NEUROVASCULAR CATHETER EXTENSION SEGMENT
First Claim
1. A neurovascular catheter extension segment, comprising:
- an elongate flexible control wire, having a proximal end and a distal end;
a tubular extension segment having a side wall defining a central lumen carried by the distal end of the control wire, the side wall comprising;
a tubular inner liner;
a tie layer separated from the lumen by the inner liner;
a helical coil surrounding the tie layer; and
an outer jacket surrounding the helical coil.

Abstract
A neurovascular catheter extension segment is provided, such as for distal neurovascular access or aspiration. The neurovascular catheter extension segment includes 1) an elongate flexible control wire having a proximal end and a distal end and 2) a tubular extension segment having a side wall defining a central lumen carried by the distal end of the control wire. The side wall of the tubular extension segment includes a tubular inner liner, a tie layer separated from the lumen by the inner liner, a helical coil surrounding the tie layer, and an outer jacket surrounding the helical coil. The extension segment may be introduced into the proximal end of a neurovascular catheter and advanced distally to extend beyond the catheter and thereby extend the reach of the catheter.
