Figure 3. Location and number of tendons in the tendon-drive catheters. (a) The catheter is driven by one tendon and examples can be found in [Citation5,Citation35–37]; (b) The catheter is driven by a pair of tendons which are placed in 180° and examples can be found in [Citation15,Citation38,Citation39]; (c) The catheter is driven by three tendons placed 120° apart and examples can be found in [Citation40,Citation41]; (d) The catheter is driven by four orthogonally spaced tendons and examples can be found in [Citation16,Citation42,Citation43].
