Blockwise is an industry leader in balloon wrapping (balloon folding) equipment. These machines pleat a balloon to form a number of “wings”, and wrap the wings around the catheter shaft. The machines comprise 3 parts:

  • The pleating station divides the balloon into a number of wings spiraled around the central shaft
  • The compression station tightly compresses the winged balloon
  • The machine base controls the process.

The pleating and compression dies are temperature-controlled. The differences between the models VE, VC, and VS are not in process quality, but rather in convenience, productivity, and mistake-proofing.

Blockwise balloon wrappers (balloon folders) have heated dies, and the VE and VC machines feature full process control with recipes. Learn more about balloon wrapping basics.

Recipe-Controlled Electric Actuation Balloon Wrappers

Reliable microcontroller, with touch-screen user interface provides automatic sequencing and timing, and selectable process recipes. Electric actuation puts all process settings under recipe control, adding the final level of productivity and mistake-proofing on these catheter balloon wrapping (balloon folding) machines.

Simple Balloon Wrappers

In R&D settings and low-production settings, manual control can provide high-quality balloon wrapping. Uses the same pleating and compression stations as Model VC, but lacks computerized control and timing. Process steps are timed by the operator with a stopwatch. Station actuation and balloon inflation are are controlled through hand-operated toggle valves. Temperature control is provided.

VS with Alpha-Pleat™

Small (Including PTCA)

Diameter Length Number of Wings
0-14 mm 62 or 124 mm 2-6

VS with Twin-Cam™

Long or Large-Diameter

Diameter Length Number of Wings
0-30 mm 62-310 mm 2-8
