Ingestible electronic capsule and in vivo drug delivery or diagnostic system

摘要

An ingestible electronic capsule (100) for introduction into the bodily lumen comprises a circuit board with at least one electronic component (4, 5, 7, 8, 9, 11, 12, 13, 14). The circuit board is formed from a flex foil (10), thereby reducing the number of components and improving the robustness and reliability of the ingestible electronic capsule (100).

主权项

1. An ingestible electronic capsule for introduction into a bodily lumen, comprising:
a housing; a continuous flex foil formed of a uniform material and having a first portion extending generally in a longitudinal direction, the flex foil further having a second portion that extends from the first portion at an angle relative to the longitudinal direction;
an electrically conducting layer integrated into the second portion; a plurality of electronic components disposed directly on the flex foil and spaced from each other along the longitudinal direction on the first portion, the continuous flex foil being bent along at least one bend line disposed in the lateral direction between adjacent electronic components to form a bent flex foil and the second portion being bent relative to the first portion; a reservoir sealed relative to the first portion of the housing, the reservoir containing a drug for expulsion from the capsule via a dispensing hole; and a release mechanism movable to empty the drug through the dispensing hole, the release mechanism being electrically connected to at least one of the plurality of electronic components formed on the flex foil.
