You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. {1}------------------------------------------------ Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

It consists of a single lumen catheter with a proximal hemostasis valve and stopcock with flush port. A radiopaque marker is positioned near the distal tip to aid with fluoroscopic visualization. The Sheath is packaged with a dilator and two 60 cc syringes. The dilator is compatible with a 0.035" guidewire and has a tapered tip which aids insertion and positioning of the Sheath. The dilator attaches to the Sheath hemostasis valve, and a Y-connector with hemostasis valve connects to the dilator luer connector. A quick-release syringe is provided to connect to the Sheath sideport, and a standard VacLok syringe is provided to connect to the Sheath flush port and dilator connector. | Shaft<br>Materials | Pebax 3533-7233 | Unknown | | Indications for Use | The Talon Transseptal Sheath is used for the percutaneous introduction of various types of cardiovascular catheters and guidewires to all heart chambers, including the left atrium via transseptal perforation/puncture. | Tip curve | 90° in plane, 30° perpendicular | 45°, 55°, 90° in plane | | Accessories<br>provided | Dilator, quick-release syringe,<br>standard VacLok syringe, Y-connector | Dilator, J-tipped guidewire | | | {4}------------------------------------------------ Summary of substantial equivalence A tabular comparison of the predicate and subject devices is provided below: Summary of substantial equivalence #### Biocompatibility ● The following biocompatibility tests were completed for the subject device: - . Cytotoxicity - Sensitization - Intracutaneous Reactivity Acute Systemic Toxicity . - Material-Mediated Pyrogenicity ● - . Hemocompatibility (Hemolysis, Complement Activation, Thromboresistance, Platelet and Leukocyte Count, and Partial Thromboplastin Time) {5}------------------------------------------------ The passing results demonstrate that the subject device and accessories meet biological safety requirements per ISO 10993-1. #### Sterilization The subject device, including its accessories, is sterilized using EtO to achieve a sterility assurance level (SAL) of 106 using a validated sterilization process in accordance with the principles of ISO 11135:2014/Amd 1:2018 and AAMI TIR 28:2016. #### Non-Clinical Testing In accordance with the Design Failure Modes and Effects Analysis, verification and validation testing were identified to support the substantial equivalence of the Talon Transseptal Sheath to the predicate device. These tests included: #### Performance Tests - Packaging Integrity ● - Visual and Dimensional Inspections ● - Guidewire and Sheath Compatibility ● - Dilator Compatibility - Test Small-Bore Connectors for Intravascular Applications - Insertion and Removal Force of Dilator - Simulated Use, Track and Transseptal Access ● - Simulated Use, Track and Triever20 Curve Compatibility - Shape Recovery Angles - Simulated Use, Track and Pigtail Compatibility - Torque Testing ● - Simulated Use, Track and Kink Radius ● - Simulated Use, Track and Torque Testing Talon ● - Simulated Use, Track and Torque Testing Talon and Triever20 ● Curve - Leak Testing Sheath and Dilator ● - Vacuum Testing . - Air Leakage During Aspiration - Tensile Testing - Particulate Evaluation - Snare Compatibility ● - Shaft Stiffness Testing ● - Tip Stiffness Testing ● - Force Transmission ● - Flowrate through Sheath - Torque to Failure ● - Radiopacity ● Test results demonstrated that all acceptance criteria were met; therefore, the device conforms to established product specifications. {6}------------------------------------------------ Animal testing was not required for the determination of substantial equivalence. Clinical testing was not required for the determination of substantial equivalence. #### Conclusion The Talon Transseptal Sheath has the same intended use/indications for use and principles of operation as the predicate. Non-clinical performance data show that the different technological characteristics between the devices do not raise any new or different questions of safety or effectiveness and support the Talon Transseptal Sheath's substantial equivalence to the predicate device.
