Devices, methods, and systems for controlling a bladder of a subject are disclosed. For example, an apparatus for controlling the bladder can comprise a garment or accessory configured to be worn at least partially around a lower truncal region of a subject and a compression device coupled to the garment or accessory. The compression device can be configured to pressurize an abdominal wall of the subject when the garment or accessory is worn by the subject. The compression device can comprise a device housing having a contact surface, a device base, and an actuator. The actuator can translate the device housing in relation to the device base in a medial or lateral direction relative to the subject such that the contact surface of the device housing applies compressive forces to the abdominal wall of the subject when translated.

The apparatus and method for hemostasis that informs the provider as to whether the appropriate magnitude of pressure is being applied to a puncture site on a patient. A visual pulse indicator can visually convey whether or not there is proper blood flow at the puncture site based on the pulsing motion encountered by the visual pulse indicator on the puncture site. The visual pulse indicator can potentially factor in a variety of different input parameters in displaying information that is useful to providers.

Systems and methods and devices are provided for treating conditions such as heart failure and/or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The occlusion device may include a lumen obstructed by a relief valve that may permit fluid flow through the occlusion device to release an excessive build-up of pressure.

There is provided a method for controlling the movement of bile and/or gall stones in the biliary duct. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the tissue wall) at least one portion of the tissue wall to influence the movement of bile and/or gallstones in the biliary duct, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the movement of bile and/or gallstones in the biliary duct. The method can be used for restricting or stopping the movement of bile and/or gallstones in the biliary duct, or for actively moving the fluid in the biliary duct, with a low risk of injuring the biliary duct.

A phlebotomy cuff assembly for enhancing visibility of veins for phlebotomy includes a cuff that can be wrapped around a patient's limb and a bladder is integrated into the cuff. A first mating member is coupled to the cuff, a second mating member is coupled to the cuff, and the second mating member is matable to the first mating member for forming the cuff into a closed loop around the patient's limb. A hose is fluidly coupled to the bladder and a bulb is fluidly coupled to the hose such that the bulb can be compressed by a caregiver for inflating the bladder. In this way the bladder can compress against the patient's limb to make veins in the patient's limb more visible.

A hemostasis pressure device is disclosed. In one embodiment, the hemostasis pressure device includes a reusable component and a disposable cuff. The disposable cuff includes a pre-inflated pad configured to be placed at an access site on a patient. A knob secured to the reusable component is configured to control the pressure applied to the pre-inflated pad, providing incremental, fine-tuned control of pressure applied to the access site to achieve patent hemostasis.

Systems and methods for removing material from a blood vessel or cavity inside a body by suction, wherein the magnitude of suction is increased by applying extracorporeal positive pressure. Positive pressure outside the body is increased such that the potential negative pressure inside the body may be increased. Methods include inserting a catheter into a blood vessel or cavity and positioning a distal opening of the catheter proximate the material to be removed. Extracorporeal positive pressure is applied to at least a portion of the body containing the material to be removed, and suction is simultaneously applied to the catheter to more effectively remove the material.

The bypass syringe is used in combination with an expandable or inflatable bladder or balloon that is circumferentially wrapped around a patient designed to reduce bleeding from a skin insertion wound site and a vascular wound site after a vascular intervention or surgical procedure is performed. The bypass syringe is designed to pre-inflate the balloon, allow the balloon to relax based on how tightly the band is wrapped around the patient, and then be inflated with a volumetric amount of fluid. The bypass syringe's pre-inflation step will reduce complications caused by variabilities in band securement or tightness. A pre-inflation step combined with a venting of excess air step or controlled pressure inflation steps will absorb/take up/consume excess space caused by variability in band securement and help to reduce complication caused by securement variability.
