Stent delivery handle
First Claim
1. An apparatus for treating a remote location within a body lumen of a patient, comprising:
- a handle member having proximal and distal ends and proximal and distal portions defining a longitudinal axis therebetween, and a lumen therein extending between the proximal and distal ends;
a control member comprising a tubular portion aligned with the lumen of the handle member and a control portion slidably coupled to received on the distal portion of the handle member, the control portion being directable axially with respect to the handle member between distal and proximal positions;
a tubular outer member extending distally from the tubular portion of the control member;
an elongate inner member extending through the lumen in the handle member and through the tubular portion of the control member into the outer member, the inner member being substantially secured axially with respect to the handle member;
a rail extending axially along the distal portion of the handle member; and
a guide member on the control member engaging the rail for preventing rotation of the control member relative to the handle member about the longitudinal axis.

Abstract
A handle device for a catheter-sheath assembly includes a handle member having proximal and distal ends, and a control member including a tubular portion coupled to a control portion, the control portion slidably coupled to the handle member. A cooperating rail and wheel are provided on the handle member and the control portion for directing the control portion axially with respect to the handle member upon rotation of the wheel. A tubular sheath extends distally from the tubular portion, and a catheter or bumper is secured to the handle member that extends through the tubular portion into the sheath. The control portion is directable between distal and proximal positions to direct the tubular portion proximally and consequently retract the sheath with respect to the catheter or bumper to deploy a stent or other element from within the sheath.

20. An apparatus for treating a remote location within a body lumen of a patient, comprising:
-
a handle member having proximal and distal ends defining a longitudinal axis therebetween;
a control member comprising a tubular portion and a control portion slidably coupled to the handle member, the control portion being directable axially with respect to the handle member between distal and proximal positions;
a tubular outer member attached to a distal end of the tubular portion of the control member and extending distally therefrom;
the tubular outer member being directed proximally as the control portion is directed between its distal and proximal positions;
an elongate inner member secured to the handle member and extending through the tubular portion of the control member into the outer member; and
a treatment element disposed in a lumen of the tubular outer member proximate its distal end, the elongate inner member being configured for holding the treatment element in position when the tubular outer member is being directed proximally, thereby deploying the treatment element from within the lumen of the tubular outer member. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)

29. An apparatus for treating a remote location within a body lumen of a patient, comprising:
-
a handle member having proximal and distal ends defining a longitudinal axis therebetween, and including a lumen extending parallel to the longitudinal axis;
a control member comprising a tubular portion and a control portion slidably received on the handle member, the control portion being directable axially with respect to the handle member between distal and proximal positions;
a tubular outer member extending distally from the tubular portion of the control member, the tubular outer member being directed proximally as the control portion is directed between its distal and proximal positions;
an elongate inner member extending through the lumen in the handle member and through the tubular portion of the control member into the outer member; and
a cooperating rail and wheel on the handle and the control portion of the control member, the wheel engaging the rail for directing the control portion axially upon rotation of the wheel.

30. An apparatus for treating a remote location within a body lumen of a patient, comprising:
-
a handle member having proximal and distal ends defining a longitudinal axis therebetween;
a control member comprising a tubular portion coupled to a control portion, the control portion being slidably coupled to the handle member such that the control portion is directable axially with respect to the handle member to direct the tubular portion axially;
a tubular outer member extending distally from the tubular portion of the control member;
an elongate inner member secured to the handle member and extending through the tubular portion of the control member into the outer member; and
a cooperating rail and wheel on the handle member and the control portion of the control member, the wheel engaging the rail for directing the control portion axially upon rotation of the wheel, thereby directing the tubular outer member axially with respect to the elongate inner member. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38)
