A device comprising: (a) one or more markers, some or all of which are expandable rounded members that are expandable from a stored state to an expanded state and when in the expanded state each of the expandable rounded members expand to move into contact with a lumen in an organ; and (b) one or more tissue tags connected to the expandable rounded members or the expandable rounded members being made of a magnetized material; and wherein the expandable rounded members are configured to be located within and deployed from an insertion mechanism into the lumen in the organ.

The present invention is directed to a system for delivering radiofrequency ablation energy to an area or volume of tissue. The system includes a wrap, where a stiffening element surrounds an opening in the wrap, where the stiffening element transfers radial compression to the area or volume of tissue, where the radial compression increases stability of the area or volume of tissue; and at least one radiofrequency ablation probe having an active electrode, where the at least one radiofrequency ablation probe is connected to a radiofrequency generator via a lead. A device that includes a wrap and a method of delivering radiofrequency ablation energy to a volume of tissue via the device are also described.

A laser surgical method for performing a corneal incision while maintaining iris exposure below a predetermined exposure limit includes: determining an initial iris exposure based on an initial treatment scan, determining whether the initial iris exposure is less than the predetermined exposure limit; generating a revised treatment scan comprising one or more treatment scan modifying elements when the initial iris exposure is greater than the predetermined exposure limit, and scanning the focal zone of a pulsed laser beam according to the revised treatment scan, thereby performing the corneal incision, wherein the one or more treatment scan modifying elements causes the iris exposure to be smaller than the predetermined exposure limit.

Methods and systems for distributing electrical energy to tissue which minimize Joule heating, thermal effects, and/or thermal damage, without sacrificing efficacy of treatment, are described. The methods and systems are particularly suitable to electrical energy-based therapies employing multiple electrodes, such as arrays of electrodes.

A handheld device includes an electronic instrument and a capacitive power supply for storing and delivering power to the electronic instrument. The capacitive power supply includes at least one capacitor, and an electronic circuit operable to boost a voltage from the capacitor to a higher voltage for use by the electronic instrument. The capacitive power supply can be rapidly recharged. Some configurations include an accelerometer which permits the handheld device to detect movement and perform various operations responsive to detected movement. A dual charging station is also disclosed.

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.
