Catheter pull wire actuation mechanism
First Claim
1. A catheter comprising:
- an elongate shaft component extending between a proximal end and a distal end thereof;
an elongate pull wire extending within the shaft and having a proximal end and a distal end, wherein the distal end of the pull wire is secured to an actuatable component; and
an actuation mechanism disposed on a proximal portion of the shaft component with the proximal end of the pull wire being coupled thereto, wherein the actuation mechanism has a first housing portion and a second housing portion that are longitudinally translatable relative to each other and to the shaft component such that longitudinal translation of the first housing portion in a first direction relative to the shaft component with a corresponding longitudinal translation of the second housing portion in an opposite, second direction relative to the shaft component actuates the pull wire.

Abstract
A catheter has an elongate tubular component that defines a pull wire lumen, which extends along at least a portion of a length thereof. A pull wire extends within the pull wire lumen with a distal end of the pull wire being secured near a distal end of the catheter. The catheter includes a pull wire actuation mechanism slidably disposed thereon that is operably coupled to a proximal end of the pull wire. The pull wire actuation mechanism includes a first or upper housing portion that is longitudinally translatable in a first direction relative to the guide catheter and a second or lower housing portion that is longitudinally translatable in an opposite, second direction relative to the catheter to actuate the pull wire and selectively operate the distal end thereof.

11. A guide catheter comprising:
-
an elongate tubular component defining a central lumen from a proximal end to a distal end thereof and defining a pull wire lumen along at least a portion of a length thereof; a pull wire extending within the pull wire lumen of the tubular component, wherein a distal end of the pull wire is secured to the distal end of the tubular component; and a pull wire actuation mechanism slidably disposed on the tubular component and operably coupled to a proximal end of the pull wire, wherein the pull wire actuation mechanism has an upper housing that is longitudinally translatable in a first direction relative to the tubular component and a lower housing that is longitudinally translatable in an opposite, second direction relative to the tubular component to actuate the pull wire to selectively deflect the distal end of the tubular component. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
