The cap has a post for causing movement of the cartridge stopper toward the seal when the cap engages the medicament cartridge to thereby eliminate adhesion between the medicament chamber and the stopper. The medical injector according to the present invention includes the medicament loading system, i.e. a cartridge assembly, a needle free syringe assembly, and a power pack assembly.Type: GrantFiled: October 20, 2000Date of Patent: January 6, 2004Assignee: Antares Pharma, Inc.Inventors: Mark W. Rice, Paul R. Lesch, Jr., Sheldon J. Nelson, Timothy D. Byland

Patent number: 6673036Abstract: A portable, electric breast pump has an electronic controller adapted to track time and operate a solenoid to automatically maintain a predetermined suction and release rhythm as a function of time to mimic the natural sucking rhythm of an infant. Suction is produced by a continuously running diaphragm pump. A needle valve permits user vacuum level adjustment, but no other user control is required. A flapper valve in the top of the bottle reduces the suction rise time but incorporates a fixed amount of leakage to build a small amount of bottle pressure for pulling collected milk into the bottle during the release portion of the cycle. An improved bulkhead design helps to keep milk from entering the diaphragm pump if the unit is shaken or turned on its side.Type: GrantFiled: October 13, 2000Date of Patent: January 6, 2004Assignee: The First Years Inc.Inventor: James Joseph Britto

Patent number: 6673037Abstract: An improved breastshield for breastpumps has a tubular extension with a non-circular internal contour such as an oval, polygonal or fluted shape, among others. In another aspect of the invention, the non-circular contour is provided in the main breast-receiving part of the breastshield. Surface features, such as protuberances, are further provided for the breastshield which yield a non-smooth tactile feel to the breastshield.Type: GrantFiled: November 27, 2000Date of Patent: January 6, 2004Assignee: Medela Holding AGInventor: Brian H. Silver

Patent number: 6673039Abstract: Compositions, methods, kits, and apparatus are provided for delivering a macromolecular assembly such as a plasmid, virus vector, or other gene vector, to an extravascular tissue such as muscle tissue. The composition comprises the macromolecular assembly and a vascular permeability-enhancing agent. In another embodiment, the composition further comprises a vasodilating agent. The method of the invention comprises proving a vascular permeability-enhancing agent to a blood vessel and providing a macromolecular assembly to the vessel. An oxygenator useful for providing oxygen to a fluid extracorporeally prior to providing the fluid to a blood vessel of a mammal is included in the invention. Kits, apparatus, and methods for using the catheters described herein for isolating cardiac circulation, diverting caval blood flow from the right atrium, and for other purposes, are also described.Type: GrantFiled: June 19, 2000Date of Patent: January 6, 2004Assignee: Trustees of the University of PennsylvaniaInventors: Charles R. Bridges, Hansell H. Stedman

Patent number: 6673040Abstract: A system and methods are described for performing catheter based procedures on high risk patients that mitigate the risk to the patient and extend the acceptable time window for response when emergencies or complications arise. The system is useful for stopped heart catheter procedures or as a safety backup in beating heart catheter procedures and is compatible with concurrent or sequential surgical interventions. The system combines a therapeutic or diagnostic catheter subsystem with a selective aortic perfusion and cardiopulmonary bypass subsystem. The catheter subsystem may include catheters for angioplasty, stent delivery, atherectomy, valvuloplasty or other diagnostic or therapeutic procedures.Type: GrantFiled: August 27, 1999Date of Patent: January 6, 2004Assignee: Cardeon CorporationInventors: Wilfred J. Samson, John A. Macoviak

Patent number: 6673041Abstract: Described is a closed chest intravascular catheter system for a simultaneous biventricular approach to (1) intravascular cardiopulmonary surgery; (2) acute or prolonged mechanical circulatory support. The catheter system includes a left heart catheter and a right heart catheter with flow control members that segment the circulatory system into subcirculations of cardiopulmonary support. The left heart catheter has an elongated shaft with a first flow control member positioned at the entry site into a peripheral artery, a second flow control member positioned in the proximal descending aorta, a third flow control member positioned in the ascending aorta, and a fourth flow control member positioned within the left ventricle.Type: GrantFiled: August 29, 2000Date of Patent: January 6, 2004Assignee: Cardeon CorporationInventor: John A. Macoviak

Patent number: 6673042Abstract: The cannula of the present invention is useful for standard gravity drainage or vacuum assisted/suction drainage. The cannula of the present invention has a flexible shaft composed of a tubular body and an expandable scaffolding. The expandable scaffolding has a contracted position, facilitating insertion into a vessel and an expanded condition configured to allow optimal drainage in a vessel. The cannula is inserted into a vessel and navigated into an operative position within the patient's venous system. Once the cannula is in the proper position, the scaffolding is expanded either through passive, active, mechanic, hydraulic, pneumatic, thermal or electrical actuation. The cannula of the present invention is capable of expanding a collapsed vein to its normal diameter and/or capable of supporting the vein when suction is applied to the cannula to help increase fluid flow through the cannula.Type: GrantFiled: November 22, 1999Date of Patent: January 6, 2004Inventors: Wilfred J. Samson, Brady Esch, Michael J. Lee, Janine Robinson
