Abstract: An enhanced flexibility catheter is provided, such as for distal neurovascular access or aspiration. The catheter includes an elongate flexible body, having a proximal end, a distal end, and a side wall defining a central lumen. The side wall is formed from a plurality of adjacent tubular segments. At least one segment has a first end face inclined at a non normal angle to a longitudinal axis of the catheter. An adjacent segment has a second end face inclined at a complementary angle to form an inclined junction at the transition between the two segments. The transition serves to provide superior bending characteristics along the length of the catheter shaft.

Abstract: A system for removing embolic material from an intravascular site is disclosed. The system includes an elongate, flexible tubular body, having a proximal end, a distal end, and a tubular side wall defining at least one lumen extending axially there through; an axial restraint carried by the side wall and exposed to the lumen; a rotatable core wire extendable through the lumen, the core wire having a distal end; a limit carried by the core wire, the limit having a bearing surface for rotatably engaging the restraint; and an agitator tip on the distal end of the core wire. The limit and the restraint are engageable to permit rotation of the core wire but limit distal advance of the tip relative to the tubular body.

Abstract: A medical device having a segmented construction. In at least some embodiments, a medical device including a plurality of conductive elongated members that are of such a length and are connected together in such a manner to impart a degree of MRI compatibility to the device. In some embodiments, the elongated members can include a series of solid elongate members and tubular elongate members, which construction provides one way to control at least some properties of the device, for example, stiffness, torque transmission, flexibility, shape retention, and the like. In yet some additional embodiments, at least one of the elongated members has a recess into which a protrusion of another elongated member may fit.

Abstract: A mechanical cavity-creation surgical device and methods and kits for using such devices is described. In one variation, the mechanical cavity-creation surgical device contains a side window at the distal end of a shaft that allows the articulation of a blade, pick, or tip from a position that is inside the shaft to a position that protrudes at least partially from the side window.
