Abstract: In some embodiments, the present invention provides a reverse shoulder glenoid prosthesis which supports the attachment of multiple different types of modular attachments that can: 1) provide additional scapular fixation (ie external to the glenoid) in order to improve glenoid implant fixation in cases of severe bone loss/fracture, 2) provide joint line lateralization to improve tissue stability in cases of severe glenoid/scapula bone loss, 3) facilitate use and containment of glenoid bone graft in cases of severe glenoid/scapula bone loss—particularly in those cases in which the glenoid defect is uncontained/peripheral 4) achieve glenoid fixation while at the same time reconstructing the scapular bone in cases of scapula fractures, glenoid fractures, and/or acromial fractures, and 5) provide improved rTSA joint biomechanics, particularly posterior rotator cuff efficiency by changing the line of action of the infraspinatus and teres minor muscles to improve their muscle tension, and also increase each muscle'

Abstract: A cooling system includes a coolant tank, a coolant sensor assembly, and a controller. The coolant sensor assembly includes a sensor package having a first end and a second end, the sensor package including a partially transparent or semi-transparent sight glass housing a coolant level sensor and configured to receive a flow of coolant therethrough. The coolant sensor assembly also includes a first valve coupled between the first end of the sensor package and a coolant tank, a second valve coupled between the second end of the sensor package and the coolant tank, and a third valve coupled in flow communication with the second end of the sensor package. The controller is configured to execute one more diagnostic self-tests for the coolant sensor assembly and the cooling system.
