摘要:
A dental mesh for covering a membrane material and a bone graft material filling the tooth socket includes a mesh and a plurality of attachment needles. The mesh is substantially rectangular, and each needle has an end having a pointed tip and an opposite end connected to the mesh. The attachment needles are curved such that the pointed tips of paired attachment needles face each other or downwardly to respectively penetrate into the opposite gum tissues for securing the mesh to the gum tissues. The attachment needles are connected to strands extending from the mesh. The attachment needles may be “J”-shaped, compound curved, “C”-shaped or “L”-shaped. The mesh further includes a plurality of protrusions, which extend and taper downwardly from the mesh in order to penetrate into the membrane for preventing the membrane from moving.

A methodology for grafting together adjacent bony structures is provided using an implant device having an endplate with an inner disc portion and outer ring portion spaced from the inner disc portion by a connecting wall disposed there between. An endplate interior surface includes a retaining structure for securing the endplate to one of the bony structures, and endplate an exterior surface has an integrally formed socket. A ball-joint rod has a longitudinally extending body and an end, and at least a portion of the ball-joint rod end is curvilinear in shape. The curvilinear ball-joint rod end is rotatably disposed in the endplate socket to fixedly interconnect the bony structures.

Devices and methods for in situ drawing, filtering and seeding cells from the marrow of surrounding bone into a fusion cage without any of the challenges mentioned above. Various implants and devices with aspiration ports that enable in-situ harvesting and mixing of stem cells. These devices may include spinal fusion cages, long bone spacers, lateral grafts and joint replacement devices. Each device utilizes at least one aspiration port for harvesting of stem cell-containing marrow via aspiration from adjacent bony elements.
摘要:
A covering for delivering a substance or material to a surgical site is provided. The covering, with substance provided therein, may be referred to as a delivery system. Generally, the covering may be a single or multi-compartment structure capable of at least partially retaining a substance provided therein until the covering is placed at a surgical site. Upon placement, the covering may facilitate transfer of the substance or surrounding materials. For example, the substance may be released (actively or passively) to the surgical site. The covering may participate in, control, or otherwise adjust, the release of the substance.

摘要:
A clamp for a linkage for linking first and second bone fasteners of a prosthesis assembly, the clamp comprising a clamp body having a first receiving portion for receiving a first component of a prosthesis assembly and a second receiving portion for receiving a second component of the prosthesis assembly, the clamp having a deflectable member which deflects from a first position to a second position when one of the first and second components is introduced to its corresponding receiving portion, wherein when the deflectable member is in the second position and the other one of the first and second components is received by the clamp, the deflectable member is engageable with said other one of the first and second components.
摘要:
An apparatus for automated implantation of an implant or for an automated augmentation process of hard tissue and/or hard tissue replacement material using a sheath element is provided. The apparatus comprises a casing, a converter operable to generate mechanical vibrations the converter inside the casing and displaceable in a longitudinal direction relative to the casing, and a sonotrode coupled to an output location of the converter. A shaft portion with a retention structure is rotationally coupled to the casing and is equipped for cooperating with a rotationally asymmetric element of the sheath element to rotationally couple the casing to the sheath element. An axial coupling is equipped for locking the casing to the sheath element. The shaft portion, the axial coupling and the sonotrode are mutually arranged so that the a distal end of the sonotrode may be introduced into a longitudinal opening of the sheath element.
摘要:
A medical that is implantable into a human or animal body or being an augmentation device for strengthening human or animal hard tissue for subsequent implantation of a separate implant. The device includes a sheath element suitable of being brought into contact, during a surgical operation, with live hard tissue and/or with hard tissue replacement material. The sheath element has a, for example, generally elongate shape and a longitudinal bore defining a longitudinal opening reaching from a proximal end of the sheath element into a distal direction, and a plurality of holes in a wall of the opening. Further, the device includes a liquefiable element that is insertable or inserted in the longitudinal opening and at least partly liquefiable by the impact of energy impinging from the proximal side.
