摘要： A medical device including an ablation element. A thermally insulative sheath is included disposed within the ablation element. A fluid injection tube is disposed within a portion of the thermally insulative sheath. The ablation element passively transitions from a substantially linear geometric configuration to a substantially circular geometric configuration as the sheath is retracted proximally from a first position in which the sheath substantially encloses the fluid injection tube to a second position in which a portion of the fluid injection tube extends a distance away from the sheath.

摘要： Systems and methods for controllably variable fluid flow are disclosed that provide the ability to modify the effective cross-sectional area of the fluid delivery conduit available for fluid flow. Accordingly, selective control of these configurations allows fluid flow to be regulated as desired while the fluid delivery pressure remains the same. Additional configurations provided herein allow for the selective manipulation of a footprint or therapeutic pattern achievable with the medical device during a single procedure, negating the need for the removal and insertion of multiple devices to achieve the same variations in treatment geometry or characteristics.
