Apparatus for modifying tissue in a patient may include: an elongate, at least partially flexible body having a proximal portion and a distal portion; a tissue modifying member disposed along one side of the body; an atraumatic surface located adjacent the tissue modifying member; an actuator coupled with the tissue modifying member and extending to the proximal portion of the body; and means at or near the proximal and distal portions of the elongate body for facilitating application of tensioning and/or anchoring force to urge the tissue modifying member against the target tissue. In some embodiments, a flexible portion of the elongate body may be configured to extend through an intervertebral foramen of the patient's spine while the proximal and distal portions of the device extend out of the patient, and the tissue modifying member may be configured to remove soft tissue and/or bone to treat or alleviate spinal stenosis.
L'invention porte sur un appareil permettant de modifier un tissu d'un patient et pouvant comprendre: un corps allongé, au moins partiellement flexible, pourvu d'une partie proximale et d'une partie distale; un élément de modification des tissus disposé le long d'un côté du corps; une surface atraumatique adjacente à l'élément de modification des tissus; un actionneur couplé audit élément de modification des tissus et s'étendant vers la partie proximale du corps; et un moyen placé au niveau ou à côté des parties proximale et distale et visant à faciliter l'application d'une force de tensionnement et/ou d'ancrage afin de pousser l'élément de modification des tissus contre le tissu cible. Selon certaines formes d'exécution, une partie flexible du corps allongé peut être configurée de façon à s'étendre dans un foramen intervertébral de la colonne vertébrale du patient, alors que les parties proximale et distale du dispositif s'étendent hors du corps du patient, et l'élément de modification des tissus peut être configuré de façon à retirer le tissu mou et/ou l'os pour traiter ou soulager la sténose vertébrale.
