In one aspect, an instrument for placing a graft, implant and/or graft material at a target site for enhancing posterolateral fusion between two or more vertebrae is provided which includes a housing and an actuable trigger associated with the housing. A curved rigid access tube extends from the housing, the access tube terminating at a distal end. A sheath is disposed about, and moveable relative to the access tube, and a transmission is disposed in the housing. In an initial state, the sheath extends distally past the distal end of the access tube, a space being defined within the sheath distally of the distal end of the access tube to accommodate the graft, implant and/or graft material. The transmission is configured to cause an incremental displacement of the sheath relative to the distal end of the access tube upon an actuation of the trigger.

A perforated sheath is anchored in a tissue opening with the aid of a tool, wherein the anchorage is achieved with the aid of mechanical vibration and a material which is liquefiable by the vibration. The tool includes a vibrating element and a counter element. Distal portions of both elements are introduced into the sheath to be in contact with each other at an interface. The vibrating element is connected to a vibration source and the vibrating element and the counter element are held against each other for effecting liquefaction of the liquefiable material at the interface. Under the effect of the force applied to the vibrating and counter element for holding them against each other, the liquefied material flows from the interface through the sheath perforation and penetrates the tissue.

Methods and devices that displace bone or other hard tissue to create a cavity in the tissue. Where such methods and devices rely on a driving mechanism for providing moving of the device to form a profile that improves displacement of the tissue. These methods and devices also allow for creating a path or cavity in bone for insertion of bone cement or other filler to treat a fracture or other condition in the bone. The features relating to the methods and devices described herein can be applied in any region of bone or hard tissue where the tissue or bone is displaced to define a bore or cavity instead of being extracted from the body such as during a drilling or ablation procedure.

The present disclosure relates to an apparatus and method for near-simultaneous and integrated delivery of bone graft material and placement of surgical cages or other medical implants in a patient's spine. The integrated fusion cage and graft delivery device according to various embodiments delivers and disperses biologic material through a fusion cage to a disc space and, without withdrawal from the surgical site, may detach the fusion cage for deposit. The integrated fusion cage and graft delivery device is formed such that a hollow tube and plunger selectively and controllably place bone graft material and a fusion cage in or adjacent to the bone graft receiving area. In certain embodiments, the integrated fusion cage is an expandable integrated fusion cage.

A combination of an implant (100) like a bone screw together with an augmentation sleeve (200) is suggested. The bone screw may comprise a trailing end portion with a plurality of lateral bores (120). The augmentation sleeve may comprise a leading end portion which is adapted to be coupled to the trailing end portion of the bone screw, and a lateral opening (220) at the leading end. The augmentation sleeve may be adapted to guide an augmentation tool to the trailing end portion of the bone screw and to the leading end portion of the augmentation sleeve so that the trailing end portion of the bone screw may be augmented by pressing augmentation material through the plurality of lateral bores at the trailing end portion of the bone screw and further through the lateral opening of the augmentation sleeve into the bone at the trailing end of the bone screw, or other implant. After the augmentation of the trailing end portion of the bone screw, the augmentation sleeve may be removed.

A portable and passive safety intraosseous device to allow for direct introduction of medications, etc., within the intermedullary space of a subject patient's bone or, if needed, the removal of certain substances from such a subject patient's bone. Such a device permits direct drilling and placement of a cannula within the subject bone with access external to the subject patient's skin, permitting, as well, connection of a tube for such introduction/removal purposes. The ability to provide a passive safety unit allows for facilitated utilization in, for instance, emergency situations with the entire device provided for utilization thereof. The device includes a drilling component with a permanently attached stylet and a removable cannula, a power supply for a single drilling operation, a mechanism to draw the stylet back into the drill component after use and disengagement from the cannula, and an automatic closure that activates with the separation of the cannula.

The present invention relates to an apparatus, system and method for delivery of bone graft material in a patient's spine. The graft delivery device according to various embodiments delivers and disperses biologic material to a disc space and without withdrawal from the surgical site. In various embodiments, the graft delivery device includes an elongate hollow tube configured to receive bone graft material, a plunger adapted to extend in the elongate hollow tube and urge the bone graft material through the elongate hollow tube, and an injection device (such as a syringe) configured to contain the bone graft material therein and to connect to an open proximal end of the elongate hollow tube, to discharge the bone graft material from the first injection device into the elongate hollow tube.

A bone anchor includes a shaft having a first end and a second end, a bore extending from the first end to the second end, and a plug member which is insertable into the bore and guidable through the bore for closing the bore at the second end. The bone anchor is suitable for minimally invasive surgery in such a way a guide wire can be guided through the bone anchor and after the bone anchor has been anchored in the bone the plug member is inserted to close the open end of the bone anchor. A bone cement or a pharmaceutical substance can be introduced into the bone anchor.
