  • Publication number: 20190046689
    Abstract: A cell growth matrix is provided that comprises a biodegradable elastomeric polymer electrodeposited concurrently with a sprayed or electrosprayed liquid that is a physiological solution or which comprises a mammalian blood product such as serum, plasma or platelet rich plasma. The matrix is useful as a cell-growth matrix and for repair of a tissue in a mammal, for instance by implantation in a mammal at a site in need of repair, such as in an abdominal wall.
    Type: Application

  • Patent number: 9968714
    Abstract: Provided herein is a biodegradable elastomeric patch that can be implanted on a heart or other portions of the cardiovascular system to repair tissue deficiencies or tissue damage. The biodegradable elastomeric patch may be engineered to have mechanical properties similar to that of soft tissue and to provide mechanical support to the damaged tissue. The biodegradable elastomeric patch also may comprise therapeutic agents to aid in the healing process. Methods also are provided for using a biodegradable elastomeric patch for treating patients suffering from tissue damage or tissue deficiencies in the cardiac or cardiovascular system.

  • Patent number: 9408855
    Abstract: Provided are novel biocompatible copolymers and compositions comprising the copolymers. The copolymers are non-toxic and typically have an LCST below 37° C. Compositions comprising the copolymers can be used for wound treatment, as a cellular growth matrix or niche and for injection into cardiac tissue to repair and mechanically support damaged tissue. The copolymers comprise numerous ester linkages so that the copolymers are erodeable in situ. Degradation products of the copolymers are soluble and non-toxic. The copolymers can be amine-reactive so that they can conjugate with proteins, such as collagen. Active ingredients, such as drugs, can be incorporated into compositions comprising the copolymers.

  • Patent number: 8889791
    Abstract: Provided are novel biocompatible copolymers and compositions comprising the copolymers. The copolymers and degradation products thereof are non-toxic and typically have an LCST between room temperature and 37° C. so that they are liquid at room temperature and gelled at 37° C. which facilitates their use in humans, for example for wound treatment and as a cellular growth matrix or niche. The copolymer comprises numerous ester linkages in its backbone so that the copolymers are erodeable in situ. Degradation products of the polymer are soluble and non-toxic. The copolymer is amine-reactive so that it can conjugate with proteins, such as collagen. Active ingredients, such as drugs, can be incorporated into compositions comprising the copolymer.
