Physiological sample collection devices and methods of using the same
First Claim
1. A lance element for attachment to a test strip to access body fluid and convey it to a test strip sensor, said lance comprising:
- a substantially planar base;
a piercing element comprising an opening occupying a substantial portion of a width, diameter or length dimension of said piercing element; and
a fluid pathway in communication with said opening, wherein a pooling area is created within the skin by said opening upon insertion of said piercing element into the skin of a subject.

Abstract
Devices, systems and methods are provided for piercing the skin, accessing and collecting physiological sample therein, and measuring a characteristic, e.g., an analyte concentration, of the sampled physiological sample. The subject devices are in the form of a test strip that include a biosensor and at least one skin-piercing element affixed to the test strip. The skin-piercing element conveys a biological fluid sample to a sensor element in the test strip. Systems are provided which include one or more test strip devices and a meter for making analyte concentration measurements. Methods for manufacturing and using the devices and systems are also provided.
