  • Patent number: 11883003
    Abstract: 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.

  • Patent number: 11672922
    Abstract: Disclosed embodiments include apparatuses and methods for using a tip member to deposit or collect a supply of material from within a body. In an illustrative embodiment, an apparatus includes a tip body defining an annular chamber. A tip receptacle is configured to be joinable with a lumen and to receive a fluid flow therethrough and to convey the fluid flow into the annular chamber. A material distribution element is fluidly coupled with the annular chamber, wherein when the fluid flow is introduced into the annular chamber. The material distribution element diffusively passes the fluid flow out of multiple egress points in at least one of a distal end and a lateral surface of the tip body.

  • Patent number: 11564655
    Abstract: An elongated access device used in a medical system. The elongated access device slidably receives a medical tool and an ultrasound probe. The elongated access device includes a sheath and an intraluminal tip attached to the distal end of the sheath. The intraluminal tip includes ramp and nose donuts being spaced apart from one another and configured to be attached to one or more elongated sleeves. One or more orientation pins are engaged with the respective ramp and nose donuts and may be anchored within the sheath. The medical tool is engaged with a ramp formed in the ramp donut or a ramp received within the ramp donut. The ultrasound probe is configured to engage with the intraluminal tip so as to ensure that the medical tool directionality is oriented toward a target during a procedure.

  • Patent number: 11166625
    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.

  • Publication number: 20210059648
    Abstract: A device and system for allowing real-time viewing of a procedure beyond a distal end of an endoscope. An exemplary device includes a sheath that has at least two lumens and a handle. The handle includes a connector that connects to a proximal end of an endoscope, a shaft portion that rotatably connects to a proximal end of the connector and a manifold that is slidably received by the shaft portion. The manifold connects to the sheath and allows for insertion of a radial ultrasound probe and a medical tool into the sheath. A stopping device in the manifold avoids accidental needle deployment.

  • Publication number: 20200288952
    Abstract: An apparatus for controlling advancement of a sheath or a catheter at a distal end of an endoscope. An exemplary apparatus includes a flexible sheath that receives a medical device within an internal lumen and is received within a working channel of an endoscope. The apparatus also includes a component that is at least one of external or internal to the sheath. The component causes a change in longitudinal motion friction of the sheath above a predefined threshold amount as the sheath moves relative to an exit ramp of the endoscope.
