摘要： Described herein are devices, systems and methods for cutting tissue in a patient. In some embodiments, a tissue modification region of a device includes a pair of flexible elongate cutting members extending along the length of the tissue modification region. Each elongate cutting member may be configured to cut a discrete trough into tissue to a depth that is greater than the thickness of the cutting member. In some embodiments, the device includes a spacer. The spacer may be sized and configured to operate in one of two modes. A first mode, in which the spacer is coupled to the cutting members such that it holds a portion of each of the two cutting members a distance from one another, and a second mode, in which at least a portion of the spacer is moved away from a cutting member to allow the cutting members to cut further into tissue.

摘要： An assembly for occluding a vascular site (e.g., an aneurysm) of a human or veterinary patient includes a vaso-occlusive member, a pusher member having a distal end and a severable junction located proximal to the distal end, and a pivotable coupling that couples the pusher member to the occlusive member. A delivery catheter can be used to deliver the vaso-occlusive member to the vascular site. A method of using the assembly to occlude an aneurysm having an aneurysmal sac and an aneurysmal neck, includes locating the catheter within the aneurysmal neck, and manipulating the pusher member to place the vaso-occlusive member within the aneurysmal sac. The method further includes severing the severable junction to detach the vaso-occlusive member from the pusher member. As a result, an axial force is applied by the vaso-occlusive member in a proximal direction, which buckles the pivotable coupling to laterally deflect the axial force. The lateral deflection of the axial force caused by the buckling of the pivotable coupling prevents the catheter from being displaced from the aneurysmal neck by the axial force.

摘要： Described herein are methods and systems for precisely placing and/or manipulating devices within the body by first positioning a guidewire or pullwire through the body from a first location, around a curved pathway, and out of the body through a second location, so that the distal and proximal ends of the guidewire extend from the body, then pulling a device into position using the guidewire. The device to be positioned within the body is coupled to the proximal end of the guidewire, and the device is pulled into the body by pulling on the distal end of the guidewire that extends from the body. The device may be bimanually manipulated by pulling the guidewire distally, and an attachment to the device that extends proximally, allowing control of both the proximal and the distal ends. In this manner devices (and particularly implants such as innerspinous distracters, stimulating leads, and disc slings) may be positioned and/or manipulated within the body. Devices to modify tissue may also be positioned or manipulated so that a target tissue within the body is modified.

摘要： Described herein are elongate device for modifying tissue having a plurality of flexibly connected rungs or links, and methods of using them, including methods of using them to decompress stenotic spinal tissue. These devices may be included as part of a system for modifying tissue. In general, these devices include a plurality of blades positioned on (or formed from) rungs that are flexibly connected. The rungs are typically rigid, somewhat flat and wider than they are long (e.g., rectangular). The rungs may be arranged, ladder like, and may be connected by a flexible connector substrate or between two or more cables. Different sized rungs may be used. The blades (on the rungs) may be arranged in a staggered arrangement. A tissue-collection or tissue capture element (e.g., chamber, bag, or the like) may be used to collect the cut or modified tissue. In some variations the tissue modification devices may have a non-linear axial shape, or may be converted from a first axial shape to a second axial shape.

摘要： Methods and devices for measuring the size of a body lumen and a method for ablating tissue that uses the measurement to normalize delivery of ablational energy from an expandable operative element to a luminal target of varying circumference are provided. The method includes inserting into the lumen an expandable operative element having circuitry with resistivity or inductance that varies according to the circumference of the operative element, varying the expansion of the operative element with an expansion medium, measuring the resistivity of the circuitry, and relating the resistivity or inductance to a value for the circumference of the operative element. In some embodiments the sizing circuit includes a conductive elastomer wrapped around the operative element. Other embodiments of the method apply to operative elements that include an overlapping energy delivery element support in which the overlap varies inversely with respect to the state of expansion, and which is configured with sizing electrodes that sense the amount of the overlap.
