摘要： The disclosed technology includes a medical probe comprising a tubular shaft having a proximal end and a distal end, the tubular shaft extending along a longitudinal axis. The medical probe further comprises an expandable basket assembly coupled to the distal end of the tubular shaft. The basket assembly includes a plurality of electrodes with each electrode of the plurality of electrodes having a lumen therethrough. The basket assembly further includes a plurality of spines extending along the longitudinal axis and configured to bow radially outward from the longitudinal axis when the expandable basket assembly is transitioned from a collapsed form to an expanded form. Each spine includes a proximal and a distal end and a strut passing through the lumen of an electrode. The strut includes a mechanical retainer disposed on the strut to prevent the electrode from sliding proximally or distally along a length of the spine.

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.
