Patent number: 6875163Abstract: An industrial sponge device and a method of manufacturing the same. The sponge is made from a polyvinyl acetal material with a process in which the pores are formed by gas to provide an open pore structure having no fibrils. Additionally, the sponge is purified by an extracting process which includes alternating exposure of the partially cross-linked sponge to solutions of high pH and low pH. The sponge is sterilized by electron beam radiation to destroy micro organisms that can cause contamination of the final product. The resulting sponge material is formed into an industrial sponge having a cylindrical body and a plurality of projections extending from the body. The projections are tapered truncated cones having a cross-sectional radius that decreases with distance from the body. The extracting process permits residual amounts of calcium, zinc, and other elements to be 2 ppm or less, preferably 1 ppm or less.Type: GrantFiled: February 13, 2003Date of Patent: April 5, 2005Assignee: Medtronic Xomed, Inc.Inventors: Ronald J. Cercone, Gerald D. Ingram, Leon C. Nunier, Scott J. Quaratella

Method for extracting residue from a sponge material and method of cleaning material with the sponge
Patent number: 6103018Abstract: An industrial sponge device and a method of manufacturing the same. The sponge is made from a polyvinyl acetal material with a process in which the pores are formed by gas to provide an open pore structure having no fibrils. Additionally, the sponge is purified by an extracting process which includes alternating exposure of the partially cross-linked sponge to acid and oxidizing solutions. The sponge is sterilized by electron beam radiation to destroy micro organisms that can cause contamination of the final product. The resulting sponge material is formed into an industrial sponge having a cylindrical body and a plurality of projections extending from the body. The projections are tapered truncated cones having a cross-sectional radius that decreases with distance from the body. The extracting process permits residual amounts of calcium, zinc, and other elements to be 2 ppm or less; preferably 1 ppm or less.Type: GrantFiled: June 11, 1998Date of Patent: August 15, 2000Assignee: Xomed Surgical Products, Inc.Inventors: Ronald J.

Patent number: 6004402Abstract: A method of cleaning a silicon material using a polyvinyl acetal sponge material. The sponge material is purified by an extracting process which includes alternating exposure of the sponge material to acid and oxidizing solutions. The extracting process permits residual amounts of calcium, zinc, sulfate, arsenic, barium, cadmium, chloride, chromium, copper, iron, lead, manganese, magnesium, mercury, nitrate, potassium, selenium, silica, silver and sodium to be 2 ppm or less. Following the extracting process, the silicon material is contacted with the sponge material to thereby clean the silicon material.Type: GrantFiled: March 9, 1999Date of Patent: December 21, 1999Assignee: Xomed Surgical Products, Inc.Inventors: Ronald J. Cercone, Gerald D. Ingram, Leon C. Nunier, Scott J. Quaratella
