摘要： A cryoablation method, system, and device that allows for real-time and accurate assessment and monitoring of PV occlusion and lesion formation without the need for expensive imaging systems and without patient exposure to radiation. The system includes a cryoballoon catheter with a cryoballoon, a distal electrode, a proximal electrode, and a temperature sensor. Impedance measurements recorded by the electrodes may be used to predict ice formation, quality of pulmonary vein occlusion, and lesion formation.

摘要： A cryotreatment catheter for treating tissue. The catheter may include an outer elongate body, a balloon treatment element coupled to the distal portion of the elongate body with a plurality of balloon lobes radially arranged around the outer elongate body, an inner elongate body rotatably movable within the lumen of the outer elongate body, and a fluid delivery lumen located within the lumen of the outer elongate body and at least partially within the lumen of the inner elongate body. The fluid delivery lumen may be branched at a distal portion into a plurality of linear segments, each linear segment being in fluid communication with one of the plurality of balloon lobes. Each of the balloon lobes may be inflated independently of each other by the linear segments of the fluid delivery lumen.

摘要： A catheter is provided comprising a flexible heat transfer element provided on an outer surface of the catheter, a conduit arranged to supply an inflation fluid for inflating the flexible heat transfer element so as to form an inflated balloon, a guide wire lumen for receiving a guide wire, and an elongate cooling element arranged to cool said inflation fluid for inflating the balloon. Said cooling element and said guide wire lumen are arranged inside the flexible heat transfer element such that, when inflated the cooling element is substantially central within the balloon and said guide wire lumen is parallel to and radially offset from the cooling element.

摘要： A cryoablation catheter for creating at least one lesion in tissue, the catheter having an elongate shaft with an intermediate section and a distal tip movable relative to the intermediate section. The catheter also includes at least one elongate control member extending along the intermediate section and secured to the distal tip where the elongate control member is movable relative to the intermediate section for causing movement of the distal tip relative to the intermediate section and at least one energy delivery member extending along the intermediate section to the distal tip where the at least one energy delivery member includes a linear first configuration and an elliptical second configuration. Manipulation of the control member adjusts the shape of the at least one energy delivery member.

摘要： Apparatus and methods for treating conditions such as rhinitis are disclosed herein where a distal end of a probe shaft is introduced through the nasal cavity where the distal end has an end effector with a first configuration having a low-profile which is shaped to manipulate tissue within the nasal cavity. The distal end may be positioned into proximity of a tissue region having a post nasal nerve associated with a middle or inferior nasal turbinate. Once suitably positioned, the distal end may be reconfigured from the first configuration to a second configuration which is shaped to contact and follow the tissue region and the post nasal nerve may then be ablated via the distal end. Ablation may be performed using various mechanisms, such as cryotherapy, and optionally under direct visualization.

摘要： Catheter apparatuses, systems, and methods for cryogenically modulating neural structures of the renal plexus by intravascular access are disclosed herein. One aspect of the present application, for example, is directed to apparatuses, systems, and methods that incorporate a catheter treatment device comprising an elongated shaft. The elongated shaft is sized and configured to deliver a cryo-applicator to a renal artery via an intravascular path. Cryogenic renal neuromodulation may be achieved via application of cryogenic temperatures to modulate neural fibers that contribute to renal function, or of vascular structures that feed or perfuse the neural fibers.

摘要： A system and method for providing greater control over the temperature of a thermal treatment element of a medical device, enabling an operator to extend a thawing period of a cryoablation procedure. The system may include a fluid flow path that bypasses a subcooler, giving the operator selective control over the temperature of refrigerant delivered to the treatment element and, therefore, treatment element temperature. Additionally or alternatively, the system may include a fluid delivery conduit that is in communication with a liquid refrigerant and a gaseous refrigerant. Adjustment of the ratio of liquid to gaseous refrigerant also offers control over the treatment element temperature. Additionally or alternatively, the system may include one or more valves and/or heating elements in the fluid delivery and recovery conduits to control the treatment element temperature.
