An intravascular ultrasound (IVUS) device that includes a flexible elongate member having a proximal portion and a distal portion; a controller coupled to the distal portion of the flexible elongate member; an ultrasound transducer disposed at the distal portion of the flexible elongate member and in communication with the controller; a pressure transducer disposed at the distal portion of the flexible elongate member and in communication with the controller; and plurality of conductors extending from the controller to the proximal portion of the catheter, at least one conductor of the plurality of conductors being configured to carry both the signals representing information captured by the ultrasound transducer and information captured by the pressure transducer.

Catheter with integrated controller for imaging and pressure sensing

An apparatus for assessing the severity of stenosis in a blood vessel includes an elongate body including a distal portion and a centering assembly. The centering assembly is actuatable to selectively center the elongate body in the vessel. A pressure sensor is disposed adjacent the centering assembly and is configured to detect fluid pressure in the vessel. A processing system receives the measured pressure from the pressure sensor, receives data representing the cross-sectional area of the vessel, receives data representing the size of the distal portion, calculates a offset correlation based on the size of the distal portion and based on the size of the vessel, and calculates a fractional flow reserve (FFR) for the vessel as an index of stenosis severity taking into account the offset correlation and the measured fluid pressure from the pressure sensor.

Device, system, and method for assessing intravascular pressure

Embodiments of the invention relate generally to devices and methods for providing filtration of debris within a body lumen. More particularly, embodiments of the invention related to devices and methods for providing distal protection to a medical procedure by filtration of debris generated by the medical procedure using filters having a frame with a slidable crossover point.
