Abstract: Ablation systems and methods include an improved approach to generating heated vapor. The vapor ablation system preferably has a controller having a user interface that receives data indicative of a time of a treatment session, a pump in data communication with the controller, and a catheter having an electrode and is in fluid communication with the pump. The controller is configured to control the pump to provide a fluid to the lumen of the catheter, cause an electrical current to be delivered to the electrode in order to heat the fluid in the lumen and convert the fluid to a heated vapor, control a delivery of the fluid and a generation of the heated vapor based on the data indicative of the time and without modifying the flow rate of the fluid or the level of voltage and/or current of the electrical current based on data from sensors positioned in or on the catheter.

Abstract: Systems and methods for laser catheter treatment in a vessel lumen. The method includes inserting the laser catheter within the vessel lumen to a location of a treatment area; presenting an image of the treatment area within the vessel lumen based on using an ultrasound (US) imaging system; and, detecting, in real-time, a bubble cloud that is a function of the laser catheter operation (at a prescribed speed and controlling a fluence and a pulse rate) in the treatment area. The method determines a vessel diameter, a real-time location and measurements of the bubble cloud, and estimates a dwell position and dwell time. A dynamic displayed image that is indicative of a progression of the laser catheter treatment is presented, and commands may be generated to modify the laser catheter parameters responsive to the estimated dwell position, the estimated dwell time, and a recommended treatment protocol.

Abstract: Systems and methods for protecting non-target tissue from damage during a medical procedure for disrupting target tissue via heat application are disclosed. Data associated with the target tissue to be disrupted may be received. Based on the received data, one or more non-target objects of tissue that may be affected by the applied heat are identified. Both a temperature threshold and thermal dose threshold for each of the one or more non-target objects may be generated. Both the temperature and the thermal dose of each of the one or more non-target objects may be evaluated during performance of the medical procedure. A response may be generated when either the evaluated temperature of any of the one or more non-target objects reaches the corresponding temperature threshold or the thermal dose of any of the one or more non-target objects reaches the corresponding thermal dose threshold.

Abstract: Devices and systems used to ablate tissue of a tumor using laser energy are disclosed. The devices and systems include a laser probe and a magnetic resonance (MR) safe temperature probe. The MR safe temperature probe includes an optical sensor. A bone anchor fixture separates the laser probe and the MR safe temperature probe to prevent interference in the MR safe temperature probe data. Proton Resonance Frequency (PRF) thermometry is used to model a temperature of a pixel of an MR image located adjacent the optical sensor. The modeled pixel temperature and the measured temperature are compared and monitored. Exceeding a threshold difference value causes an intervening action to occur.

Abstract: A catheter system (100) for treating a treatment site (106) within or adjacent to the vessel wall of a blood vessel (108), or the heart valve, includes an energy source (124), a balloon (104), an energy guide (122A), and a balloon integrity protection system (142). The energy source (124) generates energy, The balloon (104) is positionable substantially adjacent to the treatment site (106). The balloon (104) has a balloon wall (130) that defines a balloon interior (146). The balloon (104) is configured to retain a balloon fluid (132) within the balloon interior (146). The energy guide (122A) is configured to receive energy from the energy source (124) and guide the energy into the balloon interior (146) so that plasma is formed in the balloon fluid (132) within the balloon interior (146). The balloon integrity protection system (142) is operatively coupled to the balloon (104). The balloon integrity protection system (142) is configured to inhibit rupture of the balloon (104) due to the plasma formed in the balloon fluid (132) within the balloon interior (146) during use of the catheter system (100).
