20090318928 | Method and Device for Inplant Deployment - A surgical implant insertion system for deployment and removal of an implant into a vertebral body. The system includes an actuation rod, an actuator handle coupled to the actuation rod, and an inserter locking tube disposed over the actuation rod and coupled to an inserter handle. Upon insertion of the implant into the vertebral body using the inserter handle, the actuator handle is turned causing the actuation rod to expand or compress the implant disposed at a distal end of the inserter locking tube. | 12-24-2009 |
20120245691 | EXPANDABLE INTERBODY SPACER - An expandable intervertebral spacer includes a body, a proximal end, and a distal end. The body includes quadrants that form a substantially cylindrical shape in a first configuration and a substantially cuboidal shape in a second configuration. Each quadrant includes a ramp portion with a ramp and a landing and a sliding portion with a sliding side and a foot. The ramp portion of a first quadrant engages the sliding portion of a second quadrant. The proximal end and the distal end couple with the plurality of quadrants and transfer an actuating force to expand the body from the first configuration to the second configuration. | 09-27-2012 |
20140094860 | EXPANDABLE SCREW AND METHODS OF USE - An expandable screw includes generally a shaft, a head, and a cut pattern. The shaft includes a longitudinal axis, an outer surface including a thread to engage bone, and an expandable region configurable between a first state with a first radius measured from the longitudinal axis to the outer surface and a second state having a second radius measured from the longitudinal axis to the outer surface. The head coupled with the shaft at a neck is configured to receive a driving instrument to insert and drive the shaft into the bone when the expandable region is in the first state. The cut pattern on the shaft permits at least partial nesting of a first portion of the expandable region within a second portion of the expandable region in the second state. | 04-03-2014 |
20140316212 | SYSTEMS AND METHODS FOR TISSUE RETRACTION - A system for interchangeable retractor blades includes a shell, a first retractor blade, and a second retractor blade. The shell includes a rigid proximal end configured to attach to a surgical retractor and an opening, a distal closed end, and a pliable portion including a pocket in communication with the opening and extending along a length of the shell to the distal closed end. The first retractor blade includes a first geometry received through the opening into the pocket and that shapes the pliable portion to configure the shell in a first configuration. The second retractor blade includes a second geometry received through the opening into the pocket and that shapes the pliable portion to configure the shell in a second configuration. | 10-23-2014 |
20150045626 | Blade Attachment and Adjustment Mechanism for Tissue Retraction - A blade assembly for a tissue retractor includes a blade, a mount, and a positioner member. The blade includes a length extending from a proximal portion with a coupling to a distal portion for retracting soft tissue. The mount includes a receiving portion that receives the coupling. The positioner member is rotatably coupled to the mount and engages the proximal portion to apply a force that positions the blade relative to the mount. | 02-12-2015 |
20150230835 | INTERSPINOUS PROCESS SPACER APPARATUS AND METHODS OF USE - An interspinous process spacer includes a main body, a first wing, and a screw. The main body includes a first securing member extending from a top portion of the main body that engages a first vertebra and a bottom portion of the main body that engages a second vertebra. The first wing pivotably couples to a distal portion of the main body and includes a second securing member extending parallel to the first securing member to form a first clamp. The screw is positionable within the main body and includes a distal end that positions the first wing between a first position and a second position. The first clamp includes a first diameter in the first position and a second diameter in the second position. | 08-20-2015 |
20150359572 | SINGLE ACTION LOCKING PEDICLE SCREWDRIVER - An instrument for attaching a driver shaft to a screw assembly using a thrusting motion. The instrument has a main shaft, a locking tube, and a driver shaft. The locking tube is slidably mounted within the main shaft and the driver shaft is slidably mounted within the locking tube. The locking tube is configured to urge a jaw assembly of the instrument into a tensioned engagement with a body member of the screw assembly. A locking mechanism is also included and is configured to lock the driver shaft in a fixed position relative to the locking tube. The locking mechanism may be configured to lock the driver shaft with respect to the locking tube after a distal end of the main shaft engages the screw assembly using the single action. | 12-17-2015 |
20160095638 | ORTHOPEDIC SCREW - An orthopedic screw having a shaft and a thread ribbon is provided. The shaft includes a proximal driving end and a distal end. The thread ribbon extends around the shaft and including a base portion that is rigidly attached to the shaft and a flange portion that is resilient. The flange portion extends away from the shaft at a preset angle to form a preset outer thread diameter in a preset configuration. The flange portion extends away from the shaft at a second angle greater than the preset angle to form a second outer thread diameter greater than the preset outer thread diameter when the orthopedic screw is subjected to a pull out force. | 04-07-2016 |
