International Classification:

A61B 17/04
A61B 17/56

US Classification:

606232, 606 72

Abstract:

A bone anchor for securing sutures or cables within a hole opening in a bone includes a screw element and a washer, which is separate from and independent of the screw element. The end of the cable to be secured within the bone hole opening is knotted or otherwise secured to the washer, thereby isolating the cable from the twisting of the screw element during insertion of the anchoring device into the hole opening in the bone.

International Classification:

B26B 13/00

US Classification:

30258, 30289, 83907

Abstract:

A cutting device for trimming a coiled strand, such as an arterial, urinary or other intraluminal stent made from metal or plastic wire, has a pair of articulating arms connected at a pivot joint. One of the arms has a holding jaw for holding the coiled strand. A second of the arms has a jaw with a cutter. The holding jaw has a passageway through which the coiled strand may be threaded to aid in holding the coiled strand for cutting by the cutter. The holding jaw preferably has a guide channel formed by a pair of tapered walls that slide between adjacent turns of the coiled strand. In accordance with a method of the invention, an end of the coiled strand is introduced through the passageway in the holding jaw. The coiled strand is rotated to advance the coiled strand through the passageway until the coiled strand is positioned beneath the cutting jaw at the selected location. The lever portions and the jaw portions are then urged together, cutting the coiled strand at the selected location.

US Classification:

604117, 604411, 604192, 12820024

Abstract:

A method and apparatus for injecting fluid into areas having high density tissue that creates a high backpressure resistance on the injection device is disclosed. The high backpressure resistance is overcome through a mechanical advantage achieved by using a secondary reservoir having a cross-sectional area smaller than the cross-sectional area of a primary reservoir. Exemplary injection device reservoir housings may comprise a primary reservoir, a secondary reservoir, a check valve, a septum penetrating cannula, travel limits, a pen needle connecting portion, sliding seal guide ribs, a sliding seal, a pen needle assembly, a needle stop, and a patient needle.

Appl. No.:

Inventors:

Ronald W. Marsh - Hackettstown NJ, US

Assignee:

Becton, Dickinson and Company - Franklin Lakes NJ

International Classification:

A61M 5/00

US Classification:

604117

Abstract:

A needle assembly including a cover, an inner shield, a needle and a hub assembly is provided. After use, the cover is placed over the distal (patient) end of the needle and the inner shield can be used to cover the proximal (non-patient) end of the needle. The inner shield comprises flexible extensions above its open end to secure the inner shield over the proximal end of a needle in the needle assembly. A needle hub is also provided that eliminates adhesive bumps at the base of the needle and further distributes needle angular bending along an irregular surface, which facilitates proper insertion technique and effective needle length. The hub further includes stanchions or castellations on its edge such that when the patient uses proper injection techniques, the edges of the hub leave a distinctive impression in the skin of a user for a short period of time.

International Classification:

A61M005/178

US Classification:

604/164090, 604/170030

Abstract:

An epidural needle has an elongate tube defining a longitudinal axis having a proximal end, a distal end and an axial hollow bore therethrough. The needle has a hub with a proximal end, a distal end and an open passageway having an inside diameter therethrough, the hub being attached to the elongate tube so that the hollow bore of the elongate tube is in fluid communication and substantial axial alignment with the open passageway. The hub further has a cavity disposed between the proximal end and the distal end of the hub. There is a resilient member with an opening therethrough that has an inner diameter disposed in the cavity so that the opening is substantially axially aligned and in fluid communication with the open passageway. The hub of the epidural needle of the invention has a clamp with a releasable latch disposed about the resilient member. The clamp is selectively movable between an open position wherein the inner diameter of the resilient member is substantially unaffected and a clamp/latch position wherein the clamp causes a strain to the resilient member and thereby reduces the inner diameter of the opening through the resilient member.
