Abstract:
This invention relates to stents, a type of implantable medical device, with an antiproliferative coating and a prohealing luminal coating and methods of fabricating stents with an antiproliferative coating and a prohealing luminal coating.
Abstract:
Described here are devices and methods for treating one or more conditions or symptoms associated with a tonsil procedure. In some variations, a drug-releasing device may be at least partially delivered to one or more tonsillar tissues before, during, or after a tonsil procedure. In some variations, the drug-releasing device may be configured to be biodegradable. In other variations, the drug-releasing device may comprise one or more hemostatic materials or one or more adhesives. The drug-releasing device may be configured to release one or more drugs or agents, such as, for example, one or more analgesics, local anesthetics, vasoconstrictors, antibiotics, combinations thereof and the like.
Abstract:
Techniques for implementing vocoders in parallel digital signal processors are described. A preferred approach is implemented in conjunction with the BOPS® Manifold Array (ManArray™) processing architecture so that in an array of N parallel processing elements, N channels of voice communication are processed in parallel. Techniques for forcing vocoder processing of one data-frame to take the same number of cycles are described. Improved throughput and lower clock rates can be achieved.

Abstract:
Methods to expand polymer tubing with desirable or optimum morphology and mechanical properties for stent manufacture and fabrication of a stent therefrom are disclosed.
Abstract:
A machining simulation apparatus is arranged in a machine tool having a tool holding mechanism, a workpiece holding mechanism, a drive mechanism and a numerical controller, and provided with: an actual CCD camera for imaging a tool held by the tool holding mechanism and the workpiece holding mechanism not holding a workpiece to generate actual image data; a model data update processing section for generating model data relating to when moving the holding mechanisms based on the operation command received from the numerical controller and the model data of the holding mechanisms, tool and workpiece; a virtual image generation processing section for generating virtual image data of the tool and workpiece based on the generated model data; and a rendering processing section for generating composite image data by superimposing the virtual image on the actual image, and displaying the composite image data on a screen display device.
Abstract:
Methods for improved stent retention on an expandable member during delivery are disclosed. Methods include fabricating delivery systems including a degradable or water soluble sheath over the stent, the expandable member, or both for improving retention of the stent on the expandable member during delivery.
Abstract:
A device and a method of manufacturing an implantable medical device, such as a stent, are described herein. The device includes a metallic region composed of a bioerodable metal and a polymer region composed of a biodegradable polymer contacting the metallic region. The metallic region may erode at a different rate when exposed to bodily fluids than the polymer region when exposed to bodily fluids. In certain embodiments, the polymer region is an outer layer and the metallic region is an inner layer of the device.
