An endoscopic intracorporeal suture tying aid allows a suture to be looped around itself multiple times and cinched, enabling a throw of a surgeon's knot to be easily made. The tying aid includes a needle holder connected to a proximal end of a shaft for releasably holding a needle; a hook that slides longitudinally with respect to the beaks; and the shaft being axially rotatable with respect to the hook.

A drill guide is disclosed including a sleeve mounted on a handle. The sleeve of the drill guide has a bore which is dimensioned for slidably receiving a bit sizing ferrule therein. The bit sizing ferrule has a sized bore for demountably inserting a drill bit or other instrument therein having a particular width.

A wound closure device employs a porous bonding member which receives a flowable adhesive capable of providing long term wound support. The bonding member is positioned by a carrier member that is used to achieve initial apposition of the wound and which may later be removed. An intermediate barrier may be provided between the bonding pad and the wound site. Alternatively, a rigid applicator may be utilized for positioning the bonding pad at the wound site. The closure device can include a supply of flowable adhesive for adhering the bonding member to the skin of the patient. Suitable flowable adhesives are cyanoacrylates. A form of packaging supports the wound closure member for preapplication of the adhesive and can serve as a part of a sterile barrier package. In one embodiment, strips are placed on opposite margins of a wound which have porous portions. The porous portions have a porosity which is sufficient to permit flowable adhesive to permeate through them to bond the strips to opposite margins of the wound.

Wound closure means using flowable adhesive

A linear surgical stapling instrument includes a magazine for holding a plurality of undeformed surgical staples, and an upper jaw carrying the magazine and having opposed distal and proximal ends. An anvil is formed with staple-deforming pockets, and a lower jaw carries the anvil and has opposing distal and proximal ends respectively configured to mate with the distal and proximal ends of the upper jaw thereby to place the magazine and the anvil in confronting relation. A staple driver is carried in the upper jaw for driving staples held therein toward the anvil. Further, the upper and lower jaws are configured such that, when their respective distal and proximal ends are mated, a gap exists between the jaws in an intermediate region between their respective distal and proximal ends. Finally, a pivotably mounted clamp bar joins the upper and lower jaws and when actuated compresses them together in the intermediate region thereby to narrow the gap and to increase the clamping pressure between the magazine and the anvil. The instrument also includes a blocking system that prevents the jaws from being remated, once having been mated and having had staples in the magazine driven toward the anvil. Still further, the instrument includes a coupling device for coupling the jaws and clamp bar together when the staple driver is actuated.

An applicator for applying a strap around a vein at the site of a defective venous valve includes a handle portion and a removable cartridge. One end of the strap is anchored on the anvil of the cartridge and the free end is looped around the vein and passed through an opening in the cartridge to overlie the anchored end. The free end of the strap is connected to a strap puller within the cartridge which is coupled to a strap puller extension within the handle when the cartridge is inserted in the handle. The perimeter of the loop is adjusted by moving the tensioner on the handle. When the loop perimeter is at its desired value, the triggers on the handle are pressed to drive a staple through the overlying portion of the strap. A knife within the cartridge cuts the excess strap from the loop.

Upon inhalation of air from the interior of a housing, a flexible diaphragm-type valve exposed to the ambient air surrounding the housing is moved inwardly due to the difference in ambient air pressure to that in the housing to expose the interior of the housing to the ambient air which is then drawn into the housing. Upon movement of the valve, it strikes a lever connected to a toggle linkage arrangement, causing the lever to pivot to break the toggle linkage, enabling a coil spring to extend and move a dispensing nozzle into contact with the valve stem of a medicant-containing, aerosol valve actuated, bottle. The valve stem is urged upwardly by the nozzle and moved into the interior of the bottle dispensing a dose of the medicant to be mixed with the inhaled air, which is inhaled by the user. The bottle is housed in a storage chamber having a reciprocably sliding cap mounted therein which can be manually moved to reset the nozzle and toggle linkage in its locked position, to prevent the nozzle from opening the aerosol valve and ready the device to dispense a dose of medicant once inhalation is repeated.

Breath-activated inhalation device

Upon inhalation of air from the interior of a housing, a flexible diaphragm-type valve exposed to the ambient air surrounding the housing is moved inwardly due to the difference in ambient air pressure to that in the housing to expose the interior of the housing to the ambient air which is then drawn into the housing. Upon movement of the valve, it strikes a lever connected to a toggle linkage arrangement, causing the lever to pivot to break the toggle linkage, enabling a coil spring to extend and move downwardly a medicant-containing bottle relative to the valve stem of an aerosol valve. The valve stem is urged upwardly relative to a nozzle and moved into the interior of the bottle dispensing a metered dose of the medicant to be mixed with the inhaled air, which is inhaled by the user until the valve automatically closes by extension of the valve stem relative to the nozzle. The bottle is moved upwardly by a pushbutton to reset the toggle linkage actuation means and hold the bottle relative to the nozzle with its valve stem extended. Upward movement of the bottle cocks and resets the toggle linkage to a locked position precluding downward movement of the bottle until the inhalation cycle is repeated.

A reservoir outlet control device for controlling fluid flow from a reservoir. The device is particularly suitable for controlling fluid outflow from a blood collecting and blood delivery reservoir.

The disclosure relates to a protector in the form of a rigid plastic disk which bites into and displaces material on the shell portion of a needle cover cap to protect a user from accidental sticks injuries while recapping the needle.

Safety device for hypodermic syringe to prevent stick injuries

An autotransfuser that includes, in a single receptacle, a pair of chambers separated by a common wall. Each receptacle can alternately perform, a blood infusion or blood collection function. Each chamber includes at least three inlets/outlets, a blood inlet, a blood outlet and an air inlet means In some embodiments of the invention the air inlet means serves alternately to couple either an air or a pressure source on the one hand or a vacuum source on the other hand to the corresponding chamber. In other embodiments of the invention, the air inlet means comprises a vacuum inlet and a separate air or pressure inlet. A disk like device or valve manifold is arranged for rotatable movement adjacent the inlets/outlets. The disk like device includes four channels, one for each of air or pressure, vacuum, blood collection and blood infusion. Each channel includes a port for coupling to external tubing and at least one channel end. The channel ends are located in the disk like device so that by rotating the disk like device to two distinct positions, one or the other of the functions can be performed by each chamber. A blood valve is also disclosed which has a float element having a specific gravity which allows it to float in a pool of human blood and a significant closure force in excess of about ten to fifteen grams.

A surgical stapler for implanting and clinching staples in the body of a patient employs a reciprocally movable, retractable anvil and a reciprocally movable former for forming a staple about the end of the retractable anvil. A toggle is mounted in a stapler trigger which simultaneously actuates the former and toggle. The toggle removes the anvil end into and out of the path of the former whereby desired release of a formed staple from the anvil is assured following clinching of the staple ends.
