Abstract: An implantable flow connector for fluidically coupling a source tissue-enclosed body space with a destination element, comprising: a conduit having a lumen terminating at an orifice at a first end of the conduit implantable in the source body space through an opening formed in a tissue wall of the source body space, and a second end of the conduit implantable in the destination element through an opening in a surface of the destination element; and a circumferential flange, radially extending from the conduit proximate the conduit first end, configured to be implanted in the source body space adjacent an opening in the tissue wall of the source body space such that the conduit extends through the opening, the flange comprising one or more circumferentially adjacent sections at least one of which has a rigidity that decreases in a radially-increasing direction.

Abstract: A paper feed system for use in a printing apparatus that detects multi-feeds and separates all sheets while allowing a single sheet to continue into the machine includes a nip with a drive roller for feeding sheets. A reversible pressure roller downstream of the drive roller is connected to a motor, but idles in the direction of the paper feed in normal operation. When a multi-feed is detected, the motor is turned ON and the reversible pressure roll actuated by a controller. The reversible pressure roller has more friction with the sheet in its contact than the friction between sheets. This drives the sheet in contact backwards.

This sheet can be diverted to a separate paper path using a gate mechanism and, if desired, fed back into the feed path.

Abstract: A facet joint clamp to fix spine facet joints in a spine of a mammalian patent, the clamp including: a first plate and second plate each including a jaw section and a base, wherein the base is at an acute angle with respect to the jaw section, and the jaw section has an inside surface adapted to grasp the spine; a hinge in the base section of the first and second plates and forming a pivot joint between the plates and an adjustment mechanism to controllably pivot the first plate with respect to the second plate.

Abstract: A spinal implant include a top, wherein at least a portion of the top is configured to contact a first vertebra, a bottom, wherein at least a portion of the bottom is configured to contact a second vertebra, a side having a releasable attachment to receive an insertion device and a cam surface to engage a cam on the insertion device

Abstract: A medical/surgical irrigator comprising a handpiece and a tip assembly that is removably attached to the handpiece. Internal to the handpiece is a variable speed pulse pump from which irrigation fluid is discharged through the tip assembly. A single, variable speed motor regulates the pumping rate of the pump. The tip assembly includes a suction wand through which the discharged fluid is drawn away from the site to which the fluid is applied.
