Abstract
A lead having a capture member for releasably engaging the enlarged distal tip of a stylet. The capture member is connected to the flexible tubular casing of the lead near the distal end and includes an aperture having a necked down portion and a socket portion. The socket portion is shaped to accomodate the enlarged distal tip of the styler. As the stylet is advanced towards the distal end of the lead the enlarged tip enters the necked down portion and is directed towards the socket portion until it pops into and is engaged within the socket portion. Once engaged the lead can be advanced, partially withdrawn, or turned by manipulating the stylet handle.
