Bal Seal Engineering, Inc.

Simply a Better Solution

Medical Contacts

When manufacturers of active implantables need low-force, low-resistance contact solutions they can be confident about, they turn to us. For more than 20 years our electrical contact technology – based on the simple, robust Bal Seal Canted Coil Spring®, has been making and maintaining reliable connections in pacemakers, defibrillators, neurostimulators and many other critical electronic devices used to deliver life-improving therapies to the human body.

Bal Conn electrical contacts

Already at work in more than 1 million implantable devices worldwide, the Bal Conn electrical contact remains the stand-alone solution of choice for OEMs seeking to ensure consistent, reliable connections in implantable pulse generation devices used for neuromodulation and cardiac healthcare. For over two decades, the Bal Conn has been helping manufacturers improve device performance and push the technology envelope. It has also dramatically simplified the process surgeons use to connect lead wires to implantable electronic units across the therapy spectrum.

Features

Typical Applications
  • Very low electrical resistance
  • Cardiac defibrillation
  • Redundant contact point for reliable connectivity
  • Cardiac pacing
  • Excellent resistance to fatigue
  • Cardiac resynchronization
  • Better design flexibility than any other IPG interconnect technology

 

SYGNUS Implantable Contact System

SYGNUS is the world’s first integrated seal and electrical contact system for active implantable devices. It is engineered to help large and small device OEMs accelerate the development process and dedicate valuable resources to therapy and function improvements, instead of component procurement and testing.

This innovative system combines proven electrical contact technology with pre-tested silicone seals, resulting in a densely-spaced connector “stack” that can accommodate leads with diameters ranging from 0.90mm to 3.20mm. The system’s contact element consists of a housing made from medical-grade MP35N® and a Platinum-Iridium or MP35N® Canted Coil Spring. The spring contact offers low insertion force, provides multi-point conductivity, and compensates for both misalignment and mating surface irregularities.

Features

Typical Applications
  • Proven technology – SYGNUS has its origins in the trusted, reliable Bal Conn
  • Cardiac resynchronization
  • Compact design (pitch of about 2mm is smallest in the industry)
  • Cardiac defibrillation
  • Integrated – combines electrical contacts and fluid/electrical isolation components
  • Spinal cord stimulation (SCS)
  • Configurable – provides options for standard sizes in variable stack arrays
  • Deep brain stimulation (DBS)
  • Functional electrical stimulation (FES)
