Drug delivery devices, systems, and methods
First Claim
1. A drug delivery device, comprising:
- an elongate member defining a fluid passage and an opening in fluid communication with the fluid passage;
an introducer needle disposable within the elongate member for insertion of the elongate member into a patient'"'"'s skin; and
a projection extending radially from the elongate member,wherein a portion of the elongate member extending axially from the projection to a distal end of the elongate member has a length sufficient to allow the distal end of the elongate member to reach subdermal tissue of a patient when the elongate member is inserted into the patient and the projection is in contact with an outer surface of skin of the patient, and the opening is positioned at a location along the elongate member such that the opening is disposed within a dermis of the patient when the elongate member is inserted into the patient and the projection is in contact with the outer surface of the skin of the patient; and
wherein a portion of the elongate member between the opening and the distal end of the elongate member comprises a self-sealing material to seal the distal end of the elongate member subsequent to removal of the introducer needle.

Abstract
This disclosure relates to drug delivery devices, systems, and methods. In some aspects, a drug delivery device includes an elongate member defining a fluid passage and an opening in fluid communication with the fluid passage, and a projection extending radially from the elongate member. A portion of the elongate member extending axially from the projection to a distal end of the elongate member has a length sufficient to allow the distal end of the elongate member to reach subdermal tissue of a patient when the elongate member is inserted into the patient and the projection is in contact with an outer surface of skin of the patient, and the opening is positioned at a location along the elongate member such that the opening is disposed within a dermis of the patient when the elongate member is inserted into the patient and the projection is in contact with the outer surface of the skin of the patient.

16. A drug delivery device, comprising:
-
an elongate member defining a fluid passage and an opening in fluid communication with the fluid passage; an introducer needle disposable within the elongate member for insertion of the elongate member into a patient'"'"'s skin; and a projection extending radially from the elongate member, wherein a portion of the elongate member extending axially from the projection to a distal end of the elongate member has a length sufficient to allow the distal end of the elongate member to reach subdermal tissue of a patient when the elongate member is inserted into the patient and the projection is in contact with an outer surface of skin of the patient, and the opening is positioned at a location along the elongate member such that the opening is disposed within a dermis of the patient when the elongate member is inserted into the patient and the projection is in contact with the outer surface of the skin of the patient; and wherein a portion of the elongate member between the opening and the distal end of the elongate member comprises a valve to seal the distal end of the elongate member subsequent to removal of the introducer needle.

17. A drug delivery device, comprising:
-
an elongate member having a fluid passage; an introducer needle insertable within the elongate member to assist in insertion of the elongate member into a patient'"'"'s skin; and a projection that extends radially from the elongate member and that contacts the skin and limits the depth of the insertion of the distal end of the elongate member to the level of subdermal tissue; wherein the elongate member has an opening along the fluid passage that is located at a dermis level of the tissue while the projection is contacting the skin; and wherein the device further comprises a valve disposed in the elongate member between the distal end and the opening of the elongate member.
