Disclosed embodiments include apparatuses, systems, and methods for providing a sheath tip with a solid end surface configured to be pierceable by an instrument, where the solid end surface is configured to distribute force of impact with a tissue surface across the solid end surface. In an illustrative embodiment, an apparatus includes a closed sheath tip has a solid end surface configured to be pierceable by an instrument. The closed sheath tip is configured to be disposed at a distal end of a sheath defining therein a lumen configured to convey the instrument therethrough. When the closed sheath tip is presented at a tissue surface, the solid end surface of the closed sheath tip is configured to distribute force of impact with the tissue surface across the solid end surface and to permit the instrument to pierce the solid end surface and extend therethrough toward the tissue surface.

Penetrable closed sheath tip

Disclosed embodiments include apparatuses, systems, and methods for positioning electrodes. In an illustrative embodiment, an apparatus includes a primary electrode defining a lumen, an elongated secondary electrode slidably receivable within the lumen, and a sheath configured to slidably receive the electrodes and to convey the electrodes toward a target region. A housing is coupled with the sheath and movably mounted to motivate the sheath relative to the target region. A primary actuator is coupled with the primary electrode and slidably coupled with the housing to motivate the primary electrode relative to the sheath. A secondary actuator is coupled with the secondary electrode and movably coupled with the primary actuator to be slidable with the electrodes in concert. The secondary actuator is rotatable independently of the primary actuator to travel along a helical path to motivate the secondary electrode to move relative to the target region independently of the primary electrode.

User interface and lock features for positioning multiple components within a body

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.
