Adjustable nose cone for a catheter positioning system
Various embodiments enable an introducer for a catheter to be rotated around an axis and/or traversed backward and/or forward along the axis. In various embodiments, positioning of an introducer may be enabled by an introducer support configured to be rotated around an axis and/or extended or retracted along the axis. The introducer may be manually operated and/or operated by motors in a nose cone of a catheter positioning system. In various embodiments, a portion of the introducer support may be configured to flex. In other embodiment, positioning of an introducer may be enabled by an adjustable nose cone of a catheter positioning system.
1. A nose cone configured for supporting an introducer for a catheter positioning system, comprising:
a support portion including a slide arm;
a slide portion configured to slide over a surface of the slide arm to extend along an axis of the nose cone, wherein the surface of the slide arm includes one or more ribs and the slide portion includes a lever having a tooth configured to engage with the one or more ribs to prevent the slide arm from extending along the axis of the nose cone; and
a hollow rotating portion rotationally coupled to the slide portion, an end of the hollow rotating portion comprising a clamp configured to hold the introducer for the catheter positioning system, wherein the hollow rotating portion is configured to rotate the clamp around the axis of the nose cone.
2. The nose cone of claim 1 , wherein the clamp includes a cutout configured to accommodate an irrigation port of the introducer.
3. The nose cone of claim 1 , wherein:
the slide arm and the slide portion are each formed as troughs to accept a catheter; and
the slide portion and the hollow rotating portion each include slots that when aligned enable a catheter body to pass through an outer surface of the hollow rotating portion into a center of the hollow rotating portion, the slide portion, and the slide arm.
4. The nose cone of claim 1 , further comprising:
at least one longitudinal slot extending along a length of the slide portion; and
at least one tab on the support portion configured to travel in the at least one longitudinal slot of the slide portion.
