摘要： Disclosed are products and methods for delivery of a material to an internal body part such as bone. In one variation, the product includes an access member having a side port aperture positioned near the distal end of the access member for extruding a material to a body part within a subject, wherein the access member comprises a variation in the internal diameter adjacent to the side port aperture, and wherein the variation in the internal volume adjacent to the side port aperture reduces the tendency of the material extruded from the side port to adhere to the material remaining in the access member.

摘要： Apparatuses and methods for performing minimally invasive medical procedures are disclosed herein. In one example, an apparatus includes an elongate body that has a deformable distal portion and defines a lumen, the lumen extends through the deformable distal portion. The deformable distal portion has a cutting portion and defines an opening. The elongate body has a first configuration in which the opening is a first size and a second configuration in which the opening is a second size smaller than the first size of the opening. The elongate body in the first configuration is configured to be percutaneously inserted at least partially into a tissue such that at least a portion of the tissue is disposed within the lumen. The elongate body is configured to move to the second configuration when the elongate body reaches a threshold temperature while inserted in the tissue.

摘要： Devices and methods are provided for treating a bone structure (such as, e.g., reducing a bone fracture, e.g., a vertebral compression fracture, or stabilizing adjacent bone structure, e.g., vertebrae) is provided. The device comprises rigid or semi-rigid members, each of which comprises a common base and a plurality of ribs that extent along the a longitudinal portion of the common base. The device is configured to be placed in a collapsed state by engaging the pluralities of ribs of the members in an interposed arrangement, and configured to be placed in a deployed state by disengaging the pluralities of ribs. The ribs can be any shape, e.g., flutes, that allows opposing ribs to intermesh with one another. In this manner, the device has a relatively small profile when placed in the collapsed state, so that it can be introduced through small openings within the bone structure, while preserving the shear strength of the members during deployment of the device.

摘要： Devices, kits, and methods are provided for reducing a bone fracture, e.g., a vertebral compression fracture, is provided. The device comprises a plurality of resilient wires composed of a biocompatible material, such as a biocompatible polymer (e.g., polymethylmethacrylate (PMMA)). The wires can be introduced into the cavity of the bone structure to form a web-like arrangement therein. The web-like arrangement can be stabilized by applying uncured bone cement onto the arrangement to connect the wires at their contacts point. The bone cavity can then be filled with a bone growth enhancing medium.

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： A guidewire for use with a catheter has varying radiopacity as well as at least one radiopaque marker in its distal end. In one embodiment, the guidewire includes a shaft that supports a distal radiopaque coil and a proximal radiopaque coil. The proximal and distal coils are spaced apart from one another. The non-radiopaque area between the two coils has at least one radiopaque marker band attached to the shaft. The marker bands provide several radiographically visible reference Lengths. A polymer sleeve encases the marker bands and the shaft between the first and second coils providing a uniform outer diameter to the distal region of the guidewire. In another embodiment, the proximal coil may be omitted. In a further embodiment, a radiopaque coil having varying pitch along its length is supported by and attached to a distal region of the core wire. The coil includes highly radiopaque distal and proximal sections, or highly radiopaque distal section and lightly radiopaque window section, and a more moderately radiopaque intermediate section. The intermediate section of the coil may include at least one smaller tightly wound radiographically dark coil section separated from the distal and proximal sections and from one another by loosely wound coil sections. A polymer sleeve is attached to the guidewire and covers a portion of the coil. In a fourth embodiment, the sleeve is attached to the guidewire only at its ends and covers the intermediate window section of the coil.
