The Glidesheath is used to facilitate placing a catheter through the skin into a vein or artery including but not limited to the radial artery.
The Entry Needle is an accessory device which is used to gain access to the vein or artery including but not limited to the radial artery, for placement of the Mini Guide Wire.
The Mini Guide Wire is an accessory device which is used for placement of the sheath into the vein or artery including but not limited to the radial artery.
The Glidesheath is comprised of an introducer sheath and a dilator. The Glidesheath is coated with a hydrophilic coating to reduce the frictional resistance of the sheath when inserting or removing the sheath from the patient's blood vessel. The Sheath and Dilator contain bismuth, making these devices visible under fluoroscopy. The Glidesheath is used to facilitate placing a catheter through the skin into a vein or artery including but not limited to the radial artery.
The Entry Needle is an accessory device which is used to gain access to the vein or artery including but not limited to the radial artery, for placement of the Mini Guide Wire.
The Mini Guide Wire is an accessory device which is used for placement of the sheath into the vein or artery including but not limited to the radial artery. The Guide Inserter which is attached to the Mini Guide Wire holder is used to straighten out the wire.
Accessories to the Glidesheath are the metal entry needle and the mini guide wire. Both the metal entry needle and the mini guide wire are packaged with the Glidesheath in a pouch prior to sterilization.

Study Details for Acceptance Criteria Proof:
-
Sample size used for the test set and data provenance:
- The document does not specify sample sizes for individual performance tests (e.g., how many needles were tested for joint strength).
- It also does not indicate the data provenance (e.g., country of origin, retrospective or prospective). Given the nature of bench testing, it's typically performed in a laboratory setting by the manufacturer.
-
Number of experts used to establish the ground truth for the test set and their qualifications:
- This information is not provided. For mechanical and biocompatibility testing, ground truth is typically established by adhering to recognized international standards and internal quality control specifications, rather than relying on expert consensus in the way clinical studies do. The "experts" would be the engineers and scientists performing and interpreting the standardized tests.
-
Adjudication method for the test set:
- This information is not applicable or not provided. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies or studies involving subjective interpretations (e.g., image reading). The listed performance tests are primarily objective, quantitative, or qualitative assessments against defined standards.
-
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and the effect size:
- No, an MRMC comparative effectiveness study was not conducted. This type of study is relevant for diagnostic imaging devices or devices where human interpretation is a key component, often comparing human performance with and without AI assistance. This document describes a physical medical device (introducer sheath) that does not involve diagnostic interpretation or AI.
-
If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- No, a standalone algorithm performance study was not done. This device is a physical mechanical instrument and does not incorporate an AI algorithm.
-
The type of ground truth used:
- The ground truth for most performance tests (Needle, Guide Wire, Dilator, Sheath, Inserter, System) would be based on engineering specifications, material science standards, and functional requirements for similar medical devices.
- For Biocompatibility, the ground truth is established by international biological evaluation standards (ISO 10993), which define acceptable thresholds for biological responses (e.g., absence of cytotoxicity, genotoxicity, etc.).
- For Sterilization, the ground truth is based on sterilization validation standards (ANSI/AAMI/ISO 11135) to achieve a defined Sterility Assurance Level (SAL) of 10^-6.
-
The sample size for the training set:
- This is not applicable. The Glidesheath is a physical medical device, not an AI or machine learning model that requires a "training set."
-
How the ground truth for the training set was established:
- This is not applicable for the same reason as point 7.
