  • Publication number: 20200269013
    Abstract: A tubular sheath for enclosing an expandable balloon attached to the distal portion of a catheter encloses and protects the expandable balloon. The tubular sheath is configured to be slidable and removable from the catheter. The tubular sheath may include a longitudinal splitting element that is removable as a result of a force applied to the longitudinal splitting element. The longitudinal splitting element is configured to split the wall of the tubular sheath in response to the force. Alternatively, the tubular sheath may include a gripping portion that has relatively poor cohesive strength to adjacent portions of the tubular sheath. The tubular sheath is configured to be removable in response to a force applied to the gripping portion.

  • Patent number: 10668255
    Abstract: A medical device includes a catheter, an expandable balloon on the distal portion of the catheter, and a sheath that is configured to enclose and protect the expandable balloon. The sheath extends within a sheath lumen of the catheter and out from the catheter through a distal opening of the sheath lumen. When in a deployed configuration, the sheath extends proximally to enclose at least a portion of the expandable balloon. The sheath may be axially movable within the sheath lumen of the catheter to actuate from the deployed configuration to a retracted configuration. In moving to the retracted configuration, the sheath may expose the outer surface of the expandable balloon.

  • Publication number: 20170020700
    Abstract: A method of forming a stent includes the steps of forming a composite member into a stent pattern, forming openings through an outer member of the composite member, processing the composite member to remove a portion of the composite member without adversely affecting the outer member, and swaging the outer member to create a plurality of lumens. The composite member may be formed of an outer member with an hourglass-shaped inner member, wherein the processing step removes the inner member and the swaging step forms two lumens from the hourglass shaped cavity. The composite member may be formed of an outer member, an inner member, and an intermediate member, wherein the processing step removes the intermediate member and the swaging step presses portions of the outer member into contact with the inner member to form two lumens separated by the inner member.

  • Publication number: 20130001052
    Abstract: A mechanical interlock socket outlet includes a female receptacle mounted to a face plate, a breaker box, a toggle switch for activating the breaker box, and an actuating rod for operating the toggle switch. A locking arm is provided for engaging the actuating rod and has a first position and a second position. A safety release saddle plate is engaged to the actuating rod. The plate has a locking arm release portion such that movement of the plate will contact the locking arm and move the locking arm from the first to a second position. Springs are connected between the plate and the face plate, and connected to a portion of the saddle plate adjacent a top portion of the plate. The springs act to return the saddle plate and toggle switch to a locked position. A push pin is provided to move the saddle plate.
