Abstract: A bone cement mixing and delivery system including a mixer, a delivery device, and a flexible extension tube. A connector is attached to a distal end of the flexible tube. The connector includes a housing, a spindle configured with a fitting, and an enlarged knob. The spindle is seated within the housing and is configured to rotate between a closed and open position. In the open position, the spindle allows flow from the delivery device flexible extension tube into a bore of the spindle and into the spindle fitting. A delivery cement cannula is attached to the spindle fitting for allowing cement to travel from the delivery tube into living tissue. The enlarged knob is used to rotate the spindle from an open to a closed state and vice versa.

Abstract: A bone cement mixing and delivery system including a mixer and a delivery device. The mixer includes a paddle for mixing the components and a piston that pushes the mixed cement into the attached delivery device. The delivery device includes a tube into which the bone cement is forced from the mixer, and a plunger that forces the cement out of the tube during the medical procedure. The tube includes an entry port through which cement is introduced into the tube from the mixer. A one-way valve attached to the tube allows the cement to flow from the mixer through the entry port. After the cement is loaded in the tube, the delivery device is removed from the mixer. The valve blocks flow out of the entry port when the plunger is depressed.

Abstract: Aspects of this invention disclose devices and methods for attachment of a gastrointestinal sleeve. In some embodiments, the attachment device comprises a flexible cuff, a gastrointestinal sleeve interface, and a gastrointestinal sleeve. Some aspects of the invention contemplate the use of T-tags for attachment of the cuff to tissue. In some aspects of the invention, attachment of the sleeve to the cuff is achieved using various fasteners.

Abstract: A bone cement mixing and delivery system is provided in which separate components of bone cement are mixed together in a mixer to form a bone cement mixture. The mixer includes a paddle for mixing the components in a mixing chamber and a piston that pushes the mixing cement into an attached delivery device. The system further includes a switch that disconnects the drive assembly that actuates the paddle and piston from its power source. The switch is automatically tripped by a follower that moves upon actuation of the drive assembly. Once the cement is mixed and transferred to the delivery device, the follower trips the switch to automatically deactivate the drive assembly.

Abstract: A bone cement mixing and delivery system is provided in which separate components of bone cement are mixed together in a mixer to form a bone cement mixture. The mixer includes a mixing paddle and a mixing shaft connected to the mixing paddle. A motor operatively engages the mixing shaft to rotate the mixing shaft and the mixing paddle to mix the components in a mixing chamber. The motor also operatively engages a transfer mechanism. After a predetermined mixing period has elapsed, the motor automatically actuates the transfer mechanism to transfer the mixture to a delivery device. The mixture is then delivered to a target site, such as a vertebral body of a patient or other anatomical site.
