Patent number: 7875020Abstract: The present invention provides an inventive apparatus and method for docking of a male luer connector fluidly interconnected or interconnectable to a medical liquid source during one or repeated periods. As such, the invention has particular application to multiple-dose medication therapy procedures. The docking apparatus comprises a holding receptacle having a single access opening and a depressible member disposed in the holding receptacle. The holding receptacle is adapted for retentive engagement with a male luer connector (e.g. via complementary threading), wherein upon docking a nozzle of the male luer connector is isolated within the holding receptacle. An anti-bacterial material may be readily applied to a top surface of the depressible member prior to docking so that the forward edge of the nozzle of the male luer connector contacts the anti-bacterial material when docked. The docking apparatus may be provided with lateral and rearward handling members to facilitate docking procedures.Type: GrantFiled: May 18, 2009Date of Patent: January 25, 2011Assignee: Baxa CorporationInventors: Gerry Tighe, Brian Eugene Baldwin, Joseph V.

Patent number: 7842006Abstract: The present invention is an ultrasonic thrombectomy catheter that produces physical forces (shear rates) strong enough to emulsify obstructions such as thrombi and emboli without causing damage to arterial walls. This is accomplished by properly arranging piezoelectric transducers within a catheter and a tubular catheter head separated by a gap to generate acoustic streaming that simultaneously emulsifies the obstruction and sweeps resulting debris into a catheter lumen for removal. The open gap may be formed by supporting struts that connect the catheter to the catheter head. The design of the catheter tip allows the fabrication of catheters capable of removing partial or complete blockages from arteries and other vessels having diameters as small as 2 mm.Type: GrantFiled: November 17, 2006Date of Patent: November 30, 2010Assignee: CFD Research CorporationInventors: Guiren Wang, Shivshankar Sundaram, Kapil Pant, Jianjun Feng, Peter Storm

Patent number: 7811253Abstract: An insufflation gas warmer and humidifier apparatus and methods are provided. Insufflation gas is received from a bulky insufflation tubing. Insufflation gas received travels through, in one aspect, a channel or winding flow path, in a passage. The configuration of the passage ensures that the insufflation gas, which travels through the passage, receives sufficient heat and moisture. A humidifying reservoir humidifies the insufflation gas as the insufflation gas is passed to the passage. In one aspect, an oxygenator introduces slight amounts of oxygen into the insufflation gas. A warmer connected to the passage warms the gas in the passage. The warmer, in one aspect, contains a reactive agent that when exposed to air produces heat that is transferred to the passage to warm the insulation gas within the passage.Type: GrantFiled: December 9, 2004Date of Patent: October 12, 2010Assignee: Applied Medical Resources CorporationInventors: Charles C. Hart, John R. Brustad, Zoran Falkenstein

Patent number: 7811258Abstract: A securement device includes a simply-structured retention mechanism that permits a portion of a catheter hub or a similar medical article to be easily anchored to a patient, without the use of tape or needles and suturing. A unitary retainer desirably includes a base defining a locator mechanism. The locator mechanism interacts with a fitting of the medical device so as to position the medical device relative to the retainer. The locator mechanism also desirably guides the medical device fitting into contact with an adhesive member mounted on an outer surface of the retainer. In one form, the locator mechanism includes one or more posts that engage mating holes defined in the medical device fitting. In other forms, the locator mechanism includes a cradle defining an arcuate channel to receive a convex surface of the medical device, or a recess shaped to matingly receive the fitting.Type: GrantFiled: March 3, 2006Date of Patent: October 12, 2010Assignee: Venetec International, Inc.Inventor: Steven F.

Patent number: 7806890Abstract: A medical device includes a vascular access device with an access port having a septum and a slit. The slit is formed on the inner surface of the body of the septum where the access port receives an access device that is separate from the vascular access device through the slit of the septum. A pivoting member in communication with the access port pivots when the port is accessed by an access device. The medical device may be used to control the volume displacement of a chamber within the medical device by decreasing the volume of the chamber by inserting a substance having a mass into the chamber, pivoting a structure associated with the chamber, and increasing the volume of the chamber simultaneously and commensurately with the mass of the substance inserted into the chamber.Type: GrantFiled: July 26, 2007Date of Patent: October 5, 2010Inventors: Austin Jason McKinnon, Weston F. Harding, Christopher N. Cindrich, Kelly D. Christensen, S. Ray Isaacson, Chad M. Adams, Frank Holloway

Patent number: 7803132Abstract: A syringe includes a hollow barrel, a hollow plunger movable within the barrel and a needle assembly secured within and at a distal end of the barrel. The needle assembly includes a needle holder, a resilient member that biases the needle holder toward the proximal end opening of the barrel, and a retaining member releasably secured to the needle holder via a reduced material section. The retaining member maintains the needle holder at the distal end of the barrel against the bias of the resilient member. When the plunger is fully depressed within the barrel, the plunger engages the needle holder such that the retaining member is forced to break away and separate from the needle holder along the reduced material section to facilitate retraction of the needle holder and a needle secured to the needle holder into the retraction cavity disposed within the plunger.Type: GrantFiled: October 14, 2005Date of Patent: September 28, 2010Inventors: Gregory A. Janek, Vincent Runfola, Li Xian Yu

Patent number: 7799001Abstract: A catheter securement device holds a medical article such as a catheter hub or a connector fitting in position upon the body of a patient and at least inhibits longitudinal movement of the medical article. The securement device includes a retainer and at least one anchor pad. The retainer forms a central channel into which at least a portion of the medical article is inserted. The retainer includes at least one abutment that can abut against a contact point or surface on the medical article. The abutment, in conjunction with a second abutment and/or a tapering shape of the central channel, inhibits motion of the medical article in proximal and distal directions through the central channel. For this purpose, the abutment surface(s) can lie either within or outside the channel.Type: GrantFiled: January 30, 2006Date of Patent: September 21, 2010Assignee: Venetec International, Inc.Inventor: Steven F.
