Intended Use

The Trellis™ Infusion System is intended for controlled and selective infusion of physician-specified fluids, including thrombolytics, into the peripheral vasculature.

Device Story

The Trellis Infusion System is a multi-lumen catheter designed for peripheral vascular infusion. It features two distal compliant balloons that inflate to isolate a specific treatment zone. A central through-lumen accommodates a 0.035" guidewire. The system includes a sheathed, shape-set Nitinol Dispersion Wire connected to an integral Oscillation Drive Unit. The physician operates the device to isolate the vessel segment, infuse fluids, and activate the drive unit to oscillate the wire at up to 25 Hz. This oscillation disperses the infused fluid within the isolated zone. The device is used by physicians in clinical settings to enhance the delivery of thrombolytics or other fluids, potentially improving therapeutic efficacy while maintaining localized concentration.

Clinical Evidence

No human clinical data provided. Pre-clinical in vivo testing was conducted in animal arteries to assess acute safety, feasibility, fluoroscopic visualization, and histologic effects. Results showed no serious vessel wall injury for either the Trellis or the predicate. Histological examination indicated that endothelial cell removal was lower with the Trellis Infusion System compared to the predicate device.

Technological Characteristics

Multi-lumen catheter with two compliant balloons and infusion holes. Dispersion component uses a shape-set Nitinol cable. Oscillation Drive Unit provides mechanical oscillation up to 25 Hz. Materials are biocompatible and previously cleared. Electrical safety and electromagnetic compatibility testing performed. Device is compatible with 0.035" guidewires.

Indications for Use

Indicated for patients requiring controlled and selective infusion of physician-specified fluids, including thrombolytics, into the peripheral vasculature.

Regulatory Classification

Identification

#### Device Description

The Trellis Infusion Catheter enables the physician to isolate a treatment region, infuse a physician-specified fluid, and disperse the fluid by means of oscillation of a Dispersion Wire. The Isolation/Infusion component is a multi-lumen catheter with two compliant balloons at the distal end and infusion holes located between these balloons. When inflated, the compliant balloons isolate a treatment zone to maintain concentration of the infused fluid. The device also has a central through-lumen that is compatible with a 0.035" guidewire. The Dispersion Wire component is a sheathed,

{5}------------------------------------------------

shape-set Nitinol cable that provides oscillation when activated. The Dispersion Wire is connected to an integral Oscillation Drive Unit which oscillates the Dispersion Wire up to 25 Hertz within the isolated region to further disperse the infused fluid.

## Materials

All materials used in the manufacture of the Trellis are suitable for this use and have been used in numerous previously cleared products.

# Testing

The following testing was conducted to ensure the Trellis met all specifications:

- Tensile Testing .
- Torque-to-Fail Testing .
- Catheter Trackability and Dispersion Wire Insertion ●
- Guidewire Compatibility ●
- Balloon Compliance and Burst Testing ●
- t Device and Battery Life Testing
- Catheter Leak Testing
- Infusion Flow Rates
- Catheter Corrosion Testing .
- Electrical Safety and Electromagnetic Compatibility Testing .

The results of the above tests demonstrated that the device is as safe & effective as the legally marketed predicate device. All components, subassemblies, and/or full devices met the required specifications for the above tests.

# Pre-clinical in vivo Testing

Testing of the Trellis and the predicate was conducted in animal arteries to assess acute safety, feasibility of introduction into the vascular system, the ability to visualize the devices under fluoroscopy, adverse reactions and/or device failures, and to examine acute histologic effects or injury to a normal vessel wall. Histological examination of treated vessels demonstrated that neither device caused serious injury to the vessel wall. Endothelial cell removal was greater in the predicate device than with the Trellis Infusion System.

#### Summary of Substantial Equivalence

The Trellis is equivalent to the predicate products from SciMed, Merit Medical, AngioDynamics, and Lake Region. The indications for use, basic overall function, methods of manufacturing, and materials used are substantially equivalent. Bacchus Vascular, Inc. believes the Trellis is substantially equivalent to existing legally marketed devices.
