Patent CA-2292585-A1 (CA)
Inventor: KLOPOTEK PETER J
IPC: A61F9/007
Filed: 1998-06-01
Abstract: Methods and apparatus are diclosed for removal of biological tissue slices or layers, preferably in the form of lamellar sections (4) of predetermined shape and thickness employing a reference member (12) that engages a target tissue site and cooperates with a cutter (14) in order to remove the tissue segment or lamella. The cutter can include a flexible cutting element such as a wire or band element that is brought into physical contact with a guiding edge (8) integrated with, or otherwise coupled to, the reference member. Alternatively, the cutter can include a stiff rigid blade element (14B) that is maintained in contact with the guiding edge. The cutter is drawn along a path defined by the guide edge through the tissue to sever, at least partialy, a tissue section. In one particularly useful aspect of the invention, devices for keratectomy are diclosed employing an ocular reference member that engages the upper central region of the cornea and cooperates with a cutter to remove a lamellar segment from the cornea. Such lamellar resections are useful in preparing the cornea for further surgery (by mechanical or laser surgical techniques), or in performing refractive keratectomy directly upon the eye, or in treating (e.g., smoothing) the corneal surface to correct abnormalities, (e.g., to remove ulcerated tissue or otherwise improve the optical properties of the cornea).

Title: Method for forming silica by combustion of liquid reactants using oxygen
Inventor: HAWTOF DANIEL W
IPC: C01B33/18
Filed: 1998-07-07
Abstract: The present invention is directed to a method for making silica. A liquid siloxane-containing feedstock capable of being converted by thermal oxidative decomposition to SiO2 is provied and introduced directly into the flame of a combustion burner, which converts the compound to silica, thereby forming finely divided amorphous soot. The soot is vaporized at the conversion and/or deposition site where the liquid is converted into silica by atomizing the liquid with a stream of oxygen gas, or a mixture of oxygen gas and other gas, such as nitrogen. The amorphous soot is deposited on a receptor surface where, either substantially simultaneously with or subsequently to its deposition, the soot is consolidated into a body of fused silica glass, such as an optical fiber preform.

Patent CA-2306561-A1 (CA)
Title: Bubble detection
Inventor: CELLIERS PETER M
IPC: A61B18/20
Filed: 1998-09-29
Abstract: The present invention is intended as a means of diagnosing the presence of a gas bubble and incorporating the information into a feedback system for opto-acoustic thrombolysis. In opto-acoustic thrombolysis, pulsed laser radiation at ultrasonic frequencies is delivered intraluminally down an optical fiber and directed toward a thrombus or otherwise occluded vessel. Dissolution of the occlusion is therefore mediated through ultrasonic action of propagating pressure or shock waves. A  vapor bubble in the fluid surrounding the occlusion may form as a result of laser irradiation. This vapor bubble may be used to directly disrupt the occlusion or as a means of producing a pressure wave. It is desirable to detect the formation and follow the lifetime of the vapor bubble. Knowledge of the bubble formation and lifetime yields critical information as to the maximum size of the bubble, density of the absorbed radiation, and properties of the absorbing material. This information can then be used in a feedback system to alter the irradiation conditions.

Filed: 1992-09-09
Abstract: A tubeless inner tire or shield 14 provides for easy assembly of the shield 14 into the outer tire 12 and over the rim 16 as compared to previous designs.      The beads 43 in the shield comprise stranded filaments and the bead portion 40,42 of the shield 14 has increased flexibility. The increased flexibility of the bead portion 40,42 eliminates kinking of the shield 14 upon assembly which could prevent the shield 14 from properly sealing against the rim 16. Air passageways 44 between the inner shield 14 and outer tire 12 are provided on the shield 14 near the bead portion 42. The air passageway 44 includes a protrusion 50 extending from the surface of the shield and has an inclined radially inner surface 58. The inner surface 58 is at an angle of 25° to 60° relative to a plane perpendicular to the axis of rotation of the inner shield 14. The inclined inner surface 58 of the protrusion 50 facilitates the assembly of the inner tire 14 and the outer tire 12 on a rim 16.
