An exhaust collection bag for cryogenic treatment is described herein and may generally comprise a first layer and a second layer attached along a periphery and forming an enclosed volume. The periphery defines four radiused corners and an extension member. A tubing connector may be positioned along the first layer and extend through the first layer and may also be located along a centerline of the first layer and in proximity to a bottom edge of the first layer. A drain closure may also be positioned along the first layer and located away from the centerline and in proximity to the bottom edge.

Embodiments for a cerebrospinal fluid flow detector for detecting the flow of cerebrospinal fluid are disclosed. In some embodiments, the cerebrospinal fluid flow detector includes a casing with a rotatable wheel having a plurality of radially extending arms disposed therein. The rotatable wheel is in communication with a channel having a distal end in communication with an inlet port and a proximal end in communication with an outlet port such that the flow of cerebrospinal fluid through the channel causes the rotatable wheel to rotate. In some embodiments, each radially extending arm includes at least one radiopaque marker in which movement of the rotatable wheel caused by fluid flow through the channel allows an X-ray imaging apparatus to detect the difference in position of a respective radiopaque marker at multiple times caused by rotation of the rotatable wheel.

A percutaneous drainage device for draining a fluid collection located under the skin of a patient is disclosed. The percutaneous drainage device includes a penetration component slidably engaged with a cannula. The penetration component has a piercing end adapted to penetrate tissue of a patient and introduce an open end of the cannula to a subcutaneous fluid collection site. The cannula may be held in place in the patient by an anchoring means. The cannula provides a passage through which a fluid collection may be drained from a patient. The cannula may be in fluid communication with a collection vessel, which collects fluid collection transported away from the subcutaneous fluid collection site.

A chest tube device with neurostimulation is provided, along with a method of electrically stimulating at least one of (i) one or more peripheral nerves and (ii) one or more nerve fibers of a thoracic region of a patient, to mitigate pain in patients undergoing chest tube implantation. The chest tube device includes a tubular member and an electro-analgesic region to provide neurostimulation to one or more peripheral nerves and/or nerve fibers of the thoracic region of the patient. The method includes electrically stimulating one or more peripheral nerves and/or nerve fibers of the thoracic region of the patient, and hyperpolarizing the one or more peripheral nerves and/or nerve fibers of the thoracic region to (i) reduce an amount of pain signals from being transmitted to the brain of the patient and/or (ii) prevent pain signals from being transmitted to the brain of the patient.

Described herein is the use of CSF, more particularly external CSF or CSF-like compositions for the treatment and prevention of different diseases. More particularly, the application provides for the administration of CSF to the intrathecal space or the cerebral ventricles of a patient to increase intracranial pressure and/or CSF flow.

Glaucoma treatment systems are disclosed. In various example, the glaucoma treatment systems include a body and a fluid conduit configured to facilitate an evacuation of fluid, such as aqueous humor, from a fluid-filled body cavity, such as an anterior chamber of an eye. In some examples, the fluid conduit is soft and compliant, and the glaucoma treatment system includes one or more stiffening members coupled with the fluid conduit to temporarily stiffen the fluid conduit and help aid in the delivery of the glaucoma treatment device. In some examples, the stiffening members are removable from the fluid conduit after the glaucoma treatment system has been implanted.

Systems and methods provide for holding surgical drain evacuators in inelastic expandable pouches. Particularly, apparatuses and methods include or utilize garments for supporting and protecting surgical drain evacuators and surgical drains include straps or belts for attaching the garment to a patient. The garments include one or more expandable pouches configured to receive a surgical drain evacuator, wherein the expandable pouch is formed of a flexible inelastic material.
