EXPANDABLE INTERVERTEBRAL IMPLANT

An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

The proximal end having a first opening and the distal end having a second opening. The first opening and the second opening configured to slidably receive at least a portion of a plunger. A locking member is provided that is pivotably connected to an upper surface of the housing and extends adjacent to the upper surface of the housing. The locking member comprises a locking surface extending adjacent to the distal end of the housing configured to engage a portion of a tubular member, a funnel, or a combination thereof. The locking member is movable in a locking position to lock the portion of the tubular member, the funnel, or the combination thereof with the housing. A bone material dispensing system and a method of implanting bone material with the bone material dispensing system are also provided.

HARVESTING CANCELLOUS BONE AND MARROW FROM DISTAL FEMUR, PROXIMAL TIBIA, DISTAL TIBIA, OR CALCANEUS USING BONE PRESS APPARATUS
20230139232 · 2023-05-04 ·

Methods of harvesting cancellous bone and bone marrow include extracting loosened cancellous bone and bone marrow—including a liquid component thereof—to a collection container that has a first cup and a suction port to which a suction source is connected. After extraction, the suction source is disconnected and a lid of the collection container is removed and replaced with a lid having a plunger with a press head that is configured to filter the extracted liquid by depressing the plunger toward a bottom of the first cup. The filtered liquid is poured through a suction port into a second cup while depressing the plunger, thereby separating the liquid from a semi-solid mass of cancellous bone that remains. The bone is extracted through a cortical opening in the femur, tibia, or calcaneus, or from an intermedullary canal that is preferably formed by reaming of the tibia using an orthopedic reamer.

ELBOW PROSTHESIS

An elbow prosthesis according to the present teachings can include a stem structure and an articulating component. The stem structure can be operable to be positioned in a bone of a joint. The stem structure can include a stem portion that is operable to be positioned in the bone and a C-shaped body portion having a first retaining mechanism formed thereon. The articulating component can have a second retaining mechanism formed thereon. One of the first and second retaining mechanisms can comprise an extension portion and a first anti-rotation portion. The other retaining mechanism can comprise a receiving portion and a second anti-rotation portion. The articulating component can be advanced from an insertion position to an assembled position, such that the first and second mechanisms cooperatively interlock to inhibit translation and rotation of the articulating component relative to the C-shaped body portion of the stem structure.

ELBOW PROSTHESIS

An elbow prosthesis includes a stem structure and an articulating component. The stem structure is operable to be positioned in a bone of a joint and includes a stem portion and a C-shaped body portion. The stem portion is operable to be positioned in the bone. The C-shaped body portion includes a first articulating surface bound by a medial wall and a lateral wall. The medial and lateral walls are separated by a first distance. The articulating component includes a second articulating surface positioned between a medial side surface and a lateral side surface. The medial and lateral side surfaces are separated by a second distance that is less than the first distance. The second articulating surface is configured to slidably communicate in a medial/lateral direction along the first articulating surface of the C-shaped body portion.

SURGICAL REAMER DEVICE AND METHOD OF USING SAME
20230190307 · 2023-06-22 ·

Embodiments of a reamer device for removing tissue from a patient, including a shaft, a cutting head having at least four cutting blades, and a depth-limiting flange extending radially outwardly away from the at least four cutting blades. Some embodiments of the reamer device can have a shaft, a cutting head coupled with the shaft, and a depth limiting element. The cutting head can have at least four cutting blades. In some embodiments, the depth limiting element can have a distal surface configured to contact a surface of the patient's tissue to limit a depth into the patient's tissue that the at least four cutting blades can advance to, and/or can be configured to extend radially outwardly of the at least four cutting blades so that the depth limiting element contacts a surface of the patient's tissue adjacent to a cutout created by the at least four cutting blades.

Bone Graft Cage

A device for containing bone graft material includes an outer sleeve including a first proximal longitudinal split extending along a length thereof and a first distal longitudinal split extending along a length thereof and an inner sleeve connected to the outer sleeve via at least one strut so that a bone graft collecting space is defined therebetween, the inner sleeve including a second distal longitudinal split extending along a length thereof in combination with an interstitial mesh extending circumferentially between the inner and outer sleeves to hold graft material in the bone graft collecting space, the interstitial mesh including a third longitudinal split extending along a length thereof so that a distal side of the device may be spread open to open the distal longitudinal slot from the outer sleeve, through the interstitial mesh and the inner sleeve to a space radially within the inner sleeve.

Remotely-activated vertebroplasty injection device

A remotely-activated injection device for use in vertebroplasty is provided to inject a flourescent probe material into a patient. The injection device includes a pump defining an injection chamber having an exit opening; an actuator; and a cable having a first end coupled to the actuator, and a second end remotely engaging the pump. The actuator remotely controls the pump by responsive movement of the cable to thereby cause injection of a flourescent probe material from the injection chamber of the pump through the exit opening to the patient.

A bone graft loading device includes a syringe comprising a nozzle at a distal portion of the syringe and an opening at a proximal portion of the syringe, and a plunger configured to force bone graft material from the reservoir through the nozzle. The plunger comprises a plunger body positioned at least partially within the syringe and defining a lumen. A tamp is positioned within the lumen of the plunger body and is configured to protrude distally of the plunger through the nozzle. The plunger mates with an inner wall of the syringe and the tamp to block passage of the bone graft material into the lumen of the plunger body. The plunger can be rotated to guide the bone graft material into the cannula, and the tamp can be periodically actuated to clear clogs that form at or near the nozzle.
