Intended Use

The MedicalCV, Inc. Atrilaze™ Soft Tissue Ablation System is indicated for delivery of 810nm laser light to soft tissue to include cardiac tissue during surgical procedures. Indications include the incision, dissection, vaporization, ablation, or coagulation of soft tissue.

Device Description

The Altrilaze Soft Tissue Ablation System consists of a generator designed for the delivery of 810nm laser light and a hand held fiber optic light delivery device (probe) fitted with a standard SMA 905 connector at the proximal rond. The system may be used in conjunction with surgical treatment for hemostasis, incision, ablation, coaeglytion and vaporization of tissue as required by the clinician.

AI/ML Overview

Here's a breakdown of the acceptance criteria and study information based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria (Inferred)Reported Device Performance
Biocompatibility:Non-toxic, non-hemolytic, non-pyrogenic
Materials used in the disposable probe must be biocompatible.
Manufacturing Specifications Compliance:Compliance to manufacturing specifications for:
- Power Output- Power Output
- Tip Pull-Off- Tip Pull-Off
- Pressure (for fiber optic delivery device)- Pressure
- Flow (for fiber optic delivery device)- Flow
Visual Evaluation of Lesions on Cardiac Tissue:Lesions obtained using the Atrilaze System on cardiac tissue were visually evaluated.
Substantial Equivalence:Demonstrated substantial equivalence to predicate devices (Biolitec/Ceramoptec Ceralas D10-25 and CardioFocus Diode Laser System) for the incision, dissection, vaporization, ablation or coagulation of soft tissue.

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

The provided text does not specify a sample size for a test set in the context of an algorithm or diagnostic device. This document describes a traditional medical device (a surgical laser system), and the testing performed is related to its physical and functional characteristics, not an AI or diagnostic algorithm applied to data.

Data Provenance: Not applicable in the context of an AI/diagnostic device. The testing involved biocompatibility testing and performance testing of the physical laser system.

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

This information is not applicable as the device is a surgical laser system, not an AI or diagnostic algorithm that relies on expert interpretation of "ground truth" for a test set. The visual evaluation of lesions on cardiac tissue would likely involve medical professionals (e.g., surgeons, pathologists), but the number and specific qualifications are not detailed.

4. Adjudication Method for the Test Set

This information is not applicable as the device is a surgical laser system, not an AI or diagnostic algorithm that requires adjudication of expert opinions for a test set.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is relevant for evaluating the performance of AI-assisted diagnostic tools where human readers interpret cases, and is not applicable to a surgical laser device described here.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

No, a standalone performance study as would be understood for an algorithm was not done. The device is a surgical laser system, and its performance is inherently tied to its use by a clinician.

7. The Type of Ground Truth Used

The "ground truth" in this context refers to the verifiable outcomes of the testing performed on the physical device. This includes:

  • Laboratory-established standards for biocompatibility: Demonstrating non-toxicity, non-hemolysis, and non-pyrogenicity.
  • Manufacturing specifications: Compliance with objective measurements of power output, tip pull-off strength, pressure, and flow.
  • Visual evaluation of tissue effects: Observation of lesions on cardiac tissue, likely compared against expected outcomes for surgical lasers.
  • Predicate device performance: The ability to perform equivalently to established predicate devices for soft tissue incision, dissection, vaporization, ablation, and coagulation.

8. The Sample Size for the Training Set

This information is not applicable. The device is a surgical laser system, not an AI or machine learning algorithm that requires a "training set."

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

This information is not applicable as there is no "training set" for this type of medical device.

Summary of Safety and Effectiveness (as required by 21 CFR 807.92)

Atrilaze™ Soft Tissue Ablation System

Date of Summary:November 18, 2004Classification Name:Laser Instrument,Surgical Powered
Common Name:Surgical Laser InstrumentProprietaryAtrilaze™ Soft TissueAblation System

Description of Device: The Altrilaze Soft Tissue Ablation System consists of a generator designed for the delivery of 810nm laser light and a hand held fiber optic light delivery device (probe) fitted with a standard SMA 905 connector at the proximal rond. The system may be used in conjunction with surgical treatment for hemostasis, incision, ablation, coaeglytion and vaporization of tissue as required by the clinician.

The MedicalCV Atrilaze Soft Tissue Ablation System is Statement of Intended Use: indicated for the delivery of 810nm laser light to soft tissue to include cardian tissue, driving surgical procedures. Indications include the incision, excision, dissection, vaportization, ablation or coagulation of soft tissue.

The Atrilaze Ablation System is not indicated for the treatment of cardiac Warning: arrhythmias.

The risk of actual damage to adjacent organs from the instrument exists and perforation, rupture or tearing of tissue, may occur as a complication of laser use. Burns can occur if the laser energy is not correctly applied. These complications may be serious.

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

Technological Comparison: The Atrilaze Soft Tissue Ablation System is a self contained compact surgical laser that utilizes gallium aluminum arsenide (GaAAs) semiconductor diodes to generate near-infrared laser radiation. A fiber optic delivery system (probe) is coupled to the laser via an SMA 905 connector to deliver laser radiation to the target tissue(s). For purposes of this submission, the Atrilaze Soft Tissue Ablation System was compared to the following predicate device(s):

  • Biolitec/Ceramoptec Ceralas D10-25 Fiber-coupled Diode Laser System (K001975) .
  • CardioFocus Diode Laser System (K013201) .

The results of biocompatibility testing support that the materials used in the Testing: manufacture of the Altrilaze Soft Tissue Ablation disposable probe are non-toxic, non-hemolytic, and non-pyrogenic. All biocompatibility testing was conducted under Good Laboratory Practices per 21 CFR Part 58. Performance testing for the Atrilaze Soft Tissue Aboation System y rluded compliance to manufacturing specifications for Power Output, Tip Pull-Off, Pressure and Flow for the fiber optic delivery device, also visual evaluation of the lesions obtained using the Altrilaze Soft Tissue Ablation System on cardiac tissue was performed. Testing demonstrated that the Altrilaze Soft Tissue Ablation System is substantially equivalent to the predicated and ablation of soft tissue.
