Intended Use

The intended use of the New Device is to establish a path of entry for minimally invasive instruments. Instruments provided with a stopcock are intended for insufflation of the operative space when the trocar is in place.

The ENDOPATH® Dilating Tip Trocar has application in general, thoracic, gynecologic, or other minimally invasive surgical procedures to establish a path of entry for minimally invasive instruments.

The ENDOPATH® Dilating Tip Trocar has application in abdominal, thoracic, and gynecologic minimally invasive surgical procedures to establish a path of entry for minimally invasive instruments.

Device Description

The ENDOPATH® Dilating Tip Trocar consists of two main sub-assemblies: an obturator sub-assembly and a sleeve sub-assembly.

The obturator consists of a sharp flat blade tip or pyramidal tip and a spring loaded shield. The shield is designed to cover the flat blade or pyramidal tip to protect internal structures from puncture or laceration once the abdominal or thoracic cavity has been entered.

The sleeve subassembly has an inner gasket seal or flapper door seal and an outer gasket seal to maintain pneumoperitoneum when instrumentation is inserted and withdrawn through the cannula during a surgical procedure. Some instruments are provided with a stopcock for insufflating the operative space and a flapper door lever to allow quick desufflation. Integral threads along the outside diameter of the cannula portion of the sleeve provide a retention mechanism to stabilize the sleeve in tissue.

The ENDOPATH® Dilating Tip Trocar shall be provided in a variety of sizes from 3mm to 12mm in diameter and 65mm to 150mm in length.

AI/ML Overview

Here's an analysis of the provided text regarding the acceptance criteria and study for the ENDOPATH® Dilating Tip Trocar:

1. Table of Acceptance Criteria and Reported Device Performance:

Acceptance Criteria (Implied)Reported Device Performance
Mating of obturator with sleeveAcceptable performance
Insertion into operative cavityAcceptable performance
Removal of obturator from sleeveAcceptable performance
Security of sleeve in tissueAcceptable performance
Maintenance of pneumoperitoneum of the operative spaceAcceptable performance

Note: The document explicitly states "Pre-clinical laboratory evaluations were performed to ensure that the device can be used as designed. The studies demonstrated acceptable performance to the Predicate Device..." The acceptance criteria are not quantified with specific thresholds (e.g., "no more than X force required for insertion," "no leaks exceeding Y ml/min"). Instead, the performance is reported as "acceptable" in comparison to a predicate device.

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

  • Sample Size: Not specified.
  • Data Provenance: The studies were "Pre-clinical laboratory evaluations." This suggests the tests were conducted in a laboratory setting, likely in the US (given the submission to the FDA in Cincinnati, Ohio). It is a prospective study as newly manufactured devices were tested.

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

  • Not applicable/Not specified. The "ground truth" for this type of device (a surgical trocar) would be based on engineering specifications and functional testing, not expert consensus on medical images or clinical outcomes in the same way an AI diagnostic tool would.

4. Adjudication Method for the Test Set:

  • Not applicable/Not specified. As noted above, the testing is functional and engineering-based, not reliant on human interpretation or adjudication in the medical sense.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:

  • No, an MRMC comparative effectiveness study was not done. This type of study is relevant for diagnostic or AI-assisted interpretation tools, not for a physical surgical device like a trocar.

6. If a Standalone (i.e., algorithm only without human-in-the loop performance) was done:

  • Not applicable. This device is a physical surgical instrument, not a software algorithm.

7. The Type of Ground Truth Used:

  • The ground truth (or more appropriately, the standard) for evaluation was likely established through engineering specifications for the device's functional components and comparative performance against a predicate device. The studies "demonstrated acceptable performance to the Predicate Device." This implies the predicate device's established performance served as the benchmark.

8. The Sample Size for the Training Set:

  • Not applicable. This is not an AI-based device, so there is no "training set."

9. How the Ground Truth for the Training Set was Established:

  • Not applicable. As above, there is no "training set."

TechnologicalcharacteristicsThe technological characteristics of the New Device are the same as thePredicate Device.
PerformancedataPre-clinical laboratory evaluations were performed to ensure that the devicecan be used as designed. The studies demonstrated acceptable performance tothe Predicate Device in mating the obturator with the sleeve, insertion into theoperative cavity, removal of the obturator from the sleeve, security of thesleeve in tissue, and maintenance of pneumoperitoneum of the operative space.
ConclusionBased on the 510(k) summaries and 510(k) statements (21 CFR §807) and theinformation provided herein, we conclude that the New Device is substantiallyequivalent to the Predicate Device under the Federal Food, Drug andCosmetic Act.
