Catheter with multi-functional control handle having linear mechanism |
摘要 |
A catheter for use in a patient's heart, especially for mapping a tubular region of the heart, has a catheter body, a deflectable intermediate section and a distal a mapping assembly that has a generally circular portion adapted to sit on or in a tubular region of the heart. A control handle of the catheter allows for single-handed manipulation of various control mechanisms that can deflect the intermediate section and contract the mapping assembly by means of a deflection control assembly and a linear control assembly. The deflection control assembly has a deflection arm and a rocker member. The linear control assembly has a linear control member, an inner rotational member and a cam. A pair of puller members are responsive to the deflection control assembly to bi-directionally deflect the intermediate section. A third puller member is responsive to the linear control assembly to contract the generally circular portion of the mapping assembly. |

1. A catheter comprising:
a catheter body; a deflectable intermediate section distal the catheter body; a mapping assembly distal the intermediate section, the mapping assembly having a generally circular portion; a control handle proximal the catheter body, the control handle having a longitudinal axis and comprising:
a deflection control assembly; anda linear control assembly having a control member, an inner rotational member, and a cam fixed against translational and rotational movement relative to the control handle, the control member adapted for linear movement along the longitudinal axis of the control handle; first and second puller members responsive to the deflection control assembly adapted to deflect the intermediate section; and a third puller member responsive to the linear control assembly adapted to contract the generally circular portion of the mapping assembly.
