Publication number: 20060036313Abstract: An improved apparatus and method for AAC insertion including a new AAC connector having a threaded or partially threaded body. The AAC connector has a flexible flange situated at one end that is soft and thin enough to bend backwards so that it can be pushed through an opening made in the apex, but rigid enough to flex back to its original position and hold its shape once it enters the interior of the left ventricle. A second ring is also provided that is adapted to be deployed over the body of the connector and against the exterior wall of the apex.Type: ApplicationFiled: August 11, 2004Publication date: February 16, 2006Inventor: Thomas Vassiliades

Patent number: 6730021Abstract: A retractor with devices that allow a surgeon to control the amount of retractor force. The retractor may include a first blade and a second blade. The second blade can be moved by a gear mechanism. A torque measuring device, force measuring device and/or slip clutch may be coupled to the gear mechanism. The torque measuring device may have a readout that displays the amount of torque being applied by the surgeon to the retractor. The readout provides accurate feedback that allows the surgeon to gauge the amount of force being applied to the patient. Likewise the force measuring device may provide a visual indication of the actual force being applied by the retractor onto the patient. The slip clutch may actuate at a threshold torque to prevent an excessive exertion of force on a patient.Type: GrantFiled: November 7, 2001Date of Patent: May 4, 2004Assignee: Computer Motion, Inc.Inventors: Thomas A. Vassiliades, Jr., Jim Deacon
