ENDOLUMINAL OSTIUM SENSOR ARRAY DEVICE

摘要

A sensor device for sensing endoluminal geometry may include an expandable element disposed on the distal region of a shaft. The expandable element may be configured to move a collapsed configuration and an expanded configuration. The expandable element may include one or more sensor elements configured to sense proximity of the sensor element to tissue. The sensor device may include an indicator configured to distinguish between contact of the sensor element with tissue, loss of contact and proximity of the sensor element to tissue.
