Abstract
A medical electrical lead includes a lead body and a connector terminal. A conductor extends from the lead body to the connector terminal along a helical path through a transition zone.
Claims43
A medical electrical lead, comprising:
- a lead body;
- a connector terminal coupled to the lead body;
- a lead body-to-connector transition zone comprising a first multi-lumen tube including a proximal end, a distal end, a central lumen extending from the proximal end to the distal end and a peripheral lumen extending from the proximal end to the distal end in a helical path about the central lumen;
- and
- a conductor extending from the lead body to the connector terminal through the peripheral lumen of the first multi-lumen tube.
2 more elements
A method for assembling a transition zone between a medical electrical lead body and a lead connector assembly, the method comprising the steps of:
- forming a multi-lumen tube having a peripheral lumen extending from a first end to a second end of the tube in a helical path about a central lumen of the tube;
- positioning the multi-lumen tube adjacent the connector assembly;
- and
- positioning a medical electrical lead conductor within the peripheral lumen.

A medical electrical lead, comprising:
- a lead body;
- a connector terminal coupled to the lead body;
- a lead body-to-connector transition zone extending between the lead body and the connector terminal;
- and
- a conductor extending from the lead body to the connector terminal through the transition zone in a helical path, the helical path including a distal part having a first pitch and a proximal part having a second pitch, the second pitch being greater than the first pitch.
