摘要： A regular metallic, cylindrical tubular needle cannula (1) is subjected to a metal etching liquid (5) in the inside lumen (11) thereby increasing the inside diameter and enhancing the flow properties while maintaining the outside appearance. The inside diameter is only increased over a controlled length (14) of the full length of the needle cannula (10) leaving sufficient length and wall thickness to also taper the outside diameter if so wanted.

摘要： Methods and apparatuses for fabricating a needle assembly which includes a blunt in a cannula of a needle. In one example of a method, at least one blunt is collected in a cutout of a blade from a set of blunts and a fluid is passed across said cutout. Any further blunts around the cutout are dislodged by the fluid, leaving only one blunt on the blade. In another example of a method, a blade is moved to a first position to collect at least one blunt from a set of blunts, and the blade is moved to a second position to singulate the one blunt from the set of blunts; the blade has a tip end which is designed to capture securely only one blunt, wherein any further blunts are not securely maintained in the tip end. An exemplary apparatus includes a container for holding a set of blunts, a motor, and a blade coupled to the motor and disposed at least partially within a slot of said container. The blade includes a tip end which is designed to capture securely only one blunt.

摘要： A process for manufacturing wire or needles having a taper point and mechanically drilled suture mounting holes in the proximal ends. Needle or wire blanks are cut from a roll of wire and mounted to a carrier strip. The carrier strip and needles are moved through a succession of forming and trimming and grinding stations. The blanks are coined in a coining die to produce lateral wings of constant thickness. The blanks are preferably rotated in the strip while being ground. The strip and needle blanks are then moved to a bank of at least two drills wherein the proximal suture mounting ends of the needles are drilled.
