Abstract: A hinged connection between first and second members (24, 25) which makes use of a fixation pin (1). The fixation pin (1) has a first configuration which enables the pin to be inserted through a first hole in a first member (24), through an aligned intermediate hole in the second member (25) and through an aligned second hole in the first member (24). The fixation pin (1) does not have a screw thread on its exterior surface. The fixation pin (1) after it has been inserted is subject to a treatment which changes it to a second configuration, or the fixation pin spontaneously changes, while it is being inserted through the holes or immediately thereafter, to a second configuration. In the second configuration, part or all of the fixation pin contacts the wall of at least one of the holes, so that the first and second members are connected together at a hinged connection.

Abstract: Devices comprising a component which has an open porous structure composed of an alloy of nickel and titanium or a mixture of nickel and titanium. The devices can be implanted in a mammalian body and provide desired interaction with protein, blood, ions, bone cells, and tissue. The devices are particularly useful for providing a substrate for the ingrowth of bone. In the open pore structure, preferably more than 95% of the pores having a size of 50-1000 ?m, particularly 50-600 ?m, with a pore size standard deviation of 250 ?m or less, particularly of 150 ?m or less, and an average porosity by volume of 40-80%. When the device is implanted adjacent to a cancellous bone, the porous component preferably has a modulus of 0.1-1.2 GPa. When the device is implanted adjacent to cortical bone, the porous component preferably has a modulus of 16 to 24 GPa. The devices are also useful for filtering a liquid.

Abstract: Eyeglass assemblies comprise (1) a shear pin which secures a frame member (1, 12) to a lens (11) or two frame members to each other, and/or (2) components which are substantially more transparent to ultraviolet radiation than the lens material, and/or (3) auxiliary members (14) which extend upwards from the lenses and facilitate correct positioning of the eyeglass assembly.

Abstract: An endoscopic surgical instrument for removing tissue or bone, the instrument comprising (1) a generally tubular component (2) a cutting device which is housed in the distal end member and part of which protrudes beyond the window in the distal member, and (3) a means for operating the cutting device. The tubular component comprises a distal end member containing a cutting device, a proximal member, and between the distal member and the proximal member a hollow, generally tubular intermediate member which deforms elastically when the angle between the distal member family proximal member is changed. The intermediate member can for example be composed of a nickel titanium alloy, and/or can be slotted, and/or can be in the form of an accordion, and/or be in the form of a coil.

Abstract: Eyeglass assemblies include an eyeglass lens having an engaging portion. The junction between the body portion of the lens and the engaging portion can consist essentially of smoothly curved surfaces. The engaging portion can be extend from the periphery of the lens or can be a recess in the lens. In some assemblies, under typical conditions of use, the engaging portion is maintained in contact with an eyeglass frame member by means of a removable bonding member (RBM). Under selected atypical ambient conditions, the RBM changes so that the engaging portion and the frame member can be separated. The RBM can be a suitable adhesive (RBA), or a component composed of a shape memory metal (RBSMA) or a material which softens when subjected to heat or other atypical condition.

Abstract: A pair of spectacles which comprises (1) a pair of lenses, each lens having an engaging portion on its periphery, and (2) an eyeglass frame which comprises two temple arms and a continuous bar connecting the two temple arms, the bar carrying two spaced-apart attachment portions which are fitted to respective engaging portions on the lenses.

Abstract: An eyeglass assembly which comprises (1) an eyeglass lens comprising a body portion and an engaging portion, and (2) a frame member which is fitted to the engaging portion, and (3) a securing member which is bonded to the engaging portion and to surfaces of the frame member which, in the absence of the securing member, are exposed to the atmosphere. In one method, the assembly is produced by applying a securing member, generally a laminar member, to exposed surfaces of the engaging portion and of the frame member fitted to the engaging portion, and securing the securing member to those exposed surfaces by an adhesive. In another method, the assembly is produced by heating and deforming part of the engaging portion of the lens so that it spreads out over adjacent surfaces of the frame member, thus forming a melt bonded securing member.
