| 20100168865 | ASSEMBLY FOR USE IN IMPLANTATION OF A JOINT COMPONENT - An assembly for use in a procedure for implantation of an orthopaedic joint component, comprises a head part of the joint component which has a tapered bore within it, and a connector part which is tapered inwardly along its length so that it can be received snugly in the tapered bore in the head part, the connector part having a bore within it. A tool includes a spigot which fits snugly into the bore in the connector part. Each of the tool and the connector part has a face which contact one another when the spigot on the tool is fully received in the bore in the connector part, and in which each of the said faces extends generally transverse relative to the aligned axes of the spigot and the bore. | 07-01-2010 |
| 20110276053 | METHOD OF USING AN ALIGNMENT GUIDE - A method of aligning an alignment guide relative to a reamed acetabulum of a patient is provided. The method includes the step of manipulating an alignment guide comprising a shaft having a longitudinal axis and a guide arm having a first portion, a second portion and a third portion, the first portion attached to the shaft and configured to be rotatable about a first axis substantially perpendicular to the longitudinal axis, the second portion extending from the first portion at a first predetermined angle along a second axis, and the third portion extending from the second portion at a second predetermined angle. The guide arm is rotated about the first axis relative to the shaft. A cup or trial is attached to the distal end of the shaft and positioned to contact the reamed acetabulum. The third portion of the guide arm is then oriented with respect to the long axis of the patient and the surface of the table on which the patient is positioned. | 11-10-2011 |
| 20110276100 | ALIGNMENT GUIDE - An alignment guide is provided having a shaft with a longitudinal axis and a guide arm having a first portion, a second portion and a third portion. The first portion is attached to the shaft and configured to be rotatable about a first axis substantially perpendicular to the longitudinal axis. The second portion extends from the first portion at a first predetermined angle along a second axis. The third portion extends from the second portion at a second predetermined angle. | 11-10-2011 |

| 20080228188 | SURGICAL GUIDE - A surgical guide and computer aided surgery method of use thereof are described. The guide is mounted on a body part to guide a device along a guide axis. The body has a channel in it which defines the guide axis and which receives the device in use. A base engages the surface of the body part when mounted on it in use, and supports the body over an entry point for the body part with the guide axis passing through the entry point. A pivot mechanism attaches the body to the base. The body can move relative to the base by pivoting only. The guide is configured such that the entry point is a centre of motion about which the body pivots. | 09-18-2008 |
| 20080255584 | Acetabular Cup Positioning - A computer aided surgery system, method, surgical method and instrument for guiding the positioning of an acetabular cup in a pelvis are described. The position of the transverse acetabular ligament of the pelvis and the position of the acetabular labrum of the pelvis are determined. The orientation of an acetabular plane including the acetabular labrum and the transverse acetabular ligament is calculated. A planned position for the acetabular cup is determined, in which an inlet plane of the cup is substantially parallel to the acetabular plane. The instrument comprises a mounting for attaching the instrument to a patient, a support, a guide defining a longitudinal axis, and for receiving a further instrument bearing the acetabular cup implant, and an adjustment mechanism. The adjustment mechanism can allow the angular orientation of the guide to be adjusted about at least two different axes to allow the inclination and version or anteversion of the longitudinal axis to be altered. | 10-16-2008 |

| 20120069003 | Method and System for Evaluation Using Probabilistic Boosting Trees - A method and system for evaluating probabilistic boosting trees is disclosed. In an embodiment, input data is received at a graphics processing unit. A weighted empirical distribution associated with each node of the probabilistic boosting tree is determined using a stack implementation. The weighted empirical distribution associated with each node is added to a total posterior distribution value. | 03-22-2012 |
