Patent number: 7905898Abstract: Lancet device that includes a body. A front cover includes a skin engaging end that includes a lancet opening through which a lancet needle extends. A holding member is movably mounted within the body. The holding member includes a front end and a rear end. The front end is configured to receive a lancet. A main spring is disposed between the front and rear ends of the holding member. A first stop surface is arranged on a front portion of the holding member. A second stop surface is axially retained to a front portion of the body. At least partial rotation of the front cover causes the skin engaging end to move axially relative to the second stop surface.Type: GrantFiled: August 15, 2003Date of Patent: March 15, 2011Assignee: Stat Medical Devices, Inc.Inventor: Steven Schraga

Patent number: 7901363Abstract: A device for sampling body fluid includes a housing having a sleeve at a forward end thereof which is displaceable in response to being pressed against a user's skin to trigger the firing of a lancet. After the lancet is removed from the incision, the sleeve is repeatedly pressed against the skin to depress a ring of body tissue in surrounding relationship to the incision to express body fluid outwardly through the incision. A pusher member is then actuated to push a capillary tube through a front end of the housing for drawing-in body fluid. The lancet is a disposable lancet which includes a body supporting a skin-lancing member and the capillary tube. The disposable lancet passes through an upper end of a lancet carrier when being installed or removed. The device cannot be armed until the disposable lancet is installed in the housing, because the capillary tube functions to push a safety device to a non-safety position.Type: GrantFiled: January 8, 2004Date of Patent: March 8, 2011Assignee: Roche Diagnostics Operations, Inc.Inventors: Brent G. Duchon, Joel S. Douglas, Jeffrey N. Roe, Ryszard Radwanski, Andrew M. Drexler

Patent number: 7901364Abstract: A body fluid testing device includes a body member and a tissue penetrator carried by the body member. A test strip holder is carried by the body member, and a test strip is carried by the test strip holder. The test strip is capable of receiving a body fluid thereon and processing the body fluid into a form suitable for yielding test results relating to the content of the body fluid. The body member, tissue penetrator, test strip holder and test strip are designed for a single use and for disposal as a unit without disassembly.Type: GrantFiled: January 5, 2005Date of Patent: March 8, 2011Assignee: Micronix, IncInventors: Hans G. Kloepfer, Reinhard Hafellner, Charles W. Roach, Charles Thomeczek

Patent number: 7901399Abstract: A robotic medical system comprises a medical instrument assembly having a retainer, a serial array of instruments disposed in the retainer, a chamber, and an instrument driver. The robotic medical system further comprises a user interface configured for generating at least one command signal, a drive unit coupled to the first mechanism, second mechanism, and instrument driver, and an electric controller configured, in response to the command signal(s), for directing the drive unit to linearly displace the array of instruments within the retainer, to displace a selected one of the instruments from the retainer into the chamber, and to distally advance the instrument driver within the chamber to engage the selected instrument.Type: GrantFiled: June 13, 2007Date of Patent: March 8, 2011Assignee: Hansen Medical, Inc.Inventor: David L. Brock

Patent number: 7901365Abstract: These and other objects of the present invention are achieved in a body fluid sampling system for use on a tissue site that includes a single drive force generator. A plurality of penetrating members are operatively coupled to the force generator. The force generator moves each of the members along a path out of a housing with a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. A flexible support member couples the penetrating members to define a linear array. The support member is movable and configured to move each of the penetrating members to a launch position associated with the force generator. A user interface is configured to relay at least one of, penetrating member performance or a penetrating member setting.Type: GrantFiled: March 21, 2007Date of Patent: March 8, 2011Assignee: Pelikan Technologies, Inc.Inventors: Dominique Freeman, Dirk Boecker, Don Alden
