摘要:
A device for forming expansion regions in a bone, comprising, an elongate body having and axis and adapted to fit through a tunnel in a bone; and a head, provided on said body and having outer dimensions not substantially extending trans-axially to said body, wherein said head is rotatable and wherein said head is adapted to widen said tunnel in said bone by at least 10% in conjunction with said rotating.
摘要:
A hip plate, comprising: a plate body adapted to be attached to a femur or other bone; and at least one lag screw adapted for insertion into a femoral head or other bone protrusion and rotationally lockable to said plate.
摘要:
A method of treating a vertebra, comprising: (a) accessing an interior of a vertebra; and (b) introducing a sufficient amount of artificial biocompatible material which does not set to a hardened condition in storage, into said bone, with sufficient force to move apart fractured portions of said bone.
摘要:
A polymeric liner for joint implants includes at least one friction reducing member and at least one body member. The friction reducing member is made of a polymeric matrix which contains a polymeric material and at least one nanotube nanoparticle having a volume concentration of between 5%-99% v/v (volume per volume). The body member is formed of at least a polymeric material. The friction reducing member and the body member are conjoined preferably by compression molding or any other method of coupling such as mold injection, 3D printing, adhesion or any other suitable method can be applied. A method produces the polymeric.

摘要:
A bone cement comprising a first component and a second component, wherein contacting the first component and the second component produces a mixture which attains a high viscosity an initial period and the viscosity of the mixture remains relatively stable for a working time of at least 5 minutes after the initial setting period, and the mixture is suitable for in-vivo use.
摘要:
Apparatus and methods are provided including identifying a subject as suffering from a disorder of an organ of the subject. In response to the identifying, a shaft is inserted into the organ, not via a natural lumen of the subject. Using a laser beam emitted from a distal portion of the shaft, a portion of the organ is ablated. A vicinity of the portion of the organ is cooled by introducing a fluid to the vicinity, and, subsequently aspirating the fluid therefrom, the introduction and aspiration of the fluid being performed via the shaft, while the shaft is inside the organ. Other embodiments are also described.

摘要:
An uncoated polymeric liner for a medical joint implant constructed to be engaged in between a head (or a top plate) and a stem (or a base plate) of said medical joint implant. The uncoated polymeric liner is prepared from a polymeric matrix comprising a polymeric material and at least one metal chalcogenides or dichalcogenides nanoparticle which is distributed within said polymeric matrix.
摘要:
An expandable spacer, comprising: an axial tube having a surface, a proximal end and a distal end and a length, wherein, said surface defines a plurality of slits, said plurality of slits defining at least two axially displaced extensions, such that when said tube is axially compressed, said extensions extend out of said surface and define a geometry of an expanded spacer. Preferably the spacer is adapted to be inserted between two spinal vertebrae of a human.
