Abstract: In various embodiments, the present disclosure provides an injection system for injecting a fluidic treatment substance into an orifice of an animal. In various implementations the system comprises a treatment cartridge having a hollow body that is structured and operable to retain a treatment substance within the hollow body. The system further comprises a plunger assembly structured and operable to removably retain the treatment cartridge and controllably dispense the treatment substance from the treatment cartridge. In various implementations the injection system can additionally include an injection site cleaning adaptor that is removably connectable to the treatment cartridge and is structured and operable to clean a site in which the treatment substance is to be injected.

Abstract: An endoscopic device providing direct visualization of a surgical procedure, such as a surgical procedure in which there is significant body and/or artificially introduced fluids is provided. This endoscopic device comprises catheter with a lumen in which a transparent gel may be housed. During the surgical operation the transparent gel may be dispensed at the target site to displace the body fluids, such as blood. A visualization tool housed in the catheter may then be inserted into the gel to allow a surgeon to view the target site through the gel. Additionally, the catheter may comprise a surgical tool(s) that a surgeon may use to perform an operation at the target site. After completion of the operation, the gel and tools may be retracted back into the catheter and removed from the patient's body.
