TRANSCUTANEOUS MEDICAL DEVICE WITH VARIABLE STIFFNESS
First Claim
1. A transcutaneous analyte sensor, the sensor comprising an in vivo portion adapted for insertion into a host and an ex vivo portion adapted for operable connection to a device that remains external to the host, wherein the in vivo portion of the sensor comprises a first electrode juxtapositioned with a second electrode, wherein the sensor is configured to absorb a relative movement between the in vivo portion and the ex vivo portion.

Abstract
The present invention relates generally to variable stiffness transcutaneous medical devices including a distal portion designed to be more flexible than a proximal portion. The variable stiffness can be provided by a variable pitch in one or more wires of the device, a variable cross-section in one or more wires of the device, and/or a variable hardening and/or softening in one or more wires of the device.

- 1. A transcutaneous analyte sensor, the sensor comprising an in vivo portion adapted for insertion into a host and an ex vivo portion adapted for operable connection to a device that remains external to the host, wherein the in vivo portion of the sensor comprises a first electrode juxtapositioned with a second electrode, wherein the sensor is configured to absorb a relative movement between the in vivo portion and the ex vivo portion.
- 7. A transcutaneous analyte sensor, the sensor comprising an in vivo portion adapted for insertion into a host and an ex vivo portion adapted for operable connection to a device that remains external to the host, wherein the in vivo portion of the sensor comprises a first electrode juxtapositioned with a second electrode, wherein the device comprises a housing adapted for mounting on a skin of a host, wherein the housing comprises electrical contacts configured for operable connection to the sensor wherein the ex vivo portion of the sensor has a preselected stiffness to maintain a stable connection between the sensor and the electrical contacts.
- 13. A transcutaneous analyte sensor, the sensor comprising an in vivo portion adapted for insertion into a host and an ex vivo portion adapted for operable connection to a device that remains external to the host, wherein the in vivo portion of the sensor comprises a first electrode juxtapositioned with a second electrode, wherein the in vivo portion of the sensor has a preselected flexibility to absorb mechanical stresses caused by motion of the host.
- 19. A transcutaneous analyte sensor, the sensor comprising an in vivo portion adapted for insertion into a host and an ex vivo portion adapted for operable connection to a device that remains external to the host, wherein the in vivo portion of the sensor comprises a first electrode juxtapositioned with a second electrode, wherein a stiffness of the ex vivo portion of the sensor is greater than a stiffness of the in vivo portion of the sensor.
