    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.

    摘要: Elongated medical devices are disclosed adapted to be inserted through an access pathway into a body vessel, organ or cavity to locate a therapeutic or diagnostic distal segment of the elongated medical device into alignment with an anatomic feature of interest. Multi-lumen steerable catheters having a deflection lumen liner and a delivery lumen liner are adapted to be deflected by a deflection mechanism within or advanced through the deflection lumen liner to enable advancement of the catheter distal end through a tortuous pathway. At least one lumen liner is formed of a no yield elastomer.

    摘要: A splined multilumen body for use in elongated medical devices is provided for carrying multiple conductors, wires or cables to multiple device components along the device body. Open lumens may be provided through which medical devices or therapies may be delivered. The multilumen body is constructed from a generally tubular outer member having inward-radiating splines that mate with outward-radiating splines on a generally tubular inner member. Lumens formed between sets of mated splines isolate conductors carried therein. Interaction of mated splines provides good torque transfer between outer and inner members. Materials for fabricating outer and inner members may be selected to achieve desired torque transfer properties, flexibility, and surface friction.
