摘要： A catheter includes a segment having a longitudinal axis. The segment includes a polymeric tube having interior and exterior surfaces separated by a wall thickness. The interior surface defines a catheter lumen which extends coaxially with the longitudinal axis. The exterior surface is sized for the tube to be passed through a patient's vasculature system. The segment further includes a substantially straight, flexible guide member disposed within the tube's wall thickness. The guide member has a longitudinal dimension extending parallel to and radially spaced from the segment's axis. The guide member is plastically deformable when bent around a bending axis perpendicular to the longitudinal dimension beyond a bending limit.

摘要： The device and method for reducing heart wall stress. The device can be one which reduces wall stress throughout the cardiac cycle or only a portion of the cardiac cycle. The device can be configured to begin to engage, to reduce wall stress during diastolic filling, or begin to engage to reduce wall stress during systolic contraction. Furthermore, the device can be configured to include at least two elements, one of which engages full cycle and the other which engages only during a portion of the cardiac cycle.
