Patent number: 6810758Abstract: Provided is a test system and method that permits automatically interchanging a plurality of tools to seamlessly perform various functions on a sample. Each tool is mounted in an assembly and the sample is mounted on a chuck. A path is defined in a plane along which a carriage on which the tool assemblies are mounted is transported with the tools each positioned in the same attitude with respect to, and distance from, that path. The carriage is transported along the path to a position where one of the tools is adjacent the chuck which is rotated, if necessary, to position a desired point of interest on the sample immediately adjacent the tool. Once positioned, the tool engages the sample to perform a test. Following testing, the tool is disengaged from the sample and the process repeated as necessary for each additional test to be performed on the sample.Type: GrantFiled: July 16, 2002Date of Patent: November 2, 2004Assignee: Four Dimensions, Inc.Inventors: James T.

Patent number: 6800090Abstract: An assembly and method for effecting the condition of a mitral valve annulus of a heart includes a guide wire configured to be fed into the coronary sinus of the heart, and a mitral valve annulus therapy device configured to be slidingly received on the guide wire and advanced into the coronary sinus of the heart on the guide wire. A guide tube may further be employed for guiding the device into the coronary sinus. An introducer which may be employed for pushing the device into or pulling device out of the heart has a mechanism for releasably locking to the device. This enables substitution of the device if needed. Also, the crossover point of the circumflex artery and coronary sinus may be determined and avoided when the device is deployed.Type: GrantFiled: May 14, 2001Date of Patent: October 5, 2004Assignee: Cardiac Dimensions, Inc.Inventors: Clifton A.

Publication number: 20040153147Abstract: A mitral valve annulus reshaping device includes at least a portion that is formed of a biocompatible shape memory alloy SMA having a characteristic temperature, Af, that is preferably below body temperature. The device is constrained in an unstable martensite (UM) state while being introduced through a catheter that passes through the venous system and into the coronary sinus of the heart. The reshaping device is deployed adjacent to the mitral valve annulus of the heart as it is forced from the catheter. When released from the constraint of the catheter, the SMA of the device at least partially converts from the UM state to an austenitic state and attempts to change to a programmed shape that exerts a force on the adjacent tissue and modifies the shape of the annulus. The strain of the SMA can be varied when the device is within the coronary sinus.Type: ApplicationFiled: February 3, 2003Publication date: August 5, 2004Applicant: Cardiac Dimensions, Inc.Inventor: Mark L.

Publication number: 20040133240Abstract: A system for treating cardiac valve dysfunction includes a lead with electrodes in electrical communication with muscle tissue proximate to a cardiac valve to be treated. Electrical energy is delivered to the lead electrodes to stimulate contraction of the muscle tissue and thereby constrict the cardiac valve. The lead may be received within a blood vessel in the patient. Detection circuitry may detect a physiological signal in the patient for controlling the timing of delivery of electrical energy. The lead may have one or more undulations. The lead may also be combined with a prosthesis to provide a combined electromechanical cardiac valve therapy. The lead can be attached to the prosthesis or formed integrally with the prosthesis. One embodiment implanted in the coronary sinus is used to treat dilated cardiomyopathy of the mitral valve.Type: ApplicationFiled: January 7, 2003Publication date: July 8, 2004Applicant: Cardiac Dimensions, Inc.Inventors: John M.
