A prosthetic disc can take the form of a sensing artificial disc that includes a resilient core and at least one sensor configured to sense one or more conditions within and/or experienced by the disc. The sensing artificial disc can serve as a replacement to a failed or injured disc between two vertebrae of a spine. The sensing artificial disc can include at least one element configured to change a condition or property of the resilient core in response to a condition sensed by the at least one sensor. A prosthetic disc can include therapeutic system configured to deliver medication to the body, which can include a reservoir of medication.

Proposed is a hybrid ceramic prosthesis. Since the prosthesis is made of a novel hybrid ceramic material, the prothesis has a similar color and transmittance to natural teeth, minimizes tooth removal during preparation for placement of the prothesis, is securely attached to the target tooth by snap-fit fastening to prevent detachment of the prothesis and re-treatment caused by the prothesis detachment, and can be more conveniently applied to the patient than conventional prostheses, enabling an one-day-one-stop dental procedure, thereby reducing burden to patients. The prothesis is useful as a primary crown.

A fiber-based surgical implant stabilized against fraying, includes a thermally crimped flat-knitted fabric of a biocompatible, optionally biodegradable, polymer material having a glass transition temperature or other thermally induced secondary conformational mobility threshold in the temperature range of from 20° C. to +170° C. Also disclosed is a corresponding fabric and methods of producing the implant and the fabric.

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 knee replacement system for enabling natural knee movement in a leg comprising a prosthetic is provided. The prosthetic includes a tibial portion at least partially implantable on a resected surface of a tibia; a plate portion attached to the tibial portion and at least partially implantable in a meniscal space; wherein the plate portion comprises a top surface having a medial recess and a lateral recess and a bottom surface attached to a top surface of the tibial portion wherein the tibial portion and the plate portion are one piece, wherein a medial side surface, a lateral side surface, a posterior side surface and an anterior side surface are attached to at least a portion of the top surface and at least a portion of the bottom surface and defining a medial side edge, a lateral side edge, a posterior side edge and an anterior side edge respectively, where in at least a portion of one of the medial side edge, lateral side edge, posterior side edge, and anterior side edge is oblique.

The strength of bone implant attached to a bone is improved by using hybrid inserts which have stems and wings having bone ingrowth surface features and caps having outer surfaces of cured polymethyl methacrylate (PMMA). The stems and wings of the hybrid inserts are inserted into living bone and the bone implant is attached to the hybrid inserts with PMMA cement. Over time, the bone grows into the bone ingrowth surface features. The bone ingrowth strengthens the bonding of the hybrid inserts and the bone implant with the bone over time. The hybrid inserts increase the shear, tensile and torque strength of the bone implants. Bone inserts that do not have ingrowth surface features loosen over time.

A method for structuring a surface of an implant (100) made from a plastic material by means of a counter-body (200) comprises the following steps: providing (S110) of a counter-body (200) including a surface (210); forming (S120) of a first surface structure (212) on the surface (210) of the counter-body, wherein a first surface structure (212) comprises a non-regular, randomly distributed pattern; and forming (S130) of a second surface structure (112) on the implant (100) by using the counter-body (200), wherein the second surface structure and the first surface structure (212) are complementary to each other.

The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region is generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.

A perforated sheath is anchored in a tissue opening with the aid of a tool, wherein the anchorage is achieved with the aid of mechanical vibration and a material which is liquefiable by the vibration. The tool includes a vibrating element and a counter element. Distal portions of both elements are introduced into the sheath to be in contact with each other at an interface. The vibrating element is connected to a vibration source and the vibrating element and the counter element are held against each other for effecting liquefaction of the liquefiable material at the interface. Under the effect of the force applied to the vibrating and counter element for holding them against each other, the liquefied material flows from the interface through the sheath perforation and penetrates the tissue.

A method for implanting a medical device for implantation in a mammal joint. The method comprising the steps of creating an opening reaching from outside of the human body into the joint, providing said artificial contacting surface to said joint, fixating the artificial contacting surface to the joint, implanting said reservoir in the human body, and lubricating the artificial contacting surface with use of a lubricating fluid contained in said reservoir.
