Methods and apparatus for disinfecting and reflux prevention flush syringe assembly
Embodiments of the invention are directed to flush syringe assemblies comprising an integrated contamination-prevention device integrated with device connector flushing positioned so that the practitioner cannot forget to apply disinfectant. The flush syringe assemblies comprise a barrel with an elongate plunger rod disposed therein and a cap comprising a passageway. The plunger rod includes a stopper of which at least a portion can be embedded in the passageway of the cap to form a plug in the cap. Methods of flushing a vascular access device (VAD) while providing a flush syringe assembly described herein are also disclosed.

VASCULAR ACCESS CHANNEL AND METHODS
An embodiment includes a vascular port comprising: first and second portions that are not monolithic with each other; wherein: (a)(i) the first portion includes a first arcuate surface to contour to a first portion of a vessel and the second portion includes a second arcuate surface to contour to a second portion of the vessel; (a)(ii) the first and second portions couple to one another around the vessel when implanted to form a central chamber that houses the vessel; (a)(iii) the first portion includes a port that includes a funnel with a funnel surface that narrows as the funnel surface approaches the central chamber; (a)(iv) the central chamber includes a central longitudinal axis and the funnel includes a central vertical axis that is orthogonal to the longitudinal axis; (a)(v) the second portion includes a hardened, non-compliant surface that intersects the vertical axis.
Therapeutic delivery device
A therapeutic delivery device that provides a controlled release of high doses of a therapeutic agent in a local area, sustains the high dose controlled release with a percutaneous port for refilling the device, and is versatile for use with multiple types of therapeutic agents and/or implant systems. A rate determining/controlled release membrane is used to decrease the molecular mobility of the therapeutic compounds thereby controlling the therapeutic release profile. The therapeutic delivery device includes a body defining an internal reservoir for receiving a therapeutic agent and including a first membrane for providing a controlled release of the therapeutic agent to the surgical site, a port in fluid communication with the reservoir, a sleeve configured to encapsulate the body, and a rigid housing configured to support the body and a portion of the sleeve, the rigid housing configured to release the body and the sleeve after the body and the sleeve are anchored position relative to the surgical site.
Methods and Systems for Creating a Fluid and Pressure Equilibrium Between the Sub-Arachnoid Space and the Intraocular Compartment
A method for controlling intraocular pressure in a patient’s eye is provided. The method includes creating an intraocular entry into the eye, selecting a location along an optical disc of the eye, creating a conduit connecting at least a portion of an intravitreal cavity with at least a portion of a subarachnoid space in the eye at the selected location, deploying at least one stent communicating between the intravitreal cavity and the subarachnoid space via the conduit, and equilibrating the intraocular pressure in the eye by allowing the stent to communicate fluid flow between the intraocular compartment and the subarachnoid space.
Ultrasonic flow sensor system including a flow tube with an absorber sheath encirling the flow tube
A flow sensor sub-assembly for sensing flow of a fluidic medicament includes a flow tube having a flow tube inlet and a flow tube outlet, and an acoustical transmission rate. The medicament flows through the flow tube. A first piezo element is arranged at an upstream position of the flow tube and a second piezo element is arranged at a downstream position of the flow tube, such that the first piezo element and the second piezo element are mounted apart a pre-selected distance from each other. An absorber sheath encircles the flow tube. The absorber sheath has an upstream end and a downstream end. The absorber sheath is comprised of a material with an acoustical transmission rate different than the flow tube.
Delivery Adapter
A delivery adapter which may be used as an interface between a syringe and a catheter hub is described.
Injection needle assembly
The present disclosure relates to an injection needle assembly for use in a medicament delivery device. The injection needle assembly comprises an injection needle holder, an injection needle fixed to said injection needle holder, the injection needle having a proximal end and a distal end, and a sealing assembly for sealing the distal end of the injection needle. The sealing assembly comprises a spacer element surrounding the distal end of the injection needle and a sealing membrane for sealing the distal end of the injection needle.
Variable volume infusion port
A variable volume infusion port is provided. The infusion port may include a port body having an internal fluid reservoir, a septum, a stem to fluidly couple to a catheter lumen, and a displaceable member disposed in the internal fluid reservoir. In a first position, the displaceable member is disposed proximate the septum, providing a relatively small fluid volume within the infusion port. Insertion of an injection device through the septum causes the displaceable member to move to a second location distal from the septum, providing a relatively large fluid volume within the infusion port for the duration the injection device remains in the infusion port. The displaceable member may include a rigid member operably coupled to a biasing element or a flexible member coupled to a biasing element.
Venous Access Port with Molded and/or Radiopaque Indicia
A venous access port assembly having a base, a peripheral surface, and a septum. The base defines an interior reservoir. The peripheral surface includes integrally molded X-ray discernable indicia identifying that the assembly is rated for power injection. The X-ray discernable indicia may extend through a height of the peripheral surface from a top surface to a bottom surface thereof. According to one aspect, the peripheral surface may be formed from X-ray discernable material, and the X-ray discernable indicia may be formed from the X-ray discernable material, or they may be formed by voids in the X-ray discernable material. According to another aspect, the peripheral surface may be formed from a radiotransparent or radiolucent material and applied with a radiopaque agent, and the X-ray discernable indicia may be one or more voids in the radiopaque agent or may be portions of the peripheral surface applied with the radiopaque agent.
