Abstract: A multi-functional nasogastric tubular device for insertion into a patient includes an elongated flexible body having a pair of spaced apart opposite proximal and distal ends, a plurality of spaced apart lumens formed in the body so as to extend side-by-side with respect to one another between the proximal and distal ends of the body and being open at least at the proximal end of the body, and a temperature sensor disposed on the body, such as in one of the lumens of the body, and running from the proximal end of the body to the distal end thereof such that the temperature sensor is adapted to monitor internal core temperature of a patient and also to serve as a radiopaque element for marking the position of the elongated body in the patient.

Abstract: A racket frame, such as for a tennis racket, has a head portion, a handle portion and a throat portion extending between and interconnecting the head and handle portions. The head portion encompasses an open region and has a first plurality of stringing holes for attaching stringing to the head portion and across the open region. The throat portion is in the form of a pair of legs in a generally V-shaped configuration. The frame also includes a second plurality of non-stringing holes defined in one or both of the head and throat portions for forming voids in the material thereof to reduce the weight and tailor the stiffness thereof in a manner which reduces axial and torsional deflections of the head portion upon striking a ball by the stringing across the open region of the head portion.
