Systems and methods for treating skin and subcutaneous tissue with energy such as ultrasound energy are disclosed. In various embodiments, ultrasound energy is applied at a region of interest to affect tissue by cutting, ablating, micro-ablating, coagulating, or otherwise affecting the subcutaneous tissue to conduct numerous procedures that are traditionally done invasively in a non-invasive manner. Lifting sagging tissue on a face, neck, and/or body are described. Treatment with heat is provided in several embodiments.

The present invention relates to a device for transport and preservation of an ex vivo biological sample and corresponding method. The device (1) comprises a chamber (2) for containing the biological sample (100), delimitated by walls (4) made of a thermal insulating material. The device, furthermore, incorporates cooling means (6) that keep the temperature inside the chamber (2) below the temperature outside the device (1). Finally, an ultrasound system suitable for generating and applying ultrasound on the biological sample (100) is provided. The invention also proposes a method for transport and preservation which combines applying cooling and ultrasound to reduce cell damage in the biological sample.

An ultrasonic surgical instrument including a blade that treats tissue and a fluid control system to cool the blade by pumping cooling fluid through the blade. The blade defines a blade lumen in fluid contact with an inflow and return conduit of the fluid control system. The inflow conduit defines an open distal end positioned within the blade lumen adjacent the distal end of the blade lumen and the return conduit defines an open distal end positioned within the blade lumen adjacent the proximal end of the blade lumen. The fluid control system may further include a fluid reservoir holding the cooling fluid and an inflow pump. The inflow pump is configured to deliver the fluid from the fluid reservoir, through the inflow conduit and the blade lumen, and into return conduit.

A device is provided for the stimulation of neurons that includes a non-invasive stimulation unit to generate stimuli in multiple stimulation channels, where the stimulation unit stimulates a neuron population in the brain and/or spinal cord of a patient in different locations for each of the stimulation channels. Moreover, the device includes a control unit that controls the stimulation unit to generate repetitive bursts in each of the stimulation channels, where each of the bursts includes multiple stimuli and is designed so that they do not reset the phase of the neuronal activity of the respective stimulated neurons.

An apparatus and method for automatically lysing a clot to recanalize vessels using ultrasound, with or without nanoparticles, microbubbles, thrombolytic drugs or other agents, is described herein. At least one ultrasound transducer with a specified geometry, bandwidth and/or transmit pulse characteristics can generate a more uniform 3-dimensional volume of defocused acoustic energy into a target area of the body. When an agent (such as, but not limited to, microbubbles) is used to lyse a clot, a certain level of ultrasound energy may be desired in order to effect certain actions or states of the agent. Bone attenuation may present an issue inhibiting sufficient ultrasound energy from reaching the agent in order to attain the desired agent action. The relative patient dimensions and location of the clot may also present an issue.
