Patent ID: 7507205

Claim:
A catheter, comprising: an elongated tubular member having a proximal end, a distal end and a lumen extending between the proximal end and the distal end; a plurality of electrical cables bundled together and located within the lumen of the tubular member, a cross-section of the bundle of cables being substantially ovular or rectangular so as to be selectively bendable in two approximately opposite directions; and an ultrasound transducer adjacent the distal end of the tubular member, wherein a distal end of the plurality of electrical cables are coaxial cables and a distal end of the plurality of coaxial cables is connected to the ultrasound transducer, and wherein a section of the elongated tubular member adjacent the ultrasound transducer comprises: a hollow cylinder with a proximal end and a distal end and a first aperture and a second aperture, the first and second apertures opposing each other, wherein a steering cable is threaded through the proximal end of the hollow cylinder passing through a lumen of the hollow cylinder, out the first aperture, around an outer circumference of the hollow cylinder, and through the second aperture back into the lumen of the hollow cylinder and out the proximal end; and a flexible tubular member coaxially fitted over the proximal end of the hollow cylinder.
