Abstract
During assembly of a medical electrical lead, the tubular lead component is slid over the outer surface of the lead body to a desired location on the lead. The ends of the tubular lead body are sealed and a space is defined between the inner surface of the tubular lead component and the outer surface of the lead body. Medical adhesive is injected through the port(s) to substantially fill the space between the tubular component and the lead body. The adhesive is then cured. Any ports extending away from the sleeve are removed after the curing step.
Claims16
A method of assembling a lead body comprising:
- providing a lead body having a proximal end, a distal end, and an outer surface;
- positioning a tubular lead component onto the lead body, the tubular lead component comprising a sleeve including a first end and a second end, a lumen having an inner surface extending between the first and second ends, and at least a first port and a second port located on the sleeve, wherein a space is defined between the outer surface of the lead body and the inner surface of the tubular lead component;
- circumferentially sealing the first end and the second end of the tubular component to the outer surface of the lead body;
- delivering a medical adhesive through the first port to substantially fill the space defined between the outer surface of the lead body and the inner surface of the tubular component;
- and
- curing the medical adhesive to secure the tubular component.
