The catheter has a braided outer tube that exhibits similar torsional stiffness, under a clockwise and counterclockwise-applied torque directions, to those of the named predicate devices. The distal portion of the subject catheter has up to 20 platinum electrodes that offer radiopacity under fluoroscopy for the required visibility during the cardiac electrophysiology mapping procedures. The accessory cables used to connect the subject device to a recorder/monitor comply with Section 12A of the Underwriters Laboratories UL 544 Standard for safety. A schematic view of the Gyro-Tip Lariat Deflectable Loop Mapping Catheter is shown in Figure 1. #### [6] Indication for Use: Gyro-Tip lariat Deflectable Loop Mapping Catheter is indicated for multi electrode electrophysiological mapping, recording and/or temporary stimulation, of cardiac structures along circumferential paths. {2}------------------------------------------------ Cardiac Assist Devices, Inc. 11000 Cedar Avenue, Suite 451 Cleveland, Ohio 44106 (216) 791-2234 Phone: (216) 791-2234 Fax: Kol2520 R315 # 510(k) Summary Image /page/2/Figure/4 description: This image shows a catheter handle with a multi-pole end connector.

The subject device has more platinum electrodes (up to 20 electrodes) at its distal portion compared to the primary predicate device that has 4 electrodes. This total number of electrodes is however the same as the number of electrodes of the secondary predicate devices that are cleared for marketing under K953768 (Cordis Webster A20 Diagnostic Deflectable Tip Catheter) and K953663 (Cordis Webster T20 Diagnostic Deflectable Tip Catheter). Each of these secondary predicate devices has 20 electrodes at its distal portion. The distal portion of the subject device has a pre-formed bend at its distal portion. This pre-formed bend causes formation of a deflectable loop at the catheter's distal portion in response to the actuation of the steering mechanism located in the catheter handle of the subject device. The steering mechanism of the subject device is exactly similar to the steering mechanism of the primary predicate device, namely the Gyro Tip EP Catheter of Cardiac Assist Devices, Inc. The actuating wires that transmit the actuation forces from the steering mechanism of the catheter handle to the distal portion of the subject device are stainless steel wires having generally circular crosssection with a diameter in the order of 0.012". These actuating wires are the same as the actuating wires of the primary predicated device (cleared under K955847). The distal portion of the actuating wires of the subject device has rectangular crosssection, having the same effective cross-sectional area as that of the circular crosssection portion. This better determines the plane of loop formation at the distal portion of the subject device. The geometric plane, in which the distal loop of the subject device is formed, upon the manual actuation of the steering mechanism, is generally perpendicular to the elongated shaft of the catheter. Therefore the subject device can assume a "halo-shaped" configuration at its distal portion, similar to the "halo-shaped" configuration of the distal portion of the secondary predicate device, namely Cordis Webster T20 Diagnostic Deflectable Tip Catheter that is cleared under K953663. A {4}------------------------------------------------ Cleveland, Ohio 44106 Phone: (216) 791-2234 Fax: ## 510(k) Summary (continue) #### 171 Technological Characteristics of the Subiect Device (continued): The halo-shaped configuration of the distal portion of the subject device, and the process of assuming this final halo-shaped configuration, in response to the manual actuation of its steering mechanism, has shown to be safe and effective through a series of non-clinical testing. The descriptions and results of these tests are included in Appendices A , B, and C of this 510K, with a brief discussion presented next. #### [8] Brief Discussion of the Non-Clinical Tests: The subject device, (The Gyro-Tip Lariat Deflectable Loop Mapping Catheter) has gone under a series of non-clinical testing in order to determine its performance characteristics as they relate to its safety and effectiveness. These tests were performed according to FDA's "Electrode Recoding Catheter preliminary Guidance". The results of these non-clinical tests were compared to results of the same tests on predicate devices. The comparison of the results indicates that the subject device is as safe, and as effective, as the named predicate devices. #### 191 Conclusion Drawn From Non-Clinical and Clinical Tests: The results of the non-clinical tests. presented in Appendices A. B. C. D, and E of this 510(k) indicates that the subject device (The Gyro-Tip Lariat Deflectable Loop Mapping Catheter) performs as well as the named predicate devices, and any minute differences in the test results are not significant to influence the safety and effectiveness of the subject device. Therefore, Cardiac Assist Devices, Inc. presents the Gvro-Tip Lariat Deflectable Loop Mapping Catheter વડ substantially equivalent to the named predicate devices in this 510(k). 5 #### [10] Additional Information: Available upon request {5}------------------------------------------------ #### DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/5/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
