Sheath with detectable leader

Abstract

The invention is entitled sheath with detectable leader. Disclosed embodiments include apparatuses, systems, and methods for providing a sheath tip with an angled distal face to conform the sheath toa 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. Inan 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.

Description

technical field [0001] The present disclosure relates to sheaths for extending elongate 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 tissues within a patient's body without invasive surgery allows for continuous improvements in analysis, diagnosis and type of 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 e...

Problems solved by technology

For example, because the insertion control system can operate in tight spaces, in minimizing or attempting to avoid or minimize trauma to tissue at or near the desired location, or caused by contact between the insertion control system and the tissue wall Sampling or treating at desired locations within the body can be challenging, along with other undesired effects of

Although an insertion control system may include one or more sensing devices to detect the tissue of interest and / or the position of the elongated medical device used in the monitoring procedure, it may still Verifying the position of slender instruments with other undesired effects presents challenges
