Abstract:
1. A deflectable catheter assembly comprising: a catheter shaft having a catheter proximal section and a catheter distal section, the catheter distal section defining a length, said catheter distal section being more flexible than said catheter proximal section and said catheter proximal section having a length greater than that of the catheter distal section; a tendon disposed within a first lumen of said catheter shaft, said tendon being approximately centrally located within said catheter shaft along an entire length of said catheter proximal section and said first lumen located off-center of said catheter shaft at said catheter distal section, wherein deflection of the tendon deflects said catheter distal section without modifying the catheter distal section length; a needle disposed within a second lumen of said catheter shaft, said second lumen being located off-center within said catheter shaft at said catheter proximal section and said second lumen approximately centrally located within said catheter shaft at said catheter distal section; and a catheter handle coupled to said catheter shaft, said catheter handle including a first control mechanism to control said tendon.
