摘要:
A method for postoperative use of an adhesion prophylactic. After an operation that might have to be repeated, a non-reabsorbable membrane, made of material that is compatible with a body, is placed between an operation site and adjacent tissue. The membrane is configured such that during a repair operation the membrane can be used to facilitate exposure of the operation site.

An intervertebral implant, alone and in combination with an insertion tool for inserting same and a method for inserting same. The implant has upper and lower parts which have universal movement relative to each other. Each of the upper and lower parts also has a surface engaging an adjacent vertebrae. Each part has a keel extending from said surface into a cutout in the adjacent vertebrae, and each keel has an anterior opening recess therein. An insert tool has a pair of arms which are received in the recess of the keels through the anterior opening to securely hold and insert the implant. Projections and matching indentations in each arm and the base of its recess securely attached each arm within its keel.

An intersomatic implant (1a, 1b) maintains bone graft material in a receiving cavity formed in a disc in order to obtain intervertebral fusion. The implant (1a, 1b) includes of a plurality of parts provided with means for in situ connection of two consecutive parts. Instruments (33) are used to connect these implants (1a, 1b) and a tool assists in introducing these implants (1a, 1b) into the cavity formed in the disc.

Instruments and methods for preparing an intervertebral space for receiving an implant. An adjustable trial implant has an adjustable stop mechanism having a stop member connected thereto to vary the distance that a body portion of the trial implant can move into the intervertebral space. Cutting tools for forming cutouts in the adjacent vertebrae use the trial implant and/or a guide to position a cutting tool which may be a burr or a chisel. The chisel cutting tool can be moveable relative to a selected trial implant or the chisel cutting tools can be fixed onto a trial implant shaped body portion.

摘要:
Disclosed is an implant holder for an implant device comprising a locking mechanism that in a first position causes a clamp coupled to an implant device to lock such that the clamp cannot be decoupled from the implant device, and in a second position causes the clamp to unlock the implant device such that the clamp remains coupled to the implant device in the absence of a sufficient decoupling force but is decoupled from the implant device in the presence of a sufficient decoupling force. Also disclosed are methods of implanting an implant device using an implant holder by coupling the implant device to the implant holder, locking the implant device and the implant holder, emplacing the implant device utilizing the implant holder, unlocking the implant device and the implant holder such that the implant device is still coupled to the implant holder but can be decoupled with sufficient force.

A bi-directional suture passing instrument configured to approach soft tissues perpendicularly, enables safer and more efficient surgical repairs and minimally invasive techniques to be employed, useful in areas such as annulus repair, meniscal repair, shoulder arthroscopy, hernia repair, laproscopic repair, and wound closure.
摘要:
Instruments and methods for inserting an intervertebral implant. Insertion of the implant is accomplished by grasping the implant between the arms of an insertion instrument having arms which separate from each other and close against each other onto the implant, such that the ends of the arms of the insertion instrument engage recesses of the implant. A spacer may be provided between the arms of the insertion instrument to help position the implant while held by the arms.
摘要:
A movable intervertebral disc prosthesis having a pivot point and adapted to be implanted between vertebra bodies to form a vertebrae segment. In an implanted state three-dimensional movement axes of the vertebrae segment intersect in the pivot point. The configuration of the prosthesis is such that a deliberate displacement or shifting of the pivot point can be carried out prior to, during and/or after the implantation.
