Intended Use

The Enpath Deflectable Catheter is intended to be used to facilitate the placement of interventional devices into the peripheral and coronary systems.

Device Description

The Enpath Deflectable Catheter is a guide catheter (delivery sheath) which has a distal tip that deflects to create a variable curve shape. The deflection is controlled through a handle mechanism with the ability to lock at any point along the catheter tip curve travel. The handle incorporates a luer fitting or a hemostasis valve. The deflectable catheter shaft is constructed of Pebax, lined with PTFE and filled with Barium Sulfate as a radiopacifier. The catheter hub is overmolded Nylon 12 (10% glass filled). The catheter hub houses a hemostasis valve which is molded silicone rubber. The deflectable catheter handle is made of machined ABS, and is cyanoacrylate bonded onto the deflectable shaft. The dilator tube is made of MDPE (high density/low density polyethylene blend) and has a hub made of HDPE resin overmolded onto the dilator tube. The dilator assembly is coated with silicone lubricant to reduce insertion force through the sheath hemostasis valve. The deflectable tip sheath size range is from 7 FR (ID) to 14 FR. The materials and construction are the same for all French sizes. The Deflectable Tip Sheath will be packaged and EtO sterilized for single use in a Tyvek pouch. The sterile kit packaging configuration will include the deflectable catheter and the dilator. The product may be provided as a bulk non-sterile device to OEM customers for further processing and packaging.

AI/ML Overview

Here's a breakdown of the acceptance criteria and study information for the Enpath Deflectable Catheter, based on the provided 510(k) summary:

1. Acceptance Criteria and Reported Device Performance

The submission statement indicated that the device performs per specification requirements, however specifics criteria and performance metrics were not provided.

Acceptance CriteriaReported Device Performance
Device SpecificationsPerforms per requirements (details not provided)
Functional Testing of ArticulationPerforms per requirements (details not provided)
Deflection RadiusPerforms per requirements (details not provided)
Deflection ForcePerforms per requirements (details not provided)
Hemostasis of the Valve PortionPerforms per requirements (details not provided)
Deflection Cycle TestingPerforms per requirements (details not provided)
Consistent with FDA Guidance (3/19/1995) for Intravascular Catheters (as applicable)Performs per requirements (details not provided)

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the sample size for the test set or the data provenance (country of origin, retrospective/prospective). It refers generally to "performance testing" and "test results" without specific numbers of devices tested.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

This information is not provided. The ground truth for the performance testing appears to be based on engineering specifications and in-house testing rather than expert clinical assessment.

4. Adjudication Method for the Test Set

This information is not provided. It's likely that the testing involved objective measurements against established specifications rather than a consensus-based adjudication process typical for clinical or image-based studies.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No. An MRMC comparative effectiveness study was not conducted or reported. This type of study typically involves human readers analyzing cases with and without AI assistance, and it's not applicable to a device like a catheter where the primary assessment is mechanical and functional performance.

6. Standalone (i.e., algorithm-only without human-in-the-loop performance) Study

Yes, in essence, the described "performance testing" is a standalone evaluation of the device's mechanical and functional properties without human intervention during the measurement process. The "algorithm" in this context refers to the device's design and manufacturing, and its performance was assessed independently of a human operator's influence on the test outcome (beyond initiating the test).

7. Type of Ground Truth Used

The ground truth used for the device's performance testing was based on engineering specifications and established functional requirements derived from the device's intended use and relevant FDA guidance.

8. Sample Size for the Training Set

This information is not applicable and is not provided. The Enpath Deflectable Catheter is a physical medical device, not an AI/software algorithm that requires a "training set" in the machine learning sense. The development and verification of such devices rely on engineering design, material science, and physical testing.

9. How the Ground Truth for the Training Set Was Established

This information is not applicable. As stated above, this is a physical device, not an AI/software algorithm, so there is no "training set" or "ground truth for the training set" in the context of machine learning. The design and manufacturing process would involve engineering principles, material selection, and iterative prototyping and testing to meet performance objectives.

Device Description

The Enpath Deflectable Catheter is a guide catheter (delivery sheath) which has a distal tip that deflects to create a variable curve shape. The deflection is controlled through a handle mechanism with the ability to lock at any point along the catheter tip curve travel. The handle incorporates a luer fitting or a hemostasis valve. The product specifications, drawings and photographs are located in Appendix E of this submission.

The Enpath Deflectable Catheter will be used clinically in the same way that a guide catheter or sheath is used as part of an interventional procedure, to gain access to locations that are not easily

{1}------------------------------------------------

accessed with existing tools. Certain parts of the vasculature are difficult to access because of occlusion, tortuosity, or simply because standard catheters do not provide the necessary curve angle(s). The Deflectable Catheter, with its deflection capability, enables access to these areas. Primary applications for product focus on access for Pulmonary Vein Ablation, Transseptal access, Renal Stenting, and Carotid Stenting.

The deflectable catheter shaft is constructed of Pebax, lined with PTFE and filled with Barium Sulfate as a radiopacifier. The catheter hub is overmolded Nylon 12 (10% glass filled). The catheter hub houses a hemostasis valve which is molded silicone rubber.

The deflectable catheter handle is made of machined ABS, and is cyanoacrylate bonded onto the deflectable shaft. The handle configuration may vary based on specific user requirements. The handle modifications will not effect the functionality or safety of the device. For example, the shape of the handle, method of deflection (i.e. slide, rotate etc) may change, but the curve of the deflection and the shaft of the device will remain the same. Any handle changes will be validated and appropriately tested to ensure safety and effectiveness.

The dilator tube is made of MDPE (high density/low density polyethylene blend) and has a hub made of HDPE resin overmolded onto the dilator tube. The dilator assembly is coated with silicone lubricant to reduce insertion force through the sheath hemostasis valve.

The deflectable tip sheath size range is from 7 FR (ID) to 14 FR. The materials and construction are the same for all French sizes.

The Deflectable Tip Sheath will be packaged and EtO sterilized for single use in a Tyvek pouch. The sterile kit packaging configuration will include the deflectable catheter and the dilator. The product may be provided as a bulk non-sterile device to OEM customers for further processing and packaging.
