Paclitaxel Coated-PTCA Balloon Catheter

The AGENT Paclitaxel Coated-PTCA Balloon catheter  is the newest advance in drug-coated balloon technology.
Mechanism of action phases

The AGENT™ Paclitaxel Drug Coated Balloon catheter, with its innovative TransPax™ coating technology1, provides a targeted, therapeutic dose of proven, anti-proliferative Paclitaxel to the lesion2. It was designed to minimise downstream particulates while maintaining the outstanding deliverability you’ve come to expect with Boston Scientific products3.

Product Details

The AGENT™ Paclitaxel-Coated balloon catheter, built on the Emerge™ PTCA Balloon Catheter for exceptional deliverability, is indicated for Percutaneous Transluminal Coronary Angioplasty (PTCA) in the coronary arteries to treat in-stent restenosis (ISR) and de novo / small vessel disease.
Optimal dose of 2µg/mm2 compared to 3µg/mm2 of market leading DCBs efficiently achieves sustained benefits of Paclitaxel2 over time.

Optimized Drug Transfer

  • TransPaxTM coating ensures targeted delivery of Paclitaxel†
  • Optimal dose of 2 μg/mmcompared to 3 μg/mmof market leading DCBs‡

Outstanding Deliverability5

  • AgentTM DCB offers exceptional deliverability leveraging the EMERGETM PTCA Catheter:
  • Designed to navigate and cross challenging lesions
    • Ultra-low tip profile
    • Bi-segment inner shaft: flexible distal segment and pushable  proximal segment.

Enhanced Coating Integrity

  • Balanced hydrophobic and hydrophilic properties of Trans PaxTM coating ensures balloon reaches the lesion with the optimal amount of drug for your patient.
  • Fewer particulates are lost distally during the procedure§.

What is TransPax™

The TransPax coating is a proprietary formulation of Paclitaxel and a citrate ester excipient (acetyl tributyl citrate – ATBC). It leverages Boston Scientific’s history and expertise with paclitaxel and drug coating.

Boston Scientific’s TransPax™ is the coating on both IC and PI Drug-coated balloons (DCB). Ranger™ Paclitaxel-Coated PTA Balloon Catheter is Boston Scientific's DCB for Peripheral Interventions.


What is the Delivery System

AGENT™ Drug-Coated Balloon is built on the Emerge™ balloon catheter technology which combines the best of Boston Scientific balloon technologies to offer exceptional deliverability5 with an ultra-low tip profile and is designed to navigate and cross even the most challenging lesions with unprecedented ease.

Agent Infographic

How it works*

Once the DCB has been deployed, the durable TransPax coating:

1. Ensures that a consistent drug dose is delivered to a lesion*

2. Binds with microtubules to inhibit proliferation of smooth-muscle cells*

3. Enables healing by selectively impacting cells that cause restenosis while allowing healing of endothelial cells*

Safety and performance*

Enhanced Coating Integrity

Designed to improve coating durability and drug transfer efficacy, allowing for a lower dosage of Paclitaxel*

Optimized Drug Transfer

Optimized Drug Transfer°

Balanced hydrophobic and hydrophilic properties allow efficient drug transfer to the vessel wall

Minimized Systemic Loss

Minimized Systemic Loss§

Less particulates and systemic loss while optimizing arterial tissue Paclitaxel levels.
