Publication number: 20080119883Abstract: 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: June 30, 2005Publication date: May 22, 2008Applicant: FACET TECHNOLOGIES, LLCInventors: William E.

Patent number: 7322996Abstract: A lancet having one or more portions of the shank of the lancet blade exposed for direct engagement with cooperating portion(s) of the lancet carrier of a lancing device. This direct engagement of the lancet blade with the lancet carrier provides more precise positional control of the location of the lancing site by eliminating the effect that any variation in the position of the lancet blade within the lancet body would otherwise have on the positioning of the lancet tip. Tolerance stack-up is thereby reduced and accuracy is improved, reducing the necessary sample size and minimizing pain resulting from the lancing operation.Type: GrantFiled: May 30, 2003Date of Patent: January 29, 2008Assignee: Facet Technologies, LLCInventors: William C. Taylor, Richard W. Levaughn, Mitchell Solis, Jeffrey T. Stout

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. Griffin, Avi M. Robbins, Michael V. Lipoma, David R. Buenger

Publication number: 20070233166Abstract: A lancing assembly is pivotally coupled to a housing and includes an actuator and a leaf spring carrying a lancet. When the actuator is in its set position, the leaf spring and lancet are in their set position with the leaf spring engaging a catch member of the housing. When the actuator is moved to its actuated position, the leaf spring pivots and deflects against the catch member, thereby storing a drive charge. The leaf spring then releases from the catch member as the stored charge launches the lancet to its lancing position. The leaf spring recharges towards the end of the lancing stroke, which return charge then retracts the lancet back into the housing.Type: ApplicationFiled: May 26, 2005Publication date: October 4, 2007Applicant: FACET TECHNOLOGIES, LLCInventor: Jeffrey Stout

Publication number: 20070185515Abstract: A lancing device has a housing, an activation/retraction control assembly, and a lancet. The control assembly and the housing have cooperating engagement structures such as detents that disengage after a predetermined launch force is applied to the control assembly. In this way, the lancet is driven to its puncturing position without the use of a drive spring. In addition, the control assembly and the lancet have cooperating releasable engagement structures such as notched sections and tamped protrusions that disengage when the lancet reaches its puncturing position, thereby freeing the lancet from the control assembly. And the control assembly has angled retraction structures that engage the freed lancet to bias it back safely into the housing.Type: ApplicationFiled: June 24, 2005Publication date: August 9, 2007Applicant: FACET TECHNOLOGIES, LLCInventor: Jeffrey Stout
