In order to deliver porous particulate material into a cavity via a thin tube without substantially crushing the porous particulate material, a two-step process and an apparatus for use therein are provided. The two-step process involves inserting a first rod into the thin tube to push the porous particulate material therein; removing the first rod from the tube; and (a) inserting a second rod into the thin tube, or (b) joining a second rod with the first rod, and inserting the joined first rod and second rod, to push the porous particulate material which remains in the thin tube. In (a), the first rod has a cross sectional area significantly smaller than that of the thin tube, and the second rod has a cross sectional area which is about equal to that of the thin tube. In (b), each of the first rod and the second rod has a cross sectional area about half of the thin tube.

Disclosed is an implant through which a liquid or pasty material can be injected in a targeted manner. This implant is composed of: a main implant with a lumen extending along its entire length, the body of the main implant being of hexagonal cross section, with the plane faces drilled with internally threaded holes which open into the lumen and are intended to remain open or to be plugged by one or more micro screws of the complementary implants, the distal end and proximal end of the implant being threaded; one or more complementary implants, for each of which the micro screw thereof, intended to cooperate with the internally threaded holes of the main implant, is connected to its insertion sleeve by way of a separable zone. The implant is intended in particular for surgical interventions.

Systems for augmenting a vertebral body. A deformable conduit assembly includes a hub defining an opening, and a deformable conduit within which a steering instrument is removably disposed. The deformable conduit may be curved by the steering instrument. An expandable member assembly includes a catheter tube slidably positioned through the opening of the hub and a cannula handle of an access cannula, and an expandable structure. The deformable conduit may be moved proximally relative to the hub and the expandable member assembly to expose the expandable structure within the vertebral body. The hub may define one or more guiding slots though which one or more arms are slidably positioned. An axial controller may be coupled to a proximal end of the deformable conduit. The axial controller is configured to receive an input to expose the expandable structure by moving the deformable conduit relative to the hub and the access cannula.

The invention relates to a delivery system, device and method for delivering biomaterials for fracture fixation (including augmented fixation), in particular, for delivery of bone cements. The mixing system ensures the biomaterial only commences setting upon extrusion from the mixer, cannula or during injection through an appropriate internal fracture fixation device, allowing for rapid closing by the surgeon. The system also permits the surgeon to cease injecting the cement for an extended period of time before continuing the injection in another area using the same cartridge, through the simple removal of one mixer and attaching another in its place. The invention also provides a method of delivery of biomaterials to a desired implantation site.

A device for producing a bone cement dough from a monomer liquid and a cement powder and dispensing the bone cement dough. The device includes a cartridge holding the cement powder in an internal space. A monomer receptacle screws onto the cartridge, forms a chamber, and has a plunger with a passage that is permeable to gases and the monomer liquid but is impermeable to the cement powder and that connects the internal space to the chamber. The plunger tightly closes the internal space with the exception of the passage. A gas supply opening is arranged in the wall of the monomer receptacle. A monomer liquid container holds the monomer liquid and is located in the chamber. An opening facility opens the container, and closes the gas supply opening before opening the container. Also provided is a method for producing and dispensing the bone cement dough.

A medical balloon device includes an outer member extending along an axis. An inflatable member has a proximal end extending from a first end of the outer member and a distal end. An inner member is positioned within the outer member and the inflatable member such that a first end of the inner member is coupled to the distal end of the inflatable member. A support member is movably disposed within the inner member and includes a first end configured to removably engage the first end of the inner member. Translation of the support member along the axis causes the inflatable member to move between a first position in which the inflatable member has a first length and a first profile and a second position in which the inflatable member has a second reduced length and a second reduced profile. Methods of use are disclosed.

The bioinjection device has a housing including a pistol grip and an elongated barrel. A trigger is pivotally mounted to the housing. An inner shaft having a distal end is slidable between a first position in which the distal end of the inner shaft is disposed in the barrel and a second position in which the distal end of the inner shaft extends past an opening in the end of the barrel. A tip containing a medicament is disposed about the opening of the elongated barrel. The tip includes at least one aperture for dispensing the medicament. One can inject the medicament from the tip into a bone fracture or degenerative bone tissue during surgery by actuating the trigger of the bioinjection device. A configurable tip may be employed to control the amount and direction of dispersion of such medicament.

An integrated targeted kyphoplasty system includes a piercing head, a tube body and a tube body handle. The tube body has an end connected to the piercing head and is provided with a balloon and a guider at an end of the balloon, and another end connected to the tube body handle and provided with a guide knob for controlling the guider to be bent and a pressure pump connector communicating the balloon. The piercing head is provided with a cement outlet, a cement channel is in center of the tube body, and the tube body handle is provided with a cement inlet. The cement outlet, cement channel and cement inlet communicate with each other. The device requires for only one piercing to complete entire KP surgical treatment without changing any tools, greatly decreasing radiation exposure rate of the patient during operation and the pain caused by multiple operations.

The present disclosure relates to a device including an elongated hollow shaft having a proximal end and a distal end. The device also includes a first attachment mechanism coupled to the proximal end of the elongated hollow shaft. The device also includes a rod having a proximal end and a distal end. The rod is removably positioned at least partially within a lumen of the elongated hollow shaft. The device also includes a second attachment mechanism coupled to the rod between the proximal end of the rod and the distal end of the rod. The first attachment mechanism and the second attachment mechanism are configured to be removably coupled to one another. The device also includes a cap configured to be removably coupled to the second attachment mechanism.

A device for correcting a compression-type fracture including a housing at a proximal end of the device, a cannula extending from the housing and through a directional balloon, and a tip at a distal end of the cannula, wherein the cannula has an outer tube for supplying fluid to the balloon and an inner tube positioned within the outer tube for supplying cement through at least one opening in the distal end of the cannula. A method of using the device where the device is inserted into a fracture site, the balloon is inflated to elevate fragments of the fracture, cement is injected into the opening created by elevating the fragments of the fracture and the device is removed from the fracture site. The balloon may be deflated before the injection of the cement or simultaneous with the injection of the cement.
