Embodiment Construction

[0019] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses. It should be noted that the first digit of the three-digit reference number corresponds to the number of the drawing in which the element first appears.

[0020] The following description sets forth, by way of illustration only and not limitation, various embodiments of sheath tips and systems including such sheath tips to help reduce or attempt to prevent undesired effects caused by extending the sheath toward a surface and methods of using such sheath tips. As will be described in detail below, in various exemplary embodiments, the sheath tip is configured to have a shape that generally conforms to the surface of the tissue toward which the sheath tip extends, thereby possibly helping to avoid or reduce instrument penetration from the tissue wall. displacement or trauma to the tissue surface.

Abstract

The invention is entitled sheath tip with angled distal face. 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 configured to be positioned at an end of a sheath that is extendable toward a tissue at an angle to a surface of the tissue. The sheath tip has a distal end that is angled such that a periphery of the sheath tip at the distal end is configured to generally conform to the surface of the tissue.

Description

technical field [0001] The present disclosure relates to sheaths for extending elongated instruments. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] The ability to gain access to tissue within a patient's body without invasive surgery allows for ever-improving types of analysis, diagnosis, and treatment, while reducing pain, recovery time, and risk of complications. By way of two examples, endoscopic and catheterization techniques enable the evaluation and treatment of many internal lesions without invasive surgical procedures. [0004] For example, suspected or actual lesions may be sampled or treated by extending an elongate medical instrument, such as a sampling needle, through a sheath positioned by an insertion control system, such as a bronchoscope or endoscope. A sheath can extend from the insertion control system to position the elongated...
