Method For Curing Polymeric Materials, Such As Those Used In Dentistry, And For Tailoring The Post-Cure Properties Of Polymeric Materials Through The Use Of Light Source Power Modulation

US Patent:

6384099, May 7, 2002

Filed:

Dec 8, 1999

Appl. No.:

09/457222

Inventors:

Calvin D. Ostler - Riverton UT
Kevin D. Ostler - Riverton UT
David W. Kaufman - Salt Lake City UT

Assignee:

Laser Med. Inc. - West Jordan UT

International Classification:

C08F 246

US Classification:

522 4, 522 2, 522908, 433 29, 427493, 427492, 523115, 523116

Abstract:

A method and system are disclosed for curing polymeric materials including dental composites. Preferably, modulated light is used to control the formation of polymer chains in the polymeric material so that a cured polymeric material that has the desired physical characteristics for its intended function is formed. Formation of short chain and long chain polymers from monomers in the polymeric material is initiated and controlled by using a light source with a wavelength suitable for one or more initiators found in the polymeric material.

Apparatus For Ventilating And Aspirating

US Patent:

5368017, Nov 29, 1994

Filed:

Mar 9, 1992

Appl. No.:

7/848030

Inventors:

James L. Sorenson - Salt Lake City UT
Valdon G. Reynolds - Bountiful UT
Stephen C. Mackert - Sandy UT
Joseph H. Jeffs - Sandy UT
David W. Kaufman - Salt Lake City UT

Assignee:

Sorenson Laboratories, Inc. - Salt Lake City UT

International Classification:

A61M 1600

US Classification:

12820026

Abstract:

A ventilating and aspirating apparatus for delivering respiratory gases to the trachea and the congested lungs and breathing passageways of a patient includes a flexible catheter tube extendable into and withdrawable from the patient's trachea. The catheter is housed within a pliable sheath extending from a manifold that is attachable to an endotracheal tube. The sheath has a slit defined by backing members formed along elongate opposed edges. A releasable, air tight "ziplock" seal is effected at the slit by a bead on one backing member and a groove to sealingly receive the bead on the other backing member. A "ziplock" actuator is structured as a slider member which travels along the bead and groove, and includes converging ends to hold the bead in the groove and a conduit member extending centrally through the slider member to interconnect an end of the catheter tube inside the sheath through a vacuum valve carried by the slider member outside the sheath to a vacuum source. The vacuum valve is operable by the same hand of a user that may be used to move the slider member.

Apparatus And System For Coordinating A Surgical Plume Evacuator And Power Generator

US Patent:

5342349, Aug 30, 1994

Filed:

Aug 18, 1993

Appl. No.:

8/108396

Inventors:

David W. Kaufman - Salt Lake City UT

Assignee:

Sorenson Laboratories, Inc. - Salt Lake City UT

International Classification:

A61M 100, A61B 1736

US Classification:

606 1

Abstract:

A surgical smoke filter and evacuator and a surgical power generator of the type used for electrocautery, laser surgery or the like are combined with an enclosure between the generator and the evacuator. The enclosure directs air which has been filtered of surgical plume contaminants from the evacuator past heat sink elements associated with the generator to facilitate dissipation of heat accumulated incidental to operation of the generator.
