Patent number: 6517517Abstract: An automated injection device for administration of one or more liquid medicaments that is particularly useful for self-administration of liquid medicaments such as those used to treat anaphylactic shock, heart attack, exposure to toxic agents, or other conditions may include a number of features designed to reduce both the size and complexity of the device. With reduced size, the device may provide greater convenience and portability. Importantly, the reduced size may encourage more users to carry the device, and thereby reduce the risks associated with the conditions mentioned above. With reduced complexity, the device can be constructed at a lower cost. Moreover, the device can be more reliable and simple to operate.Type: GrantFiled: June 8, 2000Date of Patent: February 11, 2003Assignee: Mayo Foundation for Medical Education and ResearchInventors: Gianrico Farrugia, Mark H. Ereth, William W. Brooks, Jr., Jerry Neubauer, Jim Rigotti, Peter Schuller

Publication number: 20030009135Abstract: An epidural space locating device for locating an epidural space, the device comprising a body section having a first end and a second end and a longitudinal passageway extending therethrough, the first end of which is coupleable to a luer assembly; and a collapsible bellows chamber having one end coupled to the second end of the body section and the other end exposed so as to permit pressure to be exerted thereon by one or more digits of a hand, wherein positive pressure within the bellows chamber maintains the integrity of the shape of the bellows chamber and wherein negative or zero pressure within the bellows chamber facilitates the collapsing of the shape of the bellows chamber thus indicating the locating of the epidural space by a needle that is coupled to the luer assembly; wherein the loss of pressure within the bellows chamber is sensed by the one or more digits of the hand as the shape of the bellows chamber collapses.Type: ApplicationFiled: July 6, 2001Publication date: January 9, 2003Inventors: James F. Fitzgibbons, Christopher S. Young

Patent number: 6500156Abstract: A catheter flushing device includes a chamber covered with a movable member (e.g., a flexible diaphragm) that can be compressed by exertion of pressure on the diaphragm; and a valve having a first position allowing fluid from a fluid source to fill the chamber, and a second position allowing fluid from the chamber to flow through the catheter when pressure is exerted on the movable member. In particular, the catheter flushing device includes a housing having a cylindrical valve opening, an inlet port for connection with the fluid source, and an outlet port for connection with the catheter. The chamber is defined by a flexible diaphragm sealed about a region of the housing. The chamber can be compressed by manually exerting pressure on the diaphragm by means of a thumb or finger. A passageway extends through the housing from the chamber to the valve opening.Type: GrantFiled: October 3, 2000Date of Patent: December 31, 2002Assignee: McKinley Medical L.L.L.PInventor: L. Dean Stansbury

Patent number: 6497686Abstract: A method and related device for performing sterile medical procedures are disclosed. The method and related device are capable of accessing a sterile environment from a non-sterile environment to perform a medical procedure within the sterile environment. The method and related device can achieve a sterile technique during endoluminal procedures and in uncontrolled and unsterile environments. The device includes an inner hollow member moveably disposed within an outer hollow member. The outer hollow member is adapted to penetrate a boundary separating non-sterile and sterile environments and the inner hollow member is adapted to extend past the outer hollow member and into the sterile environment. A fluid compartment is adapted to be in selective fluid communication with the outer tube such that when the inner member extends past the outer member and into the sterile environment, fluid enters the outer member and the boundary.Type: GrantFiled: April 21, 2000Date of Patent: December 24, 2002Assignee: SCIMED Life Systems, Inc.Inventors: Ronald D. Adams, Roy H. Sullivan

Patent number: 6485471Abstract: A fluid-delivery apparatus for delivering a medicament to a patient is provided in accordance with the present invention. The apparatus includes a housing defining a passageway, a bellowed ampoule positioned to lie in the passageway of the housing, and a piston. The bellowed ampoule includes a body with first and second ends and is formed to define a cavity configured to contain the medicament. The piston presses the second end of the ampoule toward the first end to dispense the medicament from the cavity. In addition, the fluid-delivery apparatus includes a visible non-linear scale that represents the relationship between a volume of medicament delivered from the first end of the ampoule and a distance that the piston has traveled in the housing toward the first end.Type: GrantFiled: March 3, 2000Date of Patent: November 26, 2002Assignee: Roche Diagnostics CorporationInventors: Maury Zivitz, Raghbir Singh Bhullar, Brian S. Hill

Publication number: 20020091361Abstract: A multiple-dose syringe including a barrel with a closed end and an open end, the closed end having an injection port adapted to receive a needle. A plunger is slidably disposed through the open end of the barrel. A container is connected to an end of the plunger to move with the plunger. The container has a deformable shell with an opening at a forward end thereof and a predetermined quantity of fluid sealed therein by a closure member disposed over the opening. The container is slidably disposed in the barrel and includes a seal proximal to the forward end to form a first cavity in the barrel with a volume that is adjustable by moving the container in the barrel with the plunger so that fluid can be selectively drawn into and expelled from the first cavity. After at least a substantial portion of the fluid is expelled from the first cavity, the shell is configured to be collapsed by further pressure applied by the plunger to expel the predetermined quantity of fluid contained therein.Type: ApplicationFiled: March 7, 2002Publication date: July 11, 2002Inventors: Jack P. Rosoff, Michael N. Hirsch, Ali S. Salem
