A therapeutic ultrasound breast treatment device (101) is disclosed. The device (101) can include a receptacle (130) to receive a breast of a patient therein. The device (101) can also include an ultrasound transducer assembly disposed proximate the receptacle and oriented to direct a high intensity ultrasound transmission through an opening (168) of the receptacle (130) toward the breast. The device (101) can include a liner (1 60) disposed in the receptacle (130) to contain an ultrasound coupling fluid about the breast. The liner (160) can have an extension portion that extends through the opening (168) to form a seal with the ultrasound transducer assembly to prevent leakage of the ultrasound coupling fluid. A focus location of the ultrasound transmission can be adjustable and the device (101) can include a plurality of RF tracking coils to determine the focus location of the ultrasound transmission to facilitate adjustment of the focus location in an MRI environment.

An intracorporeal pressure shock wave includes an expandable pressure shock wave reflector at the distal end of an intracorporeal catheter to direct shock waves from a shock wave generator within a human or animal blood vessel or body lumen.

Acoustic signal transmission couplants for use in tomographic, large aperture ultrasound imaging and therapeutic ultrasound are described that couple acoustic signal transducers to body structures for transmitting and receiving acoustic signals. The acoustic signal transmission couplants can conform to the receiving medium (e.g., skin) of the subject such that there is an acoustic impedance matching between the receiving medium and the transducer. In one aspect, an acoustic coupling medium includes a hydrogel including polymerizable material that form a network structured to entrap an aqueous fluid inside the hydrogel. The hydrogel is structured to conform to the receiving body, and the acoustic coupling medium is operable to conduct acoustic signals between acoustic signal transducer elements and a receiving medium when the hydrogel is in contact with the receiving body such that there is an acoustic impedance matching between the receiving medium and the acoustic signal transducer elements.

A warming device and system for warming medical gel to a comfortable temperature prior to application to a patient. A warming chamber configured to receive one or more gel containers (e.g., packets or bottles) disposed in a horizontal orientation with a cover sealing the chamber. Multiple protrusions and/or depressions disposed on an inside surface of the chamber can be used to soften thermal conduction of heat to the gel containers and inhibit hot spots. A flexible heating element and an intermediate thermal conducting member can extend up one or more sides of the warming chamber. Multiple buttons can be used to set different gel temperature settings.

Devices and methods for treating human cranial hair loss using extracorporeal acoustic shock waves are disclosed. The shock wave device optionally includes a proximal surface, a plurality of shock wave generators disposed on the surface, and a coupling assembly configured to transmit shock waves to a user's scalp.

An ultrasound gel is provided for use with internal ultrasound imaging and/or therapy. The gel can have acoustic properties that can closely match a soft tissue to be imaged/treated and can be of a high viscosity that is maintained at body temperature. In some embodiments, the gel can act as a lubricant and, although water based, can be hydrophobic and not dissolve in bodily fluids. In some embodiments, the gel can be sterile, safe for ingestion, safe for application over mucous membranes, and include a preservative. In order to achieve sterility while maintaining a desired viscosity range, the gel can include a viscosity stabilising agent such as a viscosity protection agent for protection from radiation induced breakdown. In some embodiments, methods of altering or maintaining the viscosity of a gel is provided.

A method of treating vaginal tissue atrophy in a female subject, the method including the steps of engaging an energy delivery element with tissue in or around the subject's vagina; applying energy to the tissue from the energy delivery element; and increasing blood flow to internal vaginal tissue to an increased level above a baseline level of blood flow to the internal vaginal tissue, the increased level of blood flow to the internal vaginal tissue persisting after the applying step ceases. The invention also provides devices for performing this therapy.

Arrangements described herein relate to systems, apparatuses, and methods for managing gel on a subject to provide gel on a first area of the subject, including controlling a transducer to move to a second area of the subject and controlling the transducer to move the gel to the first area from the second area.

An intracorporeal pressure shock wave device to provide treatment within blood vessels artificial vessels and grafts that includes a frontal pressure shock wave reflector positioned at the distal end of an intracorporeal catheter to direct shock waves toward a treatment target, such as an occlusion and clot.
