Abstract: Disclosed are compositions, dispensers, and methods thereof for establishing a urine passageway through a ureter. For example, a composition can include, in some embodiments, a primary solid phase and a secondary solid phase. The primary solid phase can include a monomer, a pre-polymer, or a mixture thereof configured to commence polymerization into a polymeric form in the ureter when contacted with a fluid such as urine or saline. The secondary solid phase is dispersed in the primary solid phase. The secondary solid phase can include a leachable component. The leachable component is configured to leach from the polymeric form when contacted with a sufficient amount of a same or different fluid. The leachable component is also configured to form pores of an open-pore network throughout the polymeric form when leached from the polymeric form, thereby establishing the urine passageway through the ureter.

Abstract: Systems and methods directed to a renal sheath, one or more electrode pairs in the renal sheath, and a wiring system configured to connect the one or more electrode pairs to an electric current. The renal sheath can include a distal end portion, a proximal end portion, and a medial portion between the distal and proximal end portions. The medial portion can include the one or more electrode pairs. The one or more electrode pairs can be configured to produce heat sufficient to induce hemostasis in bleeding tissue surrounding the renal sheath. The wiring system can be configured to connect the one or more electrode pairs to the electric current to produce the heat sufficient to effect the hemostasis. In some embodiments, an electrosurgical generator can be configured to provide an alternating current to the one or more electrode pairs to produce the heat sufficient to effect the hemostasis.
