  • Patent number: 10426931
    Abstract: An insertion tool for inserting a catheter into a body of a patient is disclosed. The insertion tool unifies needle insertion, guidewire advancement, and catheter insertion in a single device. In one embodiment, the insertion tool comprises a housing in which at least a portion of the catheter is initially disposed, a hollow needle distally extending from the housing with at least a portion of the catheter pre-disposed over the needle, and a guidewire pre-disposed within the needle. A guidewire advancement assembly is also included for selectively advancing the guidewire distally past a distal end of the needle in preparation for distal advancement of the catheter. In one embodiment a catheter advancement assembly is also included for selectively advancing the catheter into the patient. Each advancement assembly can include a slide or other actuator that enables a user to selectively advance the desired component.

  • Publication number: 20190275303
    Abstract: Embodiments of the present invention are directed to guidewire advancement and blood flashback systems. In particular, the insertion tool includes a frangible guidewire lever configured to break and prevent further movement of the guidewire if the guidewire becomes caught. Such a feature can prevent breakage of a distal portion of the guidewire which otherwise could undesirably lead to an embolism. The insertion tool can further include a blood flash indicator that has a simplified coupling with the needle. The insertion tool can further include a guidewire advancement assembly configured to allow the clinician to hold the insertion tool proximate a distal end and operate the guidewire advancement with one hand while providing increased control over the insertion tool. The insertion tool can further include a safety clip coupled with the catheter hub and configured to close about the needle tip when the catheter is detached from the device.

  • Patent number: 10384039
    Abstract: An insertion tool for inserting a catheter into a patient's body is disclosed. In one embodiment, the insertion tool comprises a housing in which at least a portion of the catheter is initially disposed, a hollow needle distally extending from the housing with the catheter pre-disposed over the needle, and a guidewire pre-disposed within the needle. A guidewire advancement assembly with a first finger pad is included for selectively advancing the guidewire distally past a distal end of the needle in preparation for distal advancement of the catheter. A catheter advancement assembly with a second finger pad is also included for selectively advancing the catheter into the patient. The finger pads are positioned such that a user can begin to advance the second finger pad after advancing the first finger pad without substantially re-positioning the thumb or finger of the user so as to successively advance the guidewire and catheter.

  • Publication number: 20190238800
    Abstract: Security guards at large facilities, such as airports, monitor multiple screens that display images from individual surveillance cameras dispersed throughout the facility. If a guard zooms with a particular camera, he may lose image resolution, along with perspective on the surrounding area. Embodiments of the inventive Imaging System for Immersive Surveillance (ISIS) solve these problems by combining multiple cameras in one device. When properly mounted, example ISIS systems offer up to 360-degree, 240-megapixel views on a single screen. (Other fields of view and resolutions are also possible.) Image-stitching software merges multiple video feeds into one scene. The system also allows operators to tag and follow targets, and can monitor restricted areas and sound an alert when intruders breach them.

  • Publication number: 20190217056
    Abstract: A catheter for insertion into a body of a patient, and methods of making and using. The catheter can include a distal portion that remains stable during fluid infusion into the patient, thus reducing or eliminating whipping of the catheter distal tip. The catheter includes at least one lumen and can be configured such that the arithmetic product of an elastic modulus and an area moment of inertia for the distal portion of the catheter is greater than the arithmetic product of an elastic modulus and an area moment of inertia for a proximal portion. The catheter can be attached to an implantable access port that may include features for use as a power injectable access port.

  • Publication number: 20190110645
    Abstract: A bath tub 100 for neonatal bathing including a backrest 112 that provides support for the baby at an inclined position, and a seat 152 to cooperate with the backrest 112 to flex the baby's hips to suppress the baby's urge to sit up or squirm. Embodiments may include side supports 136, 138 and/or stabilizer ribs 166, 168 to resist baby rotation about the seat 152. The tub 100 may be structured to reduce leverage to the baby to resist baby's turning over during a bath. A drain path 180 is desirably provided to maintain thermal equilibrium in the water during a bath. A system 240 may include a plurality of bathing accessories and a disposable sterile liner 264 to permit reuse of the tub 100, and/or an optional storage bag 268 to store the tub 100, and even a system 240, at a convenient location.

  • Patent number: 10155105
    Abstract: A clamp for selectively compressing a portion of tubing, such as an extension leg of a PICC or other catheter, is disclosed. The clamp is able to be opened or closed with a thumb and finger of a single hand of a user and is slidably attached to the tubing so as to enable its placement as desired along the tube. In one embodiment, the tubing clamp comprises a body including first and second body portions hingedly connected to one another in a clamshell configuration, a latch for releasably latching the first and second body portions together, and at least two tube compression members. The tube compression members cooperate to compress and occlude a portion of tubing passing through the tubing clamp when the first and second body portions are latched to one another.

  • Patent number: 9943678
    Abstract: A method for using a medical device in connection with a catheter for regulation or transfer of fluids to and from a patient. The method may include obtaining and using a medical device including a diaphragm having two unidirectional slit valves disposed therein that actuate in different directions, one slit valve actuating in one direction in response to infusion-induced pressure and another slit valve actuating in another direction in response to aspiration-induced pressure. The method may include infusing fluid through one of the unidirectional slit valves, through a lumen, and into a patient's body. The method may also include aspirating fluid from a patient's body through the lumen and another unidirectional slit valve.
