US 2020/0345212 A1 · ROTATABLE INTRODUCERS

Abstract

Various rotatable shafts and linkage mechanisms configured to allow imaging and access to tissue within a body are provided. In an exemplary embodiment, an introducer system has a rotatable sheath and a linkage that can rotatably engage each other. The rotatable sheath has a distal portion extending at a non-zero angle relative to a proximal portion thereof. The linkage has an exit lumen on its distal end and a plurality of entry lumens on its proximal end. The linkage merges the plurality of entry lumens into the exit lumen, and the exit lumen is aligned with the rotatable sheath upon engagement. Fluid and/or surgical instruments can thus be passed from the plurality of entry lumens of the linkage, through the exit lumen of the linkage, and into the rotatable sheath. The linkage and the rotatable sheath can both receive an imaging device therethrough.

1-48. (canceled)

An imaging system, comprising:

a sheath having a distal end configured to allow imaging therethrough, a proximal end, and only a single lumen extending between the distal and proximal ends, the sheath having an angled distal portion that is angled at a fixed non-zero angle relative to a straight proximal portion of the sheath, the straight proximal portion extending along a longitudinal axis of the sheath, the sheath having a plurality of gripping wings thereon configured to assist in rotation of the sheath, one of the plurality of gripping wings having one or more indicators thereon configured to indicate a direction of the fixed non-zero angle, the one or more indicators comprise a plurality of ribs;
a linkage having distal and proximal sides, the distal side of the linkage being configured to removably operably couple to the proximal end of the sheath, the linkage having a plurality of entry lumens on the proximal side thereof and a single exit lumen on a distal side thereof, the linkage being configured to merge the plurality of entry lumens into the single exit lumen, the linkage having only the single exit lumen on the distal side thereof;
and
an imaging device including a handle and an elongate imaging member extending distally from the handle;
wherein the sheath and the linkage are configured to create an imaging path for the elongate imaging member and a fluid path for fluid from the plurality of entry lumens of the linkage, through the single exit lumen of the linkage, and into the single lumen of the sheath when the distal side of the linkage is operably coupled to the proximal end of the sheath;
and
wherein the linkage is configured to operably couple to the sheath to prevent axial translation and to allow axial rotation between the sheath and the linkage.
