1. An apparatus for applying an inward force to a medical device comprising:
- a blade constraining member;
a first mount rotatable with respect to the blade constraining member;
a first plurality of blades arranged to form a first chamber whose size may be varied by rotating the first mount with respect to the blade constraining member, each blade of the first plurality of blades pivotally connected to the first mount;
a second mount rotatable with respect to the blade constraining member;
a second plurality of blades arranged to form a second chamber whose size maybe varied by rotating the second mount with respect to the blade constraining member, each blade of the second plurality of blades pivotally connected to the second mount;
wherein the blade constraining member is engaged with at least one blade from the first plurality of blades and with at least one blade from the second plurality of blades.

Abstract
An apparatus for applying an inward force to a medical device may include at least two independently operable sections. Each section may include a plurality of movable blades arranged to form an aperture or chamber whose size may be varied. Each blade may be pivotally connected to a mount and slidably engaged with a constraining member. The blades are movable so as to allow the aperture to be sized to contain the medical device and to alter the size of the aperture.

22. An apparatus for applying an inward force to a medical device comprising:
-
a plurality of blade constraining members; a first mount having a plurality of first blades arranged to form a first chamber, each first blade being pivotally attached to the first mount; a second mount having a plurality of second blades arranged to form a second chamber, each second blade being pivotally attached to the second mount; each blade having a slot; each blade constraining member passing through the slot of a first blade and through the slot of a second blade; wherein the size of the first chamber maybe adjusted by rotation of the first mount relative to the blade constraining members; and wherein the size of the second chamber may be adjusted by rotation of the second mount relative to the blade constraining members.

23. A method of reducing the size of a medical device, the method comprising the steps of:
-
providing an apparatus for applying an inward force to a medical device, said apparatus comprising a plurality of blades arranged to form a chamber;
each blade being pivotally secured to a mount;
at least one blade comprising a slot that is slidably engaged with a blade constraining member, the slot having a non-cylindrical opening with a lengthwise axis, a pivot point of the blade being offset from the lengthwise axis;
wherein the size of the chamber may be adjusted by rotating the mount with respect to the blade constraining member;placing a least a portion of a medical device within said chamber; and rotating the mount with respect to the blade constraining member to reduce the size of the chamber, thereby reducing the size of at least a portion of the medical device. - View Dependent Claims (26, 27, 28, 29)

24. A method of reducing the size of a medical device, the method comprising the steps of:
-
providing an apparatus for applying an inward force to a medical device, said apparatus comprising a plurality of first blades arranged to form a first chamber;
each first blade being pivotally secured to a first mount at least one first blade being slidably engaged with a blade constraining member;
wherein the size of the chamber may be adjusted by rotating the first mount with respect to the blade constraining member, the apparatus further comprising a plurality of second blades arranged to form a second chamber, each second blade being pivotally secured to a second mount;
at least one second blade being slidably engaged with said blade constraining member;
wherein the size of the second chamber may be adjusted by rotating the second mount with respect to the blade constraining member;placing a portion of a medical device within said first chamber and a portion of the medical device within said second chamber; rotating the first mount with respect to the blade constraining member to reduce the size of the first chamber thereby reducing the size of at least a portion of the medical device; and rotating the second mount with respect to the blade constraining member to reduce the size of the second chamber, thereby reducing the size of a second portion of the medical device. - View Dependent Claims (25)
