摘要： A fastener system for use in reattaching a skull flap in an opening formed in a patient's skull during brain surgery, is simple, quick, and easy to use, and is cost effective. The system includes a fastener element and a substantially disc shaped lock element. Both are made of bio-compatible radiolucent rigid plastic material. The fastener element has a substantially disc shaped head and a shank, the shank having substantially flat first and second substantially parallel surfaces having ratchet teeth on them. The shank typically has a thickness, with ratchet teeth, where it extends through a gap between the skull flap and the skull, of about 1-2 mm. The lock element has a through extending opening defined at least in part by locking teeth which cooperate with the ratchet teeth to allow the lock element to be brought tightly into contact with the skull and skull flap to hold the fastener and lock elements in place and to position the skull flap in the skull. The system, once installed, cannot be removed without actually cutting away the components.

摘要： Interlocking surface elements are created in such a way that there is almost 100% engagement between the surfaces, so that they positively lock together, and will not cam with respect to each other. Each element comprises a number of uniformly dimensioned semi-conically shaped surfaces emanating from a common center and disposed in an alternating inverted configuration. Each surface has first and second edges extending in a longitudinal direction. A flat surface of substantially constant dimension in a plane substantially perpendicular to the longitudinal direction connects the first and second edges of adjacent, alternately inverted, semi-conically shaped surfaces, so as to maximize the engagement area between the elements. The elements may be of vacuum formed plastic, molded plastic, or metal stampings. They may be circular (e.g. disc shaped) in plan, and the semi-conically shaped surfaces may all be hollow.

摘要： Cervical traction tongs having cooperating first and second curved arms made of MRI and biologically compatible and CT transparent material. Skull pins having main bodies of MRI and biologically compatible and CT transparent material, and pointed skull engaging tips of radiolucent material (e.g. single crystal alumina ceramic) extend through openings at one end of the arms, while at the other ends the arms are connected together in an adjustable manner, so as to adjust the spacing between the pin pointed tips. The arms have enlarged circular end terminations having radially extending serrations which cooperate together, and are held in a position to which they are moved by a through extending bolt and nut. The arms have sufficient elasticity to provide constant pressure urging the pointed pin tips against the human skull during use. A flexible strand for applying tension is passed through an arcuate elongated opening in the serrated end terminations of the arms. Torque limiting caps associated with the pins apply torque. When used to treat a human with an injury to the cervical spine, the tongs and skull pins are removed from sterile packaging, and once the human need no longer remain in traction, the tongs are disposed of.

摘要： A steerable medical probe device, such as a catheter, comprises a flexible, inner tubular body, a plurality of electrical conductors wrapped about the inner tubular body; and an insulating layer surrounding the conductors. Rigid non-conductive rings are adhesively secured at axially spaced locations along the distal end of the probe. A plurality of shape memory titanium-nickel wires extend between adjacent pairs of rings, and are electrically connected to a control device and power source. The control device may be operated to apply low current pulses selectively through one or more of the wires to effect contraction of the heated wires and thereby cause the distal end of the probe to bend in a desired direction.
