Ultrasound Guidance Assembly and System

A method for measuring a distance along a projected path of a pacemaker lead that is deployed from a right side of an interventricular septum of a heart to a position proximate to a left sided endocardium of the heart, the method comprising:

• a. advancing a guide wire through a subclavian vein;
• b. advancing a guide catheter over the guide wire, wherein the guide catheter comprises a catheter body having an open end;
• c. inserting a pacemaker lead into the guide catheter, the pacemaker lead comprising at least one marker disposed thereon configured to be visible under imaging, or an ultrasound transducer disposed on at least a portion of the pacemaker lead configured to detect anatomical features;
• d. advancing guide catheter and pacemaker lead through a right atrium of the heart and positioning the guide catheter and pacemaker lead adjacent to the interventricular septum of the heart;
• e. image the interventricular septum using the ultrasound transducer to identify a thickness of an interventricular septum of the heart;
• and
• f. advancing the pacemaker lead a distance into interventricular septum.

A pacemaker lead-guide catheter kit with distance, position, and thickness detection capabilities, the kit comprising:

• a. a guide catheter comprising:
• i. a catheter body having an end with an access opening formed therein and a tip having an opening formed therein, the catheter body having a bore extending along a length between the opening of the end and the tip;
• ii. at least one penetration gauge having indicia formed on a portion of the catheter body, the penetration gauge comprising a transparent material;
• iii. a hub extension having indicia on its body with a penetration gauge comprising a transparent material;
• iv. at least one ultrasound transducer disposed proximate to the tip and configured to image coaxially through the interventricular septum, wherein an image from the ultrasound transducer provides a position of the guide catheter in relation to the intraventricular septum;
• b. a pacemaker lead insertable in the bore for delivery to the left sided endocardium of the heart, the pacemaker lead comprising:
• i. an elongated body having at least one end anchorable to cardiac tissue;
• and
• ii. at least one anchor disposed on the at least one distal end of the pacemaker lead and configured to anchor the at least one distal end of the pacemaker lead proximate in the left sided endocardium of the heart.
