  • Oriented biopsy needle assembly
    Patent number: 5316013
    Abstract: The oriented biopsy needle assembly includes a cannula hub assembly having a cannula hub fixedly attached to the proximal end of a cannula and a barrel member integral with the proximal end of the cannula hub. The barrel member and cannula hub have longitudinally coaxial bore therethrough axially aligned with and extending to the cannula. A pair of inwardly flexible finger pinching arms formed integral with and extending lengthwise over the outer surface of the barrel member are aligned opposite to each other, and each arm has an inwardly extending detent positioned to be downwardly flexed into oppositely aligned corresponding cutout slots of the barrel member. The cannula hub assembly cooperates with a stylet hub at a proximal end, a shoulder portion at a distal end of the hub, and a distal stem portion extending distally from the shoulder portion and terminating at a distal end fixedly attached to the proximal end of a sampling stylet.

  • Oriented biopsy needle assembly
    Patent number: 5249582
    Abstract: The oriented biopsy needle assembly includes a cannula hub assembly having a cannula hub fixedly attached to the proximal end of a cannula and a leg extending proximally from the proximal end of the cannula hub.. The cannula hub has a longitudinal coaxial bore therethrough axially aligned with and extending to the cannula. A stylet hub assembly fixedly attached to a sampling stylet includes a stylet hub at a proximal end, a shoulder portion, and a stem portion extending distally from the shoulder portion and terminating at a distal tip member. The distal tip member is slidably received on a rail of the leg extending proximally from the cannula hub to avoid undesirable rotational movement of the stylet and allow longitudinal movement of the stylet hub assembly on the rail only when the distal tip member is oriented such that the sharpened distal ends of the cannula and sampling stylet are oppositely directed.

  • Needle assembly and method for fabricating same
    Patent number: 4405307
    Abstract: The method is used for fabricating a needle assembly (10) comprising an outer cannula (12), an inner stylet (32), an orienting hub (16) on the proximal end (18) of the cannula (12) and a mating locating cap (40) on the proximal end (38) of the stylet (32).
