Embodiment Construction

[0022]

[0023] A transmucosal drug delivery device for intralumenal deployment is provided. As used herein, the term "intraluminal" refers to a device placed within a body cavity, passage, duct, etc. that has a wall of mucosal tissue. The term includes, but is not limited to, intravaginal, intrauterine, and intragastrointestinal sites. Insertion or placement of the device within the lumen is typically maintained during delivery of at least one or more doses of drug. The implanted device can be withdrawn from the lumen as needed, including, for example, between delivery of individual doses, after delivery of several doses of drug, or after completion of a series of multi-dose treatments. The device can be left in place until the drug payload is consumed.

[0024] In some embodiments, a transmucosal drug delivery device includes (i) a housing configured to allow insertion within a lumen, (ii) one or more reservoirs for containing a drug, and (iii) a plurality of reservoirs e...

Abstract

The invention discloses a transmucosal medicine conveying device comprising micro needles and a transmucosal medicine conveying method. The device comprises a case, a medicine distribution part and a plurality of micro needles, wherein the case is configured and is used for placing human or animal subjects in a cavity, the medicine distribution part is used for accommodating at least one kind of medicine, the micro needles extend out from the case or can extend out from the case, and the micro needles are configured to a state that after the human or animal subjects are placed in the cavity, at least one region of a mucosa blocking layer adjacent to the case is damaged in the selected time. The device can be operated so that the medicine is distributed to the region of the mucosa blocking layer damaged by the micro needles.

Description

technical field [0001] Embodiments disclosed herein relate to implantable medical devices, and more particularly to devices and methods for transmucosal delivery of drugs to a patient. Background technique [0002] Transmucosal drug delivery is an area of ​​interest because it is possible to deliver systemically acting drugs with high relative bioavailability by avoiding first-pass metabolism effects, possibly to the target of interest. The therapeutic agent is delivered locally at the site, and the route of administration is convenient. Some possible sites for transmucosal drug delivery include oral, nasal, vaginal and rectal routes of administration. [0003] There are a number of challenges associated with transmucosal drug delivery, especially the transmucosal delivery of macromolecules including certain amino acid sequences. Enzymes present in fluid secreted by mucosal tissues break down certain amino acids. The types of enzymes presented by mucosal tissue vary accor...
