Catheter-based Familiar venous access
Nonthermal No thermal energy at the target
Nontumescent Designed without tumescent anesthesia
No implant Device withdrawn after delivery
Clinical context

Visible disease is often the surface expression of a deeper hemodynamic problem.

The practitioner challenge is not simply identifying a visible vein. It is treating the target vein while protecting surrounding tissue and maintaining an efficient workflow.

Hemodynamic context

Reflux turns a local valve failure into a progressive pressure problem.

When valve competence is lost, retrograde flow increases venous pressure, distends the vessel, and can drive visible and symptomatic disease.

Inside the vein

Valve incompetence changes flow, pressure, and vessel geometry.

A competent valve supports unidirectional return. When it fails, reflux and elevated ambulatory venous pressure can contribute to dilation, edema, and progressive symptoms.

Current procedural trade-offs

Today's venous treatments ask practitioners to balance efficacy, invasiveness, and workflow.

Thermal, adhesive, and chemical approaches each bring distinct procedural considerations.

Thermal, RFA & laser

Energy dependent

  • Typically requires tumescent anesthesia
  • Heat-related nerve and skin considerations
Adhesive closure

Implant dependent

  • Permanent material remains in the vessel
  • Hypersensitivity and phlebitis considerations
Chemical foam

Dispersion dependent

  • Distribution can extend beyond the target segment
  • Staining and thrombophlebitis considerations
Single-balloon mechanism

One balloon with integrated coils supports a nonthermal, nontumescent treatment approach.

Design priorities
Priority 01

Tissue preservation

A nonthermal mechanism avoids applying heat at the treatment target.

Priority 02

Nontumescent workflow

Designed to treat without tumescent anesthesia.

Priority 03

No permanent implant

The catheter and single balloon are withdrawn after treatment.

Practice integration

Designed to fit established superficial venous workflows.

Familiar access
Catheter-based technique builds on established venous procedural skills.
Single-balloon treatment
Integrated coils provide a clear, easy-to-visualize mechanism.
Clear patient conversation
Nonthermal, nontumescent, no permanent implant offers a straightforward treatment concept.
In the clinical conversation
