摘要： The invention encompasses methods and apparatus for pumping fluid from one location to another through the repetitive expansion and collapse of bubbles generated as a result of the absorption of repetitive pulses of radiation in a fluid. This pumping phenomenon can be used to aid removal of a total or partial occlusion in a body passage by emulsifying the occlusion with acoustic shock and pressure waves or by mechanically disrupting the occlusive material.

摘要： Apparatus for pumping fluid from one location to another via generation of bubbles in fluid, and expansion and callapse thereof, are described. These apparatus deliver repetitive pulses of radiation to a fluid to form bubbles therein. The expansion and collapse of the bubbles cause fluid motion or pumping. This pumping can be used to facilitate removal of a total or partial occlusion in a body passage by a variety of mechanisms. The apparatus are flexible to facilitate use within a body passage.

摘要： Methods and apparatus for creating fluid flow from one location to another are disclosed. The fluid flow is created via the absorption of repetitive pulses of radiation in a fluid to generate bubbles that expand and collapse repetitively. This fluid mechanism, or pumping phenomenon, can be used to aid removal of a total or partial occlusion in a body passage by disrupting a surface of the occlusion with acoustic shock and pressure waves and/or by causing mechanical disruption of the occlusive material. Appropriate selection of materials and particular constructions improve apparatus flexibility.

摘要： Described herein are flexible implantable occluding devices that can, for example, navigate the tortuous vessels of the neurovasculature. The occluding devices can also conform to the shape of the tortuous vessels of the vasculature. In some embodiments, the occluding devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Some embodiments describe methods and apparatus for adjusting, along a length of the device, the porosity of the occluding device. In some embodiments, the occluding devices allows adequate blood flow to be provided to adjacent structures such that those structures, whether they are branch vessels or oxygen-demanding tissues, are not deprived of the necessary blood flow.

摘要： The invention is directed to a grasping device and system and the method of using the device and system for capturing a thromboembolism and other objects or masses within a patient's body lumen, particularly from within a patient's cerebral blood vessels. The grasping device has an elongated core member with a grasping assembly of arms on the distal end of the core member which have an expanded and a contracted configuration. The expanded configuration permits the arms to surround an object such as a thrombus or clot and a contracted configuration to grasp or capture the object. The distal ends of the arms are provided with object grasping members such as one or more teeth to facilitate the capture and removal of the object. A delivery catheter and a shorter guide catheter aid in delivering the grasping device to the desired intravascular location within the patient.

摘要： An intracorporeal grasping device includes a tubular member for entering a lumen of a human body and the tube member having a distal end portion. An elongated core member is disposed with the interior cavity of the tubular member for rotational or slidably movement within the tubular member and the elongated core member having a proximal end portion and a distal end portion. The elongated core member comprises a uniform diameter tube having some flexibility at the proximal end portion and greater flexibility while along a longitudinal axis in a direction towards the distal end portion; and a grasping configuration is provided for capturing an object (e.g., clot or debris) therein and the assembly may have a proximal end secured to the distal end of the elongated core member. The configuration has an expanded and contracted configuration, and distal sections configured to grasp an object. The grasping configuration may be formed by at least one movable jaw attached to the distal end portion of the elongated core member and a length portion of the distal end portion of the tube member. The grasping configuration may include unitarily formed plurality of movable jaws attached to the distal end portion of the elongated core member. Further, the grasping configuration may be formed by a plurality of loop members attached to the distal end portion of the elongated core member. Further, the grasping configuration may be formed by at least one spiral member having a distal tip for penetrating an object to be removed from a human body lumen. The device has the spiral member provided at the distal end portion of the elongated core member. The grasping configuration can be formed by at least one web member for retaining an object to be removed from a human body lumen, the web member being provided at the distal end portion of the elongated core member.
