Abstract
A cardiac stimulator lead is provided. The cardiac stimulator lead includes a connector for connecting to a cardiac stimulator and a flexible tubular sleeve that has a first end coupled to the connector and a second end. An electrode has a proximal end that is inserted into the second end of the sleeve. An annular member is disposed around the proximal end and the second end and is deformed to clamp the second end to the proximal end. A conductor wire is coupled between the connector and the electrode. The deformed annular member eliminates reliance on an adhesive-to-metal molecular bond as the sole or primary mechanism for securing the distal end of a lead sleeve to the tip electrode. Manufacturing and assembly time may be significantly reduced.
Claims25
A cardiac stimulator lead, comprising:
- a connector for connecting to a cardiac stimulator;
- a flexible tubular sleeve having a first end coupled to the connector and a second end;
- an electrode having a proximal end inserted into the second end;
- an annular member disposed around the proximal end and the second end and being deformed to clamp the second end to the proximal end, the annular member being composed of a radiopaque material;
- and
- a conductor wire coupled between the connector and the electrode.
A cardiac stimulator lead, comprising:
- a connector for connecting to a cardiac stimulator;
- a flexible tubular sleeve having a first end coupled to the connector and a second end;
- an electrode having a proximal end inserted into the second end, the proximal end having a plurality of grooves formed on the exterior thereof;
- an annular member disposed around the proximal end and the second end and being deformed to clamp the second end to the proximal end, and to deform portions of the sleeve into the grooves;
- and
- a conductor wire coupled between the connector and the electrode.
An assembly comprising:
- a flexible tubular insulative outer sleeve;
- an electrode having a proximal end for insertion into the sleeve;
- an annular member adapted to be positioned around the sleeve and the proximal end and deformed to clamp the sleeve to the proximal end, and
- a medical adhesive forming a molecular bond with said sleeve near said second end and a predominately mechanical bond with said proximal end of said electrode.
