20080312644 | CRYOGENIC BALLOON ABLATION INSTRUMENTS AND SYSTEMS - Cryogenic tissue ablation instruments for treating body tissue include an elongate flexible body with a proximal supply port for coupling with a pressurized coolant (e.g., liquid N | 12-18-2008 |
20120265278 | INTEGRATED CRYOSURGICAL SYSTEM WITH REFRIGERANT AND ELECTRICAL POWER SOURCE - A system for treating tissue in a patient includes a body having a cooling fluid supply path and a tissue piercing probe in fluid communication with the cooling fluid supply path. The probe extends distally from the body and is insertable into the tissue through the patient's skin. A cooling fluid source is fluidly coupled with the probe such that when cooling is initiated, cooling fluid flows in the probe thereby cooling the probe and any adjacent tissue. A heater element is in thermal engagement with the cooling fluid source and a power source provides power to the heater element thereby heating the cooling fluid. The power source has sufficient power to heat the cooling fluid to at least a desired temperature but has insufficient power to heat the cooling fluid above a critical temperature which results in rupture of the cooling fluid source. | 10-18-2012 |
20120310226 | CRYOGENIC BALLOON ABLATION INSTRUMENTS AND SYSTEMS - A cryogenic tissue ablation instrument includes an elongate flexible body with a proximal supply port for coupling with a pressurized coolant, a supply lumen in communication with the proximal supply port, and an expandable balloon carried on the elongate body. A dispersion member coupled to the elongate body has an interior lumen in communication with the supply lumen, the dispersion member having one or more coolant dispersion apertures sized and located such that a pressurized flowable coolant will enter the balloon interior in the form of a liquid spray that contacts and provides substantially uniform cooling of the balloon. | 12-06-2012 |
20130184694 | Cryogenic Probe Filtration System - A cryogenic device having a filter device fluidly connected between a valve and a cooling fluid cartridge. The filter device filters solid and fluid impurities received from the cartridge. The filter device also captures fluid impurities from the cryogenic device when not in use. | 07-18-2013 |
20130184695 | Skin Protection for Subdermal Cryogenic Remodeling for Cosmetic and Other Treatments - A cryogenic needle probe having a proximal and distal region. A cooling supply tube provides pressurized cooling fluid within the needle. The proximal region is more conductive that the distal region. The proximal region is conductively coupled to a heat source. | 07-18-2013 |
20130184696 | Cryogenic Needle with Freeze Zone Regulation - A cryogenic needle of a cryogenic system is coupled to a heater. While the needle is inserted into target tissue beneath skin, the heater provides heat to protect the skin. Power supplied to the heater is used to interpolate performance of the needle and/or operating parameters of the cryogenic system. | 07-18-2013 |
20130190745 | Cryogenic Probe System - A cryogenic system having a base unit tethered to a handpiece connectable to a needle probe. The handpiece holds a replaceable cryogen canister assembly. The base unit connects to mains to provide power to the handpiece. The base unit includes a back-up power source in the event of interruptions of power via mains. | 07-25-2013 |
20140207130 | CRYOGENIC BALLOON ABLATION INSTRUMENTS AND SYSTEMS - Cryogenic tissue ablation instruments for treating body tissue include an elongate flexible body with a proximal supply port for coupling with a pressurized coolant (e.g., liquid N | 07-24-2014 |
20150081007 | SYSTEMS AND METHODS FOR DEPLOYING A LUMINAL PROSTHESIS OVER A CARINA - A system for deploying a prosthesis over a Carina between an ipsilateral lumen and a contralateral lumen includes a guidewire, a guidewire capture catheter, a self-expanding tubular prosthesis, and a delivery catheter. The guidewire is first placed in the ipsilateral lumen. The guidewire capture catheter is then advanced from the contralateral lumen to a position at or above the ipsilateral lumen. The guidewire is typically advanced through an occlusion, which may be a total occlusion, and captured by a capture element on the guidewire capture catheter. The guidewire capture catheter pulls the guidewire out through the contralateral side, and the guidewire is used to advance a delivery catheter from the ipsilateral side. The delivery catheter delivers a first segment of the tubular prosthesis in the ipsilateral lumen and a second segment of the prosthesis in the contralateral lumen. | 03-19-2015 |
