VE - Electric Balloon Wrapper

Model VE Machine Base

A full-featured balloon wrapping (aka folding) machine with electric actuation, for pleating and compressing catheter balloons
  • Full recipe control over balloon wrapping process
  • Powerful and intuitive interface
  • Temperature-controlled stainless steel dies
  • Minimal maintenance with consistent results

Our most productive balloon wrapping machine pairs a high-performance microcontroller with a touchscreen HMI to provide intuitive and flexible control of the balloon wrapping process. All process settings are under software recipe control.

Pleating and compression stations are both actuated by stepper motors, with encoder-measured diameter and transducer-measured actuating force. Force or diameter control of balloon compression uses the same electronic system made famous by our stent crimpers.

A complete machine includes a Model VE machine base, an electrically-actuated pleating station, and an electrically-actuated compression station. The pleating and compression stations are chosen based on the balloon diameter and length. Our engineers will help you choose the best pleating and compression stations for your application.

Pleating and compression die temperature can be set from ambient to 100°C. Balloon inflation pressures can be set up to 100 psi. Model VE is used with balloons for PTCA, PTA, heart valve delivery, and many other applications, with diameters up to 45 mm, and working lengths up to 310 mm. Pleating stations can be easily swapped on the VE machine base for product changeover. Knowledge Base: Balloon Wrapping Basics

Custom Die Design is used for all pleating dies in the VE balloon wrapper. The customer is provided with a table to fill in the details of a balloon range, such as distal seal diameter, double wall thickness, inflated diameter, and desired number of wings. One or more stainless steel die sets are then designed to accommodate the largest end of the range. All dies are hardened and electropolished. Knowledge base: Pleating Die Customization

The model VE balloon wrapper is a refinement of the Blockwise model VC. Process recipes running on the VC machine can be directly transferred to the VE, with the same results. Improvements in the VE machine are: fully electronic actuation of stations, better control of user access and manual mode, better reliability, better error logging, and easier calibration.

A product carrier on a manually-powered linear slide holds the catheter and allows the operator to quickly align the balloon catheter to control which parts of the product are pleated and compressed.

Optional Features

Integrated leak tester

Allows user to perform vacuum leak check at the end of the wrapping process, without disconnecting the catheter, and with minimal added trapped-air volume

HMI Capabilities

A touchscreen HMI (human-machine interface) allows the user to enter settings in “recipes” that specify a set of parameters for the balloon wrapping process. Calibration and gauge checks are easy. Manual mode allows direct commands without a recipe. Recipe editing, calibration, and manual operation can be password-protected.Knowledge Base: VE Wrappers Screens and Recipe Setup

The process is initiated by either the START button or the Simpluer switch, as desired. The machine prompts the operator to move the catheter through the pleating and compression stations. An information box shows the current state of the process.

  • Up to 100 recipes
  • Easy calibration
  • Password access to critical settings
  • Manual mode operation
  • Error reporting and logging
  • Optional barcode scanner for recipe selection
  • Optional leak check steps

Calibration and checking of diameter, force, and pressure, and temperature is very quick and easy. Specific screens for checking or calibrating walk the user through the process. The intuitive process reduces the likelihood of calibration mistakes. User-supplied reference instruments for diameter (pins) force (weights), pressure, and temperature are required.

The VE machine requires no maintenance. The pleating and compression mechanisms also require no maintenance - just keep them clean. Do not use in a dusty or dirty environment, and blow with compressed air. Clean the center opening with 99% isopropyl alcohol on a lint-free swab or cloth.

Model VE (G) for Alpha-Pleat™ Stations

The most accurate pleating geometry in the world; We recommend that you select Model VEG unless you need to process balloons with diameters larger than 14 mm or lengths longer than 124 mm. VEG, with its smaller base plate, accommodates patented Alpha-Pleat™ stations designed especially for PTCA-sized balloon wrapping, with EDM-cut stainless steel dies that are self-guided by extremely precise bearing balls, resulting in unparalleled geometric accuracy with virtually zero wear. The J-Crimp™ compression station relies on non-contacting dies with very small die-to-die gaps.

1-14 mm 62 or 124 mm 2,3,4,5,6 Hardened Stainless Steel

Model VE (T) for Twin-Cam™ Stations

Model VET uses a larger base plate that can accommodate the larger Twin-Cam pleating and compression stations, for balloon larger the 14 mm diameter or 124 mm length. The patented Twin-Cam™ mechanism ensures reliable and consistent pleating and compression, with very small die-to-die gaps, no die-to-die wear, and, uniform temperature distribution. The VET machine base can also accommodate Alpha-Pleat™ and J-Crimp™ stations for pleating and compression.
