Title: Dispensing cabinet
Inventor: COBURN DONALD G
IPC: A61B19/02
Filed: 1998-03-03
Abstract: A dispensing cabinet has a rear panel, left and right transverse side panels that define a front access opening for the cabinet and a bottom access opening for the cabinet. At least one door is provided to selectively close the front access opening but the bottom access opening remains open. A longitudinally extending rail is mounted on the rear panel and, in a preferred embodiment, extends horizontally to slidably support at least one dispenser in an operative position which is adjacent to the bottom access opening. The dispenser has a bottom opening for dispensing selected articles and these are accessible for use through the bottom access opening. Normally, the door covering the front access opening will be shut and the dispensers are hidden from view. The support means for the dispensers on the rail are removable from the rail so that selected dispensers may be used according to the nature of the dispensed articles which are required.

Title: Controller for thermal treatment of tissue
Inventor: MAURER CHRISTOPHER W
IPC: A61B18/14
Filed: 1998-03-23
Abstract: Disclosed is an apparatus for use in conjunction with an RF ablation electrode insertable into a patient to ablate body tissue, e.g., prostate tissue of a patient with a BPH condition. The apparatus includes an RF generator for outputting RF current through the ablation electrode and a second electrode in contact with the patient to thereby ablate body tissue in the vicinity of the ablation electrode. Temperature measuring circuitry within the apparatus is coupled to a temperature sensor in a specific body region. An input means such as a plurality of switches on the apparatus housing is provided to enable a user to input a treatment volume corresponding to a target volume of body tissue to be ablated. Delivery of RF power is automatically terminated when a treatment time corresponding to the selected treatment volume is reached. In addition, a hypertonic saline syringe is preferably housed within the controller. Saline solution is caused to flow from the syringe into the treatment region at a controlled rate both immediately prior to and during the delivery of RF power.

Patent CA-2238968-A1 (CA)
Inventor: BROWN KYLE
IPC: A61F2/16
Filed: 1997-11-18
Abstract: A single piece intraocular lens folder that has a generally planar, open frame in the shape of a rounded "A" with a rimmed, open head at the top of the "A".  The base of the "A" forms a pair of opposing legs or handles that join to form a hinge at the intersection where the handles attach to the head. The hinge allows the handle to be squeezed together and spring apart when released.  Squeezing the handles together causes the sides of the head to spread apart, thereby stretching the top edge of the head rim and pulling the top edge downward toward the hinge. The open head contains a pair of support jaws and a pair of serpentine folding jaws. The location of the serpentine jaws is such that when the top edge of the head rim moves toward the hinge, the serpentine jaws are squeezed together, causing the IOL to be folded in half. The serpentine shape of the folding jaws allow the haptics to pivot downward, thereby permitting the IOL to be folded along a plurality of axes.

Patent CA-2248885-A1 (CA)
Title: Rod seal cartridge for progressing cavity artificial lift pumps
Inventor: DIETLE LANNIE L
IPC: E21B33/08
Filed: 1997-01-28
Abstract: A seal cartridge (11) particularly suitable for artificial lift pump rod sealing and for other applications where a rotating drive shaft penetrates a pressurized reservoir which is filled with abrasive laden liquids, mixtures or slurries. The cartridge (11) exploits a pressure responsive area of a wear sleeve (19) to eliminate internal bearing (13) running clearance in order to achieve a true-running rubbing surface which is conducive to the longevity of the compression-type rotary seals (21, 23, 27) which are employed. A cartridge mounting mechanism (9) is incorporated which overcomes stuffing box to rod (7) misalignment, and is readily adaptable to pumps made by different manufacturers. The cartridge (11) provides for leakage annunciation in the event of failure of a redundant rotary seal (21, 23, 27), and also provides for automatic pump shut down if a primary rotary seal fails. A redundant sealing arrangement between the wear sleeve (19) and rod (7) is incorporated which is relatively immune to installation damage, and to damage resulting from rod run out and vibration. By incorporation of a split drive clamp (39), the cartridge (11) is able to exploit space within the pump yoke which is ordinarily reserved for the occasional use of rod clamps. The cartridge (11) also incorporates an active cooling system (71) which dissipates heat generated by the seals and bearings.

Title: Tonometer air pulse generator
Inventor: LUCE DAVID A
IPC: A61B3/16
Filed: 1997-06-02
Abstract: An air pulse generator (110) for a non-contact tonometer comprises a bi-directional linear motor (124) drivably connected to a compression mechanism (114) and responsive to an applanation signal for reducing unnecessary air pulse energy delivered to an eye (2). Upon receiving the applanation signal from an applanation detector (140), a motor controller (138) reverses current flow in the coil (130) of the motor (124) to create a reverse electromagnetic force to stop generation of the air pulse. In a first embodiment, the linear motor (124) includes a moving permanent magnet armature (126) for reversibly driving the compression mechanism (114), while in a second embodiment, the linear motor (124) includes a moving coil (230) for reversibly driving the compression mechanism (214).

Abstract: A cutter element (62) having a substantially flat wear face and leading (64) and trailing (66) sections, wherein the leading section (64) is sharper than the trailing section (66). Sharpness is defined as either a smaller inside angle at the intersection of a pair of planes or as a smaller radius of curvature. The insert of the present invention experiences reduced stress on its trailing portion and therefore is less subject to extreme wear and failure.    The present invention can be applied with particular advantage to heel row cutters, but can also be~ applied to cutters in other rows that primarily ream the borehole wall.      The present cutter element can be constructed so as to have either a~ positive or negative rake angle at its~ leading section, or to have any of a variety of shapes, depending on the characteristics of the formation~ in which it is to be used.
