First Claim
Patent Images
1. An intravaginal device for transmucosal drug delivery comprising:
- a housing shaped and dimensioned for intravaginal deployment and for holding the device in place in the vagina by frictional engagement between the housing and mucosal tissue of a human or animal subject;
a drug-dispensing portion comprising a piston, an actuator, and a drug repository which contains at least one drug;
an electrically-actuatable portion comprising a plurality of electrically-actuatable active disruption elements configured to disrupt at least one region of a mucosal barrier adjacent to the housing at a selected time while intravaginally deployed and retained in the human or animal subject; and
a control module contained in the housing, the control module controlling the active disruption elements and the timing and sequence of the delivery of the drug from the drug repository by activation of the actuator and piston,wherein the device is operable to dispense the drug from the housing to a region of the mucosal barrier disrupted by the electrically-actuatable portion.

Abstract
Intralumenal devices and methods are provided for transmucosal drug delivery. The device may comprise a housing configured for intralumenal deployment into a human or animal subject; a drug-dispensing portion which contains at least one drug; and an electrically-actuatable portion configured to disrupt at least one region of a mucosal barrier adjacent to the housing at a selected time while intralumenally deployed in the human or animal subject. The device may be operable to dispense the drug from the housing to a region of the mucosal barrier disrupted by the electrically-actuatable portion.

11. A method for local transmucosal delivery of a drug to a human or animal subject comprising:
-
deploying and retaining a drug delivery device within a vagina of the human or animal subject, the device comprising a housing configured for holding the device in place in the vagina by frictional engagement with mucosal tissue and an electrically-actuatable portion; actuating the electrically-actuatable portion to disrupt at least one region of a mucosal barrier adjacent to the housing at a selected time following the deployment; and
then after the mucosal barrier has been disrupted,driving a piston in the housing to mechanically displace a drug from a reservoir in the housing, to thereby dispense the drug from the housing to a region of the disrupted mucosal barrier. - View Dependent Claims (12, 13, 14, 15)

16. An intravaginal device for transmucosal drug delivery comprising:
-
a cylindrical housing configured for intravaginal deployment into and retention in a human or animal subject; an electrically-actuatable portion comprising one or more electrically-actuatable active disruption elements configured to disrupt at least one region of a mucosal barrier adjacent to the housing at a selected time while deployed and retained in the vagina of the human or animal subject; a drug dispenser comprising a drug repository containing at least one drug and a piston operable to dispense the at least one drug from the repository through a plurality of orifices or nozzles in the housing and in fluid communication with the repository into the region of the mucosal tissue disrupted by the electrically-actuatable portion; and a control module contained in the housing, the control module controlling the active disruption elements and the timing and sequence of the delivery of the drug from the drug repository by activation of an acutator for the piston. - View Dependent Claims (17, 18, 19, 20, 21)

22. An intravaginal device for transmucosal drug delivery comprising:
-
a cylindrical housing shaped and dimensioned for intravaginal deployment and for holding the device in place in the vagina by frictional engagement between the housing and mucosal tissue of a human or animal subject, the housing having a plurality of dispensing nozzles; an electrically-actuatable portion comprising one or more electrically-actuatable active disruption elements configured to disrupt at least one region of a mucosal barrier adjacent to the housing at a selected time while deployed and retained in the vagina of the human or animal subject, and a drug dispenser comprising a drug repository containing at least one drug, the drug repository being located in the axial center of the housing in fluid communication with the plurality of dispensing nozzles, and a positive displacement element adapted to apply a mechanical force to the at least one drug to dispense the at least one drug from the plurality of dispensing nozzles into the region of the mucosal tissue disrupted by the electrically-actuatable portion. - View Dependent Claims (23, 24)
