Implantable lead with improved stylet lumen

An implantable lead for a medical device with an improved stylet lumen reduces the potential for damage to a stylet and seals the lead proximal end. The implantable lead comprises a lead body having a distal end and a proximal end, a stylet lumen, at least two conductor lumens, at least two conducto...

Zusammenfassung:	An implantable lead for a medical device with an improved stylet lumen reduces the potential for damage to a stylet and seals the lead proximal end. The implantable lead comprises a lead body having a distal end and a proximal end, a stylet lumen, at least two conductor lumens, at least two conductors, at least two contacts carried on the proximal end, at least two contacts carried on the distal end, and a proximal flare formed on the lead proximal end. The two conductors are contained in the conductor lumens and extend from the lead proximal end to the distal end. The two contacts carried on the lead distal end are electrically connected to the conductors. The proximal flare has tapering walls that narrow toward a stylet opening to guide insertion of a stylet into the stylet lumen, and the proximal flare seals the conductor lumens proximal end to isolate the conductor lumens.
