    摘要: Delivery systems (100, 200, 300, 400, 500) including a delivery device (130, 230, 330, 430, 530) having a catheter (132, 133, 232, 233, 332, 333, 432, 433, 532) and a stabilization device (150, 250, 350, 450, 550), the delivery device configured for delivering an apparatus to a left atrium (20) of a patient via the patient's vasculature. The stabilization device has a delivery position in which the stabilization device is collapsed against the catheter and a deployed position in which the stabilization device expands to engage and support the catheter within the vasculature, for example, within the vena cava (14) proximate the right atrium (16). In various embodiments, the delivery device functions as an introducer though which a second delivery device carrying the apparatus is inserted. Methods of accessing the left atrium with the delivery systems and devices are also disclosed.

    摘要:  被験者の体内にシース1を挿入した状態で、袋部材4がシース1の先端より前方へ突出するまでシース1を外筒2に対して相対的に後退させる操作を行った後、外筒2を通して袋部材4の中に治療用物質を充填する操作を行うと共に内筒3を通して拡張部材5の中に拡張用物質を充填する操作を行い、拡張部材5を内筒3の先端から取り外すと共に袋部材4を外筒2の先端から取り外すことにより、拡張した状態の拡張部材5と治療用物質を内部に収容した袋状部材4を被験者の体内に留置させる。

    摘要: A catheter device is disclosed for transvascular delivery of a medical device to a cardiac valve region of a patient. The catheter device comprises an elongate sheath (2) with releasable locking members for controllably locking the elongate sheath in a shape at least partly along its length from a relaxed state to a locked state when positioned in relation to a cardiac valve. Furthermore, alignment members (5) are provided to provide for a desired positioning in relation to the cardiac valve. Embolic protection (8) is further provided.

    摘要: A valvuloplasty catheter has a dog-bone shaped balloon with semi-compliant smaller diameter waist and non-compliant larger diameter bulbous end regions. The balloon centers across the valve with the waist adjacent to the annulus. One bulbous region serves to hyperextend the valve leaflets and the other assists in stabilizing the balloon position to reduce migration. The semi-compliant waist increases in diameter as fluid enters the balloon until it comes into contact with the valve annulus. The pressure within the balloon per unit of volume delivery has a greater slope after contact with the annulus than before resulting in a change in slope for the pressure versus volume curve. The diameter of the balloon and annulus are determined at this inflection point when the balloon contacts the annulus.
