Implant tool for cardiac leads

A tool for implanting a medical lead, the tool comprising:

• a body having a distal region including a distal end, a proximal region including a proximal end, a central axis extending from the distal end to the proximal end, and a midpoint between the distal end and the proximal end;
• the distal region including a rounded tip, and a distal lip surrounding a distal opening leading to a distal cavity dimensioned to receive and frictionally engage a connector component of the implantable lead;
• the proximal region including a proximal lip surrounding a proximal opening leading to a proximal cavity;
• a chamber located between the distal cavity and the proximal cavity;
• a first window and a second window that each reduce in cross-section towards the central axis, wherein the second window is located opposite of the first window, and the first window and the second window allow for viewing of the chamber or movement of the pair of resilient arms;
• and
• a pair of resilient arms defining at least a portion of the chamber and configured to frictionally engage a terminal pin of the implantable lead;
• wherein the first window, second window, chamber, and pair of resilient arms are located distal of the midpoint.

• the proximal region including a proximal lip surrounding a proximal opening leading to a proximal cavity;
• a chamber located between the distal cavity and the proximal cavity, wherein the chamber includes an opening and a shoulder, and the chamber tapers from the opening towards the shoulder;
• a first window;
• and
• a pair of resilient arms defining at least a portion of the chamber and configured to frictionally engage a terminal pin of the implantable lead;
• wherein the first window, chamber, and pair of resilient arms are located distal of the midpoint, and the distal opening has a diameter smaller than the proximal opening.
