Abstract: A radiopaque marker may include a body formed of a polymer and being adapted to be disposed around a portion of an implantable medical lead and a symbol formed of at least a radiologically dense powder or liquid added to the body and designed to identify the implantable medical lead as being safe application of a medical procedure. In some instances, the symbol may be formed of a polymer mixed with the radiologically dense powder or liquid. The body may also be formed of a polymer mixed with a radiologically dense powder or liquid wherein the mixed polymer forming the symbol is radiologically denser than the mixed polymer forming the body.

Abstract: A medical electrical lead may include a lead body having a proximal end and a distal end, a conductive electrode shaft located near the distal end within the lead body, a coiled conductor extending within the lead body from the proximal end and coupled to a first end of the conductive electrode shaft, and an electrode located near the distal end of the lead body and coupled to an opposite end of the conductive electrode shaft as the coiled conductor. The lead may also include an energy dissipating structure located near the distal end of the lead body and formed from a conductive material that defines a lumen through which a portion of the coiled conductor extends. The portion of the coiled conductor extending through the lumen defined by the energy dissipating structure is formed to provide an interference contact with the energy dissipating structure.

Abstract: This disclosure describes an implantable medical electrical lead and an ICD system utilizing the lead. The lead includes a lead body defining a proximal end and a distal portion, wherein at least a part of the distal portion of the lead body defines an undulating configuration. The lead includes a defibrillation electrode that includes a plurality of defibrillation electrode segments disposed along the undulating configuration spaced apart from one another by a distance. The lead also includes at least one electrode disposed between adjacent sections of the plurality of defibrillation sections. The at least one electrode is configured to deliver a pacing pulse to the heart and/or sense cardiac electrical activity of the heart.

Abstract: A tethering assembly for securing a medical device includes a shaft and a wire that extends in sliding engagement within a proximal lumen, a channel, and a distal receptacle of the shaft. A retainer zone of the shaft, through which the channel extends, stops a transition segment of the wire, which extends between a proximal and a distal segment of the wire, from moving into the shaft receptacle, thereby restraining a distal-most tip of the wire from moving through a distal-most opening of the receptacle. When a projecting member of the device has entered a secure zone of the receptacle, via movement through the distal-most opening and a tapering passageway thereof, the distal-most tip of the wire, which may be spring-biased, can move distally into the passageway so that the tip blocks the projecting member from moving distally, back through the passageway.
