Title: Apparatus and methods for aspirating emboli
Inventor: SALAHIEH AMR
IPC: A61B17/22
Filed: 2002-07-18
Abstract: Apparatus and methods for aspirating emboli from a vascular filter (30) or stent within a patient's circulatory system are provided. A filter sac (33) of the vascular filter permits blood flow and captures emboli from the flow. Th e aspiration device removes emboli from within or proximal to the vascular filter or stent to reduce the risk to the ischemia during retrieval of the vascular filter and during a treatment procedure. Two families of aspiration devices are provided: a single catheter type and telescoping dual catheter type. The single catheter type uses one catheter both to aspirate emboli and retrieve a vascular filter. The telescoping dual catheter type device uses t wo catheters, with one catheter disposed inside the other, so that the inner catheter is used to aspirate emboli from a vascular filter and the outer catheter being used to retrieve the vascular filter. Aspiration through the catheters may be accomplished using a syringe coupled to the catheter via a hemostatic valve.

Title: A dental floss device
Inventor: SULLIVAN PAUL
IPC: A61C15/04
Filed: 2002-11-22
Abstract: A dental floss device (1) comprises a handle (2) having a head piece (3) and a disposable holder (4) for a length of dental floss (5). The holder (4) comprises a base portion (20) and a pair of spaced-apart jaws (21) extending from the base and which extend to embrace the head piece (3) of the handle (2) when the holder (4) is in a correct alignment configuration with respect to the handle (2). The device has an interlock which ensures that the holder (4) can be interengaged with the head piece (3) only when the holder (4) is correctly aligned with the head piece (3). The interlock comprises a head interlock part provided by interlock grooves (10) and a holder interlock part provided by corresponding interlock tongues (11).  There are two interlock grooves (10) and corresponding interlock tongues (11) which slidably interengage when the holder (4) is correctly aligned with the head piece (3). If the holder (4) is turned so that it is not correctly aligned with the head piece (3), the interlock tongues (11) of the holder (4) prevent engagement of the holder (4) with the head piece (3).  Thus there is no risk that a user will incorrectly align and engage the dental floss holder with the head piece (3).

Abstract: A power disk alternator includes a rotor arranged to rotate about an axis, having a circular cross section, and having at least two disks facing each other and defining at least one gap therebetween. The rotor has a shaft connected to an external source for driving the shaft in rotation about the axis. A circular array of magnetized elements is located in equally arcuately spaced relation adjacent to the periphery of each disk, each of the magnetized elements having surfaces of opposite polarity and being disposed in side-by-side relationship in an alternating polarity configuration. Magnetized elements of one disk face magnetized elements of the other disk of opposite polarity to create between the twa disks in the air gap the magnetic fields of the opposite polarities. The alternator also includes a stator having at least one fixed disk made of a nonmetallic material having a conductor path on at least one surface thereof, each of the stators being located in one of the at least one air gap.

Abstract: The present invention provides a method and apparatus incorporating a spinning, oscillating or stepping optical interference filter (109) to change the angle at which light (102) passes through the filters after passing through a sample (105) under analysis downhole. As each filter is tilted, the color or wavelength of light passed by the filter changes. Black plates are placed between the filters to isolate each filter's photodiode. The spectrometer of the present invention is suitable for use with a wire line formation tester to provide supplemental analysis and monitoring of sample clean up. The present invention is also suitable for deployment in a monitoring while drilling environment. The present invention provides a high resolution spectometer which enables quantification of a crude oil's percentage of aromatics, olefins, and saturates to estimate a sample's gas oil ratio (GOR). Gases such as CO2 are also detectable. The percentage of oil-based mud filtrate contamination in a crude oil sample can be estimated with the present invention by using a suitable training set and chemometrics, a neural network, or other type of correlation method.
