Abstract: Medical devices and methods for using medical devices are disclosed. An example medical device includes a catheter having a proximal end region and a distal tip and an array of sealed chambers disposed along the distal tip, wherein each of the chambers includes a distal membrane disposed along an outer surface of the distal tip and a proximal membrane extending radially inward from the outer surface. Further, each proximal membrane is configured to shift between a first position and an expanded position in response to a change in pressure within the chamber.
