The "Skipping Rope" Technique: A Novel Strategy for Distal Burr Entrapment During Rotational Atherectomy. [PDF]
Catheter Cardiovasc IntervABSTRACT We describe the “skipping rope technique” for managing burr entrapment during rotational atherectomy. Sequential counterclockwise rotational force is applied to the drive shaft, generating alternative torque dynamics. This maneuver provides a safe method to disengage a stuck rotaburr, offering operators an additional strategy for this ...

An impedance approach to reduce the contact-instability whilst drilling with active heave compensation [PDF]
, 2012 The bit-bounce, or contact-instability, phenomenon which occurs in the drill string suspended from a floating vessel with an active drill string compensator to maintain a steady weight on the drill bit is investigated.
