Biologic preparation and delivery system
A medical compound preparation and delivery system, including a delivery device, the device including a depressible trigger operably coupled to move a plunger; a cartridge releasably coupled to the delivery device, the cartridge defining a lumen therethrough to receive at least a portion of the plunger therein; a receptacle defining a cavity therein for receiving a medical compound; a first tube slidably positionable within the cavity of the receptacle; and a second tube slidably positionable within the first tube, wherein the cartridge is slidably positionable within the second tube.
BONE CEMENT PRESSURISER
A bone cement pressuriser (50) comprising a pressuriser head. The pressuriser head has a first side (51) coupled to or configured to couple to an end of a pressuriser handle and a second side (52) configured to transfer pressure to bone cement in a bone cavity. The second side of the pressuriser head is defined by a first, convex curved surface (53) and a second surface (54) forming a ring surrounding the first surface and extending radially beyond the first surface. A method of pressurising bone cement using the bone cement pressuriser is also disclosed. The first surface is configured to pressurise bone cement within a bone cavity and the second surface is configured to both pressurise bone cement within the bone cavity and to seal about the periphery of the bone cavity.
Systems and methods for off-axis augmentation of a vertebral body
Systems and methods for augmenting a vertebral body. An introducer device includes a shaft having a flexible distal portion with a pre-set curve in an unconstrained state. An input provided to an actuator to tension a pulling element to move the pre-set curve to a constrained state in which the distal portion and a flexible sheath conforming to the shaft at least partially straighten. The introducer device is removable from the sheath remaining offset from a longitudinal axis. A spacer hub facilitates proximal movement of the sheath relative to an access cannula expose a balloon through a syringe-style input. A hub of the access cannula may be adjustable to selectively adjust an interference surface relative to a datum. At least two radiopaque markers may be disposed on the sheath with relative positions between the markers viewable on lateral and A-P radiography to determine the location and/or curvature of the sheath.
Systems and methods for vertebral or other bone structure height restoration and stabilization
A system for stabilizing a bone structure. The system includes a guide device and an overlying delivery tube. A distal portion of the guide device is positionable within the bone structure and operable in a straight configuration and a curved configuration relative to a longitudinal axis. The overlying delivery tube comprises flexible polymeric material. The flexible polymeric material facilitates the delivery tube assuming a curve within the bone structure relative to the longitudinal axis when the guide device is in the curved configuration. The flexible polymeric material maintains a patent lumen along the curve when the guide device is withdrawn. The system may include an access cannula configured to penetrate the bone structure, and/or an expandable member insertable through the patent lumen along the curve. A delivery device may deliver curable material through the patent lumen along the curve to a target site within the bone structure.
METHODS AND DEVICES FOR DELIVERING MEDICAL MATERIAL
Methods and apparatuses for preparing and delivering medical material are disclosed. A material delivery apparatus includes a sheath that defines a lumen therethrough, a trough having an inner surface that defines a material receptacle, the trough being configured to slidably pass into the lumen, and a stylet configured to slidably pass into the material receptacle. The shape of the stylet complements the inner surface of the trough and a portion of the lumen when the trough is in the lumen of the sheath.
BONE CEMENT INJECTION DEVICE
The bone cement injection device includes an injection assembly and a filler assembly. The injection assembly includes a barrel, first needle member, second needle member, and plunger. The first needle member is movably housed inside the barrel, and includes a first member body, a first conduit, a side tube, and puller elements. The second needle member is housed in the first needle member, and includes a second member body, and a second conduit. A space is maintained between the first and second conduits. The plunger is joined to the first member body and is movably housed in the second member body. The filler assembly fills bone cement into the second member body. The first needle member is pulled backward, and the plunger injects the bone cement into the patient's bone. With an air compressor connected to the side tube, a negative pressure is created to facilitate bone cement injection.
Systems for augmenting of a vertebral body by providing for relative movement of a deformable conduit
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.
BONE GRAFT DELIVERY DEVICES, SYSTEMS AND KITS
A bone graft delivery kit includes a hollow tube having a proximal end and a distal end. The hollow tube is configured to convey graft material to a graft receiving area in a patient. The hollow tube can be connected to an implant. The kit further includes a plunger to facilitate moving the graft material through the hollow tube.
KYPHOPLASTY SYSTEM AND METHOD
A kyphoplasty system includes various instruments which can be selectively used in a surgical theater (e.g., during a surgical operation on a patient) or a surgical training environment. The kyphoplasty system can include one or more of a kyphoplasty apparatus, a prone table mat, a connector system, a bone introducer needle, and a biopsy device. The kyphoplasty system may also include a training system for use in the training environment.
