Patent number: 7549976Abstract: A portal access device that is adapted to provide long term access to a port implanted in a patient has two major components, an infuser assembly and a safety needle insertion device. The infuser assembly has an infuser housing that can be configured into a specific shape, for example a dome. A blunt cannula is attached to and extends downwardly from the underside of the infuser housing. Also connected to the infuser housing, preferably at a side thereof, is a tubing or catheter. The safety needle inserter assembly has a base having a proximal portion that is configured to form fit over the infuser housing. At the distal portion of the base uprights are provided so that a second end of an arm, to which first end a needle or a sharp cannula is connected, may be movably and hingedly connected to the base. The sharp cannula extends from the underside of the proximal end of the arm and passes through the base by way of a bore formed at the proximal portion of the base.Type: GrantFiled: December 28, 2005Date of Patent: June 23, 2009Assignee: Smiths Medical MD, Inc.Inventors: Lester D. Michels, William L. Beling, Ronald G. Travis

Patent number: 6332877Abstract: A catheter or ostomy tube placement tip is comprised of a tapered, substantially conical head portion and a cylindrical body or stem portion centrally attached to the base thereof. The cylindrical base fits snugly within the lumen of a catheter or ostomy tube such as a ostomy or jejunal feeding tube and its tapered design allows for the insertion and placement of the tube within the lumen of the stomach or other body cavity through an opening or ostomy. Once properly placed, the tip is discharged from the end of the tube so that it is dissolved by human body fluids and is excreted.Type: GrantFiled: May 12, 1998Date of Patent: December 25, 2001Assignee: Novartis AGInventor: Lester D. Michels

Patent number: 6039714Abstract: The present invention is an improved ostomy fluid tube and method for its use comprising a collapsible retention bolster for securing the tube to the inner stomach wall and fascia. The retention means comprise several resilient leaf or petal-shaped flanges circumferentially arranged about the feeding tube at a distal point thereon. The otherwise flat, circumferentially arranged flanges possess notches or grooves which facilitate collapse or folding of the retention means for easier removal through an ostomy or other internal cavity.Type: GrantFiled: May 12, 1998Date of Patent: March 21, 2000Assignee: Novartis Nutrition AGInventors: Raymond F. Cracauer, Lester D. Michels

Patent number: 5902285Abstract: The present invention comprises an improved jejunal feeding tube comprising semi rigid tubing attached to the distal end of a percutaneous endoscopic feeding tube. The tubing further contains equidistantly spaced bushing grips on the jejunal feeding tube for ease of placement and securing the jejunal feeding tube to the small intestine.Type: GrantFiled: January 27, 1997Date of Patent: May 11, 1999Assignee: Novartis Nutrition AGInventors: Kenneth A. Kudsk, Lester D. Michels

Patent number: 5634907Abstract: An infusion apparatus includes a pump and a fluid delivery set. The infusion apparatus is adapted to monitor the fluid delivery set for insuring proper placement in relation to the pump. The infusion apparatus further includes a sensor which operates to detect the proper alignment of the fluid delivery set and also the proper operating position of the infusion apparatus. The infusion apparatus includes a cover which is adapted to be in a closed position when the infusion apparatus is in proper operating position. The cover operates to secure the fluid delivery set within the mounted position in the infusion apparatus.Type: GrantFiled: December 22, 1994Date of Patent: June 3, 1997Assignee: Sandoz Nutrition Ltd.Inventors: Robert G. Rani, Lester D. Michels

Patent number: 5628753Abstract: A gastrostomy feeding tube removal device is comprised of a hollow cylindrical body, a conical head formed at one end and preferably a cap or top at the other to assist in grasping the tool during use. A sheath covers the remaining body portion and is slideably moveable thereon. In use, the gastrostomy tube is pulled through the device which enters the stomach through an ostomy of the patient. Upon contacting the retention bolster means proximate the inner stomach lining, the plastic sheath is pressed forward against the extended members of the retention means thereby collapsing them and withdrawing them into the sheath. The device is then withdrawn from the patient's body simultaneously removing the tube as well.Type: GrantFiled: June 1, 1995Date of Patent: May 13, 1997Assignee: Sandoz Nutrition Ltd.Inventors: Raymond F. Cracauer, Lester D. Michels

Patent number: 5259367Abstract: Method for placing a guide wire through a gastrostomy tube which has a plug through which only the guide wire can pass in slidable communication. The plug prevents air from escaping from the stomach, thus, preventing the collapse of the stomach during the guide wire placement. The plug may comprise a substantially cylindrical member having a longitudinal bore for receiving the guide wire in slidable communication.Type: GrantFiled: October 25, 1991Date of Patent: November 9, 1993Assignee: Sandoz Ltd.Inventors: Donald F. Kirby, Lester D. Michels, Frederick K. Reuning
