US 2019/0290107 A1 · SHEATH WITH DETECTABLE LEADER

Abstract

Disclosed embodiments include apparatuses, systems, and methods for providing a sheath tip with an angled distal face to conform the sheath to a surface of tissue toward which the sheath is being extended to potentially help reduce or avoid tissue damage upon extending a sheath to convey an elongated instrument for sampling or treatment. In an illustrative embodiment, an apparatus includes a sheath tip positionable at an end of a sheath configured to convey an elongated medical instrument to a location adjacent a detection range of a detecting device. The sheath tip includes a distal member that extends a finite distance beyond the end of the sheath. The distal member is detectable by the detecting device when the end of the sheath is within the finite distance of the detection range of the detecting device.

An apparatus comprising:

a sheath tip positionable at an end of a sheath configured to convey an elongated medical instrument to a location adjacent a detection range of a detecting device, the sheath tip including a distal member that extends a finite distance beyond the end of the sheath, the distal member being detectable by the detecting device when the end of the sheath is within the finite distance of the detection range of the detecting device.

A system comprising:

a sheath defining therein a lumen and configured with an end extendable toward a surface;
an elongated medical instrument configured to be delivered through the lumen in the sheath;
an insertion control system configured to convey the sheath along an axis to a desired location, wherein the insertion control system includes:
a detecting device disposed one of at and adjacent to an end of the insertion control system and having a detection range, and
a first side from which the sheath is configured to be extended along an axis toward a surface;
an instrument control system configured to direct operation of the elongated medial instrument when the elongated medical instrument reaches a desired position;
and
a sheath tip configured to be positioned at an end of the sheath that is configured to convey the elongated medical instrument to the desired location adjacent the detection range of the detecting device, the sheath tip including a distal member that extends a finite distance beyond the end of the sheath, the distal member being detectable by the detecting device when the end of the sheath is within the finite distance of the detection range of the detecting device.
