Lead locking device and method

A lead locking device comprising:

• a lead engaging member having a distal end and a proximal end, said lead engaging member defining a lumen extending along a longitudinal axis between said distal end and said proximal end;
• and
• a mandrel disposed in said lumen and attached to said distal end of said lead engaging member, said mandrel extending along substantially an entire length of said lumen and protruding beyond a most proximal end of said lead engaging member,
• wherein said lead engaging member has a first configuration adapted to be inserted into a lumen of a lead and a second configuration adapted to engage said lead from within said lumen of said lead for removal of said lead,
• said lead engaging member has a maximum transverse diameter in said first configuration that is less than substantially all diameters of said lumen of said lead along substantially the entire length of said lead, and said lead engaging member has a transverse diameter in said second configuration that is at least substantially equal to diameters of said lumen of said lead along substantially the entire length of said lead, and
• wherein said lead engaging member is a sheath of elastic material.

• wherein said lead engaging member is a braided sheath.

A medical device, comprising:

• a surgically implantable electrical lead defining a lumen therein;
• and
• a lead locking device, comprising:
• a lead engaging member having a distal end and a proximal end, said lead engaging member defining a lumen extending along a longitudinal axis between said distal end and said proximal end;
• and
• a mandrel disposed in said lumen of said lead engaging member and attached to said distal end of said lead engaging member, said mandrel extending along substantially the entire length of said lumen of said lead engaging member and protruding beyond the proximal end of said lead engaging member,
• wherein said lead engaging member has a first configuration adapted to be inserted into said lumen of said lead and a second configuration adapted to engage said lead from within said lumen of said lead, and
• wherein said lead engaging member is adapted to engage said lead along at least about 30% of the entire longitudinal length of said lumen of said lead for removal of said lead.
