20130345574 | Apparatus and Method of Characterising a Narrowing in a Fluid Filled Tube - A system and method for characterising a narrowing in a fluid filled tube, the system comprising: a probe having a first measurement sensor to take an instantaneous measurement at different locations along the tube; a mechanism to draw the probe through the tube; a position measure to provide location data relating to the location at which a respective instantaneous measurement is taken by the first measurement sensor; a processor to calculate, from the instantaneous measurements, a characteristic of the tube at different locations along the tube. | 12-26-2013 |
20140180072 | System and Method for Precisely Locating an Intravascular Device - Systems and methods for locating invasive intravascular devices within a vascular system are provided. In one embodiment, an invasive medical sensing system is disclosed. The system comprises a flexible elongate member having a plurality of radiation-sensitive components arranged around an outer circumferential surface of the flexible elongate member. The plurality of radiation-sensitive components is arranged such that an orientation of the flexible elongate member can be determined when the sensors are exposed to radiation produced by a radiation source. The system further comprises a watchdog component communicatively coupled to the plurality of radiation-sensitive components and operable to detect radiation-induced changes in behavior of the plurality of radiation-sensitive components caused by the radiation and to determine the orientation of the flexible elongate member relative to the radiation source based on the detected radiation-induced changes in behavior. | 06-26-2014 |
20140207008 | Devices, Systems, and Methods for Visually Depicting a Vessel and Evaluating Treatment Options - Devices, systems, and methods for visually depicting a vessel and evaluating treatment options are disclosed. In some instances, a method of evaluating a vessel of a patient includes moving a second instrument longitudinally through a vessel of the patient from a first position to a second position while maintaining a first instrument in a fixed longitudinal position with respect to the vessel; obtaining pressure measurements from the first and second instruments while the second instrument is moved longitudinally through the vessel; visually depicting the vessel on a display based on the obtained pressure measurements; and modifying the visual depiction of the vessel to simulate one or more treatment options. Systems for performing such methods are also provided. | 07-24-2014 |
