  • Patent number: 12575720
    Abstract: Various disclosed embodiments include illustrative apparatuses and systems for performing multi-lumen catheter functions and methods for making the apparatuses. An illustrative apparatus includes a multi-lumen sheath, a cap having a proximal end attachable to a distal end of the multi-lumen sheath, and a liner. The cap includes a ramp section having a ramp and an exit port and an imaging section disposed distally from the ramp section. The ramp allows travel of a medical device from within the liner to the exit port. The distal ramp section extends distally from the flexible proximal section and is received by the ramp of the ramp section. The distal ramp section has a curved portion. The cap includes a socket for receiving a tab of the distal ramp section. The curved portion includes bending relief features.

  • Publication number: 20250331831
    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: 20250255582
    Abstract: An elongated access device used in a medical system. The elongated access device slidably received 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 remp 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.

  • Publication number: 20230330354
    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.
