  • Patent number: 10485602
    Abstract: A cryosurgical apparatus with a temperature regulator. For better therapeutic success, it is desirable to set the temperature applied to a cryosurgical instrument as exactly as possible. Conventional apparatuses have corresponding temperature sensors allowing the regulation of the cooling power in the cryosurgical instrument such that the cooling power corresponds to a predefined value. However, the dimensions of some temperature sensors prevent them from being provided within a cryoprobe. Furthermore, suitable temperature sensors are expensive and have low durability. This problem is solved by the disclosed temperature regulator for regulating the temperature of a cryoprobe, which supplies an at least partly liquid refrigerant at a first pressure to an evaporation region such that the coolant evaporates at least temporarily under the presence of a second pressure for cooling a cooling portion of the cryoprobe. A pressure setting means that sets at least the second pressure is also provided.

  • Patent number: 9918790
    Abstract: An apparatus and methods for performing ablation of myocardial tissues are disclosed. The apparatus includes a plurality of ablation electrode configurations to which nanosecond pulsed electric fields are applied. The methods relate to therapies to treat cardiac arrhythmias, such as, atrial fibrillation and scar-related ventricular tachycardia, amongst others. The affected myocardial tissues are ablated creating a plurality of lesions enabled by the nanosecond pulsed electric fields applied to either penetrating electrodes, endo-endo electrodes, or endo-epi electrodes. Different electrophysiological tests are performed to assess the application of nanosecond pulsed electric field ablation to specific desired tissue location within the heart. Test results show the potential to overcome limitations of current ablation therapies, thereby providing patients and doctors a superior treatment for cardiac arrhythmias.

  • Patent number: 9820802
    Abstract: A method and system for increasing safety of cardiac ablation procedures comprises a computer based system that monitors the esophageal temperature, and a fluoroscopy (medical images) based cardiac mapping system for cryoballoon or radiofrequency (RF) ablations. The esophageal temperature is monitored utilizing an esophageal probe which may have any number of temperature sensing members. The esophageal probe may also have pre-formed shape. During atrial fibrillation ablations, based on a pre-determined increase in esophageal temperature (from any thermistor), the computer based system activates different levels of alarm(s), and/or initiates ablation energy interrupt based on pre-defined programmed values. The method and system is also used for guiding placement of cryoballoon and performing cryoablations. The placement of cryoballoon catheter or a circular catheter is based on superimposing a high resolution (dye injected) image and a live fluoroscopy image and adjusting transparency between the two images.
