A method to protect kidneys of a patient undergoing cardiac surgery patient including: administrating a diuretic to the patient to increase urine output of the patient during cardiac surgery, wherein the diuretic is administered during the cardiac surgery; anesthetizing the patient with a general anesthetic during the cardiac surgery; infusing an intravenous liquid into the patient during the cardiac surgery; monitoring a rate or amount of urine output of the patient during the cardiac surgery, and automatically adjusting a rate or amount of the intravenous liquid infused into the patient to achieve or exceed a target urine output during the cardiac surgery.

The present disclosure provides a device including comprising: (i) a concave surface at a first end of the device, (ii) a conduit at a second end of the device, and (iii) a pair of side surfaces extending inwardly at an acute angle from the first end of the device to the second end of the device.

An introducer extension with an extended, gradually curved section outside of the body enables a clinician to use an access site positioned across the body of that patient. An optional flexible or extendable section of the introducer extension allows a clinician to customize the shape of the introducer extension to a particular patient or clinician preference. The introducer extension includes a tubular sidewall extending along a longitudinal axis from a proximal end of the introducer extension to a distal end of the introducer extension and defining a lumen extending along the longitudinal axis. The tubular sidewall is configured to define a curved configuration having at least one curve between the proximal end and the distal end. The distal end is configured to couple to an introducer sheath. The lumen is configured to allow passage of a medical device.

A stabilization device is provided for attaching an instrument along a phlebostatic axis of a patient's torso, said instrument having a tether to a monitor. The stabilization device includes a flexible pad, an instrument holder, and a protection cover. The flexible pad contacts the torso along the phlebostatic axis. The instrument holder is disposed on the pad. The holder includes a clamp to secure the instrument. The protection cover connects to the holder by a hinge and rotates along the hinge between an open position and a close position. In the close position, the cover contains the clamp and the instrument. A swivel joint connects the holder to the pad for angular independence.

Various implementations include peripherally inserted central catheters (PICCs) and methods for using PICCs. In a particular implementation, a PICC includes: a lumen having an innermost layer, at least one middle layer, an outermost layer, and a proximal end for inserting into a vessel, where the lumen is puncture resistant; a luer locking mechanism coupled to a distal end of the lumen, the luer locking mechanism having at least one injection port for mating with an external injectable medical device; and a housing unit at least partially surrounding the luer locking mechanism and preventing access to the at least one injection port.

Adapters for a connector assembly for percutaneous tubing are provided. A male adapter (FIG. 22a, 1000) includes a connector fitting (1002) proximate a first end, the connector fitting configured to join to a connector for a tubing system or device, and a male connector (656) proximate a second end. The male connector includes a plug end with a fluid lumen defined therethrough, the plug end having a circumferential groove defined therein to receive a locking extension of a female connector sized to be received within the circumferential groove of the plug end to allow the female connector to rotate relative to and maintain axial engagement with the male connector when the locking extension is received within the groove. An adapter having a female connector (FIG. 24, 1300) is also provided.

An apparatus includes a pad assembly, an injector assembly, an injector driver, and a fluid source. The pad assembly is sized and configured to be placed on a forehead of a patient. The injector assembly includes a body, a flexible cannula, and a needle. The body is configured to be removably secured to the pad assembly. The cannula is sized to be inserted through an incision in an eye of a patient. The needle is slidably disposed in the cannula. The injector driver is operable to drive the needle longitudinally relative to the flexible cannula. The fluid source assembly is in fluid communication with the needle.

An embodiment in accordance with the present invention is directed to a device for fixation, stabilization, and securement of an intravascular cannula to tissue. The fixation device affixes relative to the cannula and cannulated tissue, allowing the needle to be inserted to a shallow depth and then rapidly secured with one motion, using just one hand. The device works to secure cannulae not only in small vessels but also in situations non-permissive to current state-of-the-art cannulassuch as on wet, adhesive-incompatible surfaces, in intra-operative applications, or when hands-free securement is required. The device can also be utilized to access the umbilical arteries and vein for purposes of placental perfusion for cord blood collection or to facilitate and extend the duration of conventional cord blood collection.
