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.

System for use in treatment of vertebral fractures

Steerable medical delivery devices that have a steerable portion and an external controller. The steerable portion has a first tubular member comprising a flexible polymeric tubular member that comprises a wall of solid material along the steerable portion, the first tubular member configured to preferentially bend, and a second tubular member, wherein one of the first and second tubular members is disposed within the other, wherein the first and second tubular members are permanently axially fixed relative to one another at a fixation location distal to the steerable portion.

Steerable delivery sheaths

Apparatus and methods for bone fracture repair. The apparatus may include a structural support for positioning a first bone segment relative to a second bone segment. The apparatus may include an anchoring substrate. The anchoring substrate may be configured to compress the first bone segment to the second bone segment. The anchoring substrate may transmit tension from a distal bone segment anchor in the first bone segment to a proximal bone segment anchor in the second bone segment. The apparatus may be configured to be deployed percutaneously in an inner cavity of a bone. The apparatus may be installed in an open fracture. The apparatus may be expanded, self-expanding or configured for mechanically actuation. Some embodiments of the apparatus may include a central axis member that may be used in conjunction with expansion of one or both of the structural support and the anchoring substrate to configure the apparatus.

Apparatus and methods for fracture repair

A modular catheter system including a sheath projecting distally from a delivery catheter having a main body module An inner core module carrying a stent thereon, the inner core being axially movable through the main body of the delivery catheter and the delivery catheter sheath, a handle member supported by the main body of the delivery catheter, the handle member being selectively axially engageable with the inner core such that the handle member and the inner core move together in an axial direction when the handle member is engaged with the inner core; and an adjustment member supported by the main body, the adjustment member being configured such that rotation of the adjustment member causes the adjustment member to move axially along the main body by either axially sliding the handle member relative to the main body or by rotating the adjustment member.

Systems for treating a vertebral body

The invention relates to devices and methods for creating a curvilinear cavity within a vertebral body or other body structure. An example method of forming a void in bony structure includes accessing a bony structure with a cannula, inserting a distal end of a combined drill and reaming device through the cannula and into the bony structure, manipulating the distal end of the combined drill and reaming device to create a void in the bony structure, and removing the distal end of the combined drill and reaming device from the cannula.

Devices and Methods for Vertebrostenting

A surgical clip applicator includes a handle configured to produce translational movement; a cartridge containing a plurality of clips arranged in a row, the cartridge including a jaw assembly for receiving and closing a clip; a jaw closing mechanism for closing the jaw assembly; a clip feed mechanism for serially feeding a lead clip from the row to the jaw assembly; a clip advance mechanism for advancing the row as the lead clip is fed to the jaws; and a rocker mechanism for translating translational movement from the handle opposite translational movement of the haw closing mechanism in one direction and the clip feed mechanism and clip advance mechanism in an opposite direction

Surgical clip applicator

A rod cutter apparatus includes a rod holding plate having a rod opening for receiving a rod to be cut; a cutting member having a central opening defined by a cutting edge, the central opening being substantially aligned with the rod opening; and a drive assembly connected between the rod holding plate and the cutting member to cause oscillation of the cutting member relative to the rod holding plate, wherein oscillation of the cutting member relative to the rod holding plate cuts a rod in the rod opening.
