摘要： Devices constrain a distal portion or region of a wire, such as a guidewire or a filterwire, from movement at or near a proximal portion or region of the wire. A magnetic field may be used to constrain a wire passing through a hub. A clamping apparatus may include first and second clamps that, when used in combination, restrain wire movement while advancing an exchange device. A guide catheter may include an anchor movable between an open configuration and a closed configuration.

摘要： An emboli capturing filter device and system are provided. The filter device includes an expandable filter disposed about an elongate member. The filter has a proximal mouth portion facing the proximal end of the elongate member, and a distal portion extending toward to distal end of the elongate member. A support arm is coupled to the elongate member and mouth portion of the expandable filter. When the filter is in an expanded orientation, the support arm is attached to the elongate member at or distal of the mouth of the filter.

摘要： An intravascular balloon catheter including a dilation balloon is provided. The intravascular balloon catheter includes a shaft assembly including a proximal end, a distal end, and an inflation lumen extending longitudinally therethrough. The dilation balloon is operably coupled proximate the distal end of the shaft assembly, such that an interior chamber of the dilation balloon is in fluid communication with the inflation lumen. In one aspect of the invention, a core wire is disposed within the inflation lumen of the shaft assembly. In another aspect of the invention, a tubular member extends longitudinally over the exterior of the dilation balloon for receiving a guidewire.

摘要： A dilation balloon is provided for an intravascular catheter having an elongated shaft with a proximal portion, a distal portion, and an inflation lumen extending therethrough. In one aspect of the invention, the dilation balloon includes a balloon member having a chamber therein in fluid communication with the inflation lumen. The balloon member defines a portion of a guide wire lumen which coextends with a portion of the balloon member for receiving a guide wire. In another aspect of the invention, a balloon is connected to the distal portion of the catheter shaft and a guide wire lumen is spaced exteriorly from the shaft and coextends with a portion of the balloon. In yet another aspect of the invention, a process for making a dilation balloon includes the step of providing a longitudinal member having a first elongated lumen and a second elongated lumen. A first portion of the longitudinal member which defines the first lumen is blow molded into an inflatable balloon which defines an interior chamber for receiving inflation fluid. A second portion of the longitudinal member which defines the second lumen is blow molded into a longitudinal rib which defines a guide wire lumen coextending with said chamber.

摘要： A catheter having a flexible outer tube and a lubricious inner tube bonded within the flexible outer tube. One catheter has a distal outer tube formed of a substantial portion of a first, flexible material, an inner tube having a lubricious inside wall surface formed of a second, lubricious material, and an outer tube wall surface compatible with heat bonding the inner tube outside wall surface to the outer tube wall surface. A preferred flexible material is polyether block amide (PEBA) and a preferred lubricious material is polyethylene. One catheter utilizing the invention includes a flexible distal outer tube having an orifice through the tube wall and an inner tube inserted through the orifice having a lubricious inner layer surrounded by a tie-layer, surrounded in turn by the same flexible material forming the outer tube. One catheter has a PEBA outer tube heat bonded to a tri-layer inner guide wire tube formed of a polyethylene inner layer, a PEBA outer layer, and a PLEXAR™ tie-layer disposed between the inner and outer layers.
