    摘要： A method of locating a target site for delivering a therapy to a patient that includes advancing a delivery device having a steerable portion and a deflectable tip having a tapered portion to an area along a first site. A contrast media is delivered through a thru lumen and outward from a distal end of the delivery device in fluid communication with the thru lumen to position the contrast media along the first site and the delivery device is further advanced toward the first site and within the first site, or the delivery device is further advanced toward the first site and within the first site without the contrast. The contrast media is then delivered from the distal end of the delivery device within the first site to locate the target site.

    摘要： Bilumen catheters and methods of using same for facilitating implantation of cardiac leads for applying electrical stimulation to and/or sensing electrical activity of the heart through one or more electrode positioned at an implantation site within a heart chamber or cardiac vessel adjacent a heart chamber, and more particularly to a method and apparatus for introducing such a cardiac lead having low torqueability and pushability through a tortuous pathway to enable attachment of the cardiac lead at the implantation site employing a bilumen guide catheter are disclosed. The bilumen catheter body includes a relatively large diameter delivery lumen to introduce a small diameter cardiac lead and a small diameter guide lumen to receive a stylet or guidewire to locate the guide catheter body distal end at the implantation site. The small diameter lumen within a small diameter guide tube extends distally from the delivery exit port of the delivery lumen.
