Publication number: 20100130997Abstract: A lancing device for sampling blood or other body fluid of a subject includes a reusable housing and a disposable cassette. The cassette contains a plurality of lancets held in a storage plane. An active lancet is moved transversely from the storage plane into a firing plane, into engagement with a drive mechanism for actuation to lance the subject's skin. After actuation, the used lancet is returned to the storage plane. Each lancet includes a protective endcap that is removed from the lancet just prior to use and then is replaced onto the lancet after use.Type: ApplicationFiled: August 19, 2004Publication date: May 27, 2010Applicant: FACET TECHNOLOGIES, LLCInventors: Richard W. LeVaughn, Gwenn E. Kennedy, Christopher J. Ruf, Mitchell A. Solis, Avi M. Robbins, Jason R. Heath, Stephen J. Flynn, Stephanie J. Campbell, Carl E. Griffin, John C. Irwin, Mary Kate Pynes

Publication number: 20100106174Abstract: A medical lancing device including a replaceable multi-lancet cartridge. The lancing device includes a drive mechanism, an activation mechanism, and an advancing mechanism. The advancing mechanism includes a linear-pull slide that is moved in and out to operate an indexing ratchet mechanism, a cam-guided charger mechanism, and a cam-guided lancet cap displacement mechanism. The indexing ratchet mechanism sequentially advances the lancets in the cartridge to an active position. The cam-guided charger mechanism charges the drive mechanism and separates the cap from the active lancet. And the cam-guided cap displacement mechanism moves the separated cap from the lancing stroke path of the active lancet. The activation mechanism then releases the charged active lancet to traverse the unobstructed lancing stroke path to pierce the subject's skin at a desired lancing site.Type: ApplicationFiled: December 29, 2009Publication date: April 29, 2010Applicant: FACET TECHNOLOGIES, LLCInventors: William E.

Patent number: 7655019Abstract: 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: GrantFiled: August 19, 2004Date of Patent: February 2, 2010Assignee: Facet Technologies, LLCInventors: Richard W.

Patent number: 7377904Abstract: 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: GrantFiled: April 15, 2005Date of Patent: May 27, 2008Assignee: Facet Technologies, LLCInventors: William E.
