Claim 0:
1. A catheter comprising: a tube having a distal end, a proximal end, and a tube body extending between the distal end and the proximal end, the tube body having a tube wall and a first channel in the tube wall; a first elongated element located in the first channel of the tube, the first elongated element slidably moveable in the first channel relative to the tube wall; and a suction port configured to apply suction in the first channel; wherein a first part of the tube wall is configured to deform to apply a first force against the first elongated element in response to the suction in the first channel; wherein the first elongated element has a first portion that is fixed in position relative to the tube wall while a second portion of the first elongated element that is not fixed to the tube wall is slidable within the first channel; wherein a segment of the first elongated element has a center that is closer to an outer side of the tube body with a first radius of curvature than to an inner surface of the tube body with a second radius of curvature that is less than the first radius of curvature, thereby allowing the outer side of the tube body to move radially more than the inner surface of the tube body when the suction is applied in the first channel, the inner surface being radially inward with respect to the first channel and defining a central tube lumen of the tube.
