An arthroplasty device is provided having an interpenetrating polymer network (IPN) hydrogel that is strain-hardened by swelling and adapted to be held in place in a joint by conforming to a bone geometry. The strain-hardened IPN hydrogel is based on two different networks: (1) a non-silicone network of preformed hydrophilic non-ionic telechelic macromonomers chemically cross-linked by polymerization of its end-groups, and (2) a non-silicone network of ionizable monomers. The second network was polymerized and chemically cross-linked in the presence of the first network and has formed physical cross-links with the first network. Within the IPN, the degree of chemical cross-linking in the second network is less than in the first network. An aqueous salt solution (neutral pH) is used to ionize and swell the second network. The swelling of the second network is constrained by the first network resulting in an increase in effective physical cross-links within the IPN.

Processes for removing cells and cell debris from tissue and tissue constructs used in transplantation and tissue reconstruction
InactiveUS20070123700A1Improve inflammatory responseImprove responseHeart valvesDead animal preservationPresent methodFresh Tissue
Methods for decellularizing mammalian tissue for use in transplantation and tissue engineering. The invention includes methods for simultaneous application of an ionic detergent and a nonionic detergent for a long time period, which may exceed five days. One method utilizes SDS as the ionic detergent and Triton-X 100 as the nonionic detergent. A long rinse step follows, which may also exceed five days in length. This long duration, simultaneous extraction with two detergents produced tissue showing stress-strain curves and DSC data similar to that of fresh, unprocessed tissue. The processed tissue is largely devoid of cells, has the underlying structure essentially intact, and also shows a significantly improved inflammatory response relative to fresh tissue, even without glutaraldehyde fixation. Significantly reduced in situ calcification has also been demonstrated relative to glutaraldehyde fixed tissue. Applicants believe the ionic and non-ionic detergents may act synergistically to bind protein to the ionic detergent and may remove an ionic detergent-protein complex from the tissue using the non-ionic detergent. The present methods find one exemplary use in decellularizing porcine heart valve leaflet and wall tissue for use in transplantation.

Non-ionic non-aqueous vehicles for topical and oral administration of carrier-complexed active agents
InactiveUS20070036843A1Control releaseLow costOrganic active ingredientsPharmaceutical non-active ingredientsActive agentNon ionic
An improved controlled release composition for non-parenteral administration of active agents and other therapeutics, particularly for oral or topical administration, has been developed. The composition is made by dispersing a complex formed of an active agent bound to an ion-exchange resin or to another form of resin or carrier, in a non-ionic non-aqueous (“NINA”) vehicle. The complexes are optionally coated with one or more layers of coating material to provide a controlled pattern of release of active agent from the carrier. Replacing the usual aqueous vehicle with a NINA vehicle, such as an oil or an ointment, allows the active agent-carrier complexes, with or without coatings, to be both orally and topically administered. The compositions can be formulated as powders, liquids, liquid suspensions, gels, capsules, soft gelatin capsules, tablets, chewable tablets, topical ointments, lotions, pourable or pumpable fluids, semisolid, crushable tablets, and unit-of-use sachets or capsules for reconstitution or direct application. The combination of multiple active agents is possible with this system, in which one or more active agents are bound to particles and one or more active agents are dissolved or dispersed in the NINA vehicle. This allows the combination of two or more active agents, which are otherwise incompatible, into a single dosage form.
