Abstract
An adjustable profile probe for insertion in a body cavity to sense a biological parameter includes an elongated shaft having a sensor panel and a resiliently expandable portion substantially opposing the sensor panel. An expansion mechanism is at least partially housed within the elongated shaft for varying the profile of the probe. The expansion mechanism includes a base plate adjacent to the resiliently expandable portion and a plurality of lever arms pivotally mounted to the base plate and the sensor panel. An actuating member pivotally connects to the lever arms such that upon movement of the actuating member, the resiliently expandable portion is selectively collapsed or expanded by the plurality of lever arms pivoting between a minimal profile position near parallel with the elongated shaft and an expanded profile position with the lever arms being near perpendicular to the elongated shaft.
