The Amplatzer™ Steerable Delivery Sheath is indicated to facilitate the delivery of the Amplatzer™ Amulet™ Left Atral Appendage Occluder.
The Amplatzer Steerable Delivery Sheath is a sterile (EO), single use sheath designed to provide a pathway through which a device may be delivery sheath is available in one size, 14F. The sheath will be used to deliver an Amplatzer Amulet™ Left Atrial Appendage Occluder. The Amplatzer™ Steerable Delivery Sheath is comprised of three components: a sheath to deliver the device, a dilator to ease penetration of tissue, and a 2X to 1X Flush Adapter to facilitate connection of additional device components.
The sheath is comprised of the distal tip, sheath body and sheath handle. The distal tip design utilizes a dual fixed curve in two dimensions, resulting in a three-dimensional geometry. The sheath body is radiopague for visibility under fluoroscopy and includes a marker band located in the distal tip to aid with visualization during device deployment and recapture. The Steerable Sheath device has been designed with a bi-directional distal tip which is controlled by pull-wires along the sheath body connected to the device handle to provide better co-axial alignment between the appendage and sheath, allowing for more accurate device placement. Additionally, a hemostasis valve and side port are integrated in the device handle to support improved procedural hemostasis control and ease of use. The sheath has an effective length of 75 cm and 98.5 cm overall length. The sheath is compatible with a 0.35" guidewire and a 19F introducer.
This Special 510(k) is being submitted to add additional precautions and updated procedural steps to the Instructions for Use (IFU) of the Amplatzer Steerable Delivery Sheath.
This appears to be a 510(k) summary for the Amplatzer™ Steerable Delivery Sheath. Based on the provided text, the submission is a "Special 510(k)" to add additional precautions and updated procedural steps to the Instructions for Use (IFU).
Crucially, the document states: "There are no changes in technological characteristics from the predicate device." and "As there are no changes in the indication for use, intended use, technological characteristics, the Amplatzer Steerable Delivery Sheath is substantially equivalent to the primary predicate device (K212026)."
This means that the provided document does not contain the full details of the original acceptance criteria and the study that proved the device met those criteria, as it refers back to the predicate device (K212026) for the substantial equivalence. The current submission only addresses the safety and effectiveness of the updated IFU, primarily through a Human Factors evaluation.
Therefore, I cannot fully complete the requested table and answer all questions based solely on the provided text. I can only infer what kind of testing would have been done for the original clearance based on typical medical device regulations and what is mentioned about the current submission.
Here's what can be extracted and inferred from the provided text regarding this specific 510(k) submission:
Device: Amplatzer™ Steerable Delivery Sheath
Reason for this 510(k) Submission (K220340): To add additional precautions and updated procedural steps to the Instructions for Use (IFU).
Key Statement: "There are no changes in technological characteristics from the predicate device."
Acceptance Criteria and Device Performance (Based on this Special 510(k) submission)
Acceptance Criteria | Reported Device Performance |
---|---|
Updated IFU does not introduce new user-device interactions that compromise safety or effectiveness. | "It was concluded that use of the Amplatzer Steerable Delivery Sheath with the updated IFU remains safe and effective for the intended users, uses, and use environments." (Based on Human Factors evaluation) |
Study Information (Based on this Special 510(k) submission):
- Sample size used for the test set and the data provenance: Not explicitly stated, but the study type is a "Human Factors evaluation." These typically involve a relatively small number of representative users performing tasks with the device and new IFU. The provenance is likely within a controlled lab environment.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not explicitly stated. For a Human Factors study, "ground truth" relates to identifying usability issues and risks. Experts might include human factors specialists, clinicians, and engineers.
- Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not explicitly stated. For Human Factors, this would involve systematic observation and analysis of user performance, errors, and feedback.
- If a multi reader multi case (MRMC) comparative effectiveness study was done: No, not for this specific 510(k) submission. This is a Human Factors evaluation, not a clinical effectiveness trial for the device's diagnostic or therapeutic performance.
- If a standalone (i.e. algorithm only without human-in-the loop performance) was done: No, this is a physical medical device. The "standalone" concept applies more to AI/software.
- The type of ground truth used: For a Human Factors study, the "ground truth" is the observed user behavior, identified use errors, and subjective feedback compared against expected safe and effective use.
- The sample size for the training set: Not applicable, as this is a Human Factors study, not an AI/ML model.
- How the ground truth for the training set was established: Not applicable.
Information that would be in the original K212026 submission:
To fully answer your request regarding the original acceptance criteria and proof of device performance (e.g., mechanical, electrical, biocompatibility, and potentially clinical performance) for the Amplatzer™ Steerable Delivery Sheath, one would need to review the predicate device's 510(k) submission (K212026). That submission would contain:
- Detailed performance testing (e.g., tensile strength, steerability, torqueability, burst pressure, fatigue, material compatibility, dimensional stability, etc.) directly linked to the device's design specifications and intended use.
- Biocompatibility testing
- Sterilization validation
- Potentially, pre-clinical (in-vitro or in-vivo) or clinical studies if substantial changes were made from its own predicate, or if it was the first of its kind. Given it's a catheter delivery system, comparative bench testing and possibly animal studies would be typical.
Conclusion:
This specific 510(k) (K220340) demonstrates continued safety and effectiveness through a Human Factors evaluation of updated Instructions for Use. It relies on the substantial equivalence to its predicate (K212026) for the fundamental performance claims of the Amplatzer™ Steerable Delivery Sheath itself. Therefore, the detailed performance data and acceptance criteria for the device proper (not just its IFU) would be found in the K212026 submission.
