Microdevice and method of manufacturing a microdevice
First Claim
1. A method of forming a microdevice for delivering or withdrawing a substance through the skin of a patient, comprising the steps of:
- providing a support having a bottom face with a recessed area having a dimension less than a dimension of said bottom face, positioning a skin penetrating device in said recessed area of said support, said skin penetrating device having a base and at least one skin penetrating member, said base having a dimension less than said dimension of said recessed area, and applying a bonding amount of a bonding agent to at least one location between said support and said base in said recessed area, said bonding agent having a viscosity to wick between said base and said support.

Abstract
A device for monitoring, sampling or delivering a substance though the skin of a patient includes a support and a microdevice having at least one skin penetrating member. The support has a substantially flat bottom surface with the skin penetrating member extending beyond the bottom surface. An outlet port extends through the support to the bottom surface at a location between the skin penetrating member and the outer edge of the support for drawing a vacuum to enhance penetration of the skin. The device is produced by positioning the microdevice in a recess formed in the support and applying a bonding agent to wick into a gap formed between the microdevice and the wall of the recess.

16. A method of withdrawing a substance or delivering a substance through the skin of a patient, said method comprising providing a support having a central passage, a bottom face, a one skin penetrating device on said bottom face, said central passage being in communication with said skin penetrating device,
positioning said support on the skin of a patient with said bottom face of said support and said at least one skin penetrating device contacting said skin, reducing the pressure in an area between said support and said skin to draw said skin toward said skin penetrating member and to cause said skin penetrating device to penetrate said skin, and withdrawing or delivering a substance through the skin of said patient.

24. A device for delivering or withdrawing a substance from a patient, said device comprising:
-
a support member having a bottom face and a recessed area having a dimension less than a dimension of said bottom face, a skin penetrating device having a base and at least one skin penetrating member, said base being positioned within said recessed area of said support, and a bonding material attaching said skin penetrating device to said support member and filling a space between said recessed area and said base of said skin penetrating device.

39. A device for delivering or withdrawing a substance from a patient, said device comprising:
-
a support member having a bottom face, an outer edge, and a recessed area having a dimension less than a dimension of said bottom face, said support having at least one passage communicating with said bottom face between said recessed area and said outer edge, a skin penetrating device having a base and at least one skin penetrating member, said base being positioned within said recessed area and coupled to said support.

44. A method of forming a microdevice, comprising the steps of:
-
providing a support having a bottom face with a recessed area having a dimension less than a dimension of said bottom face and at least one channel with said recessed area, positioning a microdevice in said recessed area of said support, said microdevice having a base with a dimension less than said dimension of said recessed area, and applying a bonding amount of a bonding agent to said channel, said bonding agent having a viscosity to wick along said channel and between said base and said support. - View Dependent Claims (45, 46)
