Heart valve treatment member with variable orientation

A device (30) for fragmenting calcification in a heart valve includes a first heart valve treatment member (12) extending from a first shaft (20) and including a score (16). A second heart valve treatment member (32) extends from the second shaft (36) and has a reaction force member (34). The second heart valve treatment member (32) and the reaction force member (34) are coupled to the second shaft (36) by a stent (35) arranged to withstand a force applied to the reaction force member (34) by the score (16). 用于使心瓣中的钙化物破碎的装置(30)包括第一心瓣治疗构件(12)，第一心瓣治疗构件从第一轴(20)延伸且包括刻划部(16)。第二心瓣治疗构件(32)从第二轴(36)延伸且具有反作用力构件(34)。第二心瓣治疗构件(32)和反作用力构件(34)通过支架(35)联接到第二轴(36)，支架(35)被布置成承受由刻划部(16)施加到反作用力构件(34)的力。
