    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 fixation member disposed just proximal of its tip. The fixation member comprises a radially expandable polymeric matrix that incorporates an osmotic agent so that when placed in a aqueous medium it will swell. Thus, when placed in a cardiac vein, the swelling of the fixation member will anchor the lead against longitudinal displacement due to body motion, blood flow and the beating action of the heart.

    摘要翻译： 用于心脏装置用于植入心脏冠状静脉系统的静脉导管包括引线体，其适于通过血管系统引导到冠状窦中，将引线的远端部分放置在大心脏中 静脉或分支静脉。 引线体包括设置在其尖端附近的固定部件。 固定构件包括可渗透的聚合物基质，其包含渗透剂，使得当放置在水性介质中时，其将溶胀。 因此，当放置在心静脉中时，固定构件的肿胀将由于身体运动，血液流动和心脏的打动作用而使引线抵抗纵向移位。

    摘要： An apparatus for performing a minimally-invasive surgical procedure in the vagus nerve region includes a cannula, an endoscopic dissection tool and a cradle assembly slideably disposed in a cannula lumen. The cradle assembly includes a C-ring, an electrode cuff disposed over an exterior surface of the C-ring, and a deployment device. The electrode cuff is adapted to wrap around the target nerve region or nerve branch to be stimulated when deployed from the C-ring using the deployment device. A method of performing a minimally invasive surgical procedure is also described.

    摘要： The present invention is a myocardial lead attachment system for securing a distal end of a cardiac lead within a myocardium of a patient's heart and anchoring against an epicardium of the patient's heart. The system includes an anchor configured to advance in a first orientation and anchor against an epicardial surface in a second orientation and a tether having a proximal end and a distal end. The anchor is coupled to the distal end of the tether. The system includes a cardiac lead having a lead body, a lumen extending through the lead body, a conductive member, a proximal end, a distal end, and an electrode configured for stimulating the myocardium located at the distal end. The lead body and the lumen are configured such that the lead body can be threaded over the proximal end of the tether and slideably advanced over the tether toward the anchor during implantation. The system includes a fixation mechanism at the distal end of the cardiac lead. The fixation mechanism is adapted to collapse to a first configuration during implantation and deploy to a second configuration after implantation.
