Abstract
An improved insertion apparatus simplifies loading of neurovascular device into microcatheter. In one example, the insertion apparatus can include a tapered distal tip, allowing the insertion apparatus to reach the microcatheter with no gap. In another example, the insertion apparatus can include an uneven outer surface along its longitudinal body through laser ablation of material to form protrusions, forming taper features, forming wave patterns or thread extrusions.
Claims10
An insertion apparatus for introducing a neurovascular device into a microcatheter via a rotating hemostasis valve (RHV), the insertion apparatus comprising:
- a longitudinal body defining a lumen therethrough that allows the neurovascular device to pass through, and
- an uneven outer surface preventing a backward movement of the insertion apparatus from the microcatheter when introducing the neurovascular device into the microcatheter wherein the RHV further comprises:
- a seal comprising with a recess formed in the seal;
- and wherein the uneven surface comprises at least one threaded extrusion engaging with the recess formed in the seal of the RHV.
