摘要： A medical electrical lead and methods of implanting medical electrical leads in lumens. Leads in accordance with the invention employ preformed biases to stabilize the lead within a lumen or lumen and to provide feedback to lead implanters. In some embodiments, a preformed bend in the lead may assist an implanter with orienting the lead within a lumen.

摘要： A catheter assembly for cannulating an ostium of a coronary sinus of a heart comprises an outer catheter member and an inner catheter member. The outer catheter member has a distal end portion including a deflectable distal end and a lumen extending through the deflectable distal end, wherein the distal end portion includes regions of varying stiffness and has a pre-formed curvature. The inner catheter member is slidably and rotatably disposed within the lumen of the outer catheter member, and has a distal end portion including a distal end, and a lumen extending through the distal end. The distal end portion of the inner catheter member has regions of varying stiffness and a pre-formed curvature. The outer and inner catheter members are configured such that relative translation and rotation of the outer and inner catheter members causes the distal end of the outer catheter member to assume a plurality of two and three dimensional shapes.

摘要： A lead for navigating small vessels and a catheter system for implantation of leads into small vessels. Veins that return blood to the heart against the force of gravity often have valves in them to prevent backflow of deoxygenated blood. Leads and catheter systems in accordance with embodiments of the invention allow cannulation and lead implantation in small, tortuous, obstructed, and difficult to access veins enabling a range of stimulation and sensing applications.

摘要： Apparatus and surgical methods establish temporary suction attachment to a target site on the surface of a beating heart for analyzing electrical signals or hemodynamic responses to applied signals at the target sites for enhancing the accuracy of placement of cardiac electrodes at selected sites and for enhancing accurate placement of a surgical instrument maintained in alignment with the suction attachment. A suction port on the distal end of a supporting cannula carries surface-contacting electrodes and provides suction attachment to facilitate temporary positioning of the electrodes in contact with tissue at the target site, and a clamping and release mechanism to facilitate anchoring a cardiac electrode on the moving surface of a beating heart at a selected site. Analyses of sensed signals or responses to applied signals at target sites promote epicardial mapping of a patient's heart for determining optimum sites at which to attach cardiac electrodes.

摘要： An improved guidewire for assisting in implantation of a cardiac lead includes three sections. The most distal zone is sufficiently floppy to prevent trauma to the vessel walls through which the guidewire and lead are inserted. An intermediate zone is generally stiffer and has a cross-section less than or equal to the cross-section of the distal zone. The third zone is stiffer yet and is joined to the intermediate zone by a shoulder. The shoulder cooperates with protrusions on the lead to transfer forces between the guidewire and lead. A finishing wire having temporary locking means to lock the finishing wire to the lead is employed to remove the guide catheter without moving the lead from its desired location. Lubricious coatings are also provided to reduce friction between the lead and guidewire.

摘要： An apparatus for fixing a cardiac lead in place within the vasculature of the heart includes a coil having a normal helical shape and a stylet for holding the coil straight during insertion of the coil through a lumen of the lead. Upon retraction of the stylet, the coil returns to its helical shape along with the lead, forcing portions of the lead into contact with the vessel wall.

摘要： An intravenous lead for use with a cardiac device for implantation in the coronary venous system of the heart includes a lead body that is adapted to be routed through the vascular system into the coronary sinus with the distal end portion of the lead placed in the great cardiac vein or branch vein. The lead body includes a preformed section disposed just proximal of its tip so that the lead body exhibits a two-dimensional wave having peaks and valleys for contacting the endothelial layer of the vein at discrete, longitudinally spaced points to stabilize the electrode against displacement.
