  • Publication number: 20190184136
    Abstract: Methods, apparatuses and systems are described for providing access to a body lumen. The access system may include an access catheter with a lumen extending from a proximal end to a distal end of the access catheter and a stylet configured to fit within the lumen of the access catheter. The stylet may include a lumen extending from a proximal end to a distal end of the stylet and a piercing tip at the distal end of the stylet configured to protrude from the distal end of the access catheter. The access system may be advanced adjacent to the body lumen and the piercing tip of the stylet may pierce the wall of the body lumen by advancing the stylet and the access catheter together.

  • Publication number: 20180271592
    Abstract: Methods, systems, and devices for providing treatment to a tissue in body lumens are described. The system may include a catheter, an expansion member coupled with a distal portion of the catheter, an ablation structure including one or more longitudinal electrode segments, and an ablation structure support coupled to the ablation structure configured to at least partially unfurl as the expansion member expands and furl as the expansion member contracts. The ablation structure may include multiple separately wired and/or separately controlled longitudinal electrodes, longitudinal electrode zones, or both, such that each longitudinal electrode or longitudinal electrode zone may be selectively enabled or selectively disabled. In some instances, one or more springs are coupled to the ablation structure configured to promote unfurl or furl around the expansion member. In some instances, one or more protection elements are be positioned along the catheter.

  • Publication number: 20160361088
    Abstract: Methods, apparatuses, and systems are described for accessing a body lumen for subsequent treatment thereof. Systems include a cannula configured to penetrate a wall of a body lumen and to passively transition to a nonlinear shape within the body lumen as an elongate member is withdrawn from the distal section of the cannula. Other embodiments include a handle, a cannula removably disposed within a lumen of the handle, and a penetration member sized to advance through a lumen of the cannula, the cannula configured to passively transition to a nonlinear shape as the penetration member is withdrawn from a distal section of the cannula, and a cannula hub configured to selectively engage with a proximal end of the handle to selectively lock rotational movement of the cannula with respect to the handle.
