Adapter for attaching electromagnetic image guidance components to a medical device

摘要

Devices and methods wherein an adapter is used to attach an electromagnetic image guidance component to a medical device such that an electromagnetic image guidance system may be used to track the location of the medical device within the body of a human or animal subject.

主权项

1. An adapter device useable for attaching an electromagnetic image guidance element to a medical device, a distal portion of said medical device being insertable into the body of a human or animal subject during performance of the procedure and a proximal portion of said medical device remaining outside of the subject's body during performance of that procedure, said adapter device comprising:
(a) a body portion; (b) a medical device holding portion having a longitudinal axis, wherein the medical device holding portion is configured to firmly hold the proximal portion of the medical device relative to the longitudinal axis, wherein the medical device holding portion defines a longitudinal plane which extends along the longitudinal axis, wherein the medical device holding portion includes a fixed channel member unitarily coupled to the body portion; and (c) an element holding portion comprising:
(i) a distal end,(ii) a proximal end, and(iii) an engagement element coupled to the body, wherein the engagement element is partially located between the distal end of the element holding portion and the proximal end of the element holding portion;wherein the engagement element is configured to directly hold the image guidance element firmly in a substantially fixed spatial relation to at least one location of the medical device while allowing a portion of the medical device to be inserted into the subject's body for purposes of the procedure.
