摘要： The present invention is a temporary intraluminal filter guidewire for use during interventional procedures, such as angioplasty or stent deployment. A braided filter (25) is mounted near the distal end of a steerable guidewire (150), which guides a therapeutic catheter. An actuator rod (62) slides over the guidewire and is removably connected to the filter. The rod controls relative displacement of the filter ends, causing transformation of the filter between a deployed configuration and a collapsed configuration. In several embodiments, the guidewire distal to the filter has a fixed tip length. Other embodiments of the invention include a mechanism for damping (95) longitudinal movement between the distal and proximal ends of the filter.

摘要： A guidewire apparatus for use during percutaneous catheter interventions, such as angioplasty or stent deployment. A protection element comprising a filter or an occluder is mounted near the distal end of a steerable guidewire, which guides a therapeutic catheter. The guidewire apparatus comprises a hollow shaft movably disposed about a core wire and, optionally, a slippery liner interfitted there between. The shaft and core wire control relative displacement of the ends of the protection element, causing transformation of the protection element between a deployed configuration and a collapsed configuration.

摘要： Protection device for filtering fluid flowing through a lumpen of a vessel in a patent's vascular system having an elongate support member carrying a filter element (41) expandable from a delivery configuration to an expanded deployed configuration when the filter element is deployed in the body lumen. The proximal end of the filter is connected at the distal end of a proximal elongate support segment (42) of the support member and the distal end of the filter element is connected at the proximal end of the distal element (46). The filter element (41) defines an interior cavity in which no substantial portion of the elongate support member lies, and a plurality of openings to capture particles greater than a predetermined size inside the cavity of the filter element.

摘要： A rotational atherectomy system is disclosed, comprising: an elongated, flexible spin-to-open drive shaft having a distal end for insertion into a vasculature of a patient and having a proximal end opposite the distal end remaining outside the vasculature of the patient; a concentric or eccentric abrasive element, preferably a solid crown, attached to the drive shaft proximate the distal end of the drive shaft; an electric motor rotatably coupled to the proximal end of the drive shaft, the electric motor being capable of rotating the drive shaft in a spin-to-open direction; and control electronics for monitoring and controlling the rotation of the electric motor. When an obstruction at the distal end is detected by the applied torque and/or current reaching a predetermined maximum allowed level and with the drive shaft opened to a maximum allowed outer diameter, power to the motor is eliminated.

摘要： A device for performing therapeutic or diagnostic procedures within the cerebrovasculature includes a catheter having a distal portion, a proximal portion and a lumen extending therebetween, the catheter including an expandable region for engaging the vessel wall, thrombus, atheroma, or other structures. The device further includes an elongate stretching member, which can be a guidewire, insertable longitudinally through the lumen of the catheter, the elongate stretching member being configured for stretching at least a portion of the catheter and causing the expandable region to transition from an expanded state to a collapsed state, and wherein the elongate stretching member is retracted proximally relative to the catheter causes the expandable region to transition from the radially collapsed state to a radially, or laterally expanded state.
