Abstract
A medical device is provided comprising a shaft comprising a first segment and a second segment. The first segment is configured to buckle upon application of a first critical force. The second segment includes an outer surface and an inner surface and is configured to buckle upon application of a second critical force. The second critical force is lower than the first critical force. The medical device further comprises a coil disposed radially inwardly of the inner surface of the second segment.

37. A medical device comprising:
a shaft comprising a first, proximal segment and a second, distal segment, wherein the first, proximal segment is configured to buckle upon application of a first critical force thereto; and wherein the second, distal segment is configured to buckle upon application of a second critical force thereto, wherein the second critical force is lower than the first critical force; and means for maintaining an amount of force transmitted by the second, distal segment to tissue contacting the second, distal segment after an application of the second critical force to the second, distal segment. - View Dependent Claims (38, 39)
