Variable fit lancet
First Claim
1. A lancet comprising a lancet body having a proximal end and a distal end, and a sharp lancing tip extending from the proximal end of the lancet body, the lancet body comprising at least one flexing engagement fin comprising a forward end and a rear end, the at least one flexing engagement fin extending from adjacent the distal end of the lancet body at least to about a midpoint between the proximal and distal ends of the lancet body and being in substantially continuous attachment with the lancet body between the forward and rear ends thereof, wherein the lancet body comprises a longitudinal axis, whereby the at least one flexing engagement fin deforms circumferentially about the lancet body longitudinal axis upon insertion into a receiver of a lancing device.

Abstract
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.

- 1. A lancet comprising a lancet body having a proximal end and a distal end, and a sharp lancing tip extending from the proximal end of the lancet body, the lancet body comprising at least one flexing engagement fin comprising a forward end and a rear end, the at least one flexing engagement fin extending from adjacent the distal end of the lancet body at least to about a midpoint between the proximal and distal ends of the lancet body and being in substantially continuous attachment with the lancet body between the forward and rear ends thereof, wherein the lancet body comprises a longitudinal axis, whereby the at least one flexing engagement fin deforms circumferentially about the lancet body longitudinal axis upon insertion into a receiver of a lancing device.
- 11. A lancet comprising a body having a proximal end and a distal end, and a sharp lancet tip extending from the proximal end of the body, the body having a longitudinal axis, the body of the lancet comprising a plurality of outwardly projecting engagement fins, each of the plurality of outwardly projecting engagement fins having a forward end and a rear end, wherein each engagement fin extends from adjacent the distal end of the lancet body at least to about a midpoint between the proximal and distal ends of the lancet body, each of the plurality of outwardly projecting engagement fins having a base edge and a free edge, the base edge being in substantially continuous attachment with the lancet body between the forward and rear ends of each engagement fin, and the free edge being flexibly movable relative to the base edge between an unflexed state and a flexed state, wherein the free edge is configured to flex circumferentially about the body longitudinal axis, whereby the free edges of the outwardly projecting engagement fins are circumscribable within a first receiver periphery in their unflexed state and are circumscribable within a second receiver periphery in their flexed state, the first receiver periphery defining a first peripheral dimension and the second receiver periphery defining a corresponding second peripheral dimension, the first peripheral dimension being larger than the second peripheral dimension.
- 23. A lancet comprising a body having a proximal end, a distal end, and a longitudinal central core with four flexible engagement fins projecting outwardly therefrom along at least a portion of the central core'"'"'s length, each of the engagement fins having a length extending from adjacent the distal end of the lancet body at least to about a midpoint between the proximal and distal ends of the lancet body, each of the four flexible engagement fins having a root edge continuously attached to the central core along substantially the entire length of the fin and a free edge directed outwardly from the root edge, the root edge defining a first thickness and the free edge defining a second thickness, the first thickness being greater than the second thickness, wherein each of the four flexible engagement fins is configured to deflect circumferentially about the longitudinal central core.
