The fastener includes a head portion, a body portion, and an anchoring element. The anchoring element is on the distal end of the fastener, and has one or more barbs or similar anchoring devices that are configured to prevent removal of the fastener once it is attached to the body tissue. The head is located on the proximal end of the fastener, and anchors the body tissue or other material when the fastener is attached to the body tissue. The disclosure also provides a driver apparatus for inserting the fasteners. The applicator device includes an indexer for sequentially indexing one or more fasteners, and a driver for applying an insertion force to a fastener that is sufficient to insert the fastener and attach it to body tissue. The disclosure also provides a method of using the fastener and applicator device.02-02-2012
20120029537PROSTHETIC DEVICE AND METHOD OF MANUFACTURING THE SAME - A biocompatible surgical silk mesh prosthetic device employs a knit pattern that substantially prevents unraveling and preserves the stability of the mesh device, especially when the mesh device is cut. An example prosthetic device employs a knitted mesh including at least two yarns laid in a knit direction and engaging each other to define a plurality of nodes. The at least two yarns include a first yarn and a second yarn extending between and forming loops about two nodes. The second yarn has a higher tension at the two nodes than the first yarn. the second yarn substantially prevents the first yarn from moving at the two nodes and substantially prevents the knitted mesh from unraveling at the nodes.02-02-2012
20100069927Polymeric Masking Materials for Spanning Wound Sites, and Methods of Use Thereof - One aspect of the present invention generally relates to methods of sealing a defect, wound or void using a two component system composed of masking material, which creates an anti-adhesion barrier, and a covering material. In certain embodiment, the covering material comprises an in situ polymerizing sealant. In certain embodiments, the in situ polymerizing sealant is a hydrogel which binds to the healthy tissue but remain unadhered to the area under the masking material. In certain embodiments, the masking material is also a hydrogel. In certain embodiments, normal biological processes may dissolve away the masking material leaving a protective cover of polymerized sealant over the wound site.03-18-2010
