Patent number: 8529532Abstract: Described generally herein are tissue therapy devices, which may comprise a sealant layer and a suction apparatus. The sealant layer functions so as to create a sealed enclosure between it and the surface of a patient by forming, preferably, an airtight seal around an area of tissue that requires negative pressure therapy. The tissue therapy device may comprise a suction apparatus. The suction apparatus is typically in fluid communication with the sealant layer and functions so as to reduce the amount of pressure present underneath the sealant layer. The reduced pressure is self-created by the suction apparatus. Together the sealant layer and the suction apparatus preferably create a closed reduced pressure therapy system. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of the air molecules under the sealant layer.Type: GrantFiled: September 26, 2011Date of Patent: September 10, 2013Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Moshe Pinto, Dean Hu, Kenton Fong

Publication number: 20130197449Abstract: A metered dose syringe includes a barrel having an open end and a opposing spaced apart port adapted to receive a needle. A plunger rod is provided and slidably disposed within the barrel through the barrel open end. Structure interconnected with the barrel and the plunger rod is provided for enabling stepwise movement of the plunger rod within the barrel. A syringe within the scope of our present invention permits injection of repeated and accurate doses due to the physical stops or dosage administered indicators.Type: ApplicationFiled: March 14, 2013Publication date: August 1, 2013Applicant: ALLERGAN, INC.Inventor: Allergan, Inc.

Patent number: 8486007Abstract: A pen injection device designed for use with dual or multi-chamber cartridges 14, is provided with an extended length plunger 24 having a non-drive portion 24? on its forward end and the usual screw-threaded drive portion 24? on its rearward end. This arrangement allows the plunger to be pushed forwardly while the dosing drive mechanism is disengaged to effect a reconstitution movement of the rearward bung 18? in the cartridge. Thereafter the threaded portion on the plunger 24? engages the drive mechanism to allow metered dosing.Type: GrantFiled: March 29, 2012Date of Patent: July 16, 2013Assignee: Owen Mumford LimitedInventors: Jeremy Marshall, Steven Mark Guy Rolfe

Patent number: 8444606Abstract: The invention concerns an injection device for apportioning set doses of a drug from a reservoir to a subject. The injection device comprises a housing having an interior thread formed as an outwardly pointing thread carried on an upstanding tower centrally located in the pen shaped device. This outwardly pointing thread forms a first thread connection with the interior thread of the rotatable scale drum. The injection device further comprises a driver for moving the piston rod forward when moved axially. The driver operates the piston rod through a second thread connection having a pitch different than the first thread connection.Type: GrantFiled: November 13, 2009Date of Patent: May 21, 2013Assignee: Novo Nordisk A/SInventors: Bo Radmer, Claus Schmidt Moller, Lars Morch Groth, Klaus Thogersen

Patent number: 8439930Abstract: A delivery device for semi-solid implantable material such as synthetic bone graft substitutes. The device comprises a handle (1), a cylinder (2) extending from the handle and having an outlet at its distal end. A piston (23) is operated by a trigger (5) and is slidable within the cylinder to displace the material from the cylinder. The cylinder has a substantially constant inner diameter along its entire length such that the outlet has substantially the same inner diameter as the rest of the cylinder. When the trigger is fully depressed, a ratchet mechanism (14, 32) is disengaged allowing the piston to be pulled back to a starting position.Type: GrantFiled: February 26, 2009Date of Patent: May 14, 2013Assignee: Apatech Ltd.Inventors: Charles Campion, Thomas Buckland, Paul Kearsley

Patent number: 8377004Abstract: A drug delivery pump drive which uses a linear piezoelectric motor to advance a syringe piston to deliver a liquid drug and a method thereof are disclosed. The pump drive, provided in a drug delivery pump, provides silent operation and very low energy consumption compared to electric motor-based drives. The small size of the motor helps also to reduce overall size of the pump drive and the resulting drug deliver pump.Type: GrantFiled: February 28, 2011Date of Patent: February 19, 2013Assignee: Roche Diagnostics Operations, Inc.Inventors: Christopher Wiegel, Marco De Polo, Steven Roe

Patent number: 8343101Abstract: Some injectors of the invention may include a fluid drive responsive to pressure of a working fluid (e.g., liquid, pneumatic, or both) to impart a sequence of forces to drive a delivery device (e.g., a syringe) to deliver a medical fluid (e.g., a contrast agent, a radiopharmaceutical, a drug, or a combination thereof). Some injectors may include a multimedia tube configured to pass a working fluid (e.g., air) and a light signal (e.g., infrared). Some injectors may include a peristaltic drive responsive to pressure of a working fluid.Type: GrantFiled: July 6, 2010Date of Patent: January 1, 2013Assignee: Mallinckrodt LLCInventors: Gary S. Wagner, Frank M. Fago, Peter Staats, Dane Battiato

Patent number: 8333739Abstract: A medication dispensing device with a housing and a member wherein the member is moveable in a distal direction is useful in delivering medication to a patient. A fluid container can be used with the device and often has a moveable piston at one end and an outlet at the other. The member receives a force from a user and drives the piston in the distal direction to expel medication. A intermediate system is disposed between the member and the piston including a gear set that has a pinion in meshed engagement with a rack. The system allows the member to move a greater distance than the piston moves thereby increasing the force on the piston.Type: GrantFiled: October 31, 2007Date of Patent: December 18, 2012Assignee: Novo Nordisk A/SInventor: Claus Schmidt Møller
