Abstract

A method for inserting a flexible medical device conduit includes adhering a flexible conduit insertion medical device, with a flexible medical device conduit and an integrated insertion mechanism, to a target site. Moreover, the flexible medical device conduit has an elongated framework formed from a flexible material (e.g., Nitinol) with a body portion, sharp head, distal end and proximal end. The flexible medical device conduit also has a flexible tube at least partially jacketing the elongated framework between the distal end and the proximal end. In addition, the sharp head is disposed at the distal end and is configured for subcutaneous skin insertion and the elongated framework and flexible tube define at least one conduit between the elongated framework and the flexible tube, the conduit having an opening at the distal end. The insertion mechanism is operatively connected to, and integrated with, the flexible medical device conduit and the insertion mechanism is configured to insert a portion of the flexible medical device conduit, including at least the sharp head and the opening, into a user'"'"'s skin target site. The method also includes inserting the flexible medical device conduit into the target site by action of the insertion mechanism.

Claims

1. A method for inserting a flexible medical conduit into a user'"'"'s target site, the method comprising:

adhering a flexible conduit insertion medical device to a target site, the flexible conduit insertion medical device including;

an elongated framework formed from a flexible material, the elongated framework having;

a body portion;

a sharp head;

a distal end; and

a proximal end; and

a flexible tube at least partially jacketing the elongated framework between the distal end and the proximal end,

wherein the sharp head is disposed at the distal end;

wherein the elongated framework and flexible tube define at least one conduit therebetween with at least one opening therealong; and

wherein the sharp head is configured for insertion into a target site; and

an insertion mechanism operatively connected to, and integrated with, the flexible medical device conduit, the insertion mechanism configured to insert a portion of the flexible medical device conduit, including at least the sharp head and the opening, into the skin target site; and

inserting the flexible medical device conduit into the target site by action of the insertion mechanism.

2. The method of claim 1 wherein the inserting step is a subcutaneous insertion of the flexible medical device conduit and the target site is a user'"'"'s skin target site.

3. The method of claim 1 wherein the at least one opening is at the distal end.

4. The method of claim 1 further including the step of:

connecting the proximal end of the flexible medical device conduit to an insulin supply via a connector of the flexible conduit insertion device.

5. The method of claim 1 wherein the adhering step includes adhering a flexible conduit insertion medical device wherein the flexible medical conduit is permanently connected to an insulin supply.

6. The method of claim 1 wherein the insertion step employs a conduit guide of the flexible conduit insertion device to provide anti-buckling support of the flexible medical device conduit during insertion.

7. The method of claim 1 wherein the flexible material is Nitinol.

8. The method of claim 1 wherein the distal end of the flexible medical device conduit is formed to have a no load state curved shape.

9. The method of claim 1 wherein the insertion mechanism includes a guide channel configured for movement of the flexible medical device conduit therethrough during the insertion step.

10. The method of claim 6 wherein the guide channel is configured to provide a flexible medical device conduit deployment angle of approximately 45 degrees with respect to the target site.

11. The method of claim 6 wherein the guide channel is configured to provide a flexible medical device conduit deployment angle of approximately 45 reverse degrees with respect to the target site.

12. The flexible medical conduit insertion device of claim 1 further including a housing that blocks a user'"'"'s view of the flexible medical device conduit.
