structure and a flexible membrane overlying the frame structure. The frame structure is collapsible upon advancement of the device into the air passageway, expandable into a rigid structure upon deploying in the air passageway and recollapsible upon removal from the air passageway. The flexible membrane obstructs inhaled air flow into a lung portion communicating with the air passageway. The device may be removed after deployment in an air passageway by recollapsing the device and pulling the device proximally through a catheter.

摘要： A medical lubricant suitable for injection into the blood stream of a patient. The lubricant is suitable for use with rotating equipment such as atherectomy drive shafts moving within sheaths and over guide wires and other minimally invasive medical devices introduced into a patient through a catheter like instrument. The lubricant is an oil-in-water emulsion including a surfactant, a co-surfactant, and a pH buffer. The lubricant can further include a cryogenic agent and a pH adjusting agent. One lubricant includes olive oil as an emulsified oil, egg yolk phospholipid as a surfactant, sodium deoxycholate as a co-surfactant, glycerin as a cryogenic agent, L-histidine as a pH buffer, and is pH adjusted using sodium hydroxide. The lubricant also includes a therapeutic agent. The lubricant can withstand freeze/thaw cycles as well as saline dilution, heating, and shear stress without significant creaming, separation, or unacceptable increases in oil droplet size.

摘要： An ablation burr for a rotational atherectomy device that may reduce the risk of damage to a vessel wall while providing ablative cutting surfaces out to the maximum diameter of the burr. Two different abrasive surfaces are provided on the leading surface of the ablation burr. A less aggressive or finer abrasiveness is provided near the ablation burr maximum diameter, which is the portion of the burr nearest the vessel wall. This portion of the burr also presents a relatively shallow angle of attach to the vessel wall. A more aggressive or coarser abrasive is applied to portions of the burr disposed further from the vessel wall. In one embodiment, the more aggressive abrasive portion of the burr has a concave profile, thereby further reducing the possibility that the more aggressive abrasive will contact the vessel wall, even when the burr is rotated significantly away from the vessel axis. The ablation burr body may be profiled with an offset or stepped sections on the leading surface that are dimensioned such that the abrasive particles do not extend radially beyond the maximum diameter of the smooth back surface of the ablation burr.
摘要翻译：用于旋转粥样斑块切除装置的消融毛刺，其可以减少损伤血管壁的风险，同时将烧蚀切割表面提供到毛刺的最大直径。两个不同的研磨表面设置在消融毛刺的前表面上。在消融毛刺最大直径附近提供较少的侵蚀性或更细的磨蚀性，其是最靠近血管壁的毛刺部分。毛刺的这一部分也呈现出相对较浅的附着于血管壁的角度。将较为侵蚀性或较粗糙的研磨剂施加到设置在血管壁之外的毛刺部分。在一个实施例中，毛刺的更具侵蚀性的研磨部分具有凹形轮廓，从而进一步降低了更具侵蚀性的磨料将与血管壁接触的可能性，即使当毛刺被显着地远离血管轴线旋转时。消融毛刺体可以在引导表面上具有偏移或阶梯部分的形状，其尺寸被设计成使得磨料颗粒不会径向延伸超出消融毛刺的平滑后表面的最大直径。

摘要： A method for treating loosely formed, friable or fragile lesions in a patient's blood vessel. A catheter having a pair of sealing mechanisms is advanced such that the sealing mechanisms are positioned distal to and proximal to the lesion. The sealing mechanisms are activated to seal the vessel on either side of the lesion. A medication is then delivered through the catheter to the sealed area of the vessel. The medication interacts with the lesion in order to partially or completely solidify it. Once the lesion is solidified, the catheter is removed and the lesion can be treated with a conventional intravascular device.

摘要： An atherectomy burr includes a number of cutting blades having a less aggressive cutting action when rotated in a first direction and a more aggressive cutting action when rotated in a second direction. In accordance with one embodiment of the invention, each cutting blade includes an abrasive surface that is substantially parallel to the outer surface of the cutting burr. Each blade further includes a second cutting surface that is substantially perpendicular to the outer surface of the burr. By selectively rotating the burr in either direction, a physician can cause the less aggressive or more aggressive cutting surface to engage deposits in a patient's vessel.
