20140288582 | Implant Localization Device - An implantable medical device for providing structural support to tissue is described wherein the implant adheres to tissue without the benefit of suture, surgical adhesive and the like. The adherent or localization means is a hemostat or protein polymerizing materials such as oxidized cellulose, alpha cellulose, polyanhydroglucuronic acid and the like. The structure of the hemostat may be fibular (hallow and solid), woven, particulate, and the structure of hemostats in general. These protein polymerization compounds are beneficially attach to at least one side of a planar implant such as a surgical repair mesh, surgical barrier, and any implantable device intended to isolate or strength a layer of mammalian tissue. | 09-25-2014 |
20140207251 | BIO-SELECTIVE SURFACE TEXTURES - Bio-selective textured surfaces are described which mediate foreign body response, bacterial adhesion, and tissue adhesion on devices implanted in a mammalian body. Hierarchical levels of texture, some capable of establishing a Wenzel state others a Cassie state, are employed to interface with living structures, either to promote or discourage a particular biological response/interaction. Since a gaseous state is traditionally required to establish a Cassie or Wenzel state, and gases do not remain long in living tissue, described are tissue/device interactions analogous to the above states with the component normally represented by a gas replaced by a bodily constituent, wherein separation of tissue constituents develops and a desired interaction state evolves. | 07-24-2014 |
20140200679 | IMPLANTABLE SUPERHYDROPHOBIC SURFACES - Bio-adhesive textured surfaces are described which allow implants to be localized within a living body. Hierarchical levels of texture on an implantable medical device, some capable of establishing a Wenzel state and others a Cassie state, are employed to interface with living structures to provide resistance to device migration. Since a gaseous state is traditionally required to establish a Cassie or Wenzel state, and gases do not remain long in living tissue, described are tissue/device interactions analogous to the above states with the component normally represented by a gas replaced by a bodily constituent, wherein separation of tissue constituents develops and an analogous Cassie, Wenzel or Cassie-Wenzel state evolves. | 07-17-2014 |
20130196003 | CLASS OF ANTI-ADHESION HYDROGELS WITH HEALING ASPECTS - Disclosed are hydrogels polymerized with a biofunctional moiety, biodegradable and permanent, designed to be implantable in a mammalian body and intended to block or mitigate the formation of tissue adhesions. The hydrogels of the present invention are characterized by comprising four structural elements: a) a polymeric backbone which defines the overall polymeric morphology, b) linkage groups, c) side chains, and d) biofunctional end groups. The hydrophobicity of the various structural elements are chosen to reduce tissue adhesion and enhance the biofunctional aspect of the end groups. The morphology of these polymers are typically of high molecular weight and have shape to encourage entanglement. Useful structures include branching chains, comb or brush, and dendritic morphologies. | 08-01-2013 |
