ABSTRACT:
The present invention relates generally to a catheter having a torque transmitting shaft which retains adequate flexibility. The catheter includes an elongate shaft having an outer surface. In a preferred embodiment, a raised pattern is disposed on the outer surface. Preferably, the raised pattern improves the transmission of torque along the elongate shaft by including a series of bearing points which contact other bearing points along the shaft when torqued.
