摘要:
A filling apparatus comprising: a plurality of parallel tunnels (12, 12'} formed in a longitudinal body {11, 11') and arranged in a longitudinal direction of said body (11, 11'); and a filler reservoir (20) having an exit end (21) adapted to be in fluid communication with said plurality of parallel tunnels {12, 12'), characterized in that a cross-sectional area of said exit end (21) is less than about 5 times, preferably less than about 3 times, and more preferably about 1.5 to about 1.1 times a total cross-sectional area of said plurality of parallel tunnels {12,12'), wherein the apparatus is configured such that a filler contained in said filler reservoir {20) is driven into said plurality of parallel tunnels (12, 12') via said exit end (21), when said exit end (21) is in fluid communication with said plurality of parallel tunnels (12, 12'); and said plurality of parallel tunnels (12, 12') are separable from said filler reservoir (20) after said plurality of parallel tunnels (12, 12') are filled with said filler.
摘要:
An intramedullary bone device which has an internal lumen defined by a sidewall is described. The sidewall includes first and second perforated regions having respective first and second openings. The device also includes fluid flow directing features to direct the flow of a fluid from the internal lumen of the device through the openings in the sidewall of the device. The device may be part of a system with a fluid introducer member inserted through the internal lumen of the device. A method of securing and/or stabilising a bone including a fractured bone is also described.
摘要:
Devices and method discussed for device for delivering a pressurized substance to an opening in bone within a vertebral column, useful to provide access to structures in the vertebral so that a substance, such as bone cement can be delivered through a lumen or portal or for providing access to the opening in bone by a separate instrument.

A kit of parts for inserting a deformable implant into a cavity in a bone of a patient is described. An inserter instrument (1) comprises a body (100) having a cavity extending along a longitudinal axis from a distal end to a proximal end. An attachment mechanism (108) is provided at the distal end and to which a deformable implant can be releasably attached. A drive mechanism (132) is provided at the proximal end of the body. A push rod (150) is freely and slidably arranged within the cavity and has a distal end engageable with a part of the deformable implant and a proximal end abutable by the drive mechanism. The drive mechanism is operable to drive the push rod toward the distal end of the body. The kit also includes an impactor (210) dimensioned for slidable engagement within the cavity.

Um ein medizinisches Instrument (10) umfassend einen Werkzeugabschnitt (12) mit einem ersten Werkzeugelement (66) zum in Eingriff Bringen mit einem korrespondierenden zweiten Werkzeugelement (16) an einem Implantat (18) so zu verbessern, dass Implantate, insbesondere Knochenschrauben, einfach und schnell implantiert werden können, wird vorgeschlagen, dass es einen am oder im Instrument angeordneten oder ausgebildeten Knochenzementbehälter (50) umfasst.
摘要:
A bone cement mixing and delivery system comprises a mixer with a mixing chamber and a paddle and a piston moveably disposed therein. An electrically actuated drive assembly moves said paddle in and said piston through the mixing chamber. A delivery device has a reservoir for receiving mixed bone cement discharged from the mixing chamber with a proximal end opening and a delivery port in the opposed distal end. A plunger is disposed within the reservoir and has a head for moving from the reservoir proximal end opening towards the reservoir distal end to drive cement out of the delivery port. The reservoir has an entry port and a transfer conduit extends from a mixing chamber exit port to the reservoir entry port for transferring the cement into the reservoir. A one-way valve allowing flow into and preventing flow out of the reservoir is mounted to the reservoir entry port.
