No
The device description explicitly states it is a "mechanical device" and there are no mentions of AI, ML, image processing, or data training/testing related to algorithmic performance. The clinical trial mentioned is from 1995, predating widespread medical AI/ML applications.
Yes.
The device is intended for use during a surgical procedure (posterior ventricular catheter placement) to help the surgeon orient a ventricular catheter, which directly supports a therapeutic intervention.
No
No
The device description explicitly states that the Caroline Guide is a "mechanical device," indicating it is a hardware-based tool, not software.
Based on the provided information, the Caroline Guide is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD devices are used to examine specimens taken from the human body. The Caroline Guide is a mechanical device used during a surgical procedure (posterior ventricular catheter placement) to guide a catheter within the body. It does not analyze any biological samples.
- The intended use and device description clearly indicate a surgical guidance tool. The description focuses on its mechanical function in orienting a catheter during surgery.
- There is no mention of analyzing samples, reagents, or laboratory procedures. The information provided describes a physical tool used in an operating room setting.
Therefore, the Caroline Guide falls under the category of a surgical instrument or guidance device, not an In Vitro Diagnostic device.

Summary of Performance Studies
The mechanical accuracy of the Caroline Guide was tested in non-clinical studies by passing vent ricular catheters through the guide tube and confirming that the catheters maintain alignment with the frontal target point as they were advanced by hand. Pre-clinical testing demonstrated that the materials used in the construction of the Caroline Guide will withstand repeated decontamination, cleaning and sterilization cycles without adverse effects.
The Caroline Guide was tested in a clinical trial at the Universities of Iowa and Washington, involving both pediatric and adult patients. The trial results were reported in the peer reviewed scientific literature (Appendix F) in 1995. Non-commercial Caroline Guide prototypes have been used routinely in adult and pediatric cases since that time at the aforementioned university hospitals, as well as, at Children's Hospital, Washington University (St. Louis). No complications have been noted as a result of use of the Caroline Guide in pediatric patients.

Summary of the technological characteristics of the new device compared to the predicate device:
The modified Caroline Guide and original Caroline Guide (predicate device) have the following characteristics in common:
-
- same indications for use (except patient age)
-
- Same method for advancing the catheter into the ventricle
-
- same materials exposure to the patient during surgery
Description of non-clinical tests:
The mechanical accuracy of the Caroline Guide was tested in non-clinical studies by passing vent ricular catheters through the guide tube and confirming that the catheters maintain alignment with the frontal target point as they were advanced by hand. Pre-clinical testing demonstrated that the materials used in the construction of the Caroline Guide will withstand repeated decontamination, cleaning and sterilization cycles without adverse effects.
Discussion of clinical tests:
The Caroline Guide was tested in a clinical trial at the Universities of Iowa and Washington, involving both pediatric and adult patients. The trial results were reported in the peer reviewed scientific literature (Appendix F) in 1995. Non-commercial Caroline Guide prototypes have been used routinely in adult and pediatric cases since that time at the aforementioned university hospitals, as well as, at Children's Hospital, Washington University (St. Louis). No complications have been noted as a result of use of the Caroline Guide in pediatric patients.
In 1997, an "adult patient only" Caroline Guide received FDA 510(k) approval. This device is sold in conjunction with an adult burr hole localizer (the Delia Localizer). The Delia Localizer is not suitable for use in children. The modified Caroline Guide described in this submission is suitable for use in either adult (with the Delia Localizer) or pediatric (without the Delia Localizer) patients.
Conclusions drawn from the non-clinical and clinical tests:
These pre-clinical and clinical test data indicate that the new technologic features of the modified Caroline Guide do not adversely affect safety or effectiveness in a way that is consequential under the conditions of intended use.
