GUIDE ASSEMBLY

摘要

A guide assembly for directing a medical instrument to a desired location in a patient is provided. The guide assembly comprises an arcuate guide support having a constant radius of curvature. The guide assembly further includes an introducer and at least one probe spaced from the introducer along the guide support. The longitudinal axes of the introducer and the probe intersect at a target location within the patient. The probes can be invasive or non-invasive. The probe can be a cannula or a device that emits a therapeutic beam. More than one beam-emitting device mounted to the guide assembly can be employed concurrently or sequentially, as desired.
