An angioplasty device has a filter associated with it to capture embolic particles that may be broken free during an angioplasty procedure. In one embodiment the embolic filter has a frame in which struts are connected to end rings and to each other by a plurality of interconnected oval members. In another embodiment the device includes an actuator at the proximal end of an actuator wire. By rotating a knob on the device, the physician can smoothly tension the wire by a predetermined amount to prevent the filter from opening too much or too little. Various other embodiments of filter frames are also disclosed.

A catheter has a section of the catheter shaft adjacent its proximal end in which an outer catheter wall and an inner catheter wall define a space therebetween. An electrode is disposed within the space defined between the inner and outer catheter walls. A magnetorheological fluid fills the space between the inner and outer catheter walls. When an electric current is passed through the electrode, the magnetorheological fluid stiffens, causing the section of the catheter shaft adjacent the proximal end to stiffen.

A percutaneous transluminal angioplasty device includes an embolic filter mounted to the catheter shaft at a location distal to the angioplasty balloon. Thus the filter is downstream from the blockage and is properly positioned to capture embolic particles that may be set loose into the blood stream as the angioplasty procedure is performed. The embolic filter is normally collapsed against the catheter shaft to facilitate introduction and withdrawal of the device to and from the operative site. Once the angioplasty balloon is properly positioned, however, means operatively associated with the embolic filter are actuated to erect the filter to position a filter mesh across the lumen of the vessel.
