ADJUSTABLE CAP AND LANCING DEVICE AND METHOD OF USE
First Claim
1. A cap for use with a lancing device having a housing and a lancet firing mechanism disposed therein, the cap comprising:
- a cap body having a skin-engaging end that defines a piercing aperture;
a lancet receiver movably mounted in the cap body;
an intermediate member;
a first cam path on one of the lancet receiver and the intermediate member;
a first cam follower on the other of the lancet receiver and the intermediate member that engages the first cam path;
a second cam path on one of the cap body and the intermediate member;
a second cam follower on the other of the cap body and the intermediate member that engages the second cam path; and
an actuating mechanism, wherein the first and second cam paths are configured such that rotation of the intermediate member by the actuating mechanism causes the cap body to move forward and rearward and the lancet receiver to move forward and rearward.

Abstract
Disclosed are cap embodiments each comprising a body having a skin-engaging end defining a piercing aperture, a lancet receiver, and an intermediate member. A first cam path is located on one of the lancet receiver and the intermediate member, and a first cam follower is located on the other of the lancet receiver and the intermediate member that engages the first cam path. A second cam path is located on one of the cap body and the intermediate member, and a second cam follower is located on the other of the cap body and the intermediate member that engages the second cam path. The first and second cam paths are configured such that rotation of the intermediate member by an actuating mechanism causes the cap body to move forward and rearward and the lancet receiver to move forward and rearward. Also disclosed are lancing devices and methods of use.

10. A method of use of a cap of a lancing device having a cap body, a skin-engaging end defining a piercing aperture, an intermediate member and a lancet receiver movably disposed therein, the method comprising:
-
adjusting an effective size of the piercing aperture by moving the lancet receiver between a forward position and a rearward position, wherein an end of the lancet receiver is circumscribed by and is substantially co-planar with the skin-engaging end when the lancet receiver is in the forward position, with the end of the lancet receiver defining the piercing aperture, and the lancet receiver is positioned sufficiently spaced apart from the piercing aperture to permit skin to pucker through the piercing aperture during lancing when in the rearward position; and adjusting a penetration depth of a lancet by moving the cap body forward and rearward when the lancet receiver is in either of the forward and rearward positions, wherein adjusting the effective size comprises moving a first cam follower located on one of the lancet receiver and the intermediate member with an actuating mechanism along a first cam path located on the other of the lancet receiver and the intermediate member, and wherein adjusting the penetration depth comprises moving a second cam follower located on one of the cap body and the intermediate member with the actuation member along a second cam path on the other of the cap body and the intermediate member. - View Dependent Claims (11, 12, 13)

14. A lancing device including a cap having a body, a skin-engaging end defining a piercing aperture, a lancet receiver disposed in the cap, an intermediate cap member, a housing and a lancet firing mechanism disposed in the housing, the lancing device comprising:
-
a first cam path on one of the lancet receiver and the intermediate member; a first cam follower on the other of the lancet receiver and the intermediate member that engages the first cam path; a second cam path on one of the cap body and the intermediate member; a second cam follower on the other of the cap body and the intermediate member that engages the second cam path; and an actuating mechanism, wherein the first and second cam paths are configured such that rotation of the intermediate member by the actuating mechanism causes the cap body to move forward and rearward and the lancet receiver to move forward and rearward. - View Dependent Claims (15, 16, 17, 18, 19, 20)
