Abstract: The multiple optical fiber event sensor apparatus includes a semipermeable generally cylindrical shaft, one or more optical fiber gas sensor modules within the shaft, and an optical fiber pH sensor module extending beyond the distal end of the shaft, with the sensor modules arranged in an axially staggered relationship. The shaft contains a potting matrix for axially fixing the position of the optical fibers, and includes a gas permeable portion surrounding the one or more gas sensor modules, and a hydrophilic portion covering at least part of the pH sensor module. A hemodynamically shaped, rounded distal end is also provided on the distal end of the shaft. The device provides for a multiplicity of individual sensors incorporated in a single shaft which minimizes cross-interference and thrombus formation when used as an intravascular multi-sensor.

Abstract: An intraocular lens of the type having a plurality of legs which enter the lens in the anterior or posterior chamber by tangential contact between eye tissue and a region on each leg, wherein the region is composed of a compressible material. Also disclosed are homogeneous lenses in which the legs are colored.
