  • Publication number: 20250135107
    Abstract: Embodiments provide swallowable devices, preparations and methods for delivering drugs and other therapeutic agents within the GI tract. Particular embodiments provide a swallowable device such as a capsule for delivering drugs into the intestinal wall or other GI lumen. Embodiments also provide various drug preparations that are configured to be contained within the capsule, advanced from the capsule into the intestinal wall and degrade within the wall to release the drug to produce a therapeutic effect. The preparation can be coupled to a delivery mechanism having one or more balloons or other expandable devices which are expandable responsive to a condition in the small intestine or other GI lumen to advance the preparation out of the capsule into the intestinal wall. Embodiments are particularly useful for the delivery of drugs which are poorly absorbed, tolerated and/or degraded within the GI tract.

  • Publication number: 20250057209
    Abstract: There is provided a smoking material wrapper having micropores, wherein when the smoking material wrapper is divided into three regions at equal intervals from an upstream distal end based on the case where the smoking material wrapper is applied to a smoking article, an average porosity is greater as a region becomes closer to a downstream. According to an embodiment of the present disclosure, the micropores have a pore size of 10 ?m to 50 ?m, and are formed by a perforation method using plasma. The wrapper may maintain functionality as a wrapping material due to low visibility or the like, and may minimize a dilution ratio decreased due to burning of a smoking material unit while maintaining a basic dilution ratio when the smoking material wrapper is applied to a smoking article.
