Amplifivascular offers the Amplifi Vein Dilation System, a wearable external blood pump that temporarily enlarges a patient’s vein before arteriovenous fistula (AVF) creation. By delivering controlled flow through dual catheters, the device rapidly dilates veins, increasing eligibility for AVF, shortening maturation time, and reducing early failure rates, and is removed prior to surgery.

Problem
Many hemodialysis patients have veins that are too small or unsuitable for creating an arteriovenous fistula (AVF), leading to ineligibility for the preferred vascular access or a high risk of fistula maturation failure.
Solution
The Amplifi Vein Dilation System is a wearable, external blood pump designed to temporarily enlarge a patient’s vein before AVF creation. By delivering controlled blood flow through inflow and outflow catheters, the device rapidly dilates the target vein using established hemodynamic principles. The system is removed prior to surgery, leaving a larger, more robust vessel that can improve eligibility for AVF, shorten time to maturation, and reduce early failure rates. This pre‑procedural preparation aims to extend the primary patency of the fistula, providing more reliable long‑term access for hemodialysis.
Target Audience
Primary customers are vascular surgeons, interventional nephrologists, and dialysis centers that perform AVF creation and require reliable pre‑operative vein preparation.
Features
- Wearable external blood pump with rechargeable battery and handheld controller
- Dual catheters (inflow and outflow) that create controlled circulatory flow to dilate veins
- Proprietary hemodynamic algorithm for rapid, predictable vein enlargement
- Device is removable before AVF surgery, leaving no permanent implant
- Designed to increase vein diameter and blood flow, supporting higher AVF success rates
- Compact, portable system suitable for use in outpatient or clinical settings
