Telemark microcatheter

Dr. José R. Rumoroso


New on the market is a microcatheter bearing the Medtronic stamp (USA). Medtronic, in collaboration with Surmodics Inc. (USA), has released a microcatheter that aspires to become the standard for multiuse microcatheters in percutaneous coronary intervention. Surmodics is a company specialized in the production of hydrophilic coatings that has been collaborating with Medronic for many years on a mission to improve the performance of their devices.

The Telemark microcatheter has three key features:

  • It is made of a mixed (flat and round) braided mesh with Xtreme technology, which provides improved push force transmission.
  • It has a Pristyne hydrophilic coating, which improves deliverability and lesion crossing.
  • It has a very low-profile, tapered design, from 2.6 to 1.4 French.

The crossability, deliverability, and lubricity of this microcatheter are significantly superior to that of other standard microcatheters on the market. Use of this Telemark device will soon become established in everyday clinical practice.
