Patent Images
1. An imaging device for identifying subcutaneous tissue structures, the imaging device comprising:
- a housing containing;
a light source configured to illuminate a subcutaneous tissue structure with substantially coherent light;
a sensor module; and
an imaging lens interposed between the subcutaneous tissue structure and the sensor module to focus an image of the subcutaneous tissue structure at the sensor module.

13. A biometric identification device comprising:
-
a light source configured to illuminate a subcutaneous tissue structure of a first individual with substantially coherent infrared light;
a sensor module;
an imaging lens interposed between the subcutaneous tissue structure and the sensor module to focus an image of the subcutaneous tissue structure at the sensor module; and
an image manager including a memory for storing the image associated with a first individual and a comparator for comparing the stored image with at least one record image of a subcutaneous tissue structure associated with at least one other individual to determine whether the stored image substantially matches the at least one record image. - View Dependent Claims (14, 15)

16. A medical instrument system comprising:
-
an imaging device comprising;
a light source configured to illuminate a subcutaneous tissue structure with substantially coherent infrared light;
a sensor module;
an imaging lens interposed between the subcutaneous tissue structure and the sensor module to focus an image of the subcutaneous tissue structure at the sensor module; and
an image manager including a memory for storing the image and a comparator for comparing the stored image with a model image of a target body vessel to determine whether a subject body vessel in the stored image substantially matches the target body vessel in the model image; and
an insertable medical instrument coupled to imaging device, wherein a penetrator of the medical instrument is positionable for insertion into the subject body vessel of the subcutaneous tissue structure when the predefined criteria is met. - View Dependent Claims (17)

18. A method of imaging subcutaneous tissue structures, the method comprising:
-
directing, via a light source, substantially coherent infrared light onto a body portion to illuminate a subcutaneous tissue structure within the body portion;
focusing a first image of the subcutaneous tissue structure from beneath a skin surface onto the sensor module via an imaging lens interposed between the body portion and the sensor module; and
evaluating the first image relative to a predefined criteria to enable performing a function associated with the subcutaneous tissue structure. - View Dependent Claims (19, 20)
