Inventor: BERMAN ANDREW B
IPC: A61F2/36
Filed: 1995-12-15
Abstract: The disclosure relates to a tissue and debris barrier for use in association with implanted joint replacement devices. The barrier comprises a biocompatible mem-brane that is impermeable to debris. The membrane de-fines an aperture which is positioned about a component of the joint replacement prosthesis. The periphery of the membrane may be mechanically attached by sutur-ing to adjacent tissue. The barrier permits full motion of the replacement joint while preventing or impeding tis-sue and debris from migrating to and from bone implant interfaces. The preferred barrier material is porous ex-panded PTFE with one side having a microstructure that promotes tissue attachment and the opposing side having a microstructure that allows highly efficient filtration of fine particulate debris. The barrier may be a single layer material or may be a composite construction in which two or more layers are bonded together.

Title: Corandomized fat compositions for infant formulas
Inventor: LIEN ERIC LOUIS
IPC: A23C11/10
Filed: 1995-05-11
Abstract: The invention disclosed herein comprises fat compositions primarily for use in nutritionaily complete infant formula in which the constituent palmitic acid oils and oleic acid oils are corandomized. The invention additionally includes such corandomized fat compositions with medium-chain triglycerides added, particularly for use in nutritional products for preterm or low birthweight infants. The corandomization of the palmitic acid oil and oleic acid oil yields a mixture of triglycerides having a substantially different chemical makeup than that of the native oils themselves, than the native oils when randomized individually, or than palmitic and lauric acids corandomized. The corandomization affords an economical means of providing a very highly absorbed fat composition and in particular results in a considerable reduction in the excretion, i.e, non-absorption, of palmitic acid.
