摘要:
A peel away lead implant tool is adapted to be disposed over the terminal connector of a lead during an implantation procedure to protect the terminal connector. The peel-away lead implant tool includes a flexible polymer sheath including electrical contacts formed in a contact region of the sheath. The electrical contacts can be either metal foil contacts or conductive polymer contacts and extend from an outer surface to an inner surface of the sheath such that when the testing apparatus is coupled to the lead implant tool, the electrical contacts are pressed into electrical contact with the ring electrodes located on the terminal connector. The lead implant tool configured for facilitating the easy removal of the implant tool from the terminal connector when the implantation procedure is complete.

A display system and method of advertising, includes, in one embodiment, loading a graphic advertisement onto a computer-readable medium of an electronic device. The graphic advertisement is or has a time passage indicator for indicating the passage of time. An idle-time sensor determines an idle-time period in which updated application information is not presented on a display of the device due to, for example, data processing activity by the processor, data transfer activity, congestion or latency in the network, or any other activity that occupies resources in the device to delay or temporally preventing updating of the display. The graphic advertisement is displayed when the device is in the idle-time period, animated to indicate the passage of time, and removed after the idle-time period has ended.

An implantable medical lead having a modified electrode surface for imparting current density directionality within an electrode is disclosed. An implantable medical lead includes a lead body having a proximal section and a distal section having a pre-biased shape configured to secure the lead to an inner wall of a blood vessel. An electrode coupled to the distal section of the lead body includes a number of surface features on an inactive portion of the electrode that impart a current density directionality towards an active portion of the electrode that contacts the inner wall of the vessel. Methods for imparting current density directionality within an implantable lead electrode are also disclosed.

Lead electrodes having an asymmetrically distributed current density and methods for imparting current density directionality in lead electrodes are described. An implantable medical lead includes a lead body having a proximal section that connects to another implantable device and a distal section having a pre-biased shape configured to secure the lead to an inner wall of a body vessel. An electrode coupled to the distal section of the lead body includes a conductor mass having an asymmetrically distributed current density that imparts a directionality to one or more active portions of the electrode.
摘要:
A multi-lumen lead body having a smooth transition between regions of varying stiffness on the lead body is described. In one example, the different regions of the lead body can be formed by altering a mix ratio of the different polymers used to form the lead body during the extrusion process. In another example, two or more layers of polymeric materials are co-extruded, and the cross-sectional thicknesses of each of the layers varied in the different regions of the lead body to achieve different stiffnesses. In yet another example, the internal geometry of the lead body is altered during the extrusion process to alter the physical properties of the lead body in a select region of the lead body. In still yet another example, a transition member is provided between regions of varying stiffness to facilitate a smooth transition between the different regions.
