Intended Use

The Talon Surgical 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.

Device Story

CardioCurve Steerable Sheath is a sterile, single-use catheter introducer (8.5F) for guidewire/catheter exchange and cardiovascular device delivery. Device comprises a polymer shaft (barium-loaded Pebax/Nylon) with stainless-steel braid reinforcement, radiopaque tip marker, and ABS handle. Handle features two linked rotating dials for 180° bi-directional tip deflection. Includes side port with three-way stopcock for aspiration/infusion/pressure monitoring and integrated Tuohy Borst adaptor. Used in clinical settings by physicians to facilitate access to heart chambers. Device provides mechanical conduit for interventional tools; physician manually manipulates handle to steer distal tip under fluoroscopic guidance. Benefits include improved access to cardiac surfaces and procedural flexibility via bi-directional steering and variable lengths.

Clinical Evidence

Bench testing only. Testing included visual inspection, dimensional verification, guidewire/dilator compatibility, deflection/retention, shaft tip buckle, leakage (ISO 11070), hub/stopcock compliance (ISO 80369-7, ISO 594), tensile strength, and packaging/aging (ASTM D4169, ISO 11607-1, ASTM F1980). Biocompatibility testing per ISO 10993-1 included cytotoxicity, sensitization, irritation, systemic toxicity, and hemocompatibility (PTT, hemolysis, complement activation). A thrombogenicity study was conducted in an ovine model. All tests met requirements.

Technological Characteristics

8.5F catheter introducer; lengths 40-82cm. Materials: Barium-loaded Pebax/Nylon shaft, stainless-steel braid, ABS handle, HDPE dilator. Bi-directional 180° deflection via mechanical pull-wires. Radiopaque tip marker. Connectivity: None. Sterilization: Ethylene Oxide. Standards: ISO 11070 (leakage/tensile), ISO 80369-7 (hub), ISO 594 (stopcock), ASTM D4169/ISO 11607-1 (packaging), ISO 10993 (biocompatibility).

Indications for Use

Indicated for patients requiring introduction of cardiovascular devices to epicardial or endocardial heart surfaces, including transseptal access to the left heart.

Dear Jay Muse:

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.

#### DEVICE DESCRIPTION:

The Talon Surgical CardioCurve Steerable Sheath is a 8.5F sterile, single-use, catheter introducer used for the introduction, withdrawal, and exchange of guidewires and catheters while minimizing blood loss. It is available in lengths of 40, 61, 71 or 82 cm. The introducer is packaged with a custom dilator and a 180 cm, 0.032", super stiff, market cleared guidewire (K935170). A side port with three-way stopcock allows blood aspiration, fluid infusion, and pressure monitoring. An integrated Tuohy Borst adaptor is designed to hold a guidewire or catheter in place. The steerable sheath features distal side holes to facilitate aspiration and minimize cavitation, and a stainless-steel ring for visualization under fluoroscopy.

The handle is equipped with two linked rotating dials used to deflect the tip clockwise and counterclockwise 180°. The descriptions of the model numbers are listed below.

The CardioCurve Steerable Sheath shaft is made from barium loaded Pebax and Nylon and 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 Steerable Sheath Dilator can be used with a curved transseptal St. Jude Medical BRKTM type needle with stylet if indicated on the package label.

The CardioCurve Steerable Sheaths are substantially equivalent to the predicate device, Agilis NxT Steerable Introducer (K110450) and the reference devices, Agilis PF Delivery System (K111943) and Agilis NxT Introducer (K081645). The CardioCurve

{10}------------------------------------------------

Steerable Sheath and the Agilis Introducers provide access to the heart for the use of cardiovascular devices. The additional length, ability to deflect 180° in both directions, the ability to deflect from two locations on the handle and the addition of the Tuohy Borst to hold guidewires or catheters in place provide additional flexibility for the physician and do not raise new questions of safety and effectiveness from the predicate.
