Abstract
Abstract A guide, and methods for its manufacture and use, for use with a medical instrument whereby the instrument must contact a patient's tissue at a particular location. Given the specific patient's tissue geometry, the general medical procedure and the specific practitioner's requests, if any, a nonadjustable guide is specifically manufactured such that one or more locations of the invention attaches to and/or abuts against a portion of patient tissue correctly orienting the device with respect to the patient's tissue geometry for purposes of performing the given medical task. The remaining geometric features of the device are dictated by the task for which it is designed and other characteristics of the tissue.
