Abstract: This device employs an elastic, thin walled tubular member which can be a finger receiving and enclosing portion of a rubber glove or a rubber finger cot. The tubular member has a closed end for engaging the wearer's fingertip and an open end through which extends a flexible tube having a beveled end secured to the inner side of the closed end of the tubular member. The tube extends through a palmar portion of the glove or along the palm of the wearer of the cot, where an external portion of the tube is exposed for insertion of a biopsy needle. The tube has an axial passage through which a biopsy needle can be guided to pierce the closed end of the tubular member and a site inside a body cavity being palpated by the wearer, while the needle pierces the site to remove a sample of tissue to be examined after the needle is withdrawn from the tube.

Abstract: A sail for a wind driven craft includes a panel having a multiplicity of pockets disposed in contiguous rows, and staggered with respect to pockets in adjacent rows, and aligned with pockets in alternate rows, to define a honeycomb array. Open ends of the pockets may be polygonal and have curved inner walls with closed ends. External sides of the pockets are convex. Each pocket has an infinite number of diametral planes dividing the pocket into two spaces of equal volume. The panel may have a peripheral flange overlapping peripheral pockets.
