    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： An apparatus includes a lead body extending from a proximal end to a distal end and having an intermediate portion therebetween. The lead body includes two or more individually insulated conductors, where a first conductor traverses along less than an entire length of the lead body and a second conductor traverses from the proximal end to the distal end of the lead body. Optionally, the first conductor has a different material than the second conductor, for instance having differing electrical properties and/or differing stiffnesses. A method includes varying the stiffness of a coiled conductor assembly including winding a plurality of conductors to form the coiled conductor assembly, and pulling at least one loop of a first conductor away from the coiled conductor assembly.

    摘要： A cardiac lead designed for implantation in the vasculature of the left side of the heart comprising a flexible lead body having a central lumen, a removable terminal pin, electrodes electrically coupled to the removable terminal pin, a mechanism for securing the electrodes in the proper position in the vasculature and a mechanism for sealing the central lumen after implantation to prevent body fluids from invading the lumen. The cardiac lead can be implanted or explanted using either a guidewire, a guide catheter or both.
