摘要： Disclosed embodiments include apparatuses, systems, and methods for providing an atraumatic sheath tip. Various disclosed embodiments seek to help reduce or avoid unnecessary tissue damage upon a sheath being extended to convey an elongated instrument for sampling or treatment. In an illustrative embodiment, an apparatus includes a deformable sheath tip configured to be positioned at a distal end of a sheath. The sheath defines therein a lumen configured to convey an elongated instrument. The sheath tip has a base end disposable at the distal end of the sheath and a contact end. The sheath tip has a first column strength along an axis of the sheath tip that is less than a second column strength of the sheath and a first degree of deformability that is greater than a second degree of deformability of the sheath.
