Disclosed herein is a system for ablating and characterizing tissue. The system comprises an ablation element configured to emit ablative energy toward a tissue of interest, an imaging apparatus configured to emit energy and collect imaging data including reflected signals from the tissue of interest, and a characterization application. The characterization application comprises a signal analyzer for analyzing the imaging data and determining one or more signal properties from the reflected signals, and a correlation processor configured to associate the one or more signal properties to pre-determined tissue signal properties of different tissue components through a pattern recognition technique. The pre-determined tissue signal properties are embodied in a database, and the correlation processor is configured to identify a tissue component and an ablation level of the tissue of interest based on the pattern recognition technique.

Temperature uncertainty maps are calculated based on a rolling window of temperature maps, which is updated as new temperature maps are generated. The rolling window mitigates the effect of transient motion during a thermal therapy procedure. A clinician or an automated control system can then update a portion of an anatomical boundary or the thermal therapy applicator center based on the temperature uncertainty map.

The present invention relates to an ultrasound treatment device for HIFU and an ultrasound image, and to a control method therefor. The ultrasound treatment device comprises: a plurality of image converters disposed on one surface of a probe assembly to transmit ultrasound signals to a target and receive signals reflected by the target to create an ultrasound image; a plurality of high intensity focused ultrasound (HIFU) converters disposed on the surface of the probe assembly so as to be located in different positions from the image converters, wherein the HIFU converters transmit ultrasound signals to a target to generate heat energy, thereby treating a tissue within a focusing area; and a control unit performing control such that the difference between apertures of converter arrays constituted by the image converters and the HIFU converters, respectively, is less than a predetermined value.

Devices, systems, and methods relating to a low-voltage, pre-treatment pulse routine for evaluating a potential for non-target tissue damage from the delivery of energy, such as electroporation energy to an area of target tissue. In one embodiment, a medical system includes a medical device having a treatment element; and a control unit in communication with the medical device, the control unit being configured to: deliver a low-voltage, pre-treatment pulse routine through the treatment element to an area of target tissue; determine whether the low-voltage, pre-treatment pulse routine has a stimulation effect on an area of non-target tissue; and deliver an ablation energy routine through the treatment element to the area of target tissue when the control unit determines that the low-voltage, pre-treatment pulse routine does not have a stimulation effect on the area of non-target tissue.

The present invention relates to a portable HIFU skin care device. The portable HIFU skin care device (1) of the present invention is divided into three portions. Firstly, a main body (100) has a rechargeable battery embedded therein, a power button and a step button installed therein for adjusting the intensity of an ultrasonic wave, and a display for displaying the operation states of the device, including the number of shots. In addition, a cartridge (200) is used by being mounted on a head part of the main body (100) and has a HIFU transducer embedded therein. A cradle (300) has a charging part which is installed therein, is capable of charging by being connected with the cartridge (200) and an adaptor, accommodates the main body (100) through a placement groove while the cartridge (200) is mounted to the main body (100), includes a UV lamp for disinfecting the head part of the cartridge (200) when accommodating the main body (100), and charges an internal battery of the main body (100). In an operation state, while the HIFU transducer is linearly moved for each one shot by a piezoelectric motor, a plurality of ultrasonic waves are emitted so as to form a plurality of ultrasonic focal point regions on an object, thereby achieving a skin care effect. In the present invention, the piezoelectric motor (216) is particularly installed inside the cartridge (200).

An endorectal cooling device (ECD) includes an elongated body, a cooling fluid circuit, and a gas bubble removal device. The elongated body includes an insertable portion for insertion into a patient's rectum and an external portion that remains external to the rectum. The cooling fluid circuit is defined in the elongated body from the external portion to the insertable portion and circulates cooling fluid to regulate a temperature of a cooling surface on the insertable portion. The gas bubble removal device can include a coil, a tube, a mesh, and/or a hole that is disposed on or defined in the insertable portion of the elongated body, such as the cooling surface. A low-pressure source, such as a vacuum pump or a Venturi structure, can be fluidly coupled to the gas bubble removal device to remove fluid and bubbles by a suction force after the ECD is inserted into the rectum.
