A bone fusion implant system including a first implant body having substantially flat top and bottom surfaces for engaging opposing vertebrae and a side wall extending between the top and bottom surfaces, the side wall including a concave recess and a second implant body having substantially flat top and bottom surfaces for engaging the opposing vertebrae and a side wall extending between the top and bottom surfaces thereof, the side wall of the second implant including an arcuate portion adapted to be received within the concave recess for enabling the first and second implant bodies to be positioned in nested side-by-side relation between the opposing vertebrae.

Low profile fusion cage and insertion set

A valve assembly is provided for permitting the introduction of a surgical instrument into a patient's body while providing a substantial seal about the instrument. The valve assembly includes a sealing gasket assembly providing a fluid tight seal before instrument insertion, and is configured and dimensioned for accommodating an instrument and providing a substantial fluid tight seal after insertion of an instrument. The valve assembly may further include a deformable sealing member having a substantially central aperture for accommodating the instrument. The sealing member provides a substantial seal about the instrument when the instrument is passed therethrough impeding the egress of fluids and gasses through the valve assembly.

Valve assembly for introducing instruments into body cavities

A bone fusion implant includes a rigid body having a distal end, a proximal end and a longitudinal axis extending between the distal and proximal ends and a concave channel formed in the body between the distal and proximal ends, the concave channel being formed about an axis extending in a direction substantially perpendicular to the longitudinal axis of the body. The body has a first rigid cylindrical outer wall extending between the distal end of the body and the concave channel and a second rigid cylindrical outer wall extending between the proximal end of the body and the concave channel. The body also has a first opening at the distal end, a second opening at the proximal end and a hollow, internal chamber extending between the first and second openings.

The invention is a single piece, self seating and locking dynamic intervertebral spacer. The dynamic spacer is load-supporting but also able to undergo flexure in either or both the lateral and sagittal planes.

Seal assembly

An apparatus for facilitating fusion of adjacent bony structures includes an implant body dimensioned for positioning between adjacent bone structures to maintain the bone structures in desired spaced relation during interbody fusion. The implant body has an outer wall and an external threaded configuration disposed on the outer wall. At least one concave surface at least partially extends along the implant body. The concave surface advantageously reduces the transverse cross-sectional dimension of the implant member thereby facilitating placement of the implant member in restricted intervertebral areas. In addition, the concave surface enables placement of a pair of implants in nested side-by-side relation. Preferably, the threaded configuration has portions removed along an arc section of the outer wall thereby defining a series of generally longitudinally aligned concave surfaces in individual turns thereof. A system and method for facilitating fusion of adjacent vertebrae is also disclosed.

Apparatus for fusing adjacent bone structures

An apparatus for facilitating fusion of adjacent vertebrae, In one preferred embodiment, the apparatus for facilitating fusion of adjacent vertebrae includes a retractor and a retractor introducer. The retractor includes a retractor sleeve having proximal and distal ends and defines a longitudinal passageway for reception of surgical instrumentation. The retractor sleeve has first and second retractor arms extending distally therefrom in a general longitudinal direction. Each retractor arm has first and second opposed supporting surfaces for engaging respective adjacent opposed vertebrae. Each retractor arm defines a dimension between the first and second supporting surfaces sufficient to distract the opposed vertebrae upon insertion thereof. The retractor introducer is positionable within the longitudinal passageway of the retractor sleeve. The retractor introducer includes an elongated member defining proximal and distal ends and having a distal introducer head. The introducer head has a retractor arm insert. The retractor arm insert preferably defines a cross-sectional dimension to substantially occupy the inner area defined by the retractor arms of the retractor and possesses sufficient rigidity to advance within the tissue portions thereby facilitating placement of the first and second retractor arms of the retractor between the vertebral portions in distracting engagement therewith. The introducer head of the retractor introducer may also define a proximal portion which has a cross-sectional dimension generally corresponding to the internal dimension of the retractor sleeve to thereby substantially minimize entry of tissue within the retractor sleeve during placement between the opposed vertebrae. Preferably, the cross-sectional dimension of the proximal portion of the introducer head is slightly less than the internal dimension of the retractor sleeve.

Method and apparatus for spinal implant insertion

A laparoscopic surgical retractor for use during a laparoscopic spinal procedure, includes an elongated sleeve member having proximal and distal end portions and defining a longitudinal opening therethrough and a valve assembly mounted to the proximal end portion of the elongated sleeve member for sealing a surgical instrument introduced within the longitudinal opening of the sleeve member. The distal end portion is configured for insertion at least partially into an intervertebral space between adjacent opposed vertebrae to distract the adjacent vertebrae. A method for inserting a fusion implant with the use of the retractor is also disclosed.

Method and instrumentation for implant insertion

An apparatus for applying a tissue fastener for fastening soft tissue to bone includes elongated members, one of which holds a loading unit having a tissue fastener mounted therein, and another of which is moved to expel the tissue fastener from the loading unit and expand legs of the tissue fastener to secure it within a predrilled hole in bone. The tissue fastener is preferably a two piece fastener including a body portion with legs flexibly expandable by a setting pin. The loading unit engages both the body and the setting pin.

Tissue fastener implantation apparatus and method

A method for percutaneous dissection of a segment of vascular tissue from a patient is provided which includes providing an elongated tubular member having a proximal end and a distal end, and blunt dissection structure positioned adjacent the distal end of the tubular member and remotely actuable from adjacent the proximal end of the tubular member. The method further provides for percutaneously accessing a first end portion of the vascular tissue segment, the blunt dissection structure is positioned adjacent the vascular tissue segment and is actuated to bluntly dissect the vascular tissue segment from surrounding body tissue.

Surgical dissector

An apparatus is disclosed for endoscopic application of surgical staples in laparoscopic hernia surgery. The apparatus includes a handle and a generally elongated endoscopic section connected to the handle and extending distally therefrom. A staple storage magazine is provided for storing a plurality of surgical staples at the distal end portion of the endoscopic section. The staple storage magazine is pivotable between a first position in alignment with the longitudinal axis of the endoscopic section and a second position at an acute angle to the longitudinal axis. An elongated pusher system is provided for individually advancing at least one staple at a time distally. A trigger mechanism is provided to actuate the pusher.

Apparatus and method for applying surgical staples to attach an object

A method and apparatus for closing a punctured blood vessel is described. The method includes providing a clip applier adapted to apply one or more surgical clips to at least a portion of the exterior of a blood vessel in order to close a puncture wound therein. In a preferred embodiment, the clip applier is guided to the puncture by a guide wire and one or more surgical clips are applied to close the puncture wound.

Vascular hole closure

A tagging device for marking the location of lesions within the body prior to a surgical procedure such as excision or biopsy. The device includes an elongated tube having one end supported on a housing and a second end extending distally therefrom. An anchor is positioned within the distal end of the elongated tube and has an elongated member extending proximally therefrom. An actuation assembly including a plunger is movable within the tube to engage and push the anchor from the distal end of the tube. The anchor and the actuation assembly are positioned and configured such that the anchor is pivoted from a position parallel to the longitudinal axis of the tube to a position perpendicular to the longitudinal axis of the tube as it as being pushed from the tube.

Tissue tagging device

A surgical apparatus is provided which includes a handle portion and an elongated body portion extending distally from the handle portion and defining a longitudinal axis.
