摘要： A method for determining a predicted lesion size formed in a tissue by receiving or calculating a measure of contact force between the electrode and the tissue, determining a tissue characterization, and calculating the predicted lesion size using both the measure of contact force and the tissue characterization. A system comprising an electronic control unit configured to receive or determine a measure of contact force between the electrode and the tissue, characterize the tissue based on both the measure of impedance and the measure of contact force, and cause the tissue characterization to be either (a) presented to a user, or (b) applied to calculate a metric and cause the metric to be presented to the user.

摘要： A monitoring system may include a processor and display system for displaying results from the monitoring. A user may be in a sterile field away from the processor and display system and selected input devices. A controller may be physically connected to the monitoring system from the sterile field to allow the user to control the monitoring system.

摘要： A laser system may include a controller configured to direct a plurality of temporally spaced-apart electrical pulses to a device that optically pumps a lasing medium, and a lasing medium configured to output a quasi-continuous laser pulse in response to the optical pumping. The plurality of temporally spaced-apart electrical pulses may include (a) a first electrical pulse configured to excite the lasing medium to an energy level below a lasing threshold of the lasing medium, and (b) multiple second electrical pulses following the first electrical pulse. The quasi-continuous laser pulse is output in response to the multiple second electrical pulses.

摘要： A system to treat a patient comprises a user interface that allows a physician to view an image of tissue to be treated in order to develop a treatment plan to resect tissue with a predefined removal profile. The image may comprise a plurality of images, and the planned treatment is shown on the images. The treatment probe may comprise an anchor, and the image shown on the screen may have a reference image marker shown on the screen corresponding to the anchor. The planned tissue removal profile can be displayed and scaled to the image of the target tissue of an organ such as the prostate, and the physician can adjust the treatment profile based on the scaled images to provide a treatment profile in three dimensions. The images shown on the display may comprise segmented images of the patient with treatment plan overlaid on the images.

摘要： Devices and methods are provided for treatment of tissue in a body lumen with an electrode deployment device. Embodiments typically include a device with a plurality of electrodes having a pre-selected electrode density arranged on the surface of a support. The support may comprise a non-distensible electrode backing that is spirally furled about an axis and coupled to an expansion member such as an inflatable elastic balloon. In some embodiments, the balloon is inflated to selectively expose a portion of the electrode surface while maintaining the electrode density.

摘要： A surgical image acquisition system includes multiple illumination sources, each source emitting light at a specified wavelength, a light sensor to receive light reflected from a tissue sample illuminated by each of the illumination sources, and a computing system. The computing system may receive data from the light sensor when the tissue sample is illuminated by the illumination sources, and calculate structural data related to one or more characteristics of a structure within the tissue. The structural data may be a surface characteristic such as a surface roughness or a structure composition such as a collagen and elastin composition. The computer system may further transmit the structural data to a smart surgical device. The smart devices may include a smart stapler, a smart RF sealing device, or a smart ultrasonic cutting device. The system may include a controller and computer enabled instructions to accomplish the above.

摘要： Devices and methods for fluid enhanced ablation therapy using microwave antennas are described herein that provide improved heat transfer into a target volume of tissue and improved antenna cooling compared to prior art designs. In one embodiment, fluid can be introduced into a target volume of tissue along with the delivery of therapeutic energy from a microwave antenna positioned within the target volume of tissue. The fluid can become heated by cooling the microwave antenna and, if additional heating of the fluid is desired, a heating element disposed within the microwave antenna can supplementally heat the fluid prior to introduction into the target volume of tissue.
