摘要:
A multi-lumen mold is for the in situ formation of a prosthesis in an annulus located in an intervertebral disc space of a patient. The annulus has at least two openings formed by minimally invasive techniques and at least a portion of the nucleus pulposus is removed to form a nuclear cavity. The multi-lumen mold includes a mold adapted to be located in the nuclear cavity. A first lumen having a distal end is fluidly coupled to a flexible mold at a first location. At least a second lumen having a distal end fluidly coupled to the flexible mold at a second location. The first and second lumens are adapted to extend out through the openings in the annulus when the mold is positioned in the nuclear cavity. One or more securing members can be used to secure the mold in the intervertebral disc space. The securing members can engage with the annulus, the end plates, and/or another surface of a vertebrate.
摘要:
A method and apparatus for fluidly coupling a reservoir containing a flowable biomaterial to a mold. The flow of the flowable biomaterial into the mold is controlled in accordance with a first operating parameter. At least one injection condition is monitored. The flow of the flowable biomaterial is controlled in accordance with a second operating parameter in response to one or more of the injection conditions reaching a threshold level. The second operating parameter is maintained during at least a portion of the curing of the flowable biomaterial. In some embodiments, the second operating parameter may optionally include permitting a portion of the flowable biomaterial to be expelled from the mold.

摘要:
A method of stabilizing adjacent vertebrae including the steps of forming at least one annulotomy in an annulus. At least a portion of the nucleus material is removed through the annulotomy to form a cavity in an intervertebral disc space between the adjacent vertebrae. A reservoir containing a flowable biomaterial is fluidly coupled to the intervertebral disc space. A flowable biomaterial is delivered to the cavity. The delivery of the flowable biomaterial into the intervertebral disc space is controlled in accordance with at least a first operating parameter. The biomaterial is at least partially cured to stabilize the adjacent vertebrae.

摘要:
A multi-lumen mold is for the in situ formation of a prosthesis in an intervertebral disc space located between adjacent vertebrae of a patient. The multi-lumen mold a flexible mold, a first lumen, a second lumen and a curable biomaterial. The flexible mold is shaped to be positioned in the intervertebral disc space. The first lumen and the second lumen each have a distal end is fluidly coupled to the flexible mold at a first location and a second location, respectively. The first lumen is shaped to extend out through a first opening extending through one of the adjacent vertebrae when the mold is positioned in the intervertebral disc space. The curable biomaterial is delivered into the flexible mold through at least one of the first and second lumens. The first and second locations can optionally be located on generally opposite sides of the mold, on the same side of the mold, or a variety of other configurations. One or more securing members can be used to secure the mold in the intervertebral disc space. The securing members can engage with the annulus, the end plates, and/or another surface of a vertebrae.
