Junkosha, a provider of peelable heat shrink tubing (PHST) technology, offers ultra-small, high-shrink ratio PHST, delivering a solution for accessing to the most exacting parts of the vasculature with minimal impact on the patient. Suitable as tubing for laminating jacket coating in tiny guide wires, 0.011" and 0.014", PHST has a recovered ID as low as 0.009". Miniature guide wires navigate vessels to reach a lesion or vessel segment within the brain or heart. The high-shrink ratio PHST (2:1) supports processes where tapered microcatheter shafts are used or where tolerance take-up is an issue.

“Our aim is to answer customers’ unmet needs through technology innovation. As a part of this, we are being asked for solutions that take small to the next level,” says Joe Rowan, president and CEO of USA and Europe, Junkosha.

Polycarbonate for better performing IV connectors

Makrolon Rx3440, a medical polycarbonate from Covestro LLC, offers durability and chemical resistance to prevent cracking for safer delivery of oncology drugs, and demonstrates retention of stress to provide more reliable IV connections.

Advantages include:
  • Biocompatible to ISO 10993-1, USP Class IV standards
  • Greater structural integrity for thin-walled designs
  • Toughness to resist mishandling
  • Dimensional stability in shipping, storage

Piezo-mechanic nanopositioning motion systems

PI’s (Physik Instrumente) 250-page catalog on precision mechatronic actuators and nanopositioning systems based on piezo drive technology and frictionless flexure guiding systems is now available. Electro-ceramic piezo actuators deliver a combination of precision, speed, and force in a small package. A lack of friction, particle generation, and associated wear makes the actuators suited for high-tech applications. Miniaturized systems are available for easy integration into new or existing industrial, research, and original equipment manufacturer (OEM) systems.

Products covered range from low-cost OEM-type flexure actuators to 6-axis integrated nanopositioning systems, ultra-fast laser steering systems, and photonics alignment systems. Along with the piezo mechanic systems, digital controllers and sub-nanometer precise position sensors are part of the solutions available.

Rotary ball spline, precise robotic movement

There is a lot of torque on a robotic arm, and a ball spline’s specialty is torque transfer. Using NB Corp. of America’s rotary ball splines allows robotic arm customization, so cabling can run the length of an arm by using a hollow shaft ball spline. The NB rotary ball spline has a nut that rolls on the ball spline shaft, making it capable of linear and rotary motion, providing sub-millimeter accuracy. For greater load rating without increasing the size of the machine, users can specify a ball spline with cross rollers as opposed to balls in the rotary motion.
