Appl. No.:

12/646571

Inventors:

Wagdy W. Asaad - Oak Brook IL, US
Steven E. Mather - Hinsdale IL, US

Assignee:

Spinecraft, LLC - Westchester IL

International Classification:

A61B 17/70

US Classification:

606252, 606250, 606251

Abstract:

Transconnector devices and methods of use are provided. A transconnector device has the capability of connecting to elongate spinal fixation elements having various cross-sectional dimensions. The transconnector device is adjustable in three degrees of freedom and is curved to ensure that it maintains a minimum distance posterior of the dura when it is fixed to elongate spinal fixation elements.

Wagdy W. Asaad - Burr Ridge IL, US

International Classification:

A61B 17/88

A61B 17/80

US Classification:

606281, 606286, 606289, 606104

Abstract:

A surgical plate system, components and methods of using are described. A surgical plate system includes a plate having an anterior surface, a posterior surface, a longitudinal axis, a transverse axis and a through hole passing through the anterior and posterior surfaces. A variable fastener is configured and dimensioned to connect to the plate, the variable fastener having a head and a shaft extending distally from the head. The head is configured to assume different proximal end diameters. The head, in a first configuration allows inward flexing to reduce a diameter of the head to allow the head to pass through an entrance opening of the through hole. In a second configuration, the head is prevented from flexing inwardly thereby preventing the head from backing out of the entrance opening, while allowing articulation of the head, within the through hole, relative to the plate.

US Classification:

606279, 606246

Abstract:

Systems and method for fixation to a spinal column are described. A system includes a plate having an anterior surface, a posterior surface, a longitudinal axis, a transverse axis and a through hole passing through the anterior and posterior surfaces; and a dynamic fixator interface member configured and dimensioned to connect to the plate within the through hole and to axially slide relative to the plate in directions of the longitudinal axis, and additionally, to rotate relative to the plate in directions about the transverse axis.

International Classification:

A61B 17/34
A61B 90/30
A61B 17/70

Abstract:

An access port for minimally invasive surgery includes an elongate, tubular main body portion, a slot extending over a length of the main body portion in a lengthwise direction, and a flap which covers the slot in a closed configuration, while exposing the slot when in an open configuration. The slot extends through a wall of the main body portion, from an outside surface of the main body portion to an inside surface of the main body portion.
