20090093818 | INTERGRATED CEMENT DELIVERY SYSTEM FOR BONE AUGMENTATION PROCEDURES AND METHODS - A cement delivery system for vertebroplasty including a rigid cannula having a tubular inner wall defining a central conduit to deliver bone cement and a tubular outer wall extending around the inner wall and spaced apart therefrom to define a peripheral conduit for aspirating bone fluids. Aspirating means communicate with a proximal outlet port of the peripheral conduit to create a pressure gradient between the central conduit and the peripheral conduit to provide a hydraulic force guiding the displacement of bone fluid and the flow of cement. Also, a bone cement delivery system including a rigid cannula having a tubular inner wall defining a central conduit, a tubular outer wall extending around the inner wall and spaced apart therefrom to define a peripheral conduit, and a tubular middle wall extending between the inner and peripheral walls and spaced apart therefrom to define a middle conduit around the central conduit. | 04-09-2009 |
20100087827 | METHOD AND APPARATUS FOR MONITORING AND/OR CONTROLLING THE CURING OF CEMENTS USED IN MEDICAL PROCEDURES - A system for monitoring a cement that undergoes polymerization during curing such as most bone and dental cements by passing an electrical signal through the cement to determine the swelling phase, the initiation of polymerization of the cement and the effective working phase. The system further can control the swelling phase to reduce the time from the mixing of the cement to the initiation of the polymerization by using a ultrasonic signal or by heating the cement and can control the effective working phase after the polymerization has been initiated in order to prolong the working phase by cooling the cement. | 04-08-2010 |
20100286616 | Cannula assembly with detachable inner and outer cannulas - A cannula assembly for injecting implant material into a bone, including an inner cannula defining a central conduit including a first proximal port in communication with the central conduit, an outer cannula surrounding the inner cannula to define a peripheral conduit, and a connector interconnecting the cannulas and detachable from at least one of the cannulas, and at least one of the connector, the first cannula and the second cannula including a second proximal port in communication with the peripheral conduit defined along a direction different than a longitudinal axis of the first and second cannulas. | 11-11-2010 |
20130123790 | BONE CEMENT DELIVERY SYSTEM - A bone cement delivery unit having a rigid support structure with a first portion configured to engage and retain a bone cement reservoir against its casing, a second portion supporting a transmission system and a third portion supporting and guiding a slidable push rod along the injection direction. The delivery system may include a control unit sliding the push rod opposite to the injection direction before stopping the push rod if the quantity of the bone cement pushed out of the reservoir has reached at least a predetermined minimum value, such as to eliminate residual flow. Also, the delivery system may include an adaptor including members electrically connected to the control unit, with the cement reservoir including a sensor for monitoring curing of the bone cement in electrical contact with the members of the adaptor. | 05-16-2013 |
20130190680 | INTEGRATED CEMENT DELIVERY SYSTEM FOR BONE AUGMENTATION PROCEDURES AND METHODS - A bone cement delivery system for vertebroplasty with a cannula having a rigid metal tubular inner wall surrounding a central conduit with a distal outlet port, a rigid metal tubular outer wall extending around the inner wall to define a peripheral conduit with a distal inlet port in the form of fenestrations defined in the tubular outer wall, unobstructed and directly exposed to an environment of the delivery system, a proximal inlet port in communication with the central conduit and a proximal outlet port in communication with the peripheral conduit. A vacuum pump communicating with the proximal outlet port of the peripheral conduit applies a pressure in the range of 10 to 100 KPa to create a pressure gradient between the central conduit and the peripheral conduit to produce a difference in flow rate between the conduits guiding the displacement of bone fluid and the flow of cement. | 07-25-2013 |
