  • Publication number: 20210379302
    Abstract: The present embodiments provide systems and methods suitable for delivering a therapeutic agent to a target site. In one example, the system comprises a container for holding the therapeutic agent, and a pressure source having pressurized fluid, wherein the pressure source is in selective fluid communication with at least a portion of the container. A catheter is placed in fluid communication with the container, and has a lumen sized for delivery of the therapeutic agent to a target site. A housing is configured to securely retain the container. The system further comprises a camera having a camera head coupled to the catheter, wherein the camera provides a visual image of the target site during delivery of the therapeutic agent.

  • Publication number: 20210346568
    Abstract: The present embodiments provide systems and medical formulations suitable for delivering therapeutic powders to a target site. In one embodiment, the system comprises a delivery device, a first powder being formed of particles of a first material, and a second powder being formed of particles of a second material, wherein the second material is different than the first material. At least some of the particles of the first powder and the second powder are bound together to form bonded particles. The bonded particles are simultaneously delivered to the target site by the delivery device. In one embodiment, a medical formulation may comprise carbomer present in a range between about 60-80% by weight of the formulation, bentonite present in a range of between about 5-15% by weight of the formulation, and calcium carbonate present in a range of between about 10-30% by weight of the formulation.

  • Publication number: 20190091374
    Abstract: A method of treating a lesion in a gastrointestinal tract and an injectate system are provided. The method includes injecting a crosslinkable gel into a first tissue layer, the crosslinkable gel increasing a volume of the first tissue layer. The method also includes providing a crosslinker and resecting a portion of a first tissue layer having the increased volume away from a second tissue layer creating an exposed region in a remaining portion of the first layer and leaving a portion of the gel covering at least a portion of the exposed region. The injectate system includes a crosslinkable gel and a crosslinker where the crosslinkable gel and the crosslinker form a crosslinked gel having a compressive modulus of about 10-500 kPa.
