Device for subcutaneous delivery of fluid medicament
First Claim
1. A vial adapter for use with a device for delivering a fluid medicament to subcutaneous tissue of a user, the device comprising a reservoir having a fill septum and configured to contain the fluid medicament, the vial adapter comprising:
- a housing forming;
a first port detachably fluidically connectable to the reservoir; and
a second port detachably fluidically connectable to a vial having a vial septum;
a hollow needle configured to pierce the fill septum and the vial septum to create a fluidic path between the vial and the reservoir for transferring the fluid medicament between the vial and the reservoir; and
a floating part captured within the housing and disposed between the first port and the second port, wherein the floating part fixedly holds the hollow needle while clearance between the floating part and the housing enables relative movement of the floating part in its entirety, wherein the floating part enables the hollow needle to move perpendicularly to an axis of the hollow needle.

Abstract
The application is directed to a vial adapter for attaching a medicament vial to a medicament delivery device having a reservoir adapted to receive and contain the medicament. The vial adapter can include a housing with two ports (one for attaching the reservoir and the other for attaching to the vial), a hollow needle that pierces septums sealing each of the reservoir and the vial, and a floating part that fixedly holds the hollow needle. Clearance between the floating part and the housing can enable relative movement of the floating part.

11. A method for filling a reservoir of a medicament delivering device with fluid medicament using a vial adapter comprising a housing that forms a first port and a second port, a hollow needle, and a floating part fixedly holding the hollow needle captured within the housing and disposed between the first port and the second port, the method comprising the steps of:
-
connecting the first port of the vial adapter to the reservoir by piercing a filling septum of the reservoir with the hollow needle;
connecting the second port of the vial adapter to a vial containing the fluid medicament by piercing a vial septum of the vial with the hollow needle,wherein clearance between the floating part and the housing enables (i) relative movement of the floating part in its entirety and (ii) the hollow needle to move perpendicularly to an axis of the hollow needle, and wherein when the first and second port of the vial adapter are respectively connected to the reservoir and to the vial, the hollow needle fluidically couples the vial to the reservoir.

12. A filling system comprising:
-
a device for delivering a fluid medicament to subcutaneous tissue of a user, the device comprising a reservoir for receiving and containing the fluid medicament; a vial adapter comprising; a housing forming; a first port connectable to the reservoir, and a second port connectable to a medicament vial containing the fluid medicament; and a needle disposed in the first port and the second port, wherein when the vial adapter is connected to the reservoir and to the medicament vial, the needle fluidically couples the medicament vial with the reservoir; and a floating part captured within the housing and disposed between the first port and the second port, wherein the floating part fixedly holds the needle while clearance between the floating part and the housing enables relative movement of the floating part in its entirety, wherein the floating part enables the needle to move perpendicularly to an axis of the needle. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
