20080228249 | MEDICAL DEVICE WITH THERMAL MANAGEMENT OF THE DEVICE-TISSUE INTERFACE - A medical device includes a heat-generating region and a thermally conductive body thermally and mechanically coupled to the heat-generating region. The conductive body encloses a cavity that is filled with thermal ballast. The cavity ideally extends along at least 50% of the length of the conductive body. The thermal ballast may be a phase-change material. | 09-18-2008 |

20120004601 | Interventional procedure drive and control system - A pumping system for use in medical applications where liquids must be infused and aspirated from a mammalian patient, and whose economics are such that it is cost effective to simply dispose of it after a single use. The system features positive displacement pump(s) such as reciprocating pump(s) containing a damping mechanism to dampen out the peaks and valleys in the fluid pressure that is pumped, which is important for preventing cavitation. The system furthermore features a shut-off valve on the extraction side so that certain injected fluids such as contrast medium, are not immediately pumped out of the patient. In a preferred embodiment, the system also features means for independently controlling the fluid pressure/volume on the infusion and extraction sides, self-priming capability, a continuous fluid path, and visual air bubble detection, with viewports located at important points in the fluid path, such as at pumps and valves. | 01-05-2012 |
