摘要： Methods facilitate inserting a cardiac lead into a patient's vasculature. A cardiac lead system includes a cardiac lead having a lumen, and a guide member displaceable within the lumen. The guide member includes a guide wire extension that extends distal to the elongated body of the guide member. The guide wire extension is dimensioned to pass through an external distal opening of the cardiac lead lumen. Engagement of stop features or a stop mechanism of the cardiac lead system provides a push point for advancing the cardiac lead system through the patient's anatomy.

摘要： A method of manipulating a catheter assembly involves providing an inner catheter member movably disposed within an outer catheter member. At least a distal end portion of the inner catheter member has a stiffness greater than that of at least a distal end portion of the outer catheter member. The distal end portion of the outer catheter member includes a deflectable distal end. The method further involves advancing the inner catheter member through the outer catheter member toward the deflectable distal end of the outer catheter member, and longitudinally displacing the distal end portion of the inner catheter member relative to the deflectable distal end of the outer catheter member to alter a shape of the deflectable distal end.

摘要： A seal adapted for use with medical devices is provided. The medical device may be a lead having a distal tip adapted for implantation on or about the heart and for connection to a system for monitoring or stimulating cardiac activity. The lead assembly in one embodiment includes an atraumatic tip. A seal is provided within the lead tip assembly, which prevents or limits further entry of fluids through the lead tip. The lead may be a left ventricular lead with a hemostasis mechanism provided therewithin.

摘要： A lead having an atraumatic tip is adapted for implantation on or about the heart within the coronary vasculature and for connection to a signal generator. The lead is constructed and arranged so that when it is implanted, the electrodes are housed in the coronary vasculature and are biased toward a vessel wall by a preformed biased portion. Near the distal end, the lead has an optional tapered portion and a flexible portion, where the flexible portion is more flexible than the biased portion.

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。
