Abstract: A device for obtaining selective rigidity with respect to a patient is provided. The device includes a scaffold that is arranged to be flexible when in a first relaxed configuration, wherein the scaffold is configured to become substantially more rigid when a suction force is applied thereto. The scaffold comprises first and second opposing outer flexible layers that are sealed together to form a plurality of elongate pockets therein, and an expanded structure disposed within the plurality of elongate pockets and in communication with a vacuum port that receives the suction force.

Abstract: An elongate access sheath comprises a proximal portion and a lumen. The proximal portion supports a control handle, a brake pad, a tension gear, and a locking trigger. A deflector filament extends through the lumen and is coupled to the tension gear. The tension gear includes an outside and an inner engagement portion. The brake pad comprises a slot and an outside engagement portion. The locking trigger includes a pin disposed within the brake pad slot. The control handle includes a lever and an engagement portion. Upward movement of the lever engages the engagement portion with the outside engagement portion of the tension gear to rotate the tension gear in a first direction and slides the deflector filament to bend the lumen distal portion. Translation of the locking trigger engages the brake pad and the tension gear to prevent rotation of the tension gear in an opposite second direction.

Abstract: A deployment device for repair of a transected body vessel is described herein. Device can have a handle and one or more shafts coupled thereto. A prosthesis being retained by a sheath can be coupled to the delivery device. The sheath can have end portions coupled to one or more shafts. Rotation of a shaft can retract a sheath portion away from either end of the prosthesis for expansion thereof prior to the middle of the prosthesis. Continued rotation of a shaft can completely remove the sheath from the prosthesis, so that the prosthesis is fully expanded and couples the first and second vessel portions of the transected vessel together. Prosthesis may be retained by overlapping a tubular sheath and lacing a threading member therethrough. Prosthesis may be retained by a splittable sheath.

Abstract: Drainage catheters for use in a variety of medical procedures are presented herein. The drainage catheter features an improved tension member locking mechanism. In use, once the drainage catheter is placed as desired, a second connector piece is rotated relative to a first connector piece to wind the tension member around a spooling region and pull the distal end of the catheter tube into a locked configuration. Once the tension member is tensioned, the first and second connector pieces are pulled into a locking engagement thereby securing the catheter tube in the locked configuration.

Abstract: A medical device assembly having a quick release mechanism reversibly engaged with a medical device and a method used by an operator to deploy said medical device at a targeted site in a body vessel is provided. The quick release mechanism generally comprises an inner core wire and an outer coil having a proximal section and distal section. The inner core wire and the outer coil are coupled together proximate to their distal end with the outer coil having an enlarged overall thickness in its distal section. The medical device has an opening sized to receive and to detachably engage the distal section of the outer coil. The quick release mechanism having an engaged position in which the outer coil is securely holds the medical device and a detached position in which the outer coil and medical device are substantially unengaged. The operator causes the quick release mechanism to move from the engaged position to the detached position by moving the inner core wire and outer coil in opposite directions.
