| 20080208181 | Thermally Insulated Needles For Dermatological Applications - For active thermal insulation of a cryoneedle or hyperthermia needle, preferably, the device comprises a needle for transmitting heat or cold, surrounded by a sheath for providing an opposing temperature to protect surrounding skin. | 08-28-2008 |
| 20080307800 | Siphon for Delivery of Liquid Cryogen from Dewar Flask - The invention involves a siphon for delivery of a liquid cryogen from a container such as a Dewar flask. The siphon ensures delivery of a liquid cryogen with a lower proportion of the gaseous fraction. The siphon comprises a central feeding conduit, which is largely contained within the Dewar flask. There is an auxiliary conduit surrounding the central feeding conduit; the outer upper section of this auxiliary conduit is provided with an adjustable valve intended to release a gaseous fraction of the cryogen contained in the annular gap between the auxiliary and central feeding conduits. The upper section of the central feeding conduit is provided with an external layer of a porous capillary coating or with a wick; this ensures that the upper section of the central feeding conduit is continuously wetted with the liquid cryogen. This porous capillary coating prevents gasification of the liquid cryogen in the central feeding conduit. Alternatively, the problem of liquid cryogen gasification may be solved through thermal insulation of the central feeding conduit. | 12-18-2008 |
| 20090082761 | CRYOSURGICAL INSTRUMENT WITH EMBEDDED SEPARATING UNIT - A cryosurgical instrument, in which a separator is installed in a central feeding lumen and/or in a cryotip to separate gaseous and liquid components of a cryogen. | 03-26-2009 |
| 20090129946 | Pumping unit for delivery of liquid medium from a vessel - A pumping unit for delivering a liquid medium from a low pressure vessel such that the delivered medium has sufficiently high pressure, by providing the liquid medium in the form of separated pulses. | 05-21-2009 |

| 20100324546 | CRYOSHEATH - A device, system and method for a cryoprobe which features a heating component for heating at least a proximal portion of the tip of the cryoprobe, thereby preventing damage to an adjacent portion of tissue. | 12-23-2010 |
| 20110015624 | CRYOSURGICAL INSTRUMENT INSULATING SYSTEM - A device, system and method for controlling the temperature differential between the medium within the cryosurgical instrument and the external temperature of the shaft, apart from at the cryotip itself, uses a fluid medium supplied within an internal space between the shaft and an intermediate lumen positioned between the shaft and a central feeding lumen of the cryosurgical instrument. The temperature of the fluid medium is controlled to provide control of the temperature differential. | 01-20-2011 |
| 20110178514 | Cryosurgical Instrument Insulating System - A device, system and method for controlling the temperature differential between the material within the cryosurgical instrument and the external temperature of the shaft, apart from at the cryotip itself. | 07-21-2011 |
| 20110178523 | TOOL AND CORRESPONDING METHOD FOR REMOVAL OF MATERIAL FROM WITHIN A BODY - A device for removing material from within the body, includes an elongated element formed from hollow segments sequentially interconnected at effective hinges. The device assumes an insertion configuration for insertion of the segments sequentially through an opening of a first dimension into the body. A portion of the elongated element inserted into the body progressively assumes a material removing configuration in which a relative position of each segment relative to an adjacent segment is delineated by the effective hinge together with additional abutment surfaces defining a fully deflected state of the effective hinge. The material removing configuration has at least two dimensions exceeding the first dimension. At least two of the segments are formed with at least one opening, typically provided with a cutting configuration, deployed so as to receive material into a hollow volume of the segment during progressive formation of the material removing configuration as the elongated element is advanced. | 07-21-2011 |
