Patent number: 9968350Abstract: A blunted safety needle is provided, which includes a hollow needle having a sharp distal tip and a stylus having a blunted end. The stylus is positioned within at least a portion of the needle. After the needle is used to deliver or deploy a substance and/or a device, the blunted end of the stylus is positioned to extend through the sharp distal tip of the needle and un-releaseably lock into position, thereby providing a blunted safety needle assembly.Type: GrantFiled: January 19, 2016Date of Patent: May 15, 2018Assignee: Avent, Inc.Inventors: John Anthony Rotella, Nathan Christopher Griffith, Lanita Grayce Cox, Donald Jay McMichael

Patent number: 8382772Abstract: A gastropexy kit includes a plurality of safety needle assemblies. Each safety needle assembly includes a needle and a stylus. A fastener is positioned in a distal end of the needle. The fastener is coupled to one end of the suture and a suture retention hub is coupled to an opposite end of the suture. The fastener is deployed in a patient's stomach via the needle and stylus which has a blunt distal end which extends through the needle to push the fastener out of the needle and to blunt the needle. The suture retention hub is positioned on a patient's skin and adjustably tensions the suture, which, desirably, is a resorbable suture.Type: GrantFiled: April 16, 2012Date of Patent: February 26, 2013Assignee: Kimberly-Clark Worldwide, Inc.Inventors: John Anthony Rotella, Donald Jay McMichael, Nathan Christopher Griffith, Thomas Gregory Estes

Publication number: 20120191040Abstract: The invention describes a closure device for the provision of freshly created gastric feeding fistulas, the basis of the design of the device being an introverted balloon that allows a sealing and hemostatic axial traction movement on the fistula that is to be sealed, the concentric balloon ends which run transmurally through the stomach and abdominal wall being arranged in a special seal-promoting and hemostatic manner.Type: ApplicationFiled: February 24, 2012Publication date: July 26, 2012Inventors: Fred Gobel, Donald Jay McMichael, Lanita Grayce Cox

Patent number: 8211136Abstract: A stoma dilator is provided which has a base dilator and a plurality of dilators which are coaxially disposed over the base dilator. The base dilator has a hub and an opening therethrough. The base dilator is configured to be positioned over a wire into a patient's tissue. Each of the plurality of dilators has a tapered distal end, a proximal end, and a tubular body, and are held in separated, telescoping position by the dilator positioner such that a portion of each distal end is exposed from beneath another dilator and is graspable by a health care practitioner for movement such that a smaller diameter dilator does not become inaccessible inside of a larger diameter dilator. The stoma dilator may include a hollow sheath positioned over an outermost dilator. The sheath is configured to hold open a tissue opening created by the plurality of dilators. The base dilator and the plurality of dilators may be removed while the sheath remains in a tissue opening.Type: GrantFiled: August 31, 2007Date of Patent: July 3, 2012Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Nathan Christopher Griffith, Donald Jay McMichael

Patent number: 7867253Abstract: A suture retention hub is provided. It includes a base configured to moveably hold a handle within at least a portion of the base. The base has an aperture which extends through the base. The hub also includes a handle configured to moveably fit into the portion of the base. The handle has an aperture formed therethough as well. When a suture is positioned in the apertures and the base and handle are positioned such that the apertures are substantially in an axial alignment, the suture moves readily through the apertures in the hub. Then the base and handle are positioned such that the apertures are not in a substantial axial alignment, the suture is frictionally crimped and it is prevented from moving through the hub.Type: GrantFiled: August 31, 2007Date of Patent: January 11, 2011Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Donald Jay McMichael, John Anthony Rotella, Nathan Christopher Griffith, Thomas Gregory Estes

Publication number: 20090326490Abstract: A fecal collection device has a base with a substantially closed proximal end and a substantially open distal end. The base includes a first balloon positioned about an outer surface of the proximal end and a second balloon positioned next to the first balloon. The device also has a catheter having a lumen which is in fluid communication with the base. The first and second balloons are inflated and deflated in a sequence so that pressure against the colon wall is alternated such that the device via the balloons does not cause continuous pressure to the same area of the colon wall. In some instances, fecal material accumulated between an outer surface of the proximal end and the colon wall is moved upward by at least one balloon such that it flows into the proximal end of the base and is eliminated via the catheter.Type: ApplicationFiled: June 30, 2008Publication date: December 31, 2009Inventors: Donald Jay McMichael, Sharon Pamperin, Valerie Lynn Cansler

Publication number: 20090254039Abstract: A removable cover for an intracorporeal medical device is provided. The removable cover is adapted to surround the tether so that the tether of the intracorporeal medical device is not exposed to the outside environment after insertion of the tether into the central opening of the medical device in order to desirably decrease the prevalence of bacteria within and about the central opening. The removable image may also, desirably, include images thereon which encourage the use of the intracorporeal medical device by patients.Type: ApplicationFiled: December 21, 2007Publication date: October 8, 2009Inventors: Nicole Sams O'Brien, Donald Jay McMichael, John Kenneth Bacon
