Abstract
An embodiment of an elongate medical device may comprise a shaft body having a distal end portion and a proximal end portion and three or more deflection wire assemblies, each deflection wire assembly comprising a flat wire coupled to the distal end portion and configured to deflect the distal end portion. Each flat wire may have a respective length defining a respective deflection radius, wherein each deflection radius is different.
Claims20
An elongate medical device comprising:
- a shaft body comprising a distal end portion and a proximal end portion;
- and
- three deflection wire assemblies, each deflection wire assembly coupled to said distal end portion and configured to be deflected such that said distal end portion is deflected in substantially the same direction as the deflection of each deflection wire assembly;
- wherein each deflection wire assembly is configured to be deflected such that said distal end portion deflects into a shape corresponding to each deflection wire assembly.

An elongate medical device comprising:
- a shaft body having a distal end portion and a proximal end portion;
- a first deflection wire assembly comprising a first flat wire coupled to said distal end portion, said first deflection wire assembly configured to be deflected such that said distal end portion is deflected in a direction with a first radius of deflection;
- and
- a second deflection wire assembly comprising a second flat wire coupled to said distal end portion, said second deflection wire assembly configured to be deflected such that said distal end portion is deflected substantially in said direction with a second radius of deflection;
- wherein said second radius of deflection is smaller than said first radius of deflection.
