摘要： 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.

摘要： Described are embodiments of a multilaminate or multiple layer implantable surgical graft with an illustrative graft comprising a remodelable collagenous sheet material, the graft including one or more interweaving members to stitch together the graft to help prevent the layers from delaminating or separating during handling and the initial stages of remodeling. The interweaving members may comprise lines of suture, thread, individual stitches, strips of material, etc. that are woven through the layers of biomaterial in a desired pattern. In one embodiment, the interweaving members comprise a pharmacologically active substance, such as a drug, growth factors, etc. to elicit a desired biological response in the host tissue. In another embodiment, the graft further comprises a reinforcing material, such as a synthetic mesh, within the layers of remodelable biomaterial and stitched together by one or more interweaving members.

摘要： Various compositions of matter, methods of making compositions of matter, and methods of using compositions of matter, e.g. for inducing hemostasis, are disclosed. In some embodiments, a starting fibrin material is subjected to controlled hydrolysis, desirably base-catalyzed, to prepare a fibrin hydrolysate material with increased water sorption capacity. Such fibrin hydrolysate materials, alone or combined with one or more additional substances, can be used in the preparation of hemostasis promoting foams, powders or gels. In some embodiments, a starting dialdehyde starch material is subjected to controlled hydrolysis to prepare a dialdehyde starch hydrolysate material. Such dialdehyde starch hydrolysate materials, alone or combined with one or more additional substances, in some cases combined with a fibrin hydrolysate material, can be used in the preparation of hemostasis promoting foams, powders or gels.

摘要： A filamentous graft has an elongate filament body including one or more intact segments of a decellularized collagenous tissue membrane. The graft can have a length of at least about 20 cm. The graft can be cut from a laminate of two or more decellularized collagenous tissue membranes. The graft can have a generally rectangular cross-section and can have substantially uniform dimensions and tensile strength along at least a substantial portion of its length. Methods for preparing and using filamentous grafts are also described.

摘要： Medical devices are described herein. More particularly, the disclosure relates to medical devices, systems, and methods for the visualization and treatment of bodily passages, such as an airway, sinus cavity, or sinus passages. An exemplary medical device comprises an elongate member, an actuator moveable between an actuator first position and an actuator second position, and a wire member. The elongate member has a first straight, or substantially straight configuration, when the actuator is in the actuator first position and a second curved configuration when the actuator is in the actuator second position.

摘要： Described are medical graft materials and devices which can be usefully modified with liquid additives such as cell suspensions, bioactive agents, or combinations of these. The medical graft materials and devices can have a first outer surface and a second outer surface and can define an internal chamber between the first outer surface and the second outer surface. The medical graft materials and devices can also have at least one region of the graft material interrupting the chamber and surrounded by the chamber. Also described are methods for making and using these medical graft materials and devices.

摘要： Among other things, there are disclosed apparatuses and methods for medically sealing an opening in a vessel or wall. For example, in medical applications, a delivery tube is provided for insertion through a sheath into a vessel (e.g. a blood vessel). A dome-shaped seal fixed to a filament, an absorbent and/or compressible buffer, and a locking member are provided in the delivery tube. The delivery tube is configured so that it can be inserted into the vessel through a sheath. Tension is maintained on the filament to hold the seal against the tube or sheath. The sheath is pulled out, which pulls out the tube at the same time, leaving the seal over the opening in the vessel wall. The locking member compresses the buffer against the outside of the vessel and with the filament holds the seal in place against the inside of a vessel.
