    摘要： An epicardial patch includes an extracellular matrix (ECM) and a plurality of electrodes. The isolated ECM is configured for epicardial attachment over a myocardial region including an injured area to control post-injury remodeling of the myocardial region. The plurality of electrodes is configured for delivering electrical stimulation to enhance the effect of the isolated ECM in remodeling control by altering workload and stress on the myocardial region.

    摘要： The present invention is a myocardial lead attachment system for securing a lead within the myocardium. The attachment system includes an anchor configured to engage the heart, a tether coupled to the anchor and a lead body. The lead body has a proximal end, a distal end, a lumen for accepting the tether and a lock housing in the lumen. A lock structure is on the tether and mates with the lock housing and restrains motion of the lead with respect to the tether in either of a proximal or a distal direction.

    摘要： A technique for accessing a pericardial space of a heart includes attaching a grip to a pericardium with adhesive, grasping the grip, drawing the pericardium away from the heart, and perforating the pericardium. The grip may consist solely of an adhesive. In other embodiments, other structures for the grip are used, including anchors, suture loops, and gripping tubes.

    摘要： A seal adapted for use with medical devices is provided with a lead having a distal tip electrode. The distal tip of the lead is adapted for implantation on or about the heart and for connection to a system for monitoring or stimulating cardiac activity. The lead can include a fixation helix for securing the electrode to cardiac tissue. The lead assembly can alternatively include an open lumen lead tip. A seal is provided within the lead tip assembly such that the seal is expanded to prevent or limit further entry of fluids through the lead tip. The seal includes an expandable matrix, such as a hydrogel. The seal is formed on or within the lead when the lead and the seal comes into contact with a fluid and expands. The seal is also formed as a plug which is deployed through the medical device, and expands as the plug absorbs fluid. A housing incorporating the seal can also be attached to a portion of the medical device to provide the seal.

    摘要翻译： 适于与医疗装置一起使用的密封件设置有具有远端尖端电极的引线。 引线的远端适于植入在心脏上或其周围，并用于连接到用于监测或刺激心脏活动的系统。 引线可以包括用于将电极固定到心脏组织的固定螺旋。 导线组件可以替代地包括开放的管腔引线端头。 在引线端头组件内设置密封件，使得密封件被膨胀以防止或限制流体进一步通过引线头进入。 密封件包括可膨胀基质，例如水凝胶。 当铅和密封件与流体接触并膨胀时，密封件形成在引线上或内部。 密封件还形成为通过医疗装置展开的塞子，并且当塞子吸收流体时膨胀。 结合密封件的壳体也可以附接到医疗装置的一部分以提供密封。
