Abstract: A method for packaging an agent for delivery within a body cavity. A reservoir within a package contains a specified quantity of the agent and is either contiguous with, or coupled to, a dispensing node such as a swab. Depth of insertion of the dispensing node into the body cavity is restricted to a specified depth by a penetration-restricting feature that forms part of the package.

Abstract: A medical device for delivery of a fluid to a patient from a line terminating in a tubing needle. The medical device includes a cannula assembly for coupling the fluid into a cannula that is inserted into the patient. The cannula assembly has a first locking element disposed in a fixed position with respect to the cannula. Coupling the line to the cannula assembly is an infusion flap. The infusion flap includes a second locking element for engaging the first locking element of the cannula assembly and a lift tab for disconnecting the infusion flap from the cannula assembly. Coupling of the first and second locking elements requires initial mating of the infusion flap and cannula assembly followed by locking through rotation of the infusion flap with respect to the cannula assembly.

Abstract: A Classical guitar, comprised of a full size neck and bridge, where the dimensions of the neck and the bridge are the same as a conventional instrument. The instrument body normally used to produce sound by acting in resonance with the strings is replaced by a mechanically isolated bridge and electronic pickup which are mounted on a compact chassis. Adjustable supports are affixed to the chassis. The supports contact the player in such a manner as to hold the guitar in the correct Classical position. Integral electronics support the use of headphones for practice, and speakers for performance.
