Description
本願は、その全体が参照により本明細書に組み入れられる、2012年6月6日に出願された米国特許非仮出願第13/490,189号、発明の名称「Bio-implantable Hermetic Integrated Ultra High Density Device」の恩典を主張する。
一般的に、本発明は、生体適合性気密性集積化超高密度(iUHD)集積回路に基づく装置を組み立てるためのシステムおよび方法に関する。
標準的な植え込み型医療装置は典型的にはプリント回路基板に表面実装され、生体に適合する容積で、通常、チタンの入れ物に入れられる。これらの装置はかさばり、身体に対して侵襲性であることが多い。植え込み型医療装置を伴う外科手術は合併症を起こしやすく、患者にリスク、例えば、感染症、アレルギー反応、腫脹、挫傷、出血、装置付近の血管または神経への損傷、または装置の拒絶反応さえも呈する。植え込み型装置が大きな時に、このような合併症のリスクは甚大になる場合がある。従って、これらのリスクを小さくするために小さな生体適合性植え込み型装置を有することが望ましい。さらに、小さな生体適合性植え込み型装置があると移植場所の選択の幅が広がる。大きなインプラントが収まらない部位または高いリスクで合併症を生じさせる部位に小さな植え込み型装置を挿入することができる。
本明細書において開示されたシステムは植え込み型生体適合性集積回路装置を含む。前記装置は、凹みを有する基板を含む。少なくとも1つの生体適合性電気接点を含む入出力装置が凹みの中で基板と連結される。入出力装置の一部の上に生体適合性気密性絶縁体材料の層が付着される。生体適合性材料、例えば、チタンの封止層が、入出力装置の一部を含む植え込み型装置の少なくとも一部を封止する。封止層は、生体適合性でない植え込み型装置の実質的に全ての表面を封止する。入出力装置の少なくとも1つの生体適合性電気接点は封止層を通り抜けて露出される。封止層および生体適合性気密性絶縁体材料の層は少なくとも1つの露出した生体適合性電気接点を取り囲む気密シールを形成する。
[本発明1001]
凹みが中に形成されている基板;
該凹みの中で基板に連結された、少なくとも1つの生体適合性電気接点を備える入出力装置;
入出力装置の一部の上に付着された生体適合性気密性絶縁体材料の層;
植え込み型装置の少なくとも一部を封止する生体適合性材料の封止層であって、
入出力装置の該少なくとも1つの生体適合性電気接点が封止層を通り抜けて露出しており、かつ
封止層および生体適合性気密性絶縁体材料の層が、該少なくとも1つの露出した生体適合性電気接点の周囲に気密シールを形成する、
封止層
を備える、植え込み型生体適合性集積回路装置。
