Abstract:

A catheter sensor assembly and support has a member with a distal end and a proximal extension joined by an intermediate part. An open passage extends along the proximal extension and across the intermediate part to carry a sensor overlaying the passage. Conductors attach to the sensor bottom for transmitting signals from the sensor through a catheter lumen. An adhesive sealant secures the sensor to the intermediate part near the distal end so that the passage remains open between the lumen and the bottom. A method for assembling and supporting a sensor at a distal end of a catheter tube includes steps of attaching a sensor with an area toward an end connected to electrical conductors, placing a tube in the passage to provide a passageway between the lumen and the sensor, mounting the sensor to the member overlying the passage, inserting the proximal extension into the lumen with the electrical conductors passing through the lumen and sealing the sensor to the passage.
