20110208129 | PRESSURE ACTUATED CATHETER SEAL AND METHOD FOR THE SAME - A catheter includes a pressure actuated seal within a manifold. A catheter body is coupled with the manifold, and a manifold lumen and catheter lumen are configured to receive pressurized fluids. The pressure actuated seal includes a pressure actuated seal element having a seal element lumen. The seal element lumen is in communication with the manifold and catheter lumens. The pressure actuated seal element is deformable between an open configuration and a sealed configuration. In the sealed configuration, the pressurized fluid in the manifold presses on the pressure actuated seal element along a first seal face. The pressure actuated seal element compresses inwardly around the seal element lumen according to the pressure of the pressurized fluid. In the open configuration, the pressure actuated seal element relaxes in the absence of the pressurized fluid, and the seal element lumen is open and configured to allow passage of an instrument. | 08-25-2011 |
20140276602 | CATHETER SYSTEM - A multi-station hydrodynamic catheter includes an outer catheter having a first lumen, the outer catheter having a plurality of orifice stations positioned along a portion of the outer catheter, where each orifice station includes one or more orifices extending from an outer catheter external surface to the first lumen. The multi-station hydrodynamic catheter includes an inner catheter having a second lumen, the inner catheter movable within the first lumen and includes at least one emanator, where the at least one emanator includes one or more fluid delivery ports extending from an inner catheter external surface to the second lumen. | 09-18-2014 |
20140277006 | THROMBECTOMY CATHETERS, SYSTEMS AND METHODS - Thrombectomy catheters having at least one outflow orifice and one or more inflow orifices, systems including the thrombectomy catheters, and methods of using the thrombectomy catheters are described herein. The thrombectomy catheters described herein may include one or more of the protective features that may limit potential hazards to vessel walls in which the thrombectomy catheters are used. | 09-18-2014 |

20130087180 | WEARABLE THERMOELECTRIC GENERATOR SYSTEM - A wearable thermoelectric generator system thermoelectric generator may include a thermoelectric generator, a heat collector, and a heat exchanger. The heat collector may be configured to be placed in contact with a skin surface of a wearer. The heat exchanger may be configured to be exposed to ambient air. The thermoelectric generator may be mounted between the heat collector and the heat exchanger. The thermoelectric generator may be electrically connected to a load. The load may be packaged separately from the thermoelectric generator. | 04-11-2013 |
20140299169 | ELECTRONIC POWER MANAGEMENT SYSTEM FOR A WEARABLE THERMOELECTRIC GENERATOR - A power management system for an energy harvesting device configured to provide a source voltage. The power management system may include a conditioning and control circuit configured to perform an initialization process by accumulating energy from the source voltage until an output voltage becomes regulated for a load. The power management system may include a priming circuit configured to supplement the source voltage during a load period upon actuation of a power management switch which may cause the transferring of a priming charge from a low-leakage energy storage element to the conditioning and control circuit. The conditioning and control circuit may combine the priming charge with the energy accumulating from the source voltage. The initialization process may cause the output voltage for the load to become regulated during the load period following actuation of the power management switch. | 10-09-2014 |
