摘要:
A clamp housing assembly and method for providing stabilization as a bone anchor during an operation. The assembly includes a housing, a locking element and a band. The housing defines a longitudinal axis, a center recess, and at least one slot. The housing has two opposing arms extending from a base. At least a portion of the inside surface of each arm may be threaded and at least a portion of the outside surface of each arm may be planar. The locking element is positionable within the recess in a co-axial relationship to the housing. The band is sized for travel along a predetermined path defined in part by the at least one slot in the housing.

摘要:
An apparatus and a method for occluding an aperture within a body surface, including an occlusion bag having a proximal sac and a distal sac, a delivery catheter, a guide catheter, a super-elastic wire, a release mechanism and a delivery sheath. The method of the invention includes affixing the delivery catheter to the proximal sac and then inserting the guide catheter into the delivery catheter. The super-elastic wire is attached to the release mechanism and the wire, release mechanism, occlusion bag, guide catheter and delivery catheter are inserted into a delivery sheath for transport to the aperture. After delivery, the occlusion bag is placed within the aperture and the wire is deployed within the bag. The bag and wire are repositioned if necessary, and the release mechanism is activated to release the wire. The guide catheter, delivery catheter, release mechanism and delivery sheath are then withdrawn.
摘要:
A spinous process fixation assembly and method for securing adjacent spinous processes. The assembly includes one or more lateral plates engageable with one or more insertion plates, respectively. The one or more lateral plates may include a material collection zone for insertion of biologic material prior to implantation. One lateral plates may be rotatable with respect to an adjacent lateral plate. One lateral plates may be movable with respect to an adjacent lateral plate between an extended and a compressed position. A single fixation device may be used to secure spinous processes across two or more levels and promote distraction at each level.
