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.

摘要： A medical device is provided that may include a catheter body having proximal and distal portions, a fluid injection lumen disposed within elongate body, and a guidewire lumen disposed within the elongate body. A tip portion defining a cavity in fluid communication with the fluid injection lumen may be coupled to the distal end of the guidewire lumen, and an expandable element may be coupled to the distal portion of the catheter body and to the tip portion, such that the expandable element is in fluid communication with the fluid injection lumen. A shaping element may at least partially surround the expandable element, where the shaping element is configurable in a first geometric configuration and a second geometric configuration.

摘要： A medical device includes a catheter body having a first injection lumen, a second injection lumen, and an exhaust lumen, where the first injection lumen provides a fluid flow rate greater than a fluid flow rate provided by the second injection lumen; an expandable element coupled to the catheter body in fluid communication with the first and second injection lumens; a cryogenic fluid source in fluid communication with the first and second injection lumens; a valve in fluid communication with the first and second injection lumens to selectively allow fluid flow to at least one of the first and second injection lumens; a pressure sensor in fluid communication with an interior defined by the expandable element; and a controller in communication with the pressure sensor programmed to regulate fluid flow through the first injection lumen based at least in part on a signal from the pressure sensor.
