It is available in lengths of 40cm, 61cm, 71cm, or 82cm. The introducer is packaged with a custom dilator and a 180 cm, 0.032", super stiff, marketed cleared guidewire (K935170). A side port with a 3-way stopcock allows air or blood aspiration, fluid infusion, blood sampling, and pressure monitoring. A handle equipped with two linked rotating dials is used to deflect the tip clockwise and counterclockwise 180°. The steerable sheath features distal vent holes to facilitate aspiration and minimize cavitation, a radiopaque tip marker to improve fluoroscopic visualization, and a lubricious coating on the outer surface. The CardioCurve™ Steerable Sheath shaft is made from Pebax and Nylon. The shaft includes a radiopaque tip marker for visibility under fluoroscopy and is braided, except for the distal tip, for kink resistance; the handle is made of ABS. The dilator is made of HDPE that is barium loaded for visibility under fluoroscopy. The CardioCurve™ dilator can be used with a curved transseptal Abbott BRK™ type needle with stylet if indicated on the package label. This Special 510(k) is submitted to support the changes made to the predicate device: the Tuohy Borst adapter in the CardioCurve Steerable Sheath is replaced with a cap; as a result of this {5}------------------------------------------------ change, the dilator shaft usable length is shortened, and the Instruction for Use (IFU) is updated. Verification testing has been conducted to support that the subject device meets the design specifications and is substantially equivalent to the predicate device. ### Indication for Use 4 The CIRCA Scientific CardioCurve™ Steerable Sheath is indicated when introducing various cardiovascular devices to the epicardial or endocardial surfaces of the heart, including the left side of the heart through the interatrial septum. | Attribute | CardioCurve Steerable Sheath – Predicate (K210185) | CardioCurve Steerable Sheath – Subject Device | Discussion | |------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------| | Class | II | II | Identical | | Product Code | DYB | DYB | Identical | | Regulation (FDA) | 870.1340 | 870.1340 | Identical | | Intended Use | To provide access to the heart for use of cardiovascular devices. | To provide access to the heart for use of cardiovascular devices. | Identical | | Indications for Use | The Talon Surgical CardioCurveTM Steerable Sheath is indicated when introducing various cardiovascular devices to the epicardial or endocardial surfaces of the heart, including the left side of the heart through the interatrial septum. | The CIRCA Scientific CardioCurveTM Steerable Sheath is indicated when introducing various cardiovascular devices to the epicardial or endocardial surfaces of the heart, including the left side of the heart through the interatrial septum. | Identical (Company name, Talon Surgical, was replaced by CIRCA Scientific) | | Where Used | Endocardial and Epicardial indications | Endocardial and Epicardial indications | Identical | ### Comparison of Technological Characteristics with the Predicate Device 5 {6}------------------------------------------------ | Attribute | CardioCurve Steerable Sheath - Predicate (K210185) | CardioCurve Steerable Sheath - Subject Device | Discussion | |--------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Principles of Operation | Access is obtained, the 0.032" guidewire is inserted and positioned.

Design verification tests were performed to demonstrate that the subject device, CIRCA Scientific CardioCurve Steerable Sheath, met predetermined performance specifications and to ensure that there were no significantly modified risks associated with the changes to the predicate design. Testing performed demonstrated that the subject device met critical design specifications as well as performance attributes for its intended use. The methods and acceptance criteria were the same or equivalent to the predicate device and are relevant to the changes under review. The testing identified in the list below was based on well-established test methods and requirements. - Packaging Inspection 0 - o Sheath Surface Visual Inspection - Dilator Effective Length ● - Dilator Extension from Sheath 0 - Sheath Deflection Fatigue and Wear ● - Sheath Liner, Deflection Portion, and Coating Integrity - o Sideport Tube Infusion / Aspiration - Sheath Fluid Leak Test Hemostasis valve ● - Sheath Fluid Leak Test – Fluid Path - Air Aspiration Leak Test - Sideport Tube to Shaft Housing Connection - o Dilator Hub to Cap Connection Strength - Sheath Shaft to Handle/Hub Strength . ## 7 Conclusions The subject device has the same intended use, indication for use, and principles of operation as the predicate device. Results from verification testing demonstrated that the different technological characteristics did not raise different questions of safety and effectiveness. Therefore, the subject device, CIRCA Scientific CardioCurve™ Steerable Sheath, is considered substantially equivalent to the predicate, CardioCurve™ Steerable Sheath (K210185).
