20090248048 | PROSTHETIC FOR TISSUE REINFORCEMENT - A process for the manufacture of a prosthetic sheet with improved tissue healing characteristics useful in reinforcing tissue defects is disclosed. Generally the prosthetic may be comprised of any material that does not promote fibrosis and inflammation. In particular, the prosthetic may be comprised of non-absorbable hydrogel reinforced with fiber, so that the fiber reinforcement is encapsulated and shielded from interaction with tissue. The prosthetic may contain pores that pass through it to encourage tissue through-growth. These pores may be made by removing material from a sheet of reinforced hydrogel or the reinforcement means may contain a porosity around which the hydrogel is formed and the porosity is maintained. | 10-01-2009 |
20110196189 | EXTRA-CARDIAC DIFFERENTIAL VENTRICULAR ACTUATION BY INERTIAL AND BARIC PARTITIONING - A device for extra-cardiac actuation for the support of a failing heart is provided that utilizes the inertial component of a driving fluid to provide separately adjustable quantities of supportive energy to the left and right ventricles. By partitioning the inertial and baric forms of energy delivered to a single chamber, heart encircling assist device, and by localizing the heart to minimize lateral and axial displacement a device and method for achieving balanced left-right flow is disclosed that restores the Frank-Starling mechanism to a failing heart and assists recovery by enabling the heart to achieve physiologic cardiovascular equilibrium. | 08-11-2011 |

The disclosure also relates to a medical assembly comprising a surgical barrier aspect, a short term mucoadhesive aspect, an intermediate term protein polymerization adhesive aspect, and a long term tissue ingrowth implant localization aspect. The aforementioned medical assemblies may be provided as layered sheet structures. Also provided are methods for preparing a medical assembly. | 02-28-2013 |
20130095161 | COPOLYMERS OF HYDROPHOBIC AND HYDROPHILIC SEGMENTS THAT REDUCE PROTEIN ADSORPTION - The present disclosure relates to compositions A composition comprising a polymerization product of an anionic polysaccharide, a diisocyanate, and a linker, wherein the linker comprises i) an ether group, an ester group, or a combination thereof and, ii) a chain extender comprising a hydroxyl group, a thiol group, an amine group, or a combination thereof. The disclosure further relates to medical devices comprising the aforementioned compositions, and to methods of using the compositions and devices. More particularly, the compositions, devices and methods described herein are useful for preventing protein adhesions in vivo, particularly the Vroman effect. | 04-18-2013 |

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 |
20130317286 | ANTI-EROSION SORFT TISSUE REPAIR DEVICE - The present disclosure relates to surgical implants comprising a bioabsorbable incision reinforcement element, a long-term mesh, and a bioabsorbable coating disposed on the mesh. The surgical implants disclosed herein are useful in a variety of surgical procedures, particularly surgeries involving the pelvic floor. More particularly, the present disclosure relates to surgical implants, wherein an incision reinforcement element comprises a bioabsorbable material that degrades during a first time period, and the coating comprises a bioabsorbable material that degrades in a second time period, and the first time period is shorter than the second time period. | 11-28-2013 |
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 |
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 |
20140271503 | Topical With Static Photobiological Functionality - Compositions and methods thereof, for preventing or minimizing skin penetration and that promote surface-layer fixation of dermatological molecules in a human body are disclosed. The molecules of the present invention and compositions containing said molecules comprise a tissue-reactive part, an amphiphilic part, a light-functional part and optionally a detachment mechanism for releasing said tissue-reactive part from said light-functional part. The methods include ways of combining the tissue-reactive part, amphiphilic part, light-functional part and optionally synthesizing a detachment mechanism therein. The parts when combined form molecular structures possessing novel photobiological persistence and efficacy. | 09-18-2014 |
20140271523 | Nitric Oxide Releasing Multifunctional Polymers - A molecule for stabilizing a bioactive chemical group capable of releasing nitric oxide in vivo is described. The molecule possesses multi-functionality, enabling the delivery of multiple nitric oxide precursors on a single molecule. In some embodiments, a tissue or prosthetic bonding group is attached to one of the functional arms of the molecule making the molecule of the present invention localizing to tissue or an implant. | 09-18-2014 |
