    摘要: A catheter for delivering a medical electrical lead to a bundle of His from within a right atrium of a heart. The catheter includes a straight portion and a hook portion projecting from a distal end of the straight portion. The hook portion includes a first curved portion, a second curved portion, and a third curved portion. The straight portion and the first curved portion define a plane. The second curved portion extends from a distal end of the first curved portion. The second curved portion curves away from the plane. The third curved portion extends from a distal end of the second curved portion. The third curved portion curves toward the plane. The catheter forms a lumen extending from a proximal end of the straight portion to an opening at a distal end of the third curved portion.

    摘要: A medical device lead includes a tubular conductive element disposed over a lead body. The tubular conductive element includes at least one segment having one or more kerfs formed radially therethrough in a predetermined configuration so as to affect at least one electrical property, e.g., electrical impedance, of the segment. The segment may form a shocking conductor of the medical device lead. The tubular conductive element may alternatively include proximal, intermediate and distal segments each having one or more kerfs formed radially therethrough, where the one or more kerfs in each of the proximal and intermediate segments are configured so that these segments each have a higher electrical impedance than the distal segment. A layer of insulative material is disposed over the proximal and intermediate segments, so that the proximal and intermediate segments of the tubular conductive element are operable to filter electromagnetic energy from an external source.

    摘要: A device for the active fixation of an implantable medical lead includes a housing, a tine assembly, and rotatable shaft. The housing includes a proximal end for connecting to the lead and a distal end opposite the proximal end. The housing defines a housing lumen having a longitudinal axis extending between the proximal end and the distal end. The tine assembly is disposed within the housing lumen. The tine assembly includes at least one tine configured to self-bias from a linear configuration within the housing to a curved configuration outside of the housing. The rotatable shaft extends through the housing lumen. The shaft is configured to engage the tine assembly such that rotation of the shaft transitions the at least one tine between the linear configuration and the curved configuration.
