  • Patent number: 7850985
    Abstract: Tissue augmentation devices, as well as methods of manufacturing and using the same, are disclosed. In certain embodiments, a tissue augmentation device comprises an elongate tissue penetrating member and an amount of remodelable material, wherein at least a portion of the elongate member is cannulated, and at least a portion of the amount of material is received within at least a portion of the cannulated portion of the elongate member. The elongate tissue penetrating member may provide at least one deformation that is configured to constrict portions of the amount of remodelable material received within the elongate member. In alternate embodiments, a flexible covering over an implantable biomaterial provides protection and allows an easier delivery of the biomaterial to a tissue tract.

  • Patent number: 7766926
    Abstract: A sling for supporting a urethra in a patient has characteristics for resisting pull-out, roll-over and a combination of both pull-out and roll-over. To facilitate resistance to pull-out, sling material has protuberances or serrations to resist movement once placed in the patient by the surgeon. Improved resistance to roll-over or roll-up is achieved by providing relief on the sling in areas potentially subjected to roll-over forces by endopelvic fascia. The sling may be used on female or male patients, and may be used in conjunction with a wider support portion to support a bladder and a urethra, rather than a urethra alone. The sling may also be used to support other tissues within a patient.

  • Publication number: 20100114307
    Abstract: Prosthetic valve devices, as well as systems and methods for the delivery thereof, are disclosed. A device includes one or more leaflets disposed within a frameless conduit, wherein the conduit is adapted for attachment to walls of a vascular vessel, and the leaflets are adapted for attachment to walls of the conduit. The leaflets are configured to selectively restrict blood flow through the conduit, and the conduit can include wall-engaging adaptations, for example, barbs or an adhesive. The conduit and the leaflets are formed with a flexible material, which may comprise a remodelable material and/or a synthetic polymer.

  • Publication number: 20090306688
    Abstract: Described are embodiments of a multilaminate or multiple layer implantable surgical graft comprising 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.
