Description
本願は、2014年1月15日に出願された米国特許仮出願第61/927,558号及び2014年4月23日に出願された米国出願第14/259,614号に基づく優先権を主張するものである。これらの内容は、参照によりそれらの全体が本明細書に組み込まれる。
図1を参照すると、患者の頭部の第1の図は、本明細書で説明される血管内シャントデバイス及びステントが、患者108の静脈系110のS状静脈洞104の内壁の好ましい配置位置102に送達され得ることを示す。代替的には、本明細書で説明されるシャントデバイス及びステントは、本明細書で開示される他の大径硬膜静脈洞、すなわち、図1に示す横静脈洞、直静脈洞、又は矢状静脈洞に送達され得る。
また、特殊な安定化デバイス及び送達ガイドカテーテルが、患者のS状静脈洞、横静脈洞、直静脈洞、又は矢状静脈洞内への血管内脳脊髄液シャント(eCSFS)デバイスの移植及び安定化を容易にするために展開されてきた。
いくつかの状況では、患者のS状静脈洞又は本明細書で説明される他の洞の壁中に移植されるeCSFSデバイスが、壁から移動して(例えば外れて)、患者のくも膜下腔から脳脊髄液を排液するeCSFSデバイスの能力を損ない得る。いくつかの例では、この問題に対処するために、ステント状デバイスが、前述の洞の壁中にeCSFSデバイスを固定し、展開後のeCSFSデバイスの移動を防止するためのプラットフォームを与えるために使用される。
図7を参照すると、一例のステント700が、自己拡張コイルとして実装され、これはeCSFSデバイス702に結合される。いくつかの例では、eCSFSデバイス702は、中空先鋭状有孔カニューレ703と、流れ制御機構(例えば一方向弁)を備えたプラットフォーム705と、排液チューブ707とを備える。ステント700は、中空先鋭状カニューレ703が、S状静脈洞704の壁を通り、くも膜層706を通り、患者のくも膜下腔708内に挿入された状態で、患者のS状静脈洞704内で展開される。この展開状態では、くも膜下腔708内のCSFが、中空先鋭状カニューレ703の穿孔を通り、プラットフォーム705の流れ調整機構を通り、排液チューブ707から出てS状静脈洞704内へと進む。
図8を参照すると、別の例のステント800が、自己拡張円形バスケットとして実装され、これはeCSFSデバイス802に結合される。いくつかの例では、eCSFSデバイス802は、中空先鋭状有孔カニューレ803と、流れ制御機構(例えば一方向弁)を備えるプラットフォーム805と、排液チューブ807とを備える。ステント800は、中空先鋭状カニューレ803が、S状静脈洞804の壁を通り、くも膜層806を通り、患者のくも膜下腔808内に挿入された状態で、患者のS状静脈洞804内で展開される。この展開状態では、くも膜下腔808内の脳脊髄液が、中空先鋭状カニューレ803の穿孔を通り、プラットフォーム805の流れ調整機構を通り、排液チューブ807から出てS状静脈洞804内へと進む。
図9を参照すると、別の例のステント900が、自己拡張円周型ステントとして実装され、これはeCSFSデバイス902に結合される。いくつかの例では、eCSFSデバイス902は、中空先鋭状有孔カニューレ903と、流れ制御機構(例えば一方向弁)を備えたプラットフォーム905と、排液チューブ907とを備える。ステント900は、中空先鋭状カニューレ903が、S状静脈洞904の壁を通り、くも膜層906を通り、患者のくも膜下腔908内に挿入された状態で、患者のS状静脈洞904内で展開される。この展開状態では、くも膜下腔908内の脳脊髄液が、中空先鋭状カニューレ903の穿孔を通り、プラットフォーム905の流れ調整機構を通り、排液チューブ907から出てS状静脈洞904内へと進む。
図10を参照すると、別の例のステント1000が、1又は2以上の連結部材1012により相互連結されeCSFSデバイス1002に結合された複数の個別のコイル1010を備える自己拡張コイル型ステントとして実装される。いくつかの例では、eCSFSデバイス1002は、中空先鋭状有孔カニューレ1003と、流れ制御機構(例えば一方向弁)を備えるプラットフォーム1005と、排液チューブ1007とを備える。ステント1000は、中空先鋭状カニューレ1003が、S状静脈洞1004の壁部を通り、くも膜層1006を通り、患者のくも膜下腔1008内に挿入された状態で、患者のS状静脈洞1004内で展開される。展開状態では、くも膜下腔1008内の脳脊髄液が、中空先鋭状カニューレ1003の穿孔を通り、プラットフォーム1005の流れ調整機構を通り、排液チューブ1007から出てS状静脈洞1004内へと進む。
いくつかの例では、上述するステントの中の1又は2以上が、ステントに装着されたポート構造部を備える。このポートにより、eCSFSデバイスのカニューレ及び/又は流れ制御機構の後の再配置又は修正が可能となる。すなわち、ステントに案内される安定ポートは、初めにS状静脈洞(又は本明細書で説明される他の洞)と硬膜内くも膜下腔との間に確立される。ポートは、S状静脈洞とくも膜下腔との間に開口穿孔部位を残さずに任意のカニューレ及び/又は流れ制御機構の交換を可能にするために、自己封止ポートを組み込む。いくつかの例では、ポートシステムは、特にカニューレ及び/又は流れ制御機構が交換を必要とする場合に、複数回にわたり繰返し穿孔する必要性を解消する。
いくつかの例では、上述のステントデバイスは、展開中及び/又は展開後にS状静脈洞、横静脈洞、直静脈洞、又は矢状静脈洞の平滑洞内皮層内でのステントの移動を防止する機能を果たす、スロット又は複数の小型返しを備え得る。いくつかの例では、ステントの表面は、その外方壁が、研磨性を有し、展開中及び/又は展開後の平滑内皮層内での滑動を防止するように処理され得る。
上述では、eCSFSデバイスは、コルクスクリュー型頭蓋内態様を有するとして説明される。しかし、デバイスの安全な配置、デバイスの安定性、硬膜及びくも膜の穿通、デバイス展開後のくも膜−硬膜間の並置、並びにデバイスを詰まらせないように脳実質(例えば小脳皮質)の若干の変位を可能にする他の例のeCSFSデバイスが展開されてきた。
図13を参照すると、コルクスクリュー型自己固定式eCSFSデバイス1302(上述のコルクスクリュー形状シャントと同様の)が、コルクスクリュー形状有孔カニューレ1303と、流れ調整機構(図示せず)を備えるプラットフォーム1305と、排液チューブ1307とを備える。その展開状態で、コルクスクリュー形状カニューレ1303は、S状静脈洞壁を通り、くも膜層1306を通り、患者のくも膜下腔1308内に挿入される。脳脊髄液は、コルクスクリュー形状カニューレ1303の穿孔を通り、プラットフォーム1305中の流れ制御機構を通り、排液チューブ1307から流出し、流れ制御機構が脳脊髄液流を制御する。
図14を参照すると、三次元コイル型自己固定式eCSFSデバイス1402は、事前画定された三次元コイル形状を有するコイル状三次元形状有孔マイクロカテーテルチューブ1403のセクションと、流れ調整機構(例えば一方向弁)を備えるプラットフォーム1405と、排液チューブ1407とを備える。展開状態では、有孔チューブ1403は、S状静脈洞壁を通り脳実質1409とくも膜層1406との間の患者のくも膜下腔1408内へと配設される。脳脊髄液は、チューブ1403の穿孔を通り、プラットフォーム1405の流れ制御機構を通り、排液チューブ1407から流出し、流れ調整機構が脳脊髄液流を制御する。
図15を参照すると、傘型自己固定式eCSFSデバイス1502は、有孔中空カニューレ1503を覆う傘形状スクリーン1511と、流れ調整機構(例えば一方向弁)を備えるプラットフォーム1505と、排液チューブ1507とを備える。この展開状態では、有孔中空カニューレ1503及び傘形状スクリーン1511は、S状静脈洞壁を通り脳実質1509とくも膜層1506との間の患者のくも膜下腔1408内へと配設される。脳脊髄液は、カニューレ1503の穿孔を通り、プラットフォーム1505の流れ調整機構を通り、排液チューブ1507から出てS状静脈洞1504内へと流入し、流れ調整機構が脳脊髄液流を制御する。
図16を参照すると、球体型自己固定式eCSFSデバイス1602は、有孔中空カニューレ1603を囲むマルチフィラメント球体状アセンブリ1611と、流れ調整機構(例えば一方向弁)を備えるプラットフォーム1605と、排液チューブ1607とを備える。展開状態では、有孔中空カニューレ1603及びマルチフィラメント球体状アセンブリ1611は、S状静脈洞壁を通り脳実質1609とくも膜層1606との間の患者のくも膜下腔1608内に配設される。脳脊髄液は、カニューレ1603の穿孔を通り、プラットフォーム1605の流れ調整機構を通り、排液チューブ1607から出てS状静脈洞1605内へと流入し、流れ調整機構が脳脊髄液流を制御する。
いくつかの例では、上述のeCSFSデバイスの中の1又は2以上が、自己封止機構を備え、この機構は、洞血液(すなわちS状静脈洞、横静脈洞、直静脈洞、又は矢状静脈洞からの)が、デバイスのプラットフォームの周囲を頭蓋内腔へと流れるのを防止する。例えば、デバイスのプラットフォームは、S状静脈洞壁に対面する表面に形成された溝と、溝内に配設されたヒドロゲルガスケットとを備えてもよい。S状静脈洞血液と接触すると、ヒドロゲルガスケットは膨張して、S状静脈洞血液がプラットフォームの周囲を頭蓋内腔内へと流れるのを防止する気密シールを形成する。
いくつかの例では、eCSFSデバイスの送達は、S状静脈洞、横静脈洞、直静脈洞、又は矢状静脈洞内にeCSFSデバイスを移植するために特に設計されたカテーテル挿入装置を必要とし得る。例えば、対側静脈洞の狭窄又は閉塞を患う患者などの一部の患者は、代替的な静脈通路が損なわれる。これらの患者の場合、例えばガイドカテーテルのバルーンガイドなどによるS状静脈洞の完全な閉塞が、脳組織の静脈脱血を極度に低下させるか又は完全に阻止し得る。eCSFSデバイスを移植するために必要な時間などの長期間にわたる静脈脱血のかかる低下は、患者にとって危険をもたらす恐れがある。
本開示の血管内CSFシャント(eCSFS)デバイス実施形態の例示の寸法が、本明細書で説明される。eCSFSデバイスは、洞血流の途絶及び洞腔内の閉塞を解消する又は最小限に抑えるように寸法設定され構成される。前述のeCSFS展開部位は、これを考慮しつつ選択されている。すなわち、本願で説明される硬膜静脈洞(すなわちS状静脈洞、横静脈洞、直静脈洞、又は矢状静脈洞)は、他の硬膜静脈洞と比較して比較的大きな直径(例えば7mm、8mm、9mm、又はそれ以上)を有することが可能である。この大きな洞直径は、洞内における静脈血流に対する展開手順及び展開されたデバイスの影響を最小限に抑えつつ、本明細書で説明されるようなeCSFSデバイスを収容する。また、特殊なカテーテル挿入装置が開示されたが、これはeCSFS展開中の洞閉塞を最小限に抑えて脳組織の静脈脱血を保護する。
複数の実施形態を説明した。しかし、本開示の主旨及び範囲から逸脱することなく様々な修正をなし得る点を理解されたい。したがって、他の実施形態は、以下の特許請求の範囲内に含まれる。
