A mandible endoprosthesis implant (10), comprising: first element (100) extending along first element x-axis & including an accommodation recess and first insertion hole extending along a first element z-axis transverse to the first element x-axis; second element (200) includes and second insertion hole through a protrusion; the protrusion and recess are engageable with the insertion holes aligned; a fastener (300) which, when the protrusion and the accommodation recess are engaged, is fixedly attachable to the first coupling portion (100). Clearances between coupling portions of the elements (100,200) and between the fastener (300) and coupling portion of the second element (200) allow the first and second elements (100, 200) to pivot about the first element z-axis and/or a first element y-axis, which extends transverse to the first element x- and z-axes, by a maximum angle in a range from 0.01 to 10 degrees.
摘要:
The present disclosure relates to a surgical device, such as a surgical implant, which may be used in several types of procedures. More specifically, the present disclosure relates to implants for use in an anterior, posterior, posterior lateral or direct lateral approach to the disc space. The surgical device may be manipulated in various manners to accommodate delivery through a minimally invasive portal in one configuration and adjusted to a second configuration once placed in the intervertebral space. A delivery system for placing the surgical device in a body is also disclosed.

Injection-molded devices and systems for graft or other tissue delivery, methods for their single-use in delivery of an implant, and kits for their sterile delivery to a practitioner are disclosed herein. Systems for implant delivery comprise an injection moldable implant body and an insertion device comprising: an inner and outer shaft that form a locking mechanism that secures an implant body in place and releases it upon placement within a patient. Systems are configured to be manufactured by injection molding, such that they can be cost-effectively manufactured and discarded after a single use to avoid costs and risks associated with re-sterilization and cleaning, but can in some cases optionally also be manufactured by machining to be re-sterilized and reused.

An expandable interbody fusion device includes superior and inferior endplates that are configured to receive a sequentially inserted stack of expansion members or wafers in interlocking engagement. The expansion members are formed to each have a generally U- shaped rearward facing opening. The superior and inferior endplates have openings through their outer surfaces in at least partial alignment and communication with the rearward facing openings of the expansion members. The inferior endplate has a fully bounded cavity for telescoping receipt of the superior endplate. The inferior endplate also has a fully bounded channel extending through the rear endwall thereof in direct communication with the rearward facing opening of at least one expansion member for the receipt of bone graft material into the device to promote fusion between opposing vertebral bodies of the spine.

A device and method for improving hydration of a biomaterial includes a syringe (18) having a cavity (22) therein and a distal opening (26), an end cap (28), and a wall (36) operatively coupled to the end cap (28). The end cap (28) has a distal plate (34) with an inlet and is removably attached to the syringe (18) to cover the distal opening (26). The wall (36) is positioned proximate to the inlet and at least partially defines a volume in fluid communication with the inlet. An orifice (76) extends through the wall (36) and fluidly connects the volume to the cavity (22). A flow of a liquid component (14) of biomaterial diffuses through the orifice and is introduced into a particulate component (12) of biomaterial. As such, the liquid component (14) of biomaterial hydrates the particulate component (12) of biomaterial.

摘要:
Coiled spinal implants (10) for disc, vertebral body, and spinal motion segment replacement or reconstruction comprise a plurality of loops (16) and spaces between the loops, with the loops formed of a hollow material and having a plurality of apertures (24) or a longitudinal gap (26) that extend or extends through the sidewalls (20) of the loops (16) and into the hollow center. The coiled implants (10) include one or more balloons (30) within the hollow center, the spaces (18) between the coil loops (16), and/or within the central void (19) that the coil (10) surrounds. Filling the balloon (30) expands the loops (16) and thereby increases the height of the coil (10). Bone graft material or bone cement may be deployed from the apertures (24) or gap (26).
摘要:
An intervertebral cage and intervertebral cage apparatus (1100) and a method for using the intervertebral cage and/or the intervertebral cage apparatus (1100). The intervertebral cage can be any desired material including a memory material. The intervertebral cage apparatus (1100) include the intervertebral cage and can include a deployment system one or both of a variable volume pouch (406) and a deployment cable (806). The variable volume pouch (406) can be inserted into an internal volume of the intervertebral cage and affixed to the intervertebral cage. The variable volume pouch (406) can be filled with material to achieve an expanded state. The variable volume pouch (406) can assist in the deployment of the intervertebral cage. The deployment cable (806) can be attached to the intervertebral cage and can include features to facilitate that attachment. The deployment cable (806) can apply a force to the intervertebral cage to deploy the intervertebral cage, and can include features to lock the intervertebral cage in the deployed configuration. An implantation tool can be used to apply force to the intervertebral cage to deploy the intervertebral cage.
摘要:
The present application is directed to the field of implants comprising processed hard or soft biological tissues for use in implantation in humans. The molded biological tissue implants of the present application are preferably made from allograft soft tissue sources and demineralized bone matrix. The present application provides biological implants exhibiting advantageous properties of absorption, expansion, resiliency and shape retention. The properties of the biological implants produced by the methods of the present application are leveraged in the creation and development of novel biological implant constructs and of novel methods of treatment and surgical technique.
