FDA approved: An AGENT of change for ISR treatment

AGENT Drug-Coated Balloon expands treatment options for physicians and their patients by delivering a targeted anti-proliferative drug dose, without introducing an extra layer of metal.

How it works

Why choose AGENT Drug-Coated Balloon? 

ISR treatment option expansion

~10% of PCIs are complicated by in-stent restenosis (ISR)1. Currently, 82% of patients with ISR receive another stent.2 Yet repeat intervention is associated with a higher risk of target lesion revascularization.3

For patients with ISR, placing additional stents increases risks including thrombosis⁴ and future ISR.⁵ ⁶ Coronary drug-coated balloons (DCBs) provide a proven alternative and have been used to treat more than 1 million patients worldwide.⁷

Which may result in a reduced rate of medication-related bleeding complications⁹

Comparing DCB to DES when treating ISR

DCBs present an advantage when compared to bare-metal stents and drug-eluting stents in that they do not introduce an additional metal layer that may cause potential complications (including fracture, malposition, and thrombosis).⁵

The right drug. The right delivery method. ​

AGENT is designed with a novel excipient, sharp-edge structure, and uniform crystalline formulation. Its proprietary TransPax™ coating technology optimizes the three phases of drug delivery: transfer, absorption, and retention.

Paclitaxel, the drug used in AGENT and the majority of DCBs worldwide, is better suited for a Coronary DCB Application than Sirolimus:

Novel excipient maximizes balloon-to-vessel wall transfer and minimizes downstream particulates.

Targeted transfer

  • Paclitaxel is more durable, repels water, and dissolves under hydration (hydrophobic).10,11
  • Novel excipient (ATBC) maximizes balloon-to-vessel wall transfer.
Sharp microscopic Paciltaxel (PTX) structure that enhances tissue absorption.

Rapid absorption

  • Paclitaxel has a higher affinity for fatty tissue (lipophilic), accelerating drug tissue absorption.12 
  • Needle like coating improves tissue penetration.
Uniform crystalline formulation maintains the Paciltaxel through the healing process.

Sustained retention

  • Paclitaxel has a lower dissolution rate and higher chemical stability that enables sustained release.13,14 
  • Crystalline formulation maintains therapy throughout the healing process. 

TransPax™ Coating Technology

With the right balance of hydrophilic and hydrophobic characteristics, our proprietary TransPax Coating Technology is designed to maximize drug transfer to the target vessel wall and delivers the right amount of treatment exactly where it’s needed.

TransPax coating is a combination of:

  • Low dose paclitaxel at 2µ/mm2
  • Novel excipient Acetyl Tributyl Citrate (ATBC)
  • Proprietary manufacturing process
Uniform crystalline formulation maintains the Paciltaxel through the healing process.

Exceptional deliverability

AGENT reduces time to lesion, which allows for maximized drug tissue concentration and minimized downstream particulates, reducing the risk of embolization. Features include: 

Laser Bonded Tip

  • Improves crossability and reduces tip catch.

Bi-segment Inner Shaft

  • Improves trackability in tortuous distal anatomy


  • Improves tracking with proprietary lubricious coating


  • Efficient coating technology
AGENT DCB is designed for effortless deliverability with its Laser Bonded Tip, Z Glide for enhanced trackability, and a flexible Bi-Segment Inner Shaft.

Clinical highlights



AGENT IDE is a prospective, multicenter, randomized controlled trial in the United States to evaluate the safety and effectiveness of the AGENT™ DCB compared to balloon angioplasty in patients with in-stent restenosis (ISR).15  At one year, AGENT DCB demonstrated statistically lower event rates15:

50% risk reduction for TLR

50% risk reduction in TLR

(13.0% vs. 24.7%, P=0.0005)

49% risk reduction for TV-MI

AGENT IDE Trial Primary Endpoint16 

AGENT DCB showed statistically superior outcomes compared to balloon angioplasty for TLF at 1-year (17.9% versus 28.6% P= 0.003).

TLF relative risk reduction from using AGENT DCB was approximately 41%.

Featured clinical publications

The American College of Cardiology (ACC) Interventional Council 

In February 2023, The American College of Cardiology (ACC) Interventional Council released the recommendation that all cardiac cath labs should have imaging capabilities. The review proposes PCI best practices and advocates for broader use of IVI technologies.


The recent RENOVATE-COMPLEX-PCI study provides evidence in favor of using intravascular imaging-guided PCI to address complex coronary artery lesions. At the 3-year follow-up, intravascular imaging-guided PCI demonstrated a reduced risk of target vessel failure when compared to angiography-guided PCI.¹
