Device Story

Sterile, single-use percutaneous catheter introducer; consists of steerable sheath and dilator. Handle features deflection mechanism with integrated wire for unidirectional shaft deflection; facilitates positioning of catheters advanced through sheath into heart chambers. Includes hemostasis valve to minimize blood loss during catheter/wire exchange; side port with stopcock for infusion, flushing, aspiration, and pressure monitoring. Used by clinicians in cardiovascular procedures. Provides maneuverability for catheters; enables access to heart chambers. Modifications include minor dimensional changes to hemostasis valve assembly, modified molding process temperature for valve seal, and addition of silicone oil to dilator shaft.

Clinical Evidence

Bench testing only. Testing included leak/air ingress performance, hemostasis valve performance, insertion/removal cycling, dilator insertion/removal force, bond pull force, and compatibility verification. All results met design specifications.

Technological Characteristics

Steerable catheter introducer; unidirectional deflection. Materials: Pebax, stainless steel braid, PTFE liner, polycarbonate, polypropylene, Hytrel, silicone oil. Dimensions: 13F OD, 10F ID, 81cm total length. Sterilization: Ethylene Oxide (EtO).

Indications for Use

Indicated for percutaneous catheter introduction into the vasculature and into the chambers of the heart, including the left side of the heart through the interatrial septum. Sheath deflection facilitates catheter positioning.

The sheath deflection facilitates catheter positioning. <p>The indications for use are the same as previously cleared for the original FlexCath Select Steerable Sheath and Dilator, predicate device (K142684). </p> |
| Comparison of<br>Technological<br>Characteristics : | The FlexCath Select Steerable Sheath and Dilator has the following similarities to the predicate device: <ul><li>Same intended use</li><li>Same indications for use</li><li>Same fundamental scientific technology</li><li>Same unidirectional deflection</li><li>Same basic sheath and dilator design</li><li>Same user interface</li><li>Same materials of construction</li><li>Same sterilization process</li><li>Same packaging configuration</li><li>Same device shelf life</li></ul> <p>The differences between the modified FlexCath Select and the predicate device consist of the following: </p> <ul><li>Minor dimensional changes to hemostasis valve assembly components </li><li>Modified molding process temperature for the valve seal component </li><li>Added silicone oil to the entire length of the dilator component; this silicone oil was present on the predicate device hemostasis valve </li></ul> |

{5}------------------------------------------------

These changes do not constitute a change in the fundamental scientific technology for the proposed device; the differences between the modified FlexCath Select and the predicate do not raise new or different questions of safety and effectiveness. The FlexCath Select does not provide a new therapy, and the intended use and indications for use remain equivalent to that of the predicate. The modified FlexCath Select described in this Traditional 510(k) submission is substantially equivalent to the predicate device, reference Table 1.

Bench testing was completed to support the proposed Performance Data: modifications to the FlexCath Select. Performance testing verified that the subject device performs as designed and is suitable for the intended use.

Testing included:

- Leak/air ingress performance - Hemostasis valve
- Valve performance following insertion/removal cycling -. sheath/valve
- Dilator insertion/removal force
- Bond pull force sheath/hub ●
- . Compatibility verification

Design verification testing was performed to verify that the Conclusion: performance of the modified FlexCath Select remains substantially equivalent to the predicate device. All results demonstrate that the properties and performance of the modified FlexCath Select are suitable for the intended use. There are no differences between devices identified in testing that raised new questions of safety or effectiveness.
