Improved devices, systems, and methods for inhibiting hyperplasia in blood vessels provide controlled and safe cryotherapy treatment of a target portion within a body lumen of a patient. Efficacy of endoluminal cryogenic cooling can be enhanced by limiting cooling of target tissues using a thermal barrier disposed between a dual balloon cryotherapy catheter. Containment of both balloons can be monitored by applying a vacuum within a space between the first and second balloons, and by coupling the vacuum space to a fluid shutoff so as to inhibit flow of cryogenic fluid in response to a change in the vacuum space. Controlled cooling of the vessel can be improved by use of a nebulizer in fluid communication with a cryogenic liquid supply lumen and a gas supply lumen.

Methods and devices for enhanced ultrasound detection based upon changing temperature and ultrasound reflectivity of a temperature-dependent contrast agent bound to an ultrasound target are disclosed. The methods and devices can be used for enhanced imaging alone or in conjunction with drug delivery, with therapeutic approaches such as hyperthermia or cryotherapy or with other imaging modalities.

A gas-based cryotherapy probe is provided with a shaft having a closed distal end adapted for insertion into a body. A supply conduit is disposed longitudinally within the shaft for flowing gas towards the distal end, and a return conduit is disposed longitudinally within the shaft for flowing gas from the distal end. The gas is maintained at a lower pressure within the return conduit than in the supply conduit. A heat exchanger is disposed within the shaft in thermal communication with the supply conduit and return conduit to exchange heat from gas in the supply conduit to gas in the return conduit. A vacuum jacket is adapted to provide thermal isolation of the heat exchanger from the shaft.

The invention relates to a new dispensing device for pressurized containers of coolants for cryotherapy, with a manual opening/closing valve, which includes a dispenser body suited to be permanently fixed to said container, a valve-opening element and a cap with teeth resting against said valve-opening element to cause the opening of the valve. In one embodiment, at least one tube or duct for application of the coolant, at one end of which at least one applicator pad or filter is partially and removably inserted, is permanently built in and integral with said dispenser body.

The invention relates to a cryotherapy system through natural orifice of human body, which comprises a flexible cryoprobe, a frozen host, and a gas cylinder, wherein the gas cylinder is connected with the flexible cryoprobe directly or connected with the flexible cryoprobe through the frozen host, making gas of the gas cylinder enter into the frozen host and passing different precooling controls and entering into the flexible cryoprobe lastly. The gas conducts throttling and refrigerating on the internal cutting head of the fore-end of the flexible cryoprobe, thereby getting into the pathological tissue of external cutting head conducting decalescence and freezing the pathological tissue. The cryotherapy system through natural orifice of human body adopts carbon dioxide, nitrous oxide, alkaline air and nitrogen as coolants, wherein alkaline air or nitrogenprecools in the frozen host and then conducts throttling and refrigerating while outputted into the cutting head and gains the temperature below 120o Celsius, which has larger refrigerating range easily, killing the pathological tissue thoroughly. The cryotherapy system through natural orifice of human body provides a new therapeutic scheme for problems of unreachable hard needle puncture and high risk on tumors of cavity.

Cold therapy is an established practice used in the medical profession to treat certain limb injuries, such as sprained or strained arm or leg muscles or injuries to joints. Generally, these types of injuries should be chilled to slow blood flow, which reduces swelling, pain, and further damage. Cold therapy is also an established practice used to treat migraine and other types of headaches. A typical course of cold therapy treatment is to apply ice for a specified period to the injured region of a limb, the neck, face, or head. Alternatively, a pack or bag containing a chemical agent that reacts (endothermically) to produce cold may be applied to the injured region, the neck, face, or head.

A cryotherapy system includes a cryotherapy catheter having an inflatable balloon portion and a pressure regulator. The inflatable balloon portion includes an outer balloon and an inner balloon within the outer balloon. The inner balloon is configured to receive during a cryotherapy procedure a cryogenic agent for extracting heat from body tissue at a desired location. The inflatable balloon portion is at a distal end of the cryotherapy catheter. The pressure regulator is adapted to maintain a positive pressure between the inner balloon and the outer balloon during a cryotherapy procedure.
