First Claim
Patent Images
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.

22. A system for guiding the advancement of a device within the body of a patient comprising:
-
(a) a guide structure dimensioned to allow advancement of the device into the body, the guide structure comprising a distal exit portion oriented to an angle between zero and 180 degrees relative to an axis of the guide structure and a proximal portion having a radially nonuniform feature oriented in a fixed relationship with respect to the angle of distal exit portion; (b) an adapter device capable of releasably attaching to the guide structure, wherein the adapter device comprises an engagement element, wherein the engagement element defines an aperture; (c) a navigation element confined within the engagement element of the adapter device, wherein the navigation element is capable of being detected by a computer-based navigation system, the navigation element housed within the aperture of the engagement element during use; and (d) a medical device positioned in the guide structure and advanceable along the guide structure. - View Dependent Claims (23, 24, 25, 26, 27)
