Apparatus and methods for treatment of a bone. The apparatus may include an implant. The implant may include an implant tail and an implant head configured to expand, inside the bone, from a collapsed state to an expanded state. The apparatus may include an intramedullary rod defining a central longitudinal rod axis. The intramedullary rod may include a guide segment configured to guide the implant head into the bone and support the implant tail. The intramedullary rod may include an elongated extension member spaced radially apart from the central longitudinal axis. The extension member may be configured to provide clearance for the implant head as the implant head is advanced, in the collapsed state, into the bone. The extension member may be configured to provide clearance for the implant head in the expanded state.

Apparatus and methods for treatment of a bone

Apparatus and methods for bone cavity preparation. Formed broaching members may be supported inside a bone by a rotator. The broaching members may be bowed out inside the bone to create a cavity having a shape determined by the broaching members and bone anatomy.

Tissue displacement tools and methods

Apparatus and methods for securing a bone implant are provided. The implant may be an expandable implant. The implant may be a non-expandable implant. The implant may be for repairing a bone fracture. The implant may be secured to a bone by anchors. The implant may include anchor receiving features. The anchor receiving features may be configured to direct an anchor into cortical bone. The anchor receiving features may be configured to receive an anchor driven through cortical bone. The implant may include bone engaging members configured to engage cancellous bone. An implant may include different profiles. The different profiles may be configured to secure the implant. The profiles may be configured to support the bone. The implant may have different flexing properties configured to position the implant in the bone. The implant may be positioned to receive an anchor driven through an outside of the bone.

Apparatus and methods for securing a bone implant

Apparatus and methods for preparing the interior of a bone for therapy. The therapy may include therapy for a bone fracture. The apparatus and methods may involve orienting a surgical instrument for proper deployment in the interior of the bone. An instrument guide may be positioned and retained against translation along, and rotation about one or more of three substantially orthogonal axes. Apparatus placed exterior to the bone may register the guide to a region inside the bone that is designated for preparation or treatment. One or more broaching members may be used to prepare the region for treatment. A broaching member may be expandable inside the bone. A broaching member may be flexible such that it broaches bone having a relatively lower density and it leaves bone having a relatively higher density substantially intact.

Apparatus and methods for bone access and cavity preparation

Apparatus and methods for preparing a fractured bone for repair. Preparing the bone may include fracture reduction. Preparing the bone may include holding a fracture in reduction. Preparing the bone may include identifying locations for obtaining access to an interior region of the bone. The apparatus may include structures outside the bone that interact with fragments of the bone. The structures may participate in the reduction. The structures may participate in holding the reduction. The structures may participate in identifying the locations.

Apparatus and methods for bone repair preparation

A prosthetic heart valve includes an annular stent having annularly spaced commissure portions. The tips of the commissure portions are preferably covered with fabric, and then additional fabric covers that fabric and the remainder of the stent, both inside and out (possibly also including a sewing ring insert at or near the base or inflow edge). The fabric is then covered by a layer of tissue, again both inside and out. A single sheet of additional tissue is mounted around the outside of the previously assembled components. This additional tissue forms the leaflet portions of the valve. The leaflet portions of the additional tissue are shaped by contact with a shaped mandrel, and the tissue of the structure is subjected to fixation (e.g., cross-linking) to produce a completed valve.
