Aesthetic method of biological structure treatment by magnetic field
In combined methods for treating a patient using time-varying magnetic field, treatment methods combine various approaches for aesthetic treatment. A magnetic field generating device is placed proximate to a body region of the patient. The magnetic field generating device generates a time-varying magnetic field with a magnetic flux density in a range of 0.5 to 7 Tesla. The time-varying magnetic field is applied to the body region of the patient in order to cause a contraction of a muscle within the body region. A second therapy may be used by applying one or more of optical waves, radio frequency waves, mechanical waves, negative or positive pressure or heat to the body region of the patient.
Methods and system of temperature based alarms and/or automatic interrupt (shut-off) in fluoroscopy (medical images) based mapping system for cryoballoon ablations or radiofrequency (RF) ablations for atrial fibrillation
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.
THERAPEUTIC TOOTH BUD ABLATION
Ablation probe tips (108, 148, 320, 360) and physical and virtual stents (110) for use in tooth bud ablation procedures that result in tooth agenesis as well as tooth bud ablation methods are described herein.
Ablation system, methods, and controllers
Multi-electrode ablation systems, methods, and controllers are described. In one example, a method of beginning an ablation procedure using a multi-electrode ablation system is described. The method includes selectively coupling the output of a power supply to a first electrode of a plurality of electrodes to increase a temperature at the first electrode to a first temperature set-point and limit a rate of increase of the temperature at the first electrode to a predetermined first rate.
Real-time estimation of tissue perforation risk during minimally invasive medical procedure
A method for performing a medical procedure, includes coupling a tip of a probe to tissue in an organ of a patient in order to apply the medical procedure using the probe. A force exerted by the tip on the tissue and a displacement of the tip created by the force are measured. A dependence of the force on the displacement is calculated. Based on the calculated dependence, a risk level of perforation of the tissue is estimated.
FLEXIBLE CIRCUITS FOR ELECTROSURGICAL INSTRUMENT
The disclosure provides a method of manufacturing a flexible circuit electrode assembly and an apparatus manufactured by said method. According to the method, an electrically conductive sheet is laminated to an electrically insulative sheet. An electrode is formed on the electrically conductive sheet. An electrically insulative layer is formed on a tissue contacting surface of the electrode. The individual electrodes are separated from the laminated electrically insulative sheet and the electrically conductive sheet. In another method, a flexible circuit is vacuum formed to create a desired profile. The vacuum formed flexible circuit is trimmed. The trimmed vacuum formed flexible circuit is attached to a jaw member of a clamp jaw assembly.
SMART POWER SELECTION FOR MULTI-ELECTRODE RF ABLATION SYSTEM
A computing device for generating and using a graphical user interface (GUI) is disclosed. The computing device includes one or more controllers configured to generate a graphical representation of a plurality of electrodes of an ablation catheter for displaying via the GUI; designate, via the GUI, at least some of the plurality of electrodes to be active electrodes; automatically designate the active electrodes as a source electrode or a sink electrode; assign an amount of energy to each of the designated source electrodes; and estimate an amount of energy associated with each of the designated sink electrodes based at least in part on the assigned energy of the designated source electrodes.
CAUTIOUS IRREVERSIBLE-ELECTROPORATION (IRE) PROTOCOL FOR AVOIDING BUBBLE GENERATION
An irreversible electroporation (IRE) includes setting an initial IRE protocol for applying IRE pulses by electrodes of a catheter placed in contact with tissue in an organ. A notification is issued to a user upon determining that the initial IRE protocol is expected to cause bubbles in blood. In response to the notification, user input is received from the user, that selects between the initial IRE protocol and an alternative protocol that is not expected to cause the bubbles. The IRE pulses are applied according to the initial IRE protocol or the alternative IRE protocol, depending on the user input.
Probe system and a probe for measuring functionality of an orifice in the human pelvic region
For measuring functionality of an orifice (16, 20) in the human pelvic region an elongated probe (4; 54) for insertion in the orifice (16, 20) is provided. The probe (4; 54) comprises one or more electrodes (5a-6a, 5b-6b, 6a-7a, 6b-7b; 55a-56a, 55b-56b, 56a-57a, 56b-57b, 57a-92a, 57b-92b) for stimulating receptors (23, 25) in tissue bounding the orifice (16, 20) and one or more muscle activity sensors (8a, 8b, 8c, 9a, 9b, 9c, 10a, 10b, 10c, 10d, 11a, 11b, 11e, 12a, 12b, 12c; 58a, 58b, 58c, 59a, 59b, 59c, 60a, 60b, 60c, 60d, 61a, 61b, 61c, 62) for sensing muscle activity causing pressure to be exerted by tissue bounding the orifice (16, 20). A control system (I) connected to the probe (4; 54) is arranged for outputting a neurostimulation signal (35) to the electrode or electrodes and for registering a pressure signal or signals from the pressure sensor or sensors during a time interval directly subsequent to the outputting of the neurostimulation signal.
RECOVERY SYSTEM FOR N20
A system for the recovery of expanded refrigerant from a cryotreatment system for storage and disposal may generally include first fluid flow path having a first compressor and a fluid recovery reservoir, and a closed-loop second fluid flow path having a thermal exchange device that is in thermal communication with the fluid recovery reservoir, a second compressor, and a condenser. The first fluid flow path may include a primary refrigerant from a cryotreatment system and the closed-loop second fluid flow path may contain a secondary refrigerant for cooling the primary refrigerant within the fluid recovery reservoir. The refrigerant recovery conduit may be in fluid communication with both the cryotreatment system and a medical facility scavenging system. The refrigerant recovery conduit and the cryotreatment system may be located within the same cryotreatment console.
