    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 is mounted near the distal end of a steerable guidewire, which guides a therapeutic catheter. An actuator rod 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. Wire having enhanced radiopacity is included in the filter to provide visualization under fluoroscopy.

    摘要： The perivascular leak repair system, and method of using the same, of the present invention provides a sealant reservoir with a repair catheter operably attached; a flow control device disposed between the sealant reservoir and the repair catheter, and the flow control device responsive to a flow control signal; a heart phase detector generating a diastole phase signal; an injection switch generating a injection signal; and a flow controller responsive to the diastole phase signal and the injection signal, and generating the flow control signal. A method of sealing a perivascular leak comprises identifying the perivascular leak; inserting a repair catheter to the perivascular leak; injecting sealant at the perivascular leak; and removing the repair catheter. The sealant can be injected when the heart is in diastole to sweep the sealant into the perivascular leak.

    摘要： The invention includes an exchange system, a guidewire anchoring means and a method of use for catheters exchangeable over a guidewire (55). The guidewire anchoring means restricts movement between the guidewire (55) and the anchoring means. The anchoring means comprises a shaft (35) with a longitudinal lumen (80) therethrough, the lumen (80) being in fluid communication with a balloon (25 or 30) disposed on the distal end of the shaft (35). A tubular split housing (5 or 10) surrounds the distal end of the shaft (35) and adheres to the balloon (25 or 30), the balloon (25 or 30) being sized to expand to a larger size than the inside diameter of the split housing (5 or 10). The inside diameter of the split housing (5 or 10) is sized to slidably receive a catheter, while the outside diameter of the split housing (5 or 10) is sized to slidably fit within a guide catheter (50 ).

    摘要： The percutaneously delivered temporary valve assembly of the present invention, and method of using the same, provides an elongate element and a temporary valve disposed on the elongate element. The temporary valve can comprise struts and a membrane attached to the struts. The elongate element can include at least one lumen. The percutaneously delivered temporary valve assembly can be used to replace an aortic valve by locating a temporary valve in a patient's ascending aorta; deploying the temporary valve; removing the native aortic valve past the temporary valve; implanting the prosthetic aortic valve past the temporary valve; collapsing the temporary valve; and removing the temporary valve from the patient. The temporary valve can be sized to the patient and can be left in place while the prosthetic aortic valve heals in.
