US Patent:
6705986, Mar 16, 2004
Filed:
Mar 18, 2003
Appl. No.:
10/391148

Assignee:
Embro Corporation - St. Louis Park MN
International Classification:
A61F 204
US Classification:
600 36, 128898, 623916, 623917
Abstract:
A system and a method for harvesting a section of a blood vessel from a patients body for further use. The system includes an expandable hood that creates a workspace for the dissection and removal of the vessel and a telescoping device that has tools at its distal end. The blood vessel is cut at a distal location and a light catheter inserted to illuminate the area of dissection. The system can remove a section of the saphenous vein for use in coronary bypass surgery.
Use Of Moss To Reduce Disinfection By-Products In Water Treated With Disinfectants
US Patent:
2013014, Jun 6, 2013

Sep 6, 2012
Appl. No.:
13/605377
Inventors:
David R. Knighton - Minneapolis MN, US

Assignee:
EMBRO CORPORATION - St. Louis Park MN
International Classification:
C02F 1/28
US Classification:
210662, 210691
Abstract:
A method of reducing disinfection by-products in water treated with disinfectants including contacting the water with an amount of a non-decomposed moss effective to reduce the level of disinfection by-products. A method of determining the effectiveness of a first method of reducing disinfection by-products in water treated with disinfectants, the first method including contacting the water with an amount of a non-decomposed moss effective to reduce the level of disinfection by-products, the method including determining the effectiveness of the first method by measuring the level of the disinfection by-products in water treated with disinfectants and contacted with the amount of non-decomposed moss.
Endoscope And Method For Vein Removal
US Patent:
5373840, Dec 20, 1994
Filed:
Oct 2, 1992
Appl. No.:
7/956904
Inventors:
David R. Knighton - Minneapolis MN
International Classification:
A61B 100
US Classification:
128 4
Abstract:
An endoscope for use in harvesting blood vessels includes a scope body of the type having a lumen extending longitudinally therethrough which itself has a proximal and a distal end. The endoscope includes means for viewing an area adjacent the distal end of the lumen, and the lumen has a lateral dimension of a size sufficient to accommodate the blood vessel being harvested and at least one tool for use in harvesting the blood vessel. A first end of the blood vessel section to be harvested is exposed through an incision in the patient's body. A dissecting tool and a gripping tool are inserted through the lumen of the endoscope and used to dissect the blood vessel away from the surrounding connective tissue of the patient's body, using the viewing means of the endoscope to view this dissection in process within the patient's body. Additional tools are provided for use through the lumen of the endoscope to remove body fluids and coagulate bleeding tissue, and to sever side branches from the blood vessel to be harvested, as well as to sever a distal end of the blood vessel to be harvested when a desired length of blood vessel has been dissected. Only a single small incision in the patient's body is necessary to harvest a relatively long length of blood vessel in a precise and controlled manner through endoscopic vision using the inventive endoscope and its related tools.
