    摘要: The invention is directed to a guidewire having a distal section with multiple distally tapered core segments with at least two contiguous distally tapering core segments in which the most distal tapered core segment preferably has a greater degree of taper than the proximally contiguous tapered core segment. The invention is also directed to an elongated intracorporeal device, preferably a guidewire or section thereof, that has a core member or the like with a plurality of contiguous tapered segments having taper angles that are configured to produce a linear change in stiffness over a longitudinal section of the device. The device may also have a core section with a continuously changing taper angle to produce a curvilinear profile that preferably is configured to produce a linear change in stiffness of the core over a longitudinal section of the device.

    摘要: A cardiac lead adapted for fixation at least partially within a cardiac vessel. The lead includes, in one embodiment, an elongate lead body defining a proximal region and a distal region including a distal end region having at least one electrode and a distal tip. The distal end region is configured such that the electrode and the distal tip can be implanted in the cardiac vessel. Stiffening structures in the distal region of the lead are adapted to stiffen selected portions of the lead for fixation of the electrode within the cardiac vessel. In some embodiments, the stiffening structures include an implantable member adapted to be implanted in a lumen of the lead. In other embodiments, the stiffening structures include a sheath adapted to be deployed over the lead body. In still other embodiments, the stiffening structures are integral to the lead and/or the lead body.

    摘要: An expandable frame for an embolic filtering device used to capture embolic debris in a body vessel includes a first half frame having a first control arm connected to a second control arm by a partial loop and a second half frame having a first control arm connected to a second control arm by a partial loop. The partial loops cooperatively form a composite loop for attachment of a filtering element which will expand in the body vessel to capture embolic debris entrained in the fluid of the vessel. The lengths and positioning of the first and second control arms of each half frame can be varied to create an expandable frame which conforms to the size and shape of the body vessel in which the filtering device is deployed. Additionally, the radius of the partial loops, along with the length of the arc of the partial loops, can be varied on each of the frames to create a composite filtering assembly that can easily adapt to the size and shape of the body vessel. Additionally, the control arms of the half frames can be disposed either proximally or distally of the composite loop to create a distinct filtering structure.

    摘要: A stent having a structure differentiated in terms of its stiffness. Such differentiation is achieved with the use of a superelastic material that transitions between a relatively soft and malleable phase to a stiffer phase at a transition temperature that is adjustable. By differentially adjusting the transition temperature of different portions of the stent, a differentiation of the stiffness of the structure is achieved upon the stent being subjected to body temperature.

    摘要: A filtering device has a directional member and filtering member disposable in a vessel (e.g. blood artery) at a position past a lesion in the direction of fluid flow. The filtering member is made from a resilient material having properties of passing the fluid while blocking the passage of emboli in the fluid. This material may be selected from a group consisting of blood filter material and a braided/woven biocompatible material with the properties specified above. The inner end of the filtering member is attached to a shaft which provides for the disposition of the members in the vessel at the position past the lesion and the withdrawal of the members from the vessel. The directional member has a length extending at least to the vessel wall. The directional member is made from a pliable and elongatable material with properties of blocking fluid and emboli passage. The directional member is deployable within the vessel by the fluid flow in the vessel and directs the fluid in the vessel and any emboli in the fluid into the filtering member. The filtering and directional members are disposed at an acute angle relative to the shaft to create a trapping pocket. Restraining wires attached to the directional member are used to collapse the directional member and draw at least a part of the directional member into an outer sheath to prevent emboli from backflowing into the vessel.
