The RMST Staple is intended for fixation of prosthetic material to soft tissues in various minimally invasive and open surgical procedures, such as the management and protection of tendon injuries in which there has been no substantial loss of tendon tissue.
RMST Staple is an absorbable polymer strap with cleat tips. RMST Staple is composed of absorbable synthetic polyester derived from lactic acid and dyed with D&C Violet #2. The RMST Staple is used in conjunction with an orthopedic manual staple driver from Rotation Medical.
The Rotation Medical Soft Tissue Staple (RMST Staple) was evaluated through a series of in vitro and in vivo tests to establish its safety and substantial equivalence to a predicate device.
1. Table of Acceptance Criteria and Reported Device Performance:
| Test Category | Acceptance Criteria/Description | Reported Device Performance |
|---|---|---|
| Biocompatibility | Compliance with FDA Blue Book Memorandum G95-1 and ISO 10993-1 for biological evaluation. | The device passed all applicable FDA Blue Book Memorandum G95-1 and ISO 10993-1 testing. Specific tests performed included: - Cytotoxicity - Sensitization - Intercutaneous reactivity - Acute systemic toxicity - Pyrogenicity - Muscle implantation - Subchronic toxicity - Hemolysis |
| Product Characterization & Bench Testing | Evaluation of general physical properties, including tensile strength and retention strength (pull-out), to demonstrate substantial equivalence to the predicate device. | The RMST Staple underwent in vitro product characterization studies and bench testing. These included assessments of: - Tensile strength - Retention strength (pull-out) - General physical properties (e.g., size, surface area, weight, and strength retention) The results demonstrated that the RMST Staple is substantially equivalent to the predicate device, Ethicon SecurestrapTM 5mm Absorbable Strap Fixation Device (K093845). |
| Animal Efficacy Study | Not explicitly stated as acceptance criteria, but performed to demonstrate safety and equivalence. | An animal efficacy study was performed. The results from this study, along with the in vitro and in vivo biocompatibility studies and bench testing, demonstrate that the RMST Staple is safe and substantially equivalent to the predicate devices. |
2. Sample size used for the test set and the data provenance:
- The document does not explicitly state specific sample sizes for each individual test (e.g., cytotoxicity, tensile strength). The phrasing "a number of in vitro and in vivo tests" suggests a sufficient number were conducted to meet regulatory requirements.
- The data provenance is not explicitly stated in terms of country of origin.
- The studies were likely prospective in nature, as they were conducted specifically for the purpose of demonstrating safety and efficacy for regulatory submission.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This information is not provided in the document. The studies described are primarily laboratory and animal-based, not involving human expert interpretation for "ground truth" in the way a diagnostic AI might.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- Not applicable. The studies described are pre-clinical (in vitro, in vivo animal) and bench testing, not reliant on human adjudication of a specific output like in a clinical diagnostic study.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- No, an MRMC comparative effectiveness study was not done. This device is a surgical staple, not a diagnostic imaging device or an AI-assisted diagnostic tool.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable. The device is a physical surgical staple, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- For the biocompatibility studies, the "ground truth" would be established by standard scientific and regulatory methods for assessing biological response (e.g., cellular observation for cytotoxicity, macroscopic/microscopic tissue evaluation for implantation studies).
- For the product characterization and bench testing, the "ground truth" would be objective measurements and engineering standards (e.g., force required for tensile strength, displacement for pull-out).
- For the animal efficacy study, the "ground truth" would be pre-defined clinical and histological endpoints observed in the animal models.
8. The sample size for the training set:
- Not applicable. This device is a physical product, not an AI model requiring a training set.
9. How the ground truth for the training set was established:
- Not applicable, as no training set for an AI model was involved.

Intended Use
The RMST Staple is intended for fixation of prosthetic material to soft tissues in various minimally rne Kins 1 Stapie is international such as the management and protection of tendon injuries in which there has been no substantial loss of tendon tissue.
Summary/Comparison of Technical Characteristics
RMST Staple and the predicate device have similar indications for use, technological characteristics, and material composition. Both devices are comprised of a polymer strap with barbed ends which engage in soft tissue. RMST Staple and the currently marketed Ethicon Securestrap (predicate device) are both indicated for the fixation of prosthetic material to soft tissues in various minimally invasive and open surgical procedures. Both devices are composed of similar absorbable synthetic polyester and contain the same D&C Violet #2 dye.
RMST Staple has been evaluated in a number of in vitro and in vivo tests to assess its safety/biocompatibility, including: tensile strength, retention strength (pull-out), cytotoxicity, sensitization, intercutaneous reactivity, acute systemix toxicity, pyrogenicity, muscle implantation, subchronic toxicity, and hemolysis. RMST Staple and its predicate have been implantedially for general physical properties including size, surface area, weight, and strength retention to demonstrate substantial equivalence.
Conclusion
The device passed all applicable FDA Blue Book Memorandum G95-1 and ISO 10993-1 testing for the biological evaluation of medical devices. The results of the in vitro product characterization studies, bench testing and in vitro and in vivo biocompatibility studies, as well as the animal efficacy study demonstrate that the RMST Staple is safe and substantially equivalent to the predicate devices.
