Intended Use
The Rebar™ Micro Catheter is intended for the delivery of interventional devices or contrast media into the vasculature of the peripheral and neuro anatomy.
Device Description
The Rebar" Micro Catheter is an endhole, single-lumen catheter designed to be introduced over a steerable guidewire into the vasculature. The proximal end of the catheter incorporates a standard luer adapter to facilitate the attachment of accessories. The catheter has a semi-rigid proximal shaft which transitions into the flexible distal shaft to facilitate the advancement of the catheter in the anatomy. Single or dual radiopaque markers at the distal end facilitate fluoroscopic visualization. The outer surface of the catheter is coated to increase lubricity.
More Information

No
The device description and performance studies focus on the physical characteristics and mechanical performance of a micro catheter, with no mention of AI/ML capabilities or data processing beyond fluoroscopic visualization.

No
The device is intended for the delivery of other interventional devices or contrast media, rather than directly providing a therapeutic effect itself.

No
The device is described as intended for the delivery of interventional devices or contrast media, which are therapeutic or diagnostic tools, not for performing diagnosis itself.

No

The device description clearly outlines a physical catheter with a lumen, shaft, luer adapter, radiopaque markers, and coating. The performance studies focus on bench testing of the physical properties of the catheter.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for the delivery of interventional devices or contrast media into the vasculature. This is a therapeutic or procedural use, not a diagnostic test performed on samples taken from the body.
  • Device Description: The description details a catheter designed for insertion into blood vessels. This is a medical device used in vivo (within the body).
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information based on laboratory testing.

IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for the diagnosis, monitoring, or treatment of diseases or conditions. This device's function is to facilitate procedures within the body.

| Indication for Use
(IFU) Statement | The Rebar Micro Catheter is intended for the controlled
selective infusion of physician-specified therapeutic
agents or contrast media into the vasculature of the
peripheral and neuro anatomy. | The Rebar Micro
Catheter is intended
for the delivery of
interventional devices
or contrast media into
the vasculature of the
peripheral and neuro
anatomy. |
| Principles of
Operations | The Rebar™ Micro Catheter is inserted within a guide
catheter that has already been advanced to the desired
location. The user connects a hemostatic side arm
adapter to the guide catheter to prevent backflow of
blood during insertion of the micro catheter. The user
also connects a one-way stopcock to the hemostatic
side arm adapter to continuously flush the guide
catheter with saline. The outer surface of the catheter
must be hydrated, and the catheter lumen must be
flushed with heparinized saline by attaching a saline
filled syringed to the catheter hub.
The user selects an appropriate steerable guidewire,
inserts it into the hub of the micro catheter and
advances the guidewire in the lumen. The stopcock is
closed, and the hemostatic valve loosened. The
guidewire and micro catheter are introduced as a unit
through the hemostatic port of the hemostatic sidearm
adapter into the lumen of the guiding catheter. The
guidewire/catheter assembly is advanced to the distal
tip of the guiding catheter or until the desired site has
been reached. The valve around the micro catheter is
tightened enough to prevent backflow but allowing
some movement through the valve by the micro
catheter. The stopcock is then opened. When ready to
infuse, the user withdraws the guidewire completely
from the micro catheter. A syringe with the desired
infusate is connected to the hub of the micro catheter.
The user infuses the site as required and then removes
and discards the micro catheter. | Same |

Biocompatibility

Biocompatibility test results for subject Rebar Micro Catheter will be leveraged and adopted for the design change to the hub. The new hub material is Trogamid, which is found within other cleared Medtronic Neurovascular product lines, and is considered indirect patient contact. Biocompatibility data can be leveraged per ISO 10993-1 from the React™ 71 Catheter (K182101), as the modified hub has the same nature and duration of contact, has similar geometry, and is identical in formulation, processing, and sterilization. Slight dimensional changes that were made to the inside of the hub, outside of the hub, and luer thread are minor and do not impact biocompatibility data. Additionally, the new UV adhesive included in the manufacturing process for the hub is nonpatient contacting, thereby not impacting biocompatibility results of subject Rebar™ Micro Catheter. Both materials were found to be non-hemolytic and non-cytotoxic per Marathon™ Flow Directed Micro Catheter (K202318).

Performance Data- Animal:

Animal testing was not included in the subject submission. The differences in technological characteristics do not raise new questions of safety and effectiveness as demonstrated through non-clinical bench testing using wellestablished scientific methods.

Performance Data - Clinical:

Clinical testing was not included in the subject submission. The differences in technological characteristics do not raise new questions of safety and effectiveness as demonstrated through non-clinical bench testing using wellestablished scientific methods.

Conclusion

The differences in technological characteristics do not raise new questions of safety and effectiveness as demonstrated through non-clinical bench testing using well-established scientific methods. The information provided in this submission supports the proposal of substantial equivalence for the Rebar™ Micro Catheter.
