Publication number: 20070261235Abstract: A tool is used for the removal of a processor from a heat sink for replacement or repair, or for delivery of the processor for servicing. The tool combines the features for the removal of the processor from the heat sink and a covered container for storage and delivery of the processor. The tool has at least one recess therein sized to correspond to the shape of the processor. The recess is sufficiently deep to receive the entire processor without damage to any contact pins that may be on the processor surface. The tool has sufficient rigidity to permit the tool and processor to be rotated relative to the heat sink to which the processor is adhered.

Publication number: 20050228290Abstract: Steerable catheters are provided including an elongated flexible member having a proximal end, a distal end and a lumen extending therebetween (i.e., between the proximal end and the distal end). A plurality of electrical cables is bundled together and positioned within the lumen of the flexible member. The cross-section of the bundle of electrical cables is substantially ovular or rectangular so as to be bendable in two approximately opposite directions. Methods of steering such a catheter within a body include advancing the catheter within a body while a first force is applied to the bundle of electrical cables to cause the distal end of the elongate flexible member to form a bend. The catheter is farther advanced within the body while a second, opposite force is applied to the bundle of electrical cables to remove the bend in the distal end.Type: ApplicationFiled: April 7, 2004Publication date: October 13, 2005Applicant: EP MedSystems, Inc.Inventors: Simcha Borovsky, Praveen Dala-Krishna, Charles Byrd

Publication number: 20050131474Abstract: A method and system for initializing a pacemaker includes receiving electrophysiology (EP) data from an intra-body EP catheter or catheters positioned relative to a patient's heart, calculating a patient specific pacemaker operating parameter or parameters from the received EP data and programming the pacemaker to operate based on the calculated patient specific pacemaker operating parameter or parameters. Stimulation of the patient's heart using the EP catheter or catheters based on the calculated pacemaker operating parameter or parameters may then be accomplished to determine whether the patient's heart achieves an acceptable physiological response when stimulated based on the calculated pacemaker operating parameter or parameters, and recalculation of the pacemaker operating parameter or parameters may be accomplished if the stimulation fails to achieve the acceptable physiological response.Type: ApplicationFiled: December 3, 2004Publication date: June 16, 2005Applicant: EP MedSystems, Inc.Inventors: David Jenkins, Charles Byrd
