Intended 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.
Device Story
Talon Transseptal Sheath is a single-lumen catheter providing a conduit for cardiovascular catheterization and angiography. It features a proximal hemostasis valve, stopcock with flush port, and a radiopaque distal marker for fluoroscopic visualization. Packaged with a dilator (compatible with 0.035" guidewires), Y-connector, and syringes (quick-release and VacLok). Used by physicians in clinical settings to facilitate access to heart chambers. The device is inserted percutaneously; the dilator aids in positioning. Output is a stable conduit for secondary devices. Benefits include enabling minimally invasive access to the left atrium and other heart chambers for diagnostic or therapeutic procedures.
Clinical Evidence
No clinical data. Substantial equivalence supported by bench testing, including biocompatibility (ISO 10993-1), packaging integrity, dimensional inspections, compatibility testing (guidewire, dilator, Triever20, pigtail), torque, tensile, kink radius, leak, vacuum, flowrate, and radiopacity testing.
Technological Characteristics
Single-lumen catheter; Pebax 3533-7233 shaft material; 23 Fr OD, 20.7 Fr ID, 80 cm length; 90° in-plane and 30° perpendicular tip curve. Sterilized via EtO (SAL 10^-6) per ISO 11135:2014/Amd 1:2018 and AAMI TIR 28:2016. Mechanical device; no software or electronic components.
Indications for Use
Indicated for patients requiring percutaneous introduction of cardiovascular catheters and guidewires into heart chambers, including the left atrium via transseptal access.

Dear Ellen Nguyen:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). 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).

| Description | The Talon Transseptal Sheath (“Sheath”) provides a conduit for catheterization and angiography of specific heart chambers and locations. 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 |

{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.
