  • Publication number: 20070027472
    Abstract: Described are medical devices useful for applying a bolster material to a surgical fastening device such as a stapler, and related methods of manufacture and use. The devices include an applicator element for receipt between arms of the stapler, and a bolster material, desirably a remodelable extracellular matrix material, coupled to the applicator element. In certain embodiments, the bolster material is held by the applicator element, for example having at least a portion looped around or received through or over a portion of the applicator element. Also described are unique implantable materials including coatings of dried, reversible adhesive.

  • Publication number: 20070004961
    Abstract: This invention relates in one aspect to the treatment of a vascular vessel with a biomaterial. The biomaterial can be a remodelable material that strengthens and/or supports the vessel walls. Additionally the biomaterial can include a variety of naturally occurring or added bioactive agents and/or viable cellular populations.

  • Publication number: 20060251702
    Abstract: Described are materials and methods for inhibiting the formation of tissue adhesions. In one aspect, a prosthetic tissue support mesh, and especially such a mesh comprised of a remodelable material that promotes tissue ingrowth, incorporates an effective amount of an anti-inflammatory compound such as a non-steroidal anti-inflammatory drug (NSAID) to inhibit the formation of tissue adhesions to the mesh and/or to surrounding tissues when implanted in a patient. Also described are materials and methods for increasing the length of persistence of implanted resorbable materials, and especially implanted bioremodelable materials, using an anti-inflammatory compound such as an NSAID.

  • Publication number: 20060210597
    Abstract: Described are preferred prosthetic valve devices including a first extracellular matrix material having a second extracellular matrix material deposited thereon. The preferred materials are made by culturing cells in contact with an extracellular matrix graft material in a fashion to cause the cells to biosynthesize and deposit extracellular matrix components on the material. The cells are then removed to provide the extracellular matrix composite material. In preferred embodiments, the prosthetic valve devices are configured for use in vascular applications.

  • Publication number: 20060136047
    Abstract: Described are preferred tissue graft materials that incorporate juvenile submucosa tissue from a warm-blooded vertebrate. Preferred materials incorporate juvenile small intestinal submucosa tissue from a mammal such as a porcine mammal, and the constructs are preferably in tubular form and utilized the isolated submucosa tissue in its native, intact tubular form. More preferred devices are multi-laminate and include the juvenile submucosa tissue in addition to at least one, and preferably several other layers providing increased strength or other advantageous properties to the construct.

  • Publication number: 20060116548
    Abstract: This invention relates in one aspect to the treatment of a valve-associated region of a vascular vessel with a biomaterial. The biomaterial can be a remodelable material that strengthens and/or supports the vessel walls. Additionally the biomaterial can include a variety of naturally occurring or added bioactive agents and/or viable cellular populations.

  • Publication number: 20050202058
    Abstract: Described are tissue graft constructs that include an extracellular matrix material in combination with added endothelial cells and at least one additional added exogenous cellular population. The additional exogenous cellular population desirably includes muscle cells, such as smooth muscle cells, fibroblasts, or a combination thereof. Tubular constructs seeded with such cell combinations can be beneficially used as vascular grafts. Also described are methods for preparing and using such grafts.

  • Publication number: 20050187604
    Abstract: A cast bioremodelable graft (22) comprising a cast tubular construct (33) of a bioremodelable substance (34). The bioremodelable substance is cast on or applied to a form and then vacuum pressed to dry or harden the substance. Expandable members (18) are disposed on, in, under or about the cast tubular construct to expand the graft when released from an endoluminal delivery system. A second layer (39) can be applied over the first layer (38) and the expandable stents to contain the stents there between without the need for any separate attachment. The graft is dehydrated and preferably vacuum pressed to harden the bioremodelable substance. The form is removed to form one or more lumens (23-25) in the graft, which is then loaded on an endoluminal delivery system.

  • Patent number: 5516533
    Abstract: A fluidized, injectable tissue graft composition is described. The composition comprises comminuted intestinal submucosa or protease-digested intestinal submucosa. Methods for the preparation and use of injectable tissue graft compositions are described. In preferred embodiments the tissue graft material is prepared from the intestinal submucosa comprising the tunica submucosa, the muscularis mucosa and the stratum compactum of a segment of intestinal tissue of a warm-blooded vertebrate. Effective amounts of the fluidized graft compositions can be injected to promote repair tissue defects by inducing formation of endogenous tissues.
