    摘要： A balloon of a balloon catheter must be able to withstand fatigue to its componentry caused by multiple cycles of repeat motions, such as deployment from a lumen of the catheter, expanding the balloon, collapsing the balloon, and withdrawal of the balloon into the lumen. The catheter balloon may include plurality of electrode substrates, each including a plurality of tails. A reinforcement component, which may be a portion of another balloon, may be disposed over at least some of the plurality of tails and attached to the membrane. Where tails are provided on the proximal and distal ends of the balloon, two reinforcement mechanisms may be used.

    摘要： The disclosed technology includes a hemostasis valve assembly comprising an elongate body with a first valve disposed near the proximal end and a second valve disposed near the distal end and spaced apart from the first valve. The first valve can allow a member to extend through the first valve and the second valve can allow the member to extend through the second valve. The elongate body can define a cavity comprising a sloped portion including a first distance between an inner surface of the elongate body and the longitudinal axis near the distal end that is greater than a distance between the inner surface and the longitudinal axis near the proximal end such that a gas is directed along the sloped portion to accumulate at an accumulation region in the cavity near the distal end when a member extends through the first valve.

    摘要： Examples presented herein illustrate various end effector designs with multiple spines that can expand from a collapsed configuration as the end effector traverses vasculature to an expanded configuration when the end effector is at a treatment site. In some examples, the end effector includes three frame loops which each include a pair of spines. At least one of the three frame-loops can have a bend at a distal end of the end effector so that the spines of the frame loop are not directly opposite each other with respect to the longitudinal axis. In some examples, the end effector includes an inner and an outer frame, each having multiple spines and configured such that one or both of the frames can rotate from an aligned configuration to an unaligned configuration.
