  • Patent number: 12290280
    Abstract: A device for draining cysts includes a catheter system configured to deploy an absorbent material, including but not limited to a foam, into a cyst. The absorbent material advantageously absorbs fluid contained within the cyst, for example fluid that may remain following aspiration, reducing the potential for cyst recurrence. In various embodiments, the absorbent material may be bioabsorbable, radiolucent, echogenic, drug eluting, or a combination thereof. In some embodiments the device may further include or be coupled to a vacuum source which applies negative pressure to the cyst during foam delivery, thereby reduce the overall size and/or profile of the cyst.

  • Publication number: 20250128001
    Abstract: A medical delivery device that includes a body, a fluid source configured to store a pressurized fluid, an enclosure configured to store an agent, the enclosure is movably coupled to the body, and a first actuator configured to release the pressurized fluid from the fluid source into the body. The enclosure is configured to move relative to the body between a first position and a second position. The enclosure is fluidly decoupled from the fluid source when in the first position such that the pressurized fluid released into the body is not in fluid communication with the agent stored in the enclosure. The enclosure is fluidly coupled to the fluid source when in the second position such that the pressurized fluid released into the body is in fluid communication with the agent stored in the enclosure.

  • Patent number: 12268380
    Abstract: A tissue traction device including a scaffold structure configured to anchor the tissue traction device in place such that a tissue traction element is anchored upon deployment of the scaffold structure and without further manipulation of the tissue traction device (such as to grasp tissue or otherwise anchor the tissue traction element to tissue). The scaffold structure may be self-supporting/self-standing to be in a deployed expanded configuration to anchor the tissue traction device with respect to the tissue. The tissue traction element may be pivotably coupled to the scaffold structure, such as to a rigid element of the scaffold structure. The tissue traction element, when anchored by the scaffold, exerts a force (e.g., traction force) on a region of target tissue to which the tissue traction element is coupled, such as via a tissue engagement member.

    Abstract: A medical device that includes a handle including a plurality of actuators. The handle defines a longitudinal axis extending through a distal end of the handle. The device includes a shaft extending from the handle and an end effector at a distal end of the shaft. A first actuator of the plurality of actuators is configured to actuate the end effector in response to translation of the first actuator relative to the handle along an axis parallel to the longitudinal axis. A second actuator of the plurality of actuators is configured to deflect the end effector relative to the shaft in response to pivoting the second actuator about an axis transverse to the longitudinal axis. A third actuator of the plurality of actuators is configured to rotate the end effector relative to the shaft in response to rotation of the third actuator relative to the handle about the longitudinal axis.

  • Patent number: 11957350
    Abstract: A device includes an elongated hollow member having an open distal end for receiving tissue therein and at least one exterior groove for loading at least one ligation band thereon. The device also includes a band deployment sleeve slidable over the exterior of the hollow member and configured to move from a radially expanded position to a radially contracted position in which, when the band deployment sleeve slides longitudinally over the hollow member, the distal portion engages the at least one ligation band. A closing sleeve slidable over the exterior of the band deployment sleeve is configured to constrain the distal portion from the radially expanded position into the radially contracted position. Retracting the closing sleeve proximally over the distal portion of the band deployment sleeve releases the distal portion from the radially contracted position into the radially expanded position.
