  • Sheath stepwise dilation
    Patent number: 11998709
    Abstract: A sheath assembly includes a first sheath, a second sheath, and an attachment mechanism. The first sheath includes a first sheath inner surface defining a first sheath lumen extending along a first sheath central longitudinal axis between a first sheath first end portion and a first sheath second end portion. The second sheath includes a second sheath inner surface defining a second sheath lumen extending along a second sheath longitudinal axis between a second sheath first end portion and a second sheath second end portion. The attachment mechanism couples the second sheath to the first sheath. The attachment mechanism includes an attachment mechanism step-up dilation. At least a portion of the attachment mechanism is asymmetrical, at the attachment mechanism step-up dilation, about the first sheath central longitudinal axis.

  • ADD-ON SHEATH
    Publication number: 20200352598
    Abstract: A sheath assembly includes a first sheath, a second sheath, and an attachment mechanism. The attachment mechanism secures the second sheath to the first sheath such that a first portion of a second sheath outer surface interfaces with a portion of a first sheath outer surface. The second sheath is configured to transition between an expanded state and a collapsed state such that the profile of the sheath assembly can be reduced when the second sheath is in the collapsed state. This can allow the sheath assembly to become more compact, for instance, during insertion, but yet expandable, for instance, once in place within a patient to suitably accommodate an instrument within the second sheath.
