摘要： Material transport catheters and methods for their use rely on rotation of an impeller within a catheter body and a clearing element for preventing buildup of materials at the opening of the catheter body. The impeller preferably comprises an inner tube or shaft having a helical rotor fainted over an outer surface thereof. The clearing element may comprise a free end of a structure near the distal end of the catheter body for disrupting clot, wherein the free end of the structure extends into the distal opening of the catheter body to break up materials as the impeller is rotated. Alternatively, the clearing element may comprise a cutting member disposed at the distal opening of the catheter body.

摘要： The invention is directed to composition, preparation and use of composite materials based on an adhesive with solids levels above 45% by weight that contain stable polyamidoamine-epihalohydrin resins (PAE resins) of solids greater than 40% where the relative high solids of the PAE enables the high solids content of the adhesive. Furthermore, at least 45% of the solids portion of the adhesive is made up of a combination of the solids of the PAE resin and the solids of the protein source. The invention is also directed an adhesive comprised of the PAE in combination with a soy protein source. The invention is also directed toward use of the adhesive in composite materials and in particular wood containing composite materials, and more specifically wood fiber or particle based composites.

摘要： Clot disruption and dissolution are achieved using a catheter having the ability to infuse a thrombolytic agent, aspirate clot and fluid, and allow passage of a guidewire. Optionally, the catheter may also include a mechanical agitator for further disrupt clot in the presence of the thrombolytic agent. A flow resistor in the catheter provides for infusion and/or aspiration to be concentrated primarily at a clot treatment area in a blood vessel while also providing optional infusion and/or aspiration distal to the treatment area. In some embodiments, infusion, aspiration and guidewire passage occur through a common lumen. The thrombolytic agent, such as tPA, streptokinase, or urokinase, is directly released into the clot at the point where the agitator is engaging the clot. In this way, the thrombolytic activity of the agent is enhanced and the dissolution of the clot is improved.

摘要： A system for treating an aneurysm comprises an elongate flexible shaft and an expandable member. An expandable scaffold is disposed over the expandable member and may be expanded from a collapsed configuration to an expanded configuration. A double-walled filling structure is disposed over the scaffold and has an outer wall and an inner wall. The filling structure is adapted to be filled with a hardenable fluid filing medium so that the outer wall conforms to an inside surface of the aneurysm and the inner wall forms a substantially tubular lumen to provide a path for blood flow. In the expanded configuration the scaffold engages the inner wall of the filling structure. A tether is releasably coupled with the filling structure and the flexible shaft thereby constraining axial movement of the structures relative to each other.

摘要： Material transport catheters and methods for their use rely on rotation of an impeller within a catheter body. The impeller preferably comprises an inner tube or shaft having a helical rotor formed over an outer surface thereof. Optionally, in the case of a tubular shaft, a second helical rotor may be provided within the shaft lumen in order to induce flow in opposite or in the same direction as induced by the outer helical rotor. Catheters may further comprise structures near their distal ends for disrupting clot, and are preferably introduceable over guidewires where the helical rotors are rotated directly over the guidewire. The catheters may include two or more impellers or impellers having two or more rotors in order to provide for circulation of materials at a target site within a patient body lumen.

摘要： Clot disruption and dissolution are achieved using a catheter having both an agitator and the ability to deliver a thrombolytic agent. The catheter is introduced to a target region with a blood vessel and the agitator manipulated to engage and disrupt a region of clot therein. The thrombolytic agent, such as tPA, streptokinase, or urokinase, is directly released into the clot at the point where the agitator is engaging the clot. In this way, the thrombolytic activity of the agent is enhanced and the dissolution of the clot is improved.

摘要： Thrombectomy and other treatments are achieved using a catheter having a positioning cage and a macerator within the positioning cage. The catheter is introduced to a target body lumen, typically a blood vessel, and a positioning cage deployed at a treatment site. The macerator is then operated to disrupt thrombus, clot, or other occlusive materials at the treatment site, and the catheter is used to collect and remove the disruptive materials from the body lumen. In particular examples, the macerator may be radially expansible and optionally rotated and/or axially translated within the positioning cage to effect disruption of the occlusive material.

摘要： The present invention provides controlled expansion endoluminal prostheses and methods for their deployment and expansion. The present stent-grafts generally comprise a radially expansible tubular frame and a plastically expansible liner on the frame. Either the frame or the liner includes a reinforcing element which limits expansion of the stent-graft at a predetermined expanded size. In some embodiments, the reinforcing element restrains the frame, for example, by limiting the circumferential diagonals of perforations on a perforate frame structure. Generally, however, the reinforcing element is included in the liner as circumferentially oriented yarn. A particularly advantageous liner includes composite circumferential yarns having inexpansible fibers wrapped around an expansible fiber, such as a partially oriented yarn, PTFE, or the like.
