Publication number: 20150086292Abstract: In various examples, a set screw apparatus includes a set screw including a set screw body. An abutment extends radially outwardly from the set screw body and longitudinally separated from a threaded set screw area of a first length by an unthreaded set screw area of a second length of the set screw body. A block includes a bore. A threaded block area includes a third length, wherein the abutment inhibits movement of the set screw past the threaded block area and removal of the set screw from the bore. The third length is shorter than the second length so that an entirety of the threaded block area can be disposed within the unthreaded set screw area, such that the set screw is freely rotatable within the bore, but retained within the bore, if turned in a first direction with respect to the block.Type: ApplicationFiled: September 20, 2013Publication date: March 26, 2015Applicant: Greatbatch Ltd.Inventors: Shahn S.

Publication number: 20140005599Abstract: An implantable biomedical conductor assembly is configured for at least partial insertion in a living body. The implantable conductor assembly includes an inner tubular structure and an outer tubular structure generally surrounding the inner tubular structures such that a gap of less than about 0.030 inches exists there between. A dynamic coil is located in the gap. The dynamic coil includes a plurality of insulated conductors that are coiled generally at or below a yield point. The insulated conductors are permitted to expand within the gap to engage an inner surface of the outer tubular structure in an expanded coiled configuration. At least one mechanical restraint at each of a distal end and a proximal end retains the dynamic coil in the tubular structures. Free ends of the insulated conductors extend beyond the proximal and distal ends to facilitate attachment to electrodes and connectors.Type: ApplicationFiled: June 29, 2012Publication date: January 2, 2014Applicant: GREATBATCH LTD.Inventors: SHAHN S.
