Disclosed is a medical device (9) comprising a porous structure (1), wherein a configuration of the porous structure (1) varies in dependence on a load applied to the porous structure (1), such that the porous structure (1) has a first configuration when the load is of a first magnitude, and has a second configuration when the load is of a second magnitude greater than the first magnitude. The porous structure (1) comprises a first surface portion (2) and a second surface portion (3). The first surface portion (2) is disengaged from the second surface portion (3) when the porous structure (1) has the first configuration, and is engaged with the second surface (3) portion when the porous structure (1) has the second configuration.

The present invention is directed to methods for collecting and processing autografts, processed autografts, kits for collecting and transporting autografts, and tools for preparing autografts. It is also directed to autologous bone grafts, and methods of preparing them.

The present invention relates to an assembly for imaging and/or treating brain tissue, having at least one acoustic window (10) which comprises a plate (1) that is transparent to ultrasonic waves, and at least one positioning marker (2) which facilitates positioning of a probe for generating ultrasonic waves so as to be aligned with said acoustic window (10).

Disclosed herein are patient-specific facial or craniofacial implants structured for filling bone voids in the cranium and face as well as for simultaneously providing soft tissue reconstruction and/or augmentation for improved aesthetic symmetry and appearance of face and skull. Pterional or temporal voids or defects generally result from a chronic skull or lateral facial deformity along with a compromised temporalis muscle or soft tissue distortion from previous surgery. When muscle atrophy occurs in the pterion or temporal face, temporal hollowing deformity generally results where there would be soft tissue but for the atrophy. The patient-specific temporal implants with dual-purpose herein are configured to have an augmented region adjacent the temporal region of the face and cranium in order to prevent and/or correct any such temporal hollowing deformity.

Provided are biocompatible and implantable scaffolds for treating a tissue defect, such as a bone gap. The scaffolds can have a modular design comprising a tissue scaffold rack designed to accommodate one or more modules. Also provided are methods for fabrication and use of such scaffolds.

Provided are porous, biocompatible implant bodies and materials. These materials suitably comprise a population of randomly arranged and entangled thermoplastic constituents, with at least some of the constituents being bonded to one another. The implant bodies are capable of being manipulated at room temperature from a first shape to a second shape, and of maintaining the second shape at about internal body temperature. Also provided are related methods of fabricating such implants and installing the implants into a subject.

Methods, devices and systems for virtual, remote and real-time collaboration between surgeons and engineers using system learning and intelligent and timely disbursement of design and performance information to engineering teams embarking on the preliminary design event of a personalized orthopaedic implant or personalize surgical instrument utilizing a case-based reasoning expert system. Additive manufacturing technology and statistically controlled advanced manufacturing processes quickly produce personalized medical devices worldwide.

To allow an implantable device including an electronic circuit to be implanted in the head in a more preferable manner in terms of appearance and safely. This implantable device is used for a brain-machine interface or the like. A casing of an implantable device configured to be implanted in a human head has an outer convexity surface matching an external shape of a resected skull related to at least a craniotomy site of the artificial bone designed in accordance with a skull shape of each person in order to fill the craniotomy site. That is, the outer convexity surface of the artificial bone is provided with two functions: the original function of filling the craniotomy site as the artificial bone and a function of serving as the casing of the implantable device.

Methods and systems for providing feedback to guide selection of an artificial bone flap. A user interface for planning a neurosurgical procedure is provided, the neurosurgical procedure including closing of an opening in a portion of a patient's skull using an artificial bone flap. 3D dimensions of the opening are determined using at least pre-operative three-dimensional (3D) imaging data. One or more parameters for selecting an artificial bone flap are determined, where the one or more parameters are based on at least the 3D dimensions of the opening. Output indicating one or more recommended available artificial bone flaps suitable for closing the opening is provided, the recommendation being based on the determined one or more parameters.

A surgical implant, which in use, provides a barrier between layers of tissue such that tissue on one side of the implant does not adhere to tissue on the other side, the improvement comprising that the implant is made of suitably anatomically shaped surgically acceptable sheet material.
