摘要:
The present disclosure relates to compositions suitable for use as medical devices and/or coatings thereon. In embodiments, the compositions may be used to adhere and/or seal tissue. In other embodiments, coatings may be used to at least temporarily affix a medical device to tissue. The coatings may affix a medical device to tissue without the need for additional fixation devices or, in embodiments, may be used with other fixation devices to affix a medical device to tissue.
摘要:
A hydrogel composition comprising: a first hydrogel comprising a first reactive precursor comprising a multi-arm polyether possessing electrophilic groups, a second reactive precursor comprising nucleophilic groups, and at least one bioactive agent; and
a barrier layer on an external surface of the first hydrogel, the barrier layer comprising at least one initiated precursor selected from the group consisting of phosphorylcho line containing monomers, furanone functional vinyl monomers, N-vinyl pyrrolidone, siloxane functional vinyl compounds, polyethylene glycol-silicone co-monomers having vinyl groups, pyrrole, liquid crystalline vinyl monomers, liquid crystalline vinyl polymers, and combinations thereof, wherein the barrier layer directs delivery of the bioactive agent from the first hydrogel in a direction opposite the barrier layer.
摘要:
A biodegradable triblock copolymer comprising: an A-B-A' structure wherein the A and A' blocks each include polylactide, the B block includes from about 55 to about 100 mole percent of polytrimethylene carbonate and 0 to about 45 mole percent polylactide, and the biodegradable triblock copolymer overall includes from about 15 to about 25 mole percent of the polytrimethylene carbonate and from about 75 to about 85 mole percent of the polylactide. Also provided are compositions and implantable medical devices made therefrom.
摘要:
The present disclosure relates to a medical device and methods of using the same. In embodiments, the medical device may be a buttress formed of nucleophilic buttress components and electrophilic buttress components which react to both form the buttress and provide the buttress with self-sealing capabilities after a staple or some other fixation device is placed therethrough, thereby enhancing its hemostatic properties. In other embodiments, the medical device is a hernia patch formed of a fibrous substrate, nucleophilic precursor components and electrophilic precursor components.
