TELESCOPING NEUROVASCULAR CATHETER WITH ACTIVE DISTAL TIP
First Claim
1. A telescoping catheter, comprising:
- an elongate, flexible tubular body, comprising a proximal section having at least one lumen and a distal section axially movably positioned within the lumen; and
a control for advancing the distal section from a first, proximally retracted position within the proximal section to a second, extended position, extending distally beyond the proximal section; and
an active tip on the distal end of the distal section, comprising a distal opening that is movable between a smaller and a larger configuration.

Abstract
A telescoping catheter is provided such as for distal neurovascular aspiration or access. The catheter includes an elongate, flexible tubular body, having a proximal section with at least one lumen and a distal section which is axially movably positioned within the lumen. A control is provided for advancing the distal section from a first, proximally retracted position within the proximal section to a second extended position, extending distally beyond the proximal section. The distal end of at least one of the proximal and distal sections may be provided with at least one active feature, such as at least one movable jaw or rotatable agitator, to assist in the capture of vascular obstruction. The jaw may be operable in response to application of pulsatile negative pressure through the catheter.
