摘要:
A medical treatment device (10) having an adjustable length and /or diameter is disclosed. The medical treatment device (10) comprises: a catheter having an elongate flexible shaft (12) with a proximal end (14) and a distal end (13); a first electrically resistive heating element (92) having a first outer diameter and disposed at the distal end (13) of the shaft (12); first electrical contacts (98) on the catheter shaft (12); a second electrically resistive heating element (100) having a second, lager, outer diameter and connectable to the shaft to at least partially surround the first electrically resistive heating element (92) and having second electrical contacts (102) connectable to the first electrical contacts (92). The device enables the length and /or diameter of the heating segment to be adjusted during a treatment procedure without a need to interrupt the procedure and thereby allows a single catheter to be used at different location in a hollow anatomical structure.
