摘要： An example computing device includes a memory; and processing circuitry coupled to the memory, the processing circuitry being configured to: receive renal arterial anatomy information of a patient; determine one or more of a location of renal denervation therapy or a modality of renal denervation therapy to apply to the patient based on the renal arterial anatomy information; and output an indication of one or more of the determined location to apply renal denervation therapy to the patient or the determined modality of renal denervation therapy to apply to the patient.

摘要： A cryoablation catheter includes an inner lumen and an inflatable balloon surrounding the inner lumen. An inflow pipe is disposed within the inflatable balloon and is configured to introduce a refrigerant into the balloon. A thermocouple wire is disposed within the inflatable balloon and positioned adjacent the inflow pipe. The thermocouple wire is configured to measure an internal temperature of the balloon. The cryoablation catheter further includes an isolation guide disposed within the inflatable balloon. The isolation guide includes a central bore configured to receive the inner lumen, an inflow bore configured to receive the inflow pope, and a thermocouple bore configured to receive the thermocouple wire. The thermocouple bore is spaced from the inflow bore along the isolation guide.

摘要： A medical device including a proximal end portion and a distal end portion opposite the proximal end portion. An elongate shaft is disposed between the proximal and distal end portions and defines a lumen therebetween. The distal end portion includes a plurality of tubes extending from a distal end of the elongate shaft, the plurality of tubes defining a fluid pathway therein in communication with the lumen for circulation of cryogenic fluid, the plurality of tubes having a common exhaust lumen in fluid communication with the lumen.

摘要： A medical device includes an elongate shaft having an inner shaft is disposed within the elongate shaft, the inner shaft defines a first lumen defining a dedicated first port; an exhaust lumen offset from the first lumen and defining a dedicated second port; a second lumen offset from the first lumen and the exhaust lumen, the second lumen defining a dedicated third port; a third lumen offset from the first lumen, the exhaust lumen, and the second lumen, the third lumen defining a dedicated fourth port; an expandable member enclosing the dedicated first, second, third, and fourth ports. The dedicated first, second, third, and fourth ports are defined at different radial positions about the inner shaft.

摘要： A medical device includes an elongate shaft having a proximal end portion, a distal end portion, and a defining a lumen therebetween. The distal end portion defines al least one slot. An expandable member is disposed, within the lumen, the expandable member being configured to protrude outward from the at least one slot when expanded with cryogenic fluid.
