An implant may include a curved implant body and a flange extending from the implant body, the flange being thinner than the implant body, the implant body and the flange having a first exterior surface and a second exterior surface opposite the first surface in which the implant body and the flange formed by at least partially fused particles. The particles at the first surface define a first average pore size and the particles at the second surface define a second average pore size; with the first average pore size being greater than the second average pore size. The first surface may be a tissue ingrowth surface and the second surface may be a tissue ingrowth barrier.

An implant suitable for being anchored with the aid of mechanical vibration in an opening provided in bone tissue. The implant is compressible in the direction of a compression axis under local enlargement of a distance between a peripheral implant surface and the compression axis. The implant includes a coupling-in face which serves for coupling a compressing force and the mechanical vibrations into the implant, which coupling-in face is not parallel to the compression axis. The implant also includes a thermoplastic material which, in areas of the local distance enlargement, forms at least a part of the peripheral surface of the implant.

A device for modulating biological tissue and/or bone conformation, the device including a shape memory material and being capable of modulating biological tissue and/or bone conformation simultaneously in at least two dimensions, a process for producing the device, a process for modulating biological tissue and/or bone using the device, and uses thereof.

Injectable bone graft material having a biocompatible, resorbable polymer and a biocompatible, resorbable inorganic material exhibiting macro, meso, and microporosities.

A burr hole cover includes a cap or cap assembly and a retainer and is configured to be partially positioned within a burr hole formed in a patient. The retainer has a cap-receiving aperture; a plurality of grooves provided in the retainer and a plurality of cut-outs wherein each cut-out is provided at an end of each groove towards the outer perimeter of the retainer. A channel may be provided at an opposite end of each groove vertically-extending from the top to the bottom of the retainer to encourage a medical device segment to remain in a groove during installation of the burr hole cover. The burr hole cover may be used to secure segments of medical devices relative to a burr hole and to allow a range of lateral motion for the portion(s) of the medical device(s) extending proximally out of the corresponding groove.

Provided is a surgical method. The method includes detecting a location of a reference unit having a trackable element with a detector, the detector configured to provide at least one signal corresponding to a detected location of at least the reference unit's trackable element, wherein the reference unit is associated with a location of an anatomical feature of a being's anatomy; accessing a computer-readable reconstruction of the being's anatomy, the computer-readable reconstruction of the being's anatomy having a first updatable orientation, wherein the first updatable orientation is updated in response to the at least one signal; accessing a computer-readable reconstruction of an implant having a second updatable orientation; detecting a location of a pointer tool comprising a trackable element with the detector, the detector further configured to provide at least one other signal corresponding to a detected location of at least the pointer tool, wherein the pointer tool is associated with a location of an anatomical feature of interest; accessing at least one computer-readable reconstruction of a trace, the trace corresponding to a geometry of the anatomical feature of interest based on updated detected locations of the pointer tool; superimposing the at least one updatable, computer-readable trace on the second computer-readable reconstruction of the implant.

A cranial plate is provided for use after a craniectomy. The plate is mounted to the skull and protects the brain exposed in the skull opening. A plate is initially spaced above the skull with gaskets or spacers so as to preclude pressure on the brain. The gaskets or spacers are resorptive, or otherwise dissolve or shrink over time, until the plate settles upon the skull. An elastic web extending over the plate provides a constant force to pull the plate towards the skull as the spacers shrink. The plate is secured to the skull using screws. The plate may include alignment posts residing adjacent the skull opening to maintain proper positioning of the plate as the spacers shrink. The plate eliminates the need for a second cranioplasty surgical procedure.

A special tube is disclosed for the insertion of materials inside the maxillary sinus in order to displace the Schneiderian membrane. The tube is connected to a source of a flowable material. The tube is inserted through the alveolar ridge beneath the maxillary sinus and when the flowable material is advanced through the tube the Schneiderian membrane is lifted. The tube can be part of a dental implant which is screwed inside the alveolar ridge.

An implant, such as a cranial implant, for attachment to a defect in a bone structure having an edge is described. The implant comprises a direction of extension and a rim extending substantially perpendicular to the direction of extension of the implant. The rim is configured to be attached to the edge of the bone structure and comprises at least one mounting portion (6) configured to accommodate a fastener such that at least a portion of the fastener is extendible in a direction extending away from the rim at an angle which is at most acute with respect to the direction of extension of the implant. The implant is configured such that upon placing the implant in the defect, the fastener is extendible into the edge of the bone defect in a controllable manner.

A mosaic implant (2010) comprises a mesh support frame comprising a plurality of polygonal support rings (2040 A, B, C) connected by a plurality of struts (2014), and a plurality of mosaic plates (2012). The support rings are positioned within the mosaic plates; the struts extend between adjacent plates. An implant (1510) for filling a bore hole comprises a plate (1512) and a support frame (1520) having a central portion (1522) located at least partially within the plate, a polygonal outer rim (1524) having a plurality of fastening points for attaching the implant to bone surrounding a bore hole, and a plurality of arms (1530) extending between the central portion and the outer rim. The plurality of arms extend inwardly and downwardly away from the outer rim such that the central portion is located below the plane of the outer rim and the upper surface of the plate is flush with or slightly above the upper surface of the outer rim.
