Publication number: 20080065134Abstract: A medical lancing device including a replaceable multi-lancet cartridge. The lancing device includes an advancing mechanism that advances lancets within the cartridge into an active position, separates a protective cap from the active lancet, and energize a drive mechanism of the lancing device. A cap displacement mechanism moves the separated cap out of the travel path of the active lancet. In a first example embodiment, the cap displacement mechanism includes a cantilevered spring arm that displaces the detached cap of the active lancet. In a second example embodiment, the cap displacement mechanism includes a spring-biased cam-driven plunger that displaces the detached cap of the active lancet. Then an activation mechanism releases the energized active lancet to traverse the unobstructed lancing stroke path to pierce the subject's skin at a desired lancing site.Type: ApplicationFiled: October 31, 2007Publication date: March 13, 2008Inventors: William Conway, Christopher Ruf, John Irwin, Stephen Flynn, Avi Robbins, Brian Vanhiel, Brian Leutz, Richard LeVaughn, Michael Lipoma

Publication number: 20070255300Abstract: A low-pain lancing device includes a drive mechanism for loosely engaging a lancet and driving the lancet along an axial path. The drive mechanism has a first coupling element and the lancet has a second coupling element, which together form a loose coupling therebetween, wherein interaction between the first and second coupling elements permits a degree of freedom of movement between the lancet and the drive mechanism in a lateral direction, perpendicular to the axial path of travel of the lancet, to prevent non-axial movement of the lancet tip during lancing and thereby reduce pain experienced by the subject.Type: ApplicationFiled: January 3, 2007Publication date: November 1, 2007Applicant: FACET TECHNOLOGIES, LLCInventors: Brian VANHIEL, Bradley KOEPPEL, William CONWAY, Christopher RUF, John IRWIN, Avi ROBBINS, Ray LATHROP

Publication number: 20060235454Abstract: A sampling device (20) having a housing (24) with a lancet cartridge (22) mounted therein. The lancets (26) of the lancet cartridge (22) are interconnected by a flexible web (28). The lancet cartridge (22) is not positively engaged within the housing (24) and can be easily removed. The housing (24) has an opening (42) with an adjacent flexible or compressible fin (60) for dampening the motion of the lancet (26). The lancet cartridge (22) has at least one lancet (26) with an endcap, and the housing has a cap-removal mechanism (74) for separating the endcap from the housing (24). Anti-tampering features prevent opening of the device when the lancet cartridge (22) is oriented with a lancet (26) in a firing position.Type: ApplicationFiled: August 19, 2004Publication date: October 19, 2006Inventors: Richard LeVaughn, Gwenn Kennedy, Stephen Flynn, Carl Griffin, John Irwin, Mary Pynes, Stephanie Campbell, Christopher Ruf, Mitchell Solis, Avi Robbins, Jason Heath

Publication number: 20060224172Abstract: A sampling device having a lancing apparatus, and optionally a detector and a meter. The lancing apparatus includes a replaceable cartridge of lancets, each lancet having an independent arming and drive mechanism enabling non-sequential and/or simultaneous firing of lancets. A lancet retainer independently associated with each lancet is movable to uncover an opening through which the lancet tip passes, and to release the lancet for activation. The lancets can be actuated in any order, and multiple lancets can be simultaneously actuated, if desired.Type: ApplicationFiled: August 19, 2004Publication date: October 5, 2006Applicant: Facet Technologies, LLCInventors: Richard LeVaughn, Gwenn Kennedy, Stephen Flynn, Carl Griffin, John Irwin, Mary Pynes, Stephanie Campbell, Christopher Ruf, Mitchell Solis, Avi Robbins, Jason Heath
