This device can be used to embed most known brands and styles of PD catheters when the nephrologist determines this action is in the best interest of the patient, however, only immediately after successful catheter implantation.

The Embedding™ Tool is indicated for embedding the external portion of most PD catheters subcutaneously in anticipation of future retrieval of that part of the catheter, provided that:

• The embedding procedure is done immediately following PD . catheter implantation.
• Catheter patency has been completely established. .
• The normally external part of the PD catheter can be embedded. .
• The patient is a candidate for delayed onset of PD treatment. .
• The patient is a candidate for PD. .

The Embedding™ Tool consists of a gently curved handle portion made of rigid PVC with a detachable titanium tip and a separate titanium cap.

The Medigroup, Inc. Embedding™ Tool (TE-1000) is a device used to temporarily embed the external portion of a peritoneal dialysis catheter subcutaneously following initial implantation, for later retrieval and initiation of peritoneal dialysis.

Here's an analysis of the provided information regarding its acceptance criteria and supporting study:

1. Table of Acceptance Criteria and Reported Device Performance

Note: The provided document does not explicitly state quantitative acceptance criteria or specific performance metrics (e.g., minimum tensile strength, specific success rate percentage). The statements are qualitative.

2. Sample Size and Data Provenance

• Test Set Sample Size: Not explicitly stated. The document mentions "Clinical evaluation at a dialysis center," implying human subject participation, but no numbers are provided for this evaluation.
• Data Provenance: Not explicitly stated. The "clinical evaluation at a dialysis center" suggests prospective clinical use, but the specific country of origin is not mentioned.

3. Number of Experts and Qualifications for Ground Truth

• Number of Experts: Not stated.
• Qualifications of Experts: The clinical evaluation was conducted at a "dialysis center," implying involvement of medical professionals familiar with peritoneal dialysis and catheter procedures. The intended users are "physicians familiar with proper catheter tunneling techniques" and "nephrologist." These suggest that the experts involved would likely be nephrologists or surgeons experienced in implanting and managing PD catheters. Specific years of experience or board certifications are not provided.

4. Adjudication Method for the Test Set

• The document does not describe any specific adjudication method (e.g., 2+1, 3+1). The "clinical evaluation" seems to be a direct assessment of the device's function by the users/medical staff at the dialysis center.

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

• No MRMC comparative effectiveness study was done. The device's function is mechanical and procedural, not diagnostic or interpretive by multiple readers. Therefore, an MRMC study comparing human readers with and without AI assistance is not applicable.

6. Standalone Performance Study (Algorithm Only)

• This is not an AI-powered device, and therefore, no standalone algorithm-only performance study was conducted. The device is a physical tool.

7. Type of Ground Truth Used

• For "Functional testing": The ground truth would have been established through engineering specifications, material properties, and mechanical test standards (e.g., assessing strength, durability, fit, and operation as designed).
• For "Clinical evaluation": The ground truth was the direct observation of the device functioning "as intended" during actual clinical use in patients undergoing peritoneal dialysis catheter implantation. This would likely involve physician assessment of successful embedding, ease of use, and absence of immediate complications related to the device.

8. Sample Size for the Training Set

• There is no training set mentioned, as this is a physical medical device, not an AI/machine learning algorithm. Therefore, "sample size for the training set" is not applicable.

9. How Ground Truth for the Training Set Was Established

• Not applicable, as there is no training set.
