A vascular impedance measuring device may comprise a processing component capable of processing raw pressure and flow wave data and a pressure measuring component capable of providing pressure wave data from a specified point in a vessel and forwarding the pressure wave data to the processing component. The device may further include a flow measuring component capable of providing flow wave data from the specified point or a point near the specified point in the vessel and forwarding the flow wave data to the processing component. The processing component processes the raw pressure and flow wave data to produce an estimation of vascular impedance of the vessel from the specified point of measure and may provide data to a feedback system for therapy.

Vascular impedance measuring device and method of determining impedance

A device and methods for treating an aneurysm includes a catheter capable of insertion into a body to be positioned adjacent the aneurysm, the catheter including a distal end and an operator end opposite the distal end. The catheter forms a circular pathway extending between the distal end and the operator end. A partitioner extends through the pathway of the catheter, the partitioner being rotatable within the catheter and including one or more lumens that provide an orifice from a first end of the partitioner to a second end of the partitioner. The device further includes a first coil extending through the partitioner from the first end to the second end in a first lumen and a second coil extending through the partitioner from the first end to the second end in a second lumen. The first and second lumens may be fully circumscribed by the partitioner and have first and second diameters, respectively.

A bifurcated catheter, which can deploy a bifurcated stent constructed as a single piece into a bifurcated vessel, is disclosed. The system may have two main parts&#x2014;a y-shaped catheter with a splittable seam, and a custom made stent, which can be deployed with the bifurcated catheter. The disclosed bifurcated catheter permits a physician or operator to stent a vessel at a bifurcation of the vessel.
