    Abstract: A baby bottle, an insert for a baby bottle, a baby bottle including an insert, and a method of feeding an infant that serves to pace the infant's feeding rhythm. Generally, these devices and methods will be of use for a preterm infant who lacks coordination of the suck-swallow-breathe synchrony, but can also be used with full term infants who can benefit from rigid control of the flow of milk from a bottle, this includes, but is not limited to, infants with gastroesophageal reflux who can require pacing of feeds to allow for gastric emptying. The device generally cues the infant to swallow and breathe after each 1-4 sucks by stopping the flow of the fluid from the bottle after the infant has sucked sufficiently or a predetermined period of time has passed. Once the baby breathes or a period of time passes, the bottle resets for the next repetition. The device also serves to consistently slow the flow of milk during oral feeding.

  • Patent number: 9662060
    Abstract: A method and system of providing therapy to a patient's uterus is provided, which can include any number of features. The method can include the steps of inserting a uterine device into the uterus and performing a uterine integrity test to determine that the uterus is intact and not perforated. If it is determined that the uterus is not perforated, a patency test can be performed to determine that the uterine device is not clogged or embedded in tissue. If the uterus is intact and the device is not clogged or embedded in tissue, the uterus can be treated with the uterine device, e.g., uterine ablation. Systems for performing these methods are also disclosed.

  • Patent number: 9642962
    Abstract: A dialysis catheter includes an elongate catheter member having an outer wall member defining proximal and distal end regions, and first and second longitudinal lumens. The outer member includes first and second ports in respective fluid communication with the first and second longitudinal lumens. The first opening and the first lumen define an inflow passage. The second opening and the second longitudinal lumen define an outflow passage. A valve is disposed relative to the outer member proximal of the first port. The valve is adapted to move from a closed position to an open position in response to a predetermined vacuum pressure level realized within the first longitudinal lumen to permit flow of blood through the valve and into the first longitudinal lumen. The valve may be adapted to move to the open position in the event of a luminal occlusion.

  • Patent number: 9636478
    Abstract: A medical tube, which is inserted into a tubular organ and discharges and suctions fluid, is provided with a tube-shape main body which extends a prescribed length and with a valve which is disposed in a portion of the main body that is inserted into the tubular organ and can discharge or suction a fluid, wherein the valve includes multiple slits which are formed so as to extend axially of the body a prescribed length, reaching from the outer periphery to the inner periphery of the main body, and which are provided spaced in the circumferential direction of the main body. Each slit is formed tilted in the same direction with respect to a radially-extending line which passes through the axial center of the main body.

  • Patent number: 9468738
    Abstract: A catheter includes an elongate body having first and second chambers extending within the elongate body from a proximal end to an intermediate section, the first chamber having a first opening and the second chamber having a second opening at the intermediate section. The catheter also includes a valve structure that may have first and second barrier elements to open or close the first and second openings, respectively. The first and the second barrier elements may be coupled by a connecting structure moving within an opening in a guide structure. Alternatively, the first and the second barrier elements may be coupled in a U-shaped structure that moves over the guide structure. To permit flushing of the chambers when the first and second openings are closed, the first and second chambers may also be connected by a connecting channel defined by an opening in a wall of the elongate body.

  • Patent number: 9446435
    Abstract: A MEMS-based particle manipulation system which uses a particle manipulation stage and a plurality of laser interrogation regions. The laser interrogation regions may be used to assess the effectiveness or accuracy of the particle manipulation stage. In one exemplary embodiment, the particle manipulation stage is a microfabricated, flap-type fluid valve, which sorts a target particle from non-target particles in a fluid stream. The laser interrogation stages are disposed in the microfabricated fluid channels at the input and output of the flap-type sorting valve. The laser interrogation regions may be used to assess the effectiveness or accuracy of the sorting, and to control or adjust sort parameters during the sorting process.

  • Patent number: 9381018
    Abstract: A self-expanding stent-graft provided in a diametrically compacted state for implantation and retained preferably by a constraining sheath, useful for the temporary or permanent repair of injured, partially or entirely transected body conduits including blood vessels. It may be used under direct visualization to quickly stop or substantially reduce loss of blood from such damaged vessels and to quickly re-establish perfusion distal to the injury site. The device would typically be implanted under emergency room conditions but also be used in field situations by trained medical technicians. After an end of the device is inserted into a blood vessel through the injury access, deployment preferably initiates from the device end in a direction moving toward the middle of the length of the device by directionally releasing the constraining sheath.

  • Patent number: 9381295
    Abstract: An intravenous set with an automatic stopping mechanism in the drip chamber is provided. A top portion of the drip chamber may have a cap with a sharp tooth for puncturing a container or bottle. A lower portion of the drip chamber may be connected to a joint or stem that is connected to a flexible tube ending in a valve to be connected to a catheter. The drip chamber may contain a stopper for automatic control of fluid flow from the drip chamber. The stopper may include a lower part or diaphragm, a middle part or stem and an upper part. The stem and diaphragm may be connected by a stud, which is a part of the diaphragm. The stopper falls as the fluid flows through an exit of the drip chamber and closes the exit of the drip chamber when the fluid in the drip chamber is finished.

  • Patent number: 9314584
    Abstract: A method of determining fractional flow reserve (FFR) in a blood vessel having stenosis includes injecting fluid into the blood vessel upstream of the stenosis using a power fluid injector, measuring pressure drop across the stenosis, and calculating FFR from measured pressure drop. The injected fluid may comprise a contrast medium. Further actions may include placing a pressure sensor proximal of the stenosis, injecting fluid into the blood vessel upstream of the stenosis using the power fluid injector, and measuring pressure in the blood vessel proximal of the stenosis. The pressure sensor may then be repositioned to a position distal of the stenosis, fluid may be reinjected into the blood vessel upstream of the stenosis using the power fluid injector, and pressure may be measured in the blood vessel distal of the stenosis.
