Abstract: The invention concerns a device for the two-way transfer of a liquid (38) between a bottle (14) provided with a cap (44) capable of being perforated at a cartridge (12) comprising a cylindrical reservoir (26) wherein slides a piston (34) capable of being perforated. It comprises: a body (16) including means to be fixed on the bottle (14); a member (24) linking the piston (34) capable of being perforated to the body (16); a shuttle (20) relative to the body (16) and said linking member (24), the shuttle bearing a hollow needle (22) whereof one first end (112) is adapted to pierce the piston (34) and whereof the second end (114) is adapted to pierce the cap (44). The shuttle (20) is mobile between a piston wherein the needle ends (112, 114) are spaced apart from the piston (34) capable of being perforated and the cap (44) capable of being perforated and an end-of-stroke transferring position wherein the needle ends (112, 114) are received in the cartridge (12) and the bottle (14).

Abstract: An injection syringe having a body (12) bearing an injection needle (14), a reservoir (16) containing a liquid (42) to be injected and being movable relative to the body (12) for causing the liquid to be injected to circulate through the needle (14), and a needle shield (18) movably mounted relative to the needle (14) for movement, under the control of a spring (20), from a retracted position towards an active protective position. The syringe has complementary parts (54, 62) which, when engaged, retain a first spring (20) end cooperating with the shield (18), and which, when disengaged by further movement of the reservoir (16), release the spring (20) first end to displace the shield (18) to its active protective position. The second spring (20) end is pressed against the reservoir (16) for gradually compressing the spring (20) during injection.

Abstract: An injection syringe (10) has an elongated syringe body (12) including a tube (18), a perforated front wall (26) for receiving an injection needle (70), and a rear actuating plunger (14) movably mounted inside the tube (18). A mobile needle shield (16) is externally movable along the syringe body (12) between a retracted position and an active position. An axial coupling mechanism (54) is provided between the shield (16) and the actuating plunger (14) for their simultaneous displacement towards the front on a common section. A release mechanism (58) is provided for releasing the coupling mechanism (54) to disengage the actuating plunger (14) and the needle shield (16) when the needle shield (16) is finally set in place.

Abstract: The invention concerns an injection syringe (10) comprising a syringe body (12) bearing an injecting needle (22) and an actuating piston (14) movably mounted in the body (12). The injecting needle (22) extends axially inside the body (12) up to a rear end (22B) on one side of which is initially arranged in the body (12) a transverse wall (90, 96) capable of being perforated. Said transverse wall (90, 96) is movable relative to the needle from an initial position in which the transverse wall (90, 96) is at some distance from the needle (22) to a final position in which the transverse wall (90, 96) is pierced by said needle (22). The syringe comprises rigid means (64) for axially guiding the rear end (22) of the needle when the transverse wall (90, 96) is being pierced.

Abstract: The balloon inflating device comprises a syringe (12) the plunger (28) of which has a screw thread (36). It further comprises a mechanism for retaining the plunger comprising a first half nut (40A) movable between a position separated from the screw thread (36) and a position of engagement with the screw thread (36), and a slidable control element (42) which comprises first coupling means (54A) adapted to displace the first movable half nut (40A). The retaining mechanism (14) further comprises a second movable half nut (40B) movable between a position spaced away from the screw thread (36) and a position of engagement with the screw thread (36). The control element (42) further comprises second coupling means (54B) associated with the second half nut (40B) and adapted to move the second half nut. The first and second coupling means (54A, 54B) are mechanically connected to each other in the region in which the control element (42) is coupled to the first and second half nuts (40A, 40B).

Abstract: The invention concerns an injection syringe (10) comprising a syringe body (12) bearing an injecting needle (22) and a rear actuating piston (14) movably mounted in the body (12). It further comprises a mobile protector (36) of the end (22A) of the injecting needle, movable between a retracted position in the body (12) and an active protecting position in which the front end or the protector (36) is in front of the injecting end (22A). The protector (36) and the syringe body (12) comprise protuberances associated (44, 102) by projections and recesses for maintaining the protector (36) in its active protecting position. The syringe comprises a member (66) for positively retaining in locked position the protuberances associated (44, 102) by projections and recesses when the needle protector (36) is in active protecting position.

Abstract: A surgical staple inserter for joining two ducts such as a blood vessel and a blood prosthesis. The staple inserter ejects staples in a radial direction relative to the axis of the ducts. In one embodiment, it includes a staple holder surrounded by the prosthesis and containing a series of staples arranged in at least one ring. All the staples are ejected simultaneously. The staple inserter also includes an anvil outside the organic duct, and a device for spacing apart the anvil and the staple holder in relation to their relative working positions. Projections hold the prosthesis in place during the insertion of the staple holder into the ducts.
