摘要： Devices, systems, and methods for performing thrombectomy procedures are disclosed herein. The devices can include an aspiration catheter which optionally has a beveled distal end. The aspiration catheter is advanced to a position adjacent a thrombus. A blocking element can be expanded near the distal end of the aspiration catheter to block fluid flow during the procedure. The devices can include a thrombus retrieval device supporting a braided assembly that grips and facilitates removal of the thrombus. The braided assembly is expandable to a range of expanded outer diameters by varying the level of tension in an activation wire attached thereto. An expander can be deployed beneath the braided assembly to exert an outward expansion force upon the braid, thereby increasing the grip between the braided assembly and the thrombus. The braided assembly contacts the thrombus and the retrieval device pulls it proximally toward the aspiration catheter.

摘要： Devices, systems, and methods are disclosed that help deliver catheters or other medical devices to locations within a patient's body. The device includes a transporter catheter having a proximal end and a distal end, at least a first balloon located adjacent to the distal end, and at least a second balloon located between the first balloon and the proximal end of the transporter catheter. The first balloon is configured for holding a prosthetic device in place. In another embodiment, the transporter catheter has a third balloon, an orienting balloon, substantially at the tip of the distal end of the transporter catheter.

摘要： Inflatable devices are disclosed including a surface which has a network of polymer chains and is configured to be inflatable into a therapeutically or diagnostically useful shape, and at least one ultrashort laser pulse-formed modification in the surface. The network can, for example, include a network morphology that is substantially unchanged by modification with the ultrashort pulse laser. Ultrashort laser pulses can be laser pulses equal to or less than 1000 picoseconds in duration. Advantageously, the etching process uses a relatively low-heat laser to avoid significant heating of surrounding polymers while modifying the surface (and other structures) of the device. The process is configured so that the polymer chain morphology adjacent the modification is substantially unaffected by the low-heat laser. The resulting inflatable device has customized surface features while still retaining substantially homogenous polymer network morphology. This preserves the elasticity, especially the surface elasticity, of the inflatable device.

摘要： A catheter is provided for both crossing a lesion, such as a chronic total occlusion, in a vessel and performing percutaneous transluminal angioplasty thereupon. The catheter includes a shaft having a tapered tip adapted for being pushed into the lesion to advance through the lesion. An inflatable balloon is mounted on the shaft, which may be braided to provide enhanced pushability and kink-resistance. The inflatable balloon includes a proximal portion and a distal tapered portion connected to the tapered tip, and having a shallow taper. The taper of the distal tapered portion and the tapered tip may together create a continuous sloping transition from a distal end of the distal tapered portion to an adjacent portion of the tapered tip to facilitate crossing a lesion. The balloon may also be selectively inflated or deflated during crossing of the lesion, and ultimately used to compact the lesion when inflated.

摘要： A medical balloon includes an outer layer and an inner layer. The outer layer has a surface texture or formation, such as a scoring element. The inner layer is made of a reflow material which during production of the balloon from a raw tubing will soften and flow into internal recesses in the outer layer, thereby filling these recesses and providing support to the outer layer formations so as to avoid flattening of these formations during use of the balloon. The balloon can be manufactured in a single formation step from raw tubing having the outer and inner reflow layer coextruded.

摘要： A balloon in which a rupture in a circumferential direction can be prevented from occurring, and a method of manufacturing the same is disclosed. The balloon is configured to be arranged on a medical catheter, and includes a dilatable cylindrical portion formed with a birefringent polymer material. A ratio of the number of orientation distributions, calculated by dividing the number of orientation distributions of the cylindrical portion in a circumferential direction by the number of orientation distributions of the cylindrical portion in an axial direction, is less than 2.
