A method for processing biological tissue used in biological prostheses includes providing a tissue procurement solution formed from a phosphate buffered saline (PBS) solution and a chelating agent. The tissue is transferred from the tissue procurement solution and undergoes chemical fixation. The fixed tissue is then immersed in a series of fresh bioburden reduction process (BRP) solutions to extract phospholipids. The tissue procurement solution reduces the bioburden on the stored tissue and preserves tissue architecture by minimizing tissue swelling. The tissue procurement solution further reduces calcium from the incoming water and / or tissue, and inhibits enzymes that digest the collagen matrix. The serial immersion of the tissue in the fresh bioburden solutions ensures optimal extraction of phospholipids thereby mitigating subsequent calcification of the tissue.

Devices with internal flexibility sipes, such as slits, provide improved flexibility, improved cushioning to absorb shock and / or shear forces, and improved stability of support. Siped devices can be used in any existing product that provides or utilizes cushioning and stability.

The present invention relates to cushioning apparatus having a plurality of intersecting columns, the columns being formed from a thermoplastic, silicone, two-part, or other gel material. The cushioning apparatus are extremely strong and durable yet provide an improved cushioning apparatus. The intersecting columnar configuration of the cushioning apparatus allow for weight to be shared with neighboring column walls. When force is exerted on the columns, the column walls are designed to buckle in the areas of greatest pressure. The column buckling diffuses energy from the areas of highest pressure effectively eliminating pressure points. As the polymer gel collapses within the column walls, the column walls essentially collapse at least partially in a lateral direction allowing pressure to flow away from the areas of greatest pressure to areas of lesser pressure. This provides an improved cushioning surface on which a user can sit, sleep, or other types of cushioning can be provided.

Opposable surgical clamp members having opposable resilient pads with wedge-shaped and cylindrical protrusions extending from the surfaces of the pads and the use of such members for occluding vessels and other tubular body structures are described. The protrusions are arranged such that when the members are moved toward one another, the protrusions of one pad interdigitate with the protrusions of the other pad. Upon engagement with a vessel, portions of the vessel are forced into the interdigital spaces providing for improved gripping of the vessel. The protrusions also resist lateral or transverse movement of a clamped vessel relative to the pads. The existence of through holes under the pad surface alters the relative resiliency of the pad, allowing for an overall pad resiliency that minimizes trauma to a clamped vessel while allowing the local resiliency of the protrusions themselves to be of a hardness to avoid excessive deflection and retain the desired shape and gripping ability.

Techniques whereby a transmitter / receiver pair are cooperatively arranged to buffer incoming data to both the transmitter and the receiver. The transmitter and receiver of the pair are coupled, generically, by pre-existing channel which has a known, fixed capacity. The transmitter / receiver pair exploits whatever delay is permissible, as determined by end-users of the data, for the data stream or streams that are using the channel for the purpose of accommodating periods of excessive instantaneous aggregate data transfer demands. The matched transmitter / receiver pair thereby permits (i) the transmission of a variable rate stream over a channel with capacity less than the peak rate of the stream, or (ii) the multiplexing of variable and / or fixed rate data streams.

A self inflating pneumatic seat cushion, especially for automobile seats, has foam filled bladders and bolsters. A pneumatic pumping chamber intakes air through an inlet and distributes air to the cushion bladders and bolsters through outlet tubes. The motion of a seat occupant against the pneumatic pumping chamber bladder operates to let air in through the inlet and distribute it through the outlet tubes. A collapsible seat has an exhaust valve for compressing the bladders in a stowed position. The exhaust valve may have an adjustable pressure release.

A trim component includes a foam backing layer and a foam pad insert laminated between a cover material and a substrate. The foam pad insert provides an area of enhanced cushioning, and has smoothly tapered edges to ensure a smooth surface contour without a visible edge transition on the cover material. The foam pad insert has a lower melting temperature than the foam backing layer, both of which are thermoplastics. A foam pad insert is positioned and fixed on the back surface of the foam backing layer. A substrate material is heated and then laminated and molded with the foam and the cover material. The heat from the substrate partially softens and melts the foam backing layer and the foam pad insert. The partially melted foam pad insert is viscously deformed to form the tapered edges, as dictated by the smoothly varying mold gap spacing of the forming tools.
