摘要： A steerable delivery catheter includes an outer sheath with a housing disposed at a distal end thereof to define a chamber for a medical device, the chamber having an open distal end and a proximal inner shelf. An inner shaft is slidably disposed within the sheath and has an abutment attached to the distal end of the shaft, the abutment being slidably contained within the chamber. During navigation of the catheter, when the inner shaft is tensioned the abutment engages the shelf to apply a compressive force to the sheath to selectively deflect a distal region of the catheter. When the catheter has been navigated to the deployment site the sheath is withdrawn while the abutment maintains the medical device in place as it is deployed. A delivery method also is disclosed.

摘要： A catheter for delivering a medical implant in a patient's vasculature includes an elongate catheter having a distensible and frangible cap mounted across the open distal end thereof. The cap is distendable by pressure within the catheter to provide a bumper tip for guiding the catheter through a patient's vasculature. At the desired site for deploying the medical implant, the cap is ruptured to permit the implant to be advanced through the distal opening. Methods of using the catheter are also disclosed.
摘要翻译： 用于将医用植入物输送到患者血管系统中的导管包括细长导管，其具有穿过其开放远端安装的可扩张和易碎的帽。 通过导管内的压力可以使盖膨胀，以提供用于引导导管穿过患者脉管系统的保险杠末端。 在用于部署医用植入物的期望位置处，帽被破裂以允许植入物通过远端开口前进。 还公开了使用导管的方法。
