Intended Use

The IntraNovo Microcatheter is intended for the infusion of contrast media into all peripheral vessels up to and including the cervical vessels, all vessels in the lower and upper extremittes, and all coronary vessels. The Microcatheter is also intended for drug infusion in intra-arterial therapy and infusion of embolic materials for hemostasis. The Microcatheter should not be used in cerebral vessels.

Device Story

IntraNovo Microcatheter is a single-lumen infusion catheter for intravascular use. Device features PTFE inner liner, stainless steel coil reinforcement, polyether block amide outer shaft, and hydrophilic distal coating. Includes radiopaque marker band and polycarbonate hub. Available in 110 cm and 130 cm lengths. Operated by physicians in clinical settings for peripheral and coronary procedures. Delivered over-the-wire to target vessels. Used for contrast media delivery, drug infusion, and hemostasis via embolic material delivery. Manual tip shaping enabled by included stainless steel mandrel. Device facilitates access to smaller vessels due to reduced distal diameter (2.4 Fr) compared to predicate. Benefits include precise therapeutic agent delivery and vessel access.

Clinical Evidence

Bench testing only. No clinical data. Performance evaluated via 24 bench tests including guidewire compatibility, track force, coating durability/lubricity, burst pressure (static/dynamic), tensile strength, flow rate, kink resistance, radiopacity, torque, and particulate evaluation. Testing performed on T=0 and T=2 year accelerated aged samples. All tests passed.

#### 4. Device Description

The IntraNovo Microcatheter (the "IntraNovo 21" or the "Microcatheter") is an infusion catheter intended for intravascular use. The Microcatheter consists of a single lumen. The shaft consists of a lubricous inner liner made from polytetrafluoroethylene (PTFE) with a stainless steel coil over the inner liner. The outer liner consists of different lengths of colored polyether block amide with varying durometers hardness. A lubricious hydrophilic coating covers the distal end of the IntraNovo Microcatheter. One radiopaque marker band is placed at the distal end of the Microcatheter and above the stainless steel coil. A polycarbonate hub is attached to the proximal end of the Microcatheter with a strain relief placed over the distal end of the hub.

{4}------------------------------------------------

The device shaft has an outer diameter of 2.9 French size on the proximal end and 2.4 French size on the distal end with an inner diameter of 0.021" throughout the shaft. The device is available in lengths of 110 cm and 130 cm.

The following accessories are included with the Microcatheter: a stainless steel steam shaping mandrel to allow for manual shaping of the distal tip and a 3.0 mL syringe.

## 7. Discussion of Technological Characteristics

Both devices are equivalent with respect to their indications for use, fundamental design, technology and principles of operation, materials, performance, sterilization, and packaging.

The IntraNovo Microcatheter does differ from the predicate in outer diameter of 2.4 fr versus predicate's 2.7 fr, inner diameter of 0.021" versus the predicate's 0.025" and guidewire compatibility of a maximum 0.018" versus the predicate's 0.021". The following is a discussion of why no new issues of safety and effectiveness have been raised by these differences:

- 1. Difference on the distal outer diameter does not impact the product performance or modifies the intended use. The smaller size is intended to reach smaller target vessels in the anatomy. The Microcatheter's instructions for use indicate the minimum sizes of devices compatible with the Microcatheter outer diameter. This difference does not raise any new issues of safety and effectiveness.
- 2. Difference on the inner diameter does not impact on the product performance or modifies the intended use. The smaller size is intended to reach smaller target vessel in the anatomy. The Microcatheter's instructions for use indicate the maximum sizes of therapeutic agents compatible with the Microcatheter inner diameter. This difference does not raise any new issues of safety and effectiveness.
- 3. Difference in the guidewire compatibility does not impact on the product performance or modifies the intended use. Device lumen is smaller and therefore the maximum guidewire compatible is smaller. This difference does not raise any new issues of safety and effectiveness.

## 8. Testing Summary

{6}------------------------------------------------

The following bench tests were performed to evaluate the design elements and performance characteristics of the IntraNovo Microcatheter and to demonstrate substantial equivalence to the predicate device. The IntraNovo Microcatheter met the predetermined acceptance criteria. Testing was performed on non-aged devices (T=0) as well as on devices subject to 2 years of accelerated aging (T=2). Tests results show that the IntraNovo Microcatheter is substantially equivalent to the predicate device.

# 10. Biocompatibility

The IntraNovo Microcatheter is classified as an Externally Communicating Device, Circulating Blood, Limited Contact (<24) hours.

The final sterilized device is identical to IntraNovo 25 Microcatheter (K142817) in formulation, processing, sterilization, and geometry and no other chemicals have been added (e.g., plasticizers, fillers, color additives, cleaning agents, mold release agents).

Biocompatibility testing was not performed since the same materials of the IntraNovo 25 Microcatheter were used and biocompatibility testing results shown that these materials are biocompatible according to ISO 10993. The IntraNovo 25 Microcatheter was cleared under 510K number K142817 on 4/23/2015.
