Patent number: 8721672Abstract: A lancet having a lancet body and a sharp lancing tip extending from the lancet body, the lancet body including at least one flexing engagement fin, which is resiliently deformable upon insertion into a receiver of a lancing device. The outer dimension of the lancet effectively self-adjusts to conform to a wide range of receiver inner dimensions, and as such, the lancet of the present invention enables universal application with a larger range of lancing devices than previously known lancets.Type: GrantFiled: July 1, 2008Date of Patent: May 13, 2014Assignee: Facet Technologies, LLCInventors: Jeffrey T. Stout, Michael V. Lipoma, Christopher J. Ruf

Publication number: 20130289598Abstract: 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: June 27, 2013Publication date: October 31, 2013Inventors: William E. Conway, Christopher J. Ruf, John C. Irwin, Stephen J. Flynn, Avi M. Robbins, Brian D. VANHIEL, Brian D. LEUTZ, Richard W. LeVAUGHN, Michael V. LIPOMA

Patent number: 8366729Abstract: A lancing device and method for self-collecting a sample of body fluid by penetrating a body tissue at a sampling site. The invention includes a housing geometry configured for ease of use at different sampling sites on the body, even by persons having reduced dexterity and/or poor vision. Depth of penetration is selectively controlled by adjusting the stroke range of a spring-driven lancet carrier. A pressure applicator is included for stimulating flow of the body fluid. A transparent portion permits observation of the sampling site.Type: GrantFiled: July 31, 2007Date of Patent: February 5, 2013Assignee: Abbott Diabetes Care Inc.Inventors: Richard W. Levaughn, Stephen J. Flynn, Gwenn E. Kennedy, Michael V. Lipoma

Patent number: 7837633Abstract: 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: GrantFiled: June 30, 2005Date of Patent: November 23, 2010Assignee: Facet Technologies, LLCInventors: William E.

Patent number: 7288102Abstract: A lancing device having a low-mass, high-velocity lancet decoupled from a drive mechanism when piercing a user's skin. The drive mechanism includes a spring-driven piston that impacts the lancet on firing to propel the lancet from a retracted position towards an extended position. After impact, but before the lancet reaches the extended position, a stop limits the travel of the piston to separate the piston from the lancet. Precise guidance of the lancet minimizes lateral movement of the lancet.Type: GrantFiled: March 22, 2004Date of Patent: October 30, 2007Assignee: Facet Technologies, LLCInventors: Carl E.
