Intended Use

The Dispatch Gold Coronary Infusion Catheter is intended for controlled and selective infusion of solution(s), including thrombolytic agents, into the vessel.

Device Story

Non-dilatation, over-the-wire infusion catheter; used for localized delivery of solutions (e.g., thrombolytics) into coronary arteries. Device features single lumen shaft with distally located inflation coil (20, 30, or 50 mm lengths) encapsulated by polyurethane sheath; inflation coil isolates delivery site. Inner tube accommodates coronary guide wires ≤ 0.014 inches for navigation. Radiopaque markers assist distal assembly placement; shaft markers indicate depth for femoral/brachial approaches. Proximal manifold includes inflation port, infusion port, and guide wire thru-port. Operated by physicians in clinical settings; device enables targeted therapy, potentially improving drug concentration at lesion site while minimizing systemic exposure.

Clinical Evidence

Bench testing only. Evaluation included infusion flow rate, inflation coil burst and distension, repeat inflation, bond integrity, bond tensile strength, shaft diameter, profile, withdrawal force, and proximal mark integrity. Results met or exceeded requirements.

Technological Characteristics

Over-the-wire infusion catheter; polyurethane sheath; platinum marker bands; manifold with luer lock fittings. Dimensions: coil lengths 20-50 mm, coil diameters 2.5-5.5 mm. Compatible with guide wires ≤ 0.014 inches. Non-dilatation design.

Indications for Use

Indicated for controlled and selective infusion of solutions, including thrombolytic agents, into coronary arteries in patients requiring localized drug delivery.

Regulatory Classification

Identification

A continuous flush catheter is an attachment to a catheter-transducer system that permits continuous intravascular flushing at a slow infusion rate for the purpose of eliminating clotting, back-leakage, and waveform damping.

## III. Device Description:

The Dispatch Gold Coronary Infusion Catheter is a non-dilatation, over-the-wire device designed for localized delivery of solution(s), through the openings located in the distal segment, into the selected coronary artery. The device has a single lumen shaft with a distally located inflation coil 20 mm, 30 mm or 50 mm in length. The number of coils increases with length. The inflation coil, encapsulated by a thin polyurethane sheath, may be inflated to further localize or isolate delivery to subselected vasculature.

The lumen of the shaft is used to transport solutions, as well as to house an inner tube and inflation tube running the length of the shaft and situated concentrically within the lumen. The inner tube permits the use of coronary guide wires $\leq 0.014''$ to advance the device through the anatomy to the intended infusion site. The distal tip is tapered to facilitate the advancement of the device through the vasculature.

Radiopaque markers are located at both the proximal and distal ends of the balloon coil to assist in the placement of the device's distal assembly. Shaft locating markers are printed proximally on the outer shaft of the catheter to ensure proper placement of the distal infusion segment with respect to the guide catheter. One marker is designated by two parallel white stripes located at 100 cm and the other is designated by a single white stripe located at 90 cm from the distal tip for femoral and brachial approaches respectively.

The proximal portion of the device consists of a manifold with a blue inflation port and a yellow infusion port. The inner lumen is connected to an unmarked thru port for guide wire insertion, which also has a luer lock fitting for the connection of a Y-adapter if desired.

## IV. Intended Use:

The Dispatch Gold Coronary Infusion Catheter is intended for controlled and selective infusion of solution(s), including thrombolytic agents, into the vessel.

## V. Summary of Technological Characteristics:

The Dispatch Gold Coronary Infusion Catheter is a modification of the currently marketed Dispatch Coronary Infusion Catheter. The two catheters look and function alike, however the Dispatch Gold has a smaller overall outer shaft dimension and distal profile. The color of the Dispatch Gold shaft will be yellow instead of clear (natural). Other modifications include the configuration of the infusion openings and the length of the platinum marker band. The Dispatch Gold will be available in coil lengths of 20 mm, 30 mm and 50 mm with coil diameters ranging from 2.5 mm to 5.5 mm.

## VI. Non-clinical Test Summary:

Testing and evaluation included infusion flow rate, inflation coil burst and distension, repeat inflation of coil assembly, catheter bond integrity and bond tensile strength, shaft diameter, inflation coil assembly profile, catheter withdrawal force and proximal mark integrity test. Test results verified that the Dispatch Gold Coronary Infusion Catheter met or exceeded all minimum requirements and is adequate for its intended use. The Dispatch Gold Coronary Infusion catheter is considered to be substantially equivalent to the currently marketed SCIMED Dispatch Coronary Infusion Catheter and the currently marketed SCIMED UltraFuse Coronary Infusion Catheter based on a comparison of intended use, design and the results of the in vitro testing and evaluation.
