207 results about "Tissue Graft" patented technology

The transfer of tissue from one anatomic site to another, within the same individual or between individuals, without transfer of the tissue's blood supply.

Graft fixation device

A graft fixation device combination. The device is useful for affixing a tissue graft to a bone or other body surface. The fixation device has two implantation members connected by a graft retention member. The retention member optionally has at least one lateral wing member extending therefrom. The implantation members have longitudinal passageways therethrough. The graft fixation device also has an insertion member extending from the distal end of each implantation member, the insertion member having a longitudinal passage having a distal blind wall. The passages of the implantation members and the insertion members are in communication with each other, and may be mounted onto insertion members.

Placental tissue grafts and improved methods of preparing and using the same

Described herein are tissue grafts derived from the placenta. The grafts are composed of at least one layer of amnion tissue where the epithelium layer has been substantially removed in order to expose the basement layer to host cells. By removing the epithelium layer, cells from the host can more readily interact with the cell-adhesion bio-active factors located onto top and within of the basement membrane. Also described herein are methods for making and using the tissue grafts. The laminin structure of amnion tissue is nearly identical to that of native human tissue such as, for example, oral mucosa tissue. This includes high level of laminin-5, a cell adhesion bio-active factor show to bind gingival epithelia-cells, found throughout upper portions of the basement membrane.

Method and apparatus for use of a self-tapping resorbable screw

A bone attachment apparatus and implantation system. The attachment device provides a screw with channels formed therein for implantation within a bone aperture. The channels are used as a torque transfer surface during implantation, and cooperate with a thread forming tap to enable screw implantation simultaneously with thread formation within the aperture. The tap can be used to form channels within the bone. A staple is coupled to the screw and the bone, utilizing the respective channels formed therein, to prevent rotation therebetween. The screw can also cooperate with the staple to secure a soft tissue graft.

Decellularized grafts from umbilical cord vessels and process for preparing and using same

A tissue graft is disclosed that includes a decellularized umbilical vessel having a luminal surface and an ablumenal surface, wherein the decellularized umbilical vessel is prepared by an automated dissection process. The decellularized umbilical vessel has not been substantially cross-linked. In one method of use, the decellularized umbilical vessel is capable of having at least one cell type seeded at least a portion of at least one of the luminal and ablumenal surfaces thereof. A process of preparing the tissue graft, methods of using the tissue graft, and kits which contain the tissue graft are also disclosed.

Quadriceps tendon stripper/cutter

Instruments and methods that allow for a minimally invasive way to harvest a tissue graft which has been typically done as a full open procedure. The instrument is a hybrid stripper / cutter device provided with both stripping and cutting blades / mechanisms that allow stripping and cutting of the tissue graft with the same hybrid instrument. The present invention also provides a minimally invasive technique for stripping and cutting (resecting) a tissue graft by employing a single, hybrid stripper / cutter instrument. The technique provides a consistently good-quality graft with improved cosmetic results, and is simple and easily reproducible.

Implant placement systems, devices, and methods

Described herein is a simplified placement system and method for a tissue graft anchor by which a surgeon may introduce one or more sutures into a hole in a boney tissue, apply tension to the sutures to advance a soft tissue graft to a desired location, and then advance the anchor into the bone while maintaining suture tension and without introducing spin to the suture.
