摘要:
Systems and methods for treating vertebral compression fractures are discussed. In an embodiment, a method includes mixing bone cement precursors thereby causing a first chemical curing reaction characterized by a first time-viscosity profile, controllably applying energy to the bone cement from an external source to modify the first time-viscosity profile to a second time-viscosity profile, and injecting the cement into bone at a substantially constant viscosity greater than about 1000 Pa·s to greater than about 5000 Pa·s over an extended working time. In another embodiment, a bone cement injector system is provided that includes a first handle component that is detachably coupled to a second sleeve component having a distal end for positioning in bone and a flow channel extending through the first and second components. The system includes first and second thermal energy emitters for delivering energy to bone cement flows in a flow channel portion in the first and second components, respectively.

Methods for producing a composite bone graft material that can regenerate bony defects in the body are provided. Also, methods, kits and delivery systems for a minimally invasive delivery of a composition for regenerating bone at or near the site of a bony defect that include, the composition for regenerating bone comprising collagen and bioactive glass are provided.
摘要:
The present invention relates to a medical instrument which comprises a tool portion with a first tool element for engagement with a corresponding second tool element on an implant, and which further comprises a bone cement container arranged or formed on or in the instrument.
摘要:
A non-compliant medical balloon may be changed from a deflated state to an inflated state by increasing pressure within the balloon. The non-compliant medical balloon is composed of a woven fabric layer composed of at least two woven fabric fibers forming an angle. The angle remains substantially unchanged when the balloon changes from a deflated state to an inflated state.
摘要:
A method of treating a vertebra, comprising: (a) accessing an interior of a vertebra; and (b) introducing a sufficient amount of artificial biocompatible material which does not set to a hardened condition in storage, into said bone, with sufficient force to move apart fractured portions of said bone.

An apparatus for the delivery of a biological composite and a method, kit, and system for preparing a biological composite is described herein. The biological composite includes both inorganic and biological materials.
摘要:
A method of delivering graft material to a surgical site includes positioning graft material in a tube of a delivery device. The tube defines an open end and a bend along its length. A plunger within the tube is advanced to dispense the graft material through the open end.
摘要:
Devices and method discussed for device for delivering a pressurized substance to an opening in bone within a vertebral column, useful to provide access to structures in the vertebral so that a substance, such as bone cement can be delivered through a lumen or portal or for providing access to the opening in bone by a separate instrument.
摘要:
An apparatus and methods for delivery of reinforcing materials to a weakened or fractured bone is disclosed. An apparatus for delivering a reinforcing mixture to a bone including a tube having a proximal end, a distal end, and a longitudinal axis therebetween, wherein the tube has at least one inner lumen capable of allowing a bone reinforcing mixture to pass therethrough; a balloon engaging the tube wherein the balloon expands from a substantially deflated state to a substantially inflated state upon the bone reinforcing mixture entering the balloon; and at least one light guide extending through the tube into the balloon to guide a light into the balloon.
摘要:
The present invention relates to an apparatus and method for near-simultaneous and integrated delivery of bone graft material during the 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 selectably detach the fusion cage for deposit to the same disc space. 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.
