  • Publication number: 20190209230
    Abstract: 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.

  • Publication number: 20180214045
    Abstract: A device and system for providing mapping and treatment capabilities without increasing stiffness of the device. An embodiment of a device may include a flexible elongate body and at least one mapping element on the distal portion of the elongate body. Each mapping element may be an area of thermally conductive material, such as metallic nanoparticles, that is embedded within, integrated with, or deposited on the elongate body. The flexibility of the areas of thermally conductive material is at least substantially the same as that of the elongate body so the device may include many electrodes without compromising flexibility and maneuverability of the device. Alternatively, the device may include a treatment element coupled to the elongate body, such as a balloon. The mapping elements may be embedded within, integrated with, or deposited on the balloon and may have at least substantially the same flexibility as that of the balloon.

  • Patent number: 9730755
    Abstract: A system and method for the delivery of a medical device to a treatment location. The device may include an elongate body, the elongate body including a plurality of annular segments and a jacket disposed about the plurality of annular segments and defining an interior space, and a vacuum source in fluid communication with the interior space of the jacket. When a vacuum is applied to the interior space of the jacket, the jacket may constrict about the plurality of annular elements, thereby increasing the frictional forces between the plurality of segments and between the plurality of segments and an inner surface of the jacket.

  • Patent number: 9345528
    Abstract: 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.

  • Publication number: 20150196740
    Abstract: A system and method for creating radial-linear lesions in tissue. The system includes a cryoablation device having a first balloon, a second balloon disposed about the first balloon, and one or more splines disposed between the first balloon and second balloon, each spline defining a plurality of ports. The splines may be in communication with a coolant supply, and the first balloon may be in communication with a coolant supply or non-coolant inflation fluid supply. When the first balloon is in the uninflated configuration, the splines may have a substantially linear configuration. Each of the splines may be radially oriented about an elongate shaft and transitionable between the substantially linear configuration and an arcuate configuration when the first balloon is in the inflated configuration. Coolant expelled from the splines between the first and second balloons creates an ablation pattern on the outer surface of the second balloon.

The thermally-transmissive region may include a plurality of interconnected thermally-transmissive segments that are generally cylindrical in shape. The cryogenic catheter may be in fluid communication with a fluid source, and may include one or more fluid injection tubes. Further, an injection tube may be slidably disposed within the catheter so that the injection tube is longitudinally movable relative to an outer surface of the catheter. The cryogenic catheter may also be in communication with a controller programmed to regulate delivery of a cryogenic fluid from the fluid source to the medical device.
