Title: Method of assessing tissue viability using near-infrared spectroscopy
Inventor: STRANC MIROSLAW F
IPC: A61B5/026
Filed: 1998-04-02
Abstract: Prolonged and severe tissue hypoxia results in tissue necrosis in pedicled flaps. We demonstrate the potential of near-infrared spectroscopy for predicting viability of compromised tissue portions. This approach clearly identifies tissue regions with low oxygen supply, and also the severity of this challenge, in a rapid and non-invasive manner, with a high degree of reproducibility. Tissues remaining below a certain hemoglobin oxygen saturation threshold (oxygen saturation index < 1) for prolonged periods (> 6h) became increasingly dehydrated, eventually becoming visibly necrotic. Tissues above this threshold (oxygen saturation index > 1), despite being significantly hypoxic relative to the pre-elevation saturation values, remained viable over the 72 h post-elevation monitoring period. The magnitude of the drop in tissue oxygen saturation, as observed immediately following surgery, correlated with the final clinical outcome of the flap tissue.  These results indicate the potential of near infrared spectroscopy and imaging to monitor tissue oxygenation status and assess tissue viability following reconstructive surgery. Early, nonsubjective detection of poor tissue oxygenation following surgery increases the likelihood that intervention aimed at saving the tissue will be successful.

Title: Coil springs for cable support
Inventor: COLLIE CHARLES C
IPC: F16L7/00
Filed: 1999-04-07
Abstract: Helically wound coil springs (22) are wrapped around and attached at regular intervals to a cable (12), which is positioned within tubing (10). The support springs are attached to the cable to provide support to the cable. The upper section of each support spring is affixed to the cable. A remainder of each spring is formed in a long open helix facing downward when the tubing is installed in a well. The open helix portion of the spring is larger than the inside diameter (28) of the coiled tubing. During placement into the coiled tubing, the springs elongate and decrease in diameter. When the coiled tubing is installed vertically within a well, the springs compress due to the weight of the cable and engage the inside surface of the coiled tubing with a substantial portion of their length, thereby supporting the cable.

Patent CA-2332875-A1 (CA)
Inventor: MCCONNELL REBECCA
IPC: G01V11/00
Filed: 1999-05-28
Abstract: The invention is an acoustic transmitter (301, 401) that imparts vibratory stresses onto a signal propagation medium such as oil well tubing when actuated by an electric driver. In one embodiment, the acoustic transmitter (301, 401) utilizes a mechanical driver that includes piezoelectric elements (304) to generate the vibratory stresses. The acoustic transmitter (301, 401) is mechanically attached at only one point to the signal propagation medium. This single point attachment eliminates loading on the acoustic transmitter (301, 401) from compressive and tensile forces carried by the signal propagation medium. A  mass (406) backing the mechanical driver may be used to extend the frequency range over which the acoustic transmitter (301, 401) is operable. In addition, the resonance response of the acoustic transmitter (301, 401) may be minimized by the use of a viscous dampener (409). The viscous dampener (409) is configured to "couple" with the mechanical driver when the acoustic transmitter is operating and to "uncouple" with the mechanical driver at other times.

Patent CA-2335087-A1 (CA)
Inventor: LLOYD CHRISTOPHER JAMES
IPC: G01N21/64
Filed: 1999-06-24
Abstract: A method and apparatus for assessing the characteristic response of a medium to an excitation transient of predetermined duration which causes the medium to emit a series of signals over a period of time which is long relative to the duration of the excitation transient. The signals are detected and the duration of each interval between successive signals is measured. A  relationship relating the interval between the excitation transient and the emission of each signal to the interval between each signal and the preceding signal in the series is derived to represent the characteristic response. The interval between the excitation transient and the emission of each signal may be plotted against the interval between each signal and the preceding signal in the series and a curve may be fitted to that plot. The position of a minimum value of the interval between the excitation transient and the emission of each signal as represented by the curve is then determined, and the interval between successive signals corresponding to the position of the minimum is then determined to provide a measure of the characteristic response of the medium. The excitation transient may be a pulse.

Abstract: A variable focus intraocular lens (56) is provided that is a compound lens formed of two or more lenses (58, 60) attached together, and enclosing one or more closed central spaces or compartments (64) therebetween. When the lens is implanted inside the eye, the central space(s) contain sterile air, gas, and/or are at a reduced pressure (vacuum). If the power of the variable focus intraocular lens is to be changed, one or more of the central space(s) is opened (67) so that the aqueous humor enters the targeted lens compartment, and changes the power of the intraocular lens. The compartment can be opened either with a laser or surgically, e.g., through a weakened thin place in the wall of the central compartment, by removing a plug, by opening a valve, or the like.
