Latest Patents

One of Kaar's latest patents involves microminiature patterned metal on medical grade balloons. This innovation features a thin-walled balloon formed from polymer tubing, which has a patterned metal layer on its outer surface. The metal layer is created through a process known as physical vapor deposition (PVD). The pattern is defined by a stencil mask that is assembled around the balloon while it is inflated. This PVD process is designed to occur without deforming or degrading the polymer material of the balloon. Kaar's method actively pulls heat away from the balloon by utilizing a metal stencil mask, providing a metal heat conduction path to a heat sink, and/or flowing a cooling fluid within the balloon during the PVD process. The parameters for the PVD process are carefully selected to minimize heat generation, ensuring optimal performance.
