Title: Computer based medical procedure simulation system
Inventor: MERRIL JONATHAN R
IPC: G09B23/28
Filed: 1995-03-13
Abstract: A virtual reality medical simulation system provides a highly realistic simulation of a variety medical procedures, particularly catheter based procedures such as balloon angioplasty. A catheter interface device tracks a catheter wire in translation and rotation and output a signal to a computer program that displaysmovement of a virtual catheter within a virtual arterial tree including an occluded region. The catheter tip is navigated through the arterial tree and into the occluded region, whereupon the computer program generates a tactile feedback force that is output to the catheter interface device to simulate increased resistance. Once the catheter is properly positioned within the occlusion, a virtual balloon catheter can be inflated to remove the occlusion. A variety of special effect enhancements are included in the simulation, including 3-D imaging, simulated radio-opaque dye infusion, bleeding and atrial pulsation in synchronism with an on-screen EKG display. The simulation also includes case specific or randomly generated patient conditions and complications, as well as various user dependent error conditionssuch as puncture of the arterial wall and balloon rupture.

Patent CA-2178372-A1 (CA)
Inventor: SCHNEIDER CHARLES R
IPC: H01F41/12
Filed: 1996-06-06
Abstract: An ignition coil for an internal combustion engine and a method of making the same in which layers of the secondary winding are separated by a non-filtering/non-segregating material embedded in an electrically insulated ignition coil housing. The preferred non-filtering secondary winding separator is a solid filament, non-absorbing/non-adsorbing mesh, such as a nylon mesh. Using the non-filtering/non-segregating secondary winding separator prevents filler damming when an ignition coil housing is manufactured using a vacuum encapsulation and curing process in which an encapsulation compound (e.g. a thermal setting epoxy) has solid additives (e.g. sand fillers). Non-absorbing/non-adsorbing separators are also advantageous because the separators do not alter the chemistry of the encapsulation compound.
