INTERVENTIONAL MEDICAL SYSTEMS AND CATHETERS |
摘要 |
An interventional medical system includes an elongate shaft, a steering assembly coupled to the shaft, a snare member, and a passageway configured to allow passage of the snare member therethrough and into a first longitudinally extending lumen of the shaft; wherein the passageway is spaced distally from the steering assembly actuator by no more than 3 cm to 3.5 cm, and the passageway includes an elastic sealing perimeter. The passageway may, in some cases, be formed in a tapered member of the steering assembly that couples a proximal end of the shaft to a core of the steering assembly. |

1. An interventional medical system comprising an elongate shaft, a steering assembly coupled to the shaft, a snare member, and a passageway configured to allow passage of the snare member therethrough and into a first longitudinally extending lumen of the shaft, the steering assembly including an actuator mounted in proximity to a proximal end of the shaft, an elongate pull wire extending distally from the actuator, within either the first lumen or a second longitudinally extending lumen of the shaft, and a pull band being coupled to a distal end of the shaft and to the pull wire; and wherein an improvement to the system comprises:
the passageway being spaced distally from the steering assembly actuator by no more than approximately 3 to 3.5 centimeters; and the passageway including an elastic sealing perimeter. |
