Interface Devices, Systems, And Methods For Use With Intravascular Pressure Monitoring Devices

摘要

Embodiments of the present disclosure are configured to assess the severity of a blockage in a vessel and, in particular, a stenosis in a blood vessel. In some particular embodiments, the devices, systems, and methods of the present disclosure are configured to provide FFR measurements over a length of a vessel of interest in a small, compact device that integrates with existing proximal and distal pressure measurement systems and does not require a separate power source.

主权项

1. An interface for intravascular pressure sensing devices, comprising:
a distal input configured to receive a distal pressure signal from a distal pressure sensing device; a proximal input configured to receive a proximal pressure signal from a proximal pressure sensing device; a pullback device configured to interface with a proximal portion of the distal pressure sensing device to cause translation of the distal pressure sensing device relative to the proximal pressure sensing device; a processor in communication with the distal input, proximal input, and the pullback device, the processor configured to calculate a pressure differential between the distal pressure and the proximal pressure based on the received distal pressure signal and the received proximal pressure signal obtained as the pullback device translates the distal pressure sensing device relative to the proximal pressure sensing device; and a display in communication with the processor and configured to display the pressure differential calculated by the processor including a relative position of the distal pressure sensing device to the proximal pressure sensing device associated with the calculated pressure differential.
