摘要： Devices, kits, and methods are provided for treating a bone structure, e.g., a vertebra, with a compression fracture. Wedges can be introduced into the bone structure in a direction that is lateral to the compression fracture, and stacked on tope of each to apply forces to the bone structure to reduce the compression fracture. The wedges can be introduced into the bone structure using a cannula. The wedges can be introduced as wedge pairs, in which case, a subsequent wedge pair can be introduced between a previously introduced wedge pair in order to drive the previously introduced wedges apart to create the stacking arrangement. Optionally, the wedges can be provided with longitudinal bores, in which case, they can be introduced into the bone structure, over a guide member that is threaded through the bores.

摘要： Devices and methods for the controlled delivery of therapeutic agents into bone and soft tissue to prevent the unintentional migration of therapeutic agents from the treatment site. The containment device can be made of a fabric or membrane that is porous, semi-porous, non-porous, bio-resorbable, or non-resorbable materials. A containment device is advanced to the interior of the target structure and filled with a therapeutic agent. The containment device may be permanently or temporarily implanted. Where permanent implantation is desired, the containment device may be detached via a severable junction.

摘要： Apparatus for delivering a media to an anatomic void within a bone structure and compacting the media within the anatomic void includes a delivery device and a compaction device. The delivery device includes a tubular element, a guidewire, and a removal element. The removal element is capable of forming a void at a target site within the bone structure by cutting and/or deforming target bone tissue. A distal end of the guidewire may be detachable as a safety feature. The compaction device includes an elongate member and a vibration device connected to the proximal end of the elongate member. The vibration device creates vibration at the distal end of the elongate member, so that the media is mixed and/or compacted within the anatomic void.

摘要： A device for accessing the spinal canal of a patient includes an introducer and a protective sleeve that is attached at one end thereof to a proximal end of the introducer. The protective sleeve has an outer stationary portion and an inner moveable portion. The outer and inner portions of the protective sleeve are separated by a crown region. A catheter is disposed inside the protective sleeve. During operation, the protective sleeve is advanced within the spinal canal to form a protective barrier between the catheter and the spinal cord. The catheter is advanced and retracted within the protective sleeve.

摘要： Tissue removal probes comprise an elongated member, a drive shaft rotatably disposed within the member, and a rotatable tissue removal element mounted to the distal end of the drive shaft. One tissue removal element comprises a plurality of tissue-cutting filaments affixed at proximal and distal ends of the tissue removal element. The cutting filaments may have optional hinge points that allow the distal end of the tissue removal element to be inverted, thereby transforming the tissue removal element from a tissue-cutting device to a tissue-grasping device. Another tissue removal element may have a blunted tip to prevent distal tissue trauma and an irrigation port to provide irrigation fluid to the removed tissue and/or tissue removal element. Another tissue removal element has a proximal and distal spiral grooves that are oppositely pitched, so that removed tissue can be collected in the middle of the tissue removal element.

摘要： Cannulas are provided for delivering therapeutic material to a treatment site. The cannula includes a cannula body with a plurality of openings at the distal end, including a longitudinal opening and a plurality of transverse openings that are axially spaced from each other. The cannula also includes a plunger that is configured to be slidably disposed within the cannula lumen. When the plunger is proximally displaced in the cannula lumen, the plunger seals the distal end and deflects the therapeutic material out the transverse openings. As the plunger is proximally displaced within the lumen, the therapeutic material is forced to perfuse out transverse openings located proximal of the plunger position. In one embodiment, the plunger includes an additional pliable sealable member. In another embodiment, the distal end of the cannula body may be implanted by separating the distal end from the cannula body.
