Abstract
Medical or surgical instrument, such as a catheter, micro-catheter, guide-wire, cannula, blade, and forceps, comprising one or more sensors to allow measurement of parameters around or within the instrument, and methods for making and using the same, are disclosed. Also disclosed are methods and apparatuses for measuring fluid characteristics, such as blood characteristics, including, for example, velocity, flow direction, and pressure in a vascular system.
Claims30
A device for measuring blood flow in a blood vessel, comprising
- a catheter having a curved outer surface;
- and
- at least one conformal blood flow sensor on the curved outer surface, wherein the at least one blood flow sensor is configured to measure the blood flow.
A medical or surgical device, comprising:
- a portion comprising a curved outer surface configured for at least one medical or surgical application;
