  • Patent number: 10478109
    Abstract: A fluid transfer device for parenterally transferring fluid to and/or from a patient includes a housing, a needle, and an occlusion mechanism. The housing defines a fluid flow path and is couplable to a fluid reservoir. The needle has a distal end portion that is configured to be inserted into the patient and a proximal end portion that is configured to be fluidically coupled to the fluid flow path of the housing, and defines a lumen therebetween. The occlusion mechanism selectively controls a fluid flow between the needle and the fluid flow path. The occlusion mechanism includes an occlusion member that is movable between a first configuration where the lumen of the needle is obstructed during insertion into the patient and a second configuration where the lumen of the needle is unobstructed after the needle has been inserted into the patient allowing fluid transfer to or from the patient.

  • Patent number: 9833593
    Abstract: The present invention relates to a catheter for treating ectopic pregnancy, of which one end is inserted into the fallopian tube through the vaginal cavity, and the other end is exposed to the outside of the body, wherein the catheter comprises: at least one passage portion forming a liquid passage entering through the one end or the other end; a penetrative portion connected to the one end, and including a foremost end for penetrating the gestational sac; and a connecting portion connected to the other end, and capable of being coupled to at least one syringe tool for injecting or suctioning the liquid. Accordingly, side effects from open surgery can be prevented, and excellent treatment effects can be obtained by more safely and quickly treating ectopic pregnancy.

  • Patent number: 9814591
    Abstract: A spacer member is provided that is configured to be implanted adjacent an anatomical structure. The spacer member defines a curved bore, a first opening in a side wall of the spacer member and a second opening in one of a top wall and a bottom wall of the spacer member. Each of the first opening and the second opening are in fluid communication with the curved bore. A flexible anchoring member is configured to be inserted through the side opening and through the curved bore of the spacer member such that a distal end portion of the flexible anchoring member extends out of the second opening at an angle relative to the one of the top wall and the bottom wall of the spacer member.

  • Patent number: 9795766
    Abstract: A catheter assembly includes a catheter adapter and an introducer needle. The introducer needle extends through the catheter adapter and through a catheter tube so as to assist placement of the catheter tube into a patient's blood vessel. Blood flashback into the catheter tube and/or catheter adapter through an aperture in a side of the needle indicates when the catheter tube is within the blood vessel. After the catheter tube is placed in the blood vessel, the introducer needle is withdrawn. A primary septum within the catheter adapter blocks blood flow in a proximal direction past the primary septum. A secondary septum proximal the primary septum is biased so as to enter into the aperture in the introducer needle and plug the aperture while the needle is being withdrawn, thus blocking blood flow through the aperture after the aperture is drawn through the primary septum.

  • Patent number: 9682222
    Abstract: A microneedle injection apparatus (100) comprising an inverted actuator. The apparatus can include a housing (102) having a base and a cavity, and a microneedle array holder (106) configured to hold a microneedle array (107) within the cavity of the housing. The microneedle array holder can be movable between a retracted position, and an extended position. The apparatus can further include an actuator (104) movable with respect to the housing and the microneedle array holder between a first position and a second position to cause the microneedle array holder to move from the retracted position to the extended position. At least a portion of the actuator can be located on a skin-facing side of the apparatus (e.g., adjacent the base of the housing) and can be configured to be moved from the first position to the second position in response to the apparatus being pressed toward the skin surface.

  • Patent number: 9669198
    Abstract: A system and related method for delivering the anti-tumoral agent carmustine or other types of diagnostic or therapeutic agents into the brain of a patient with a brain tumor includes an insertion device, a skull mount, and a reformulated geometry of the carmustine compound (or other material) optimized for use in the insertion device and for maximized biodegradation time. The insertion device may be front loaded with the carmustine material (or other material) and inserted through the mount on a skull, to the location of the brain tumor, where the carmustine (or other material) is then released. It should be appreciated that the diagnostic and/or therapeutic system and related method thereof are not necessarily limited to the brain of a subject. It may also be used in the organ structures or tubular structures, as well as portions and locations thereof.

  • Patent number: 9623210
    Abstract: Catheter assemblies are described having a catheter hub with a catheter tube and a needle hub with a needle projecting through the catheter tube. The catheter hub has a valve or a septum for stopping or slowing down the flow of fluid in or out of the catheter hub when the valve or septum is closed. The valve or septum has an exposed proximal wall that enables the valve to be wiped or cleaned with an antiseptic solution. The valve further has a cavity for receiving at least part of a needle guard, which is incorporated for preventing accidental needle stick with the needle tip.

  • Patent number: 9616203
    Abstract: A method and device are provided for simultaneously or near-simultaneously diagnosing and treating tension pneumothorax and/or hemothoraxA Veress-type needle portion includes a hollow needle for puncturing the chest wall over a blunt hollow probe biased by one or more springs to extend distally into the pleural cavity. Openings in the blunt hollow probe connect via a pathway to an automatic check valve, which permits the flow of air and/or fluid only in a proximal direction. Pressure from within the pleural cavity is transmitted to the interior surface of a pressure documenter. If pressure greater than atmospheric pressure is present in the pleural cavity, the pressure documenter will be automatically urged proximally to simultaneously allow air and/or fluid to escape from the pleural space through the device, thus treating the tension pneumothorax and/or hemothorax, as well as providing a stable indicator to positively document the diagnosis of increased pressure.

  • Patent number: 9604740
    Abstract: An injection member penetrates an elastic septum of a device defining a sealed, empty, sterile chamber in fluid communication with the septum. During penetrating, an annular interface is formed between the septum and the injection member extending axially between a penetration point on an interior surface of the septum in fluid communication with the sterile chamber, and an exterior surface of the septum engaging the injection member. The injection member is de-contaminated by (i) friction between the septum and injection member at the annular interface, and (ii) elongation of the septum at the annular interface. A substance is introduced through the injection member and into the sterile chamber of the device, the injection member is then withdrawn from the septum, the septum reseals itself at the resulting penetration aperture, and the chamber is maintained sterile throughout the foregoing steps.
