    Abstract: A novel suture anchor installation tool which comprises an elongated member having a first end and a second end and a slot extending from the first end towards the second end, the slot being sized to snugly accommodate the suture anchor's barb, whereby the suture anchor may be attached to the elongated member at the first end of the elongated member by fitting the barb into the slot so that the barb extends upward and outward from the first end of the elongated member, through the slot, with the body of the suture anchor engaging the first end of the installation tool.In use, the suture is first attached to the suture anchor and then the suture anchor is attached to the elongated member in the foregoing manner. Then the first end of the elongated member is pressed into a predrilled hole in the bone, forcing the suture anchor in ahead of it. As the suture anchor is pressed into the bone, its barb engages the side wall of the bone and is forced to retract backwards into the elongated member's slot so that it extends somewhat parallel to the elongated member. When the suture anchor bottoms out in the bone hole, and the elongated member is thereafter withdrawn, the barb's engagement with the bone wall will cause the suture anchor to separate from the elongated member, leaving the suture anchor (and its attached suture) anchored securely in the bone.

    Abstract: A surgical blade unit for receiving substantial cutting load and adapted for use with a selected shaft-form handle that has, at its distal end, an axially aligned blade-unit receiving opening. The blade-unit includes a metal blade defining a working edge and a load-transmitting, axially elongated metal support shank extending from the edge, and a intermediate load-transferring member of synthetic resin permanently molded about a proximal portion of the shank and defining an attachment fitting adapted to engage in load-transferring relationship with the handle. The proximal portion of the shank extends through the intermediate member in the attachment fitting region and is permanently embedded therein to define an elongated, load-transferring interface therewith. The intermediate member has substantial tensile and shear strength and is constructed and arranged to receive via the attachment fitting the surgeon's forces on the handle, and to receive via the substantial load-transferring interface, forces from the proximal end of the shank attributable to the resistance encountered by the metal blade, the substance of the intermediate member being adapted to transfer the surgeon's forces to overcome the resistance forces while maintaining the blade in fixed relationship to said handle. In preferred aspects of the invention, the attachment fitting comprises cooperatively acting threads on the handle and a proximal portion of the intermediate member, the blade unit is in the form of an arthroscopic retrograde blade, the unit being sized to lie within a surgical cannula and having a working edge disposed for reverse cutting.

    Abstract: A bone fastener including an expandable member having an axial channel and an elongated element insertable into the axial channel is described. The expandable member is configured to be insertible into a bore drilled in bone. The distal end of the expandable member also may include a structure for axially releasing the expandable member from an emplacement device that places the expandable member into a bone opening. In one embodiment, the structure for axially releasing includes a frangible membrane capable of being severed from the expandable member during emplacement of the expandable member in a bone opening. A rivet for coupling an object to bone for use with an expandable member is also described. The distal end of the elongated element is shaped into a radially projecting portion adapted for engagement with a washer that contacts the object to be coupled. The washer, having upper and lower surfaces and a bore defined between the surfaces, is disposed around a portion of the shaft. The elongated element is adapted for movement independent of the washer since the radial projection of the element has a different radius of curvature than the washer. An apparatus for use within an endoscope is described. The apparatus includes an elongated, substantially hollow holding means for emplacing a bone fastener of the invention in a bone opening. The expandable member includes a structure for axially releasing the expandable member from the holding means. A method of attaching soft tissue to bone is also described. The invention also includes a surgical fastener kit.

    Abstract: An incriment optical signal from a potential enemy threat is captured by an array of apertures which are connected to a number of broadband filters. The broadband filters have overlapping band pass regions to cover the wavelength spectrum of potential threats, but not with the spectral resolution of a larger number of narrowband filters. To further increase resolution without adding additional filters, each broadband filter is connected to an optical delay line which converts wavelength into a time delay. To enable measurement of the time delay, additional optical lines with no relative delay are connected directly from the apertures. The time difference between when a signal arrives over optical delay lines from the filters and when a signal arrives over optical lines directly from the array of apertures is then reconverted to wavelength to a high degree of resolution.
