... by the longitudinal deformation of a skeletal muscle. The compliant mechanism is designed to impose controlled shear and compressive strain to the growing joint construct in order to initiate cartilage formation. The paper emphasizes the conceptual design and its rationale. Evaluation using finite element analysis...

...Katya Christenson; Joseph Jacquemin; Steven Fannon; Davina Widjaja; Kathleen H. Sienko; Ronald Chervin Obstructive sleep apnea is a common sleep disorder in which throat muscles relax during sleep, causing the upper airway to close. As a result, breathing ceases until a brief awakening restores...

The proposed device guides the knee through cyclic...

... specially designed “anchor” structures that are utilized to attach on the muscle tissue during measurements to minimize the effect of muscle contractions on sensor readings. Electrical isolation of the wire bonds and bonding pads has been accomplished by utilizing glob-topping technique. The fabricated...

To validate this design goal, muscle moment arms were measured in three cadaver elbow specimens using the simulator. Flexion-extension moment arms...

... muscle was used as a model for the in vitro study. Q-switched 532 nm laser (GreenLight PV, American Medical Systems, MN) was used and the laser was allowed to scan over the tissue with controlled speed and working distance, distance from the tip of the optical fiber to the tissue's surface. Injury...

The forces applied to and the position of the supports are monitored and used to control motors attached to the gas springs. This means that the user can, when required, be returned to their original position...
