Abstract
Abstract An apparatus for implantation of in vivo sensors includes a housing, a dual-lumen tube extending therefrom, and an in vivo sensor received within one of the lumen of the tube. A needle is received within the other lumens of the tube, and is used to insert the tube through the skin. After implantation, the needle is removed, and the flexible tube and sensor remaining beneath the skin provides the user with reduced irritation and greater comfort. The associated method for subcutaneous implantation of a sensor for use in vivo is also disclosed.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
156 words
An apparatus for implantation of a sensor beneath the skin surface which comprises: a housing; a dual-lumen tube having a proximal end attached to said housing and having a distal end projecting from said housing, said tube, including the distal end, defining a first lumen and a second lumen; a needle received within the first lumen of said tube, said needle including a proximal end and a pointed distal end extending outwardly of the distal end of said tube; and a sensor received within the second lumen of said tube, said sensor including a sensing element positioned within the second lumen adjacent the distal end of said tube and outside of said housing, said sensor further including means for communicating information sensed by the sensing element to a location spaced from the sensing element, whereby implantation of said sensor is accomplished by forcing said needle and said tube into a desired location beneath the skin surface,
Claim 2
Independent Claim
156 words
An apparatus for implantation of a sensor beneath the skin surface which comprises: a housing; a dual-lumen tube having a proximal end attached to said housing and having a distal end projecting from said housing, said tube, including the distal end, defining a first lumen and a second lumen; a needle received within the first lumen of said tube, said needle including a proximal end and a pointed distal end extending outwardly of the distal end of said tube; and a sensor received within the second lumen of said tube, said sensor including a sensing element positioned within the second lumen adjacent the distal end of said tube and outside of said housing, said sensor further including means for communicating information sensed by the sensing element to a location spaced from the sensing element, whereby implantation of said sensor is accomplished by forcing said needle and said tube into a desired location beneath the skin surface,
Claim 3
Dependent Claim
13 words
The apparatus of claim 1 in which said sensor is a glucose sensor.
Claim 4
Dependent Claim
31 words
