摘要： ABSTRACT A loading device for loading a guide wire within a medical electrical lead that includes a navigation portion, having an outer portion, and extending from a front end to a back end, and having an opening formed at the back end. An engagement cavity receives and properly orientates the lead distal tip to align the lumen of the lead with the opening of the navigation portion during the loading of the guide wire within the lead. A first side wall is spaced from a second side wall to form a slot extending along the outer portion from the front end to the back end of the navigation portion, and the guide wire is advanced through the slot as the lead having the guide wire loaded therein is removed from the loading device.

摘要： Bilumen catheters and methods of using same for facilitating implantation 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 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： This is a combination method and system for intravascularly accesing and visualizing a body structure. A system is disclosed comprising a sheath, a balloon catheter, and a catheter deflection mechanism. A micro-deflection mechanism, which may be placed into the lumen of devices such as cardiac leads or electrophysiology catheters, is also provided for accurate guidance and placement of such devices to their target location. In one embodiment, a procedure for a lead or catheter placement is described in which a combination deflection mechanism, ballon catheter, and sheath assembly access the coronary sinus ostium via a superior approach. A distal balloon on the catheter is inflated and an occlusive venogram is obtained under fluoroscopic guidance to visualize the coronary veins. The sheath is advanced into the coronary sinus ostium and the balloon is deflated. The catheter and deflection mechanism are then removed. Next, a micro-deflection mechanism that has been inserted into the lumen of a cardiac lead is deployed through the sheath, allowing the lead to deflect with a high degree of accuracy and control as it is placed in the selected location.

摘要： A non-sheath based medical device delivery system is provided including an elongated tubular guide body (10) having a distal end (14) fixedly attached to a resilient collet (18) with a longitudinal opening to receive a medical lead or other device. The collet may be opened by actuating a retraction member (26) to cause the closing member (22) to slide proximally along the collet shaft, allowing the collet to maintain a normally open position. With the collet closed, the device may be advanced to a desired internal body location by advancing the guide body. The majority of the device body will be exposed, running alongside the guide body, allowing any sensors or electrodes located on the device body to be fully operational during the implantation procedure. The delivery system may be removed by opening the collet, to slidably disengage from the device body.
