Intended Use

The Glidesheath Slender is indicated to facilitate placing a catheter through the skin into the radial artery.

Device Description

The Glidesheath Slender consists of an introducer (sheath and a dilator), which are packaged together with an entry needle, mini guide wire and guide wire inserter. The Glidesheath Slender devices (all sheath sizes) are used to facilitate placing a catheter through the skin into the radial artery. The sheath and dilator contain bismuth, making these devices visible under fluoroscopy. The sheath is coated with hydrophilic coating to minimize frictional resistance when inserting or removing the sheath from the patient's blood vessel.

The entry needle (cannula) is used to gain access to the radial artery for placement of the mini guide wire. The entry needle is offered in either the stainless steel (SS) entry needle version or the Surflo (SR) IV catheter (which includes a needle). There are two different types of stainless-steel entry needles that are available in various gauges and lengths. The two needle types are referenced in the documentation as TPC and TRI. These initials are only used in internal Terumo documents.

The mini guide wire is used for placement of the sheath and dilator into the radial artery. The mini guide wire is offered in three versions made out of three materials, either a stainless-steel spring coil model (stainless steel), a nitinol model with palladium tip (nitinol) or a polyurethane plastic model with a nitinol core (plastic).

During either a diagnostic or interventional catheterization procedure, a physician will perform the following procedure. The mini guide wire is inserted through a cannula placed in the patient's blood vessel. A guide wire inserter is provided to assist in insertion of the mini guide wire into the cannula. Following guide wire insertion, the cannula is removed, and the sheath and dilator are then inserted over the mini guide wire and into the blood vessel. The mini guide wire is then withdrawn from the vessel. The dilator maintains the integrity of the sheath and dilates the blood vessel during insertion. Once the sheath is situated in the vessel, the dilator is removed, and an appropriate catheter can then be inserted through the sheath.

The entry needle, the mini guide wire and the guide wire inserter are all accessories to the Glidesheath Slender sheath/dilator. The accessories for a given product code are provided with the Glidesheat Slender sheath/dilator in an individual package and sterilized together.

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

The document describes non-clinical performance testing, which typically involves testing of device units according to engineering standards rather than a "test set" of patient data. The specific number of units tested for each performance test item is not provided in this summary. The data provenance is internal to the manufacturer (Terumo Medical Corporation) and follows recognized international and in-house standards. This is not patient data, so "country of origin" and "retrospective/prospective" are not applicable in the usual sense for clinical studies.

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

This information is not applicable as the document explicitly states: "This 510(k) does not include data from clinical tests." The performance testing described is engineering and biocompatibility testing, where "ground truth" is established by adherence to specified physical and chemical properties and compliance with recognized standards.

4. Adjudication Method for the Test Set:

This information is not applicable as clinical data or expert review of cases is not part of this 510(k) summary.

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

No, an MRMC comparative effectiveness study was not done. The document explicitly states: "This 510(k) does not include data from clinical tests." Therefore, there is no information on how much human readers improve with AI vs. without AI assistance.

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

This is not applicable as the device is a physical medical instrument (catheter introducer), not an AI algorithm or software.

7. The Type of Ground Truth Used:

For the performance testing, the "ground truth" is established by:

  • International Standards: ISO 11070:2014, ASTM F640-12, ISO 11135:2014, EN ISO 10993-1, EN ISO 10993-7:2008.
  • FDA Guidance: FDA PTCA Guidance, FDA Guidance on Use of International Standard ISO 10993-1.
  • In-house standards: Internal specifications developed by Terumo Medical Corporation.

These standards and guidances define acceptable physical, mechanical, chemical, and biological properties for device components.

8. The Sample Size for the Training Set:

This is not applicable as the device is a physical medical instrument and does not involve a "training set" in the context of machine learning or AI.

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

This is not applicable for the same reason as above.
