Abstract:
The present invention relates to methods and devices for the treatment of disc disease and spinal deformities with an artificial disc replacement.
Abstract:
The present invention relates to a locking mechanism and method of fixation, such a the fixation of a fixation device (104) like a bone screw and of a stabilization device (106 like a rod to the spine. The locking mechanism (100) includes a seat (102) and a locking element (108). The seat includes a bottom portion (114) configured to receive the fixation device (104) such that a socket (116) of the bottom portion (114) engages part of the fixation device (104) and prevents the fixation device (104) from passing entirely therethrough. The seat (106) further includes a side portion (112) configured to receive the stabilization device (106) and a locking element (108). The locking element (108), when fully engaged with the side portion (112) of the seat (102), causes locking of the relative positions of the fixation device (104) and the stabilization device (106).
Abstract:
A tissue shaping device adapted to be disposed in a vessel near a patient's heart to reshape the patient's heart. The device comprises a first anchor (404) and a second anchor (402) adapted to be deployed by a catheter to engage a vessel wall while the first anchor (404) is adapted to resist the compression of a first part (502) of the first anchor and resist the expansion of a second part (504) of the first anchor (404) in response to a compressive force on the first part (502), wherein the first anchor (404) has a deployed configuration in which its width is greater than its height
Abstract:
An artificial disc prosthesis is provided. The prosthesis of the present invention enables spinal segment alignment by having a variable height across its surface. The variable height is achieved by an asymmetric artificial nucleus or by at least one variable height end plate.

Abstract:
Described is a locking mechanism and method of locking the relative positions of a fixation device (104) like a bone screw and of a stabilization device (106) like a rod. The locking mechanism includes a seat (102), a washer (108) and a cap (110). The seat (102) includes a bottom portion (114) configured to receive the fixation device (104) such that a socket (116) of the bottom portion (114) engages part of the fixation device (104) and prevents the fixation device (104) from passing entirely therethrough. The seat (102) further includes a side portion (112) configured to receive the stabilization device (106), a washer (108) and a cap (110). When the washer (108) and cap (110) are fully engaged with the seat (102), the fixation device (104) may be locked independent of the stabilization device (106). The locking mechanism may also include a locking element for locking the stabilization device (106).
