Image guidance of a steerable introducer for minimally invasive procedures

摘要

A steerable introduction system for deploying an interventional tool (e.g., a replacement valve) within an anatomical object (e.g. a heart). The steerable introduction system employs a steerable introducer (20) including an end-effector for positioning the interventional tool within the anatomical object (e.g., the end-effector passively guides or actively steers the interventional tool within the anatomical object). The steerable introduction system further employs an image guidance workstation (120) controlling an actuation of a translation, a pivoting and/or a rotation of the end-effector within the anatomical object responsive to surgical image data illustrative of a position of the end-effector within the anatomical object (e.g., ultrasound or X-ray image data illustrative of a surgical position of the end-effector within a heart). The motion actuation by the image guidance workstation (120) of the end-effector facilitates a coaxial alignment and/or a coplanar alignment of the interventional tool and a structure of the anatomical object (e.g., a diseased aortic valve of a heart).
