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： Flexible circuit strips of a catheter balloon may comprise a substrate and a contact electrode disposed on the substrate. A cover may be disposed over a peripheral portion of the contact electrode and an adjacent portion of the substrate The cover is intended to increase robustness of the contact electrode in response to fatigue that might arise from repeated expansion and contraction of the catheter balloon.

摘要： The disclosed technology includes couplers, nose pieces, and strain relief hubs for ablation catheter assemblies and methods of using the same. The disclosed technology can include a medical probe having a coupler having a first portion, a second portion, and a vent port. The second portion can slide between a first position and a second position. When in the first position, the vent port can be at least partially obstructed by the first portion and, when in the second position, the vent port can be unobstructed by the first portion. The medical probe can include a nose piece having an outer diameter of less than 0.14 inches and an aperture extending therethrough. The aperture can be sized to receive a catheter. The medical probe can include a strain relief hub having a first portion and a second portion and configured to be coupled to a handle of the medical probe.
