A MEDICAL DEVICE
This invention relates to a medical device. The device includes an elongate cannula which is insertable into a blood vessel and which is resiliently biased towards a closed condition in which it inhibits fluid flow through the cannula. The cannula is displaceable away from its closed position by the introduction of a displacement arrangement such as a device or instrument or a pressurised fluid and reverts to its closed condition when the displacement arrangement is removed from the cannula to inhibit the flow of blood therethrough. The invention further relates to a needle for use with the medical device, to a kit and to a method of accessing a blood vessel. In addition, it relates to a method of closing an incision in a blood vessel and to a closure member for use in the method.

Aspiration catheter systems and methods of use
Described are methods, systems, devices for facilitation of intraluminal medical procedures within the neurovasculature. A catheter advancement device includes a flexible elongate body having a proximal end, a distal end, and a single lumen extending therebetween. The flexible elongate body has a proximal segment, an intermediate segment, and a tip segment. The proximal segment includes a hypotube coated with a polymer. The intermediate segment includes an unreinforced polymer having a durometer of no more than 72D. The tip segment is formed of a polymer different from the intermediate segment and has a durometer of no more than about 35D and a length of at least 5 cm. The tip segment has a tapered portion that tapers distally from a first outer diameter to a second outer diameter over a length of between 1 and 3 cm.
Medical device bending tool
A method and system of bending medical device components for customization to a particular medical procedure and patient while generally maintaining the ideal performance of the component. A medical professional embeds the medical device component into a bending tool. The medical professional then aligns an intended curve region of the medical device component within a bending region of the bending tool and imparts a curve in the bending region. Finally, the medical professional withdraws the medical device component from the bending tool, and utilizes the bent medical device component in the medical procedure. The system may be a kit comprising various medical device components for a particular medical procedure and a suitable bending tool for those components.
Integrated vascular delivery system
An integrated vascular delivery system and method of use, the system including: a frame having a catheter hub that provides a first anchoring point on the patient and receives a catheter insertable in the patient to transfer fluid at an insertion site, a stabilization hub that provides a second anchoring point on the patient, at least one lateral member extending between the catheter and stabilization hubs, and a fluidic channel. The frame operates in a folded configuration in which the hubs are coupleable and an unfolded configuration in which the anchoring points are distributed around the insertion site to anchor the frame to the patient, thereby stabilizing the catheter. In some embodiments, the system further includes a septum that helps prevent fluid leakage from the catheter hub, or a needle shield that covers the distal end of a needle used during catheter insertion.
Integrated vascular delivery system
An integrated vascular delivery system having a frame configured to receive a catheter insertable in a patient to deliver fluid at an insertion site. The frame includes a first hub, a second hub, and a pair of flexible lateral members extending between the hubs and including a tubular lateral member. The system also includes a fluidic channel that fluidically communicates with the catheter, wherein the fluidic channel passes through the tubular lateral member and at least one of the hubs, and includes a fixed turnabout portion in which fluid flows in a direction different from that within the catheter. The first and second hubs provide anchoring points on the patient distributed around the insertion site and on opposite ends of the catheter, thereby anchoring the frame to the patient and stabilizing the catheter. A method is provided for using an integrated vascular delivery system.
Intravenous catheter insertion device and method of use
A catheter insertion device includes a housing, a needle, a guide wire, and a catheter disposed coaxially over the needle. The needle has a proximal end in the housing and a distal end extending from a distal end of the housing in an insertion position. The guide wire has a distal portion disposed in a lumen of the needle in a withdrawn position. The guide wire may include a safety tip having a non-coiled configuration in the withdrawn position and a coiled configuration in an advanced position. The catheter insertion device may include a sliding member attached to the guide wire, wherein movement of the sliding member translates the guide wire from the withdrawn position to the advanced position.
METHOD AND DEVICE FOR INTERMITTENTLY TRIGGERING A REFLEX-COORDINATED DEFECATION
The invention relates to a method for filling an inflatable catheter balloon of a device for transanally introducing an infusion into the rectum or colon of a patient by means of a filling device, wherein a fill volume or a filling pressure prevailing in the catheter balloon is increased in two or more steps until there occurs a gradual, user-controllable, pneumatically initiated expansion of portions of the bowel wall, thus triggering a coordinated defecation reflex, wherein the timing and intensity of the triggering stimulus can be determined to the greatest possible extent by the user.
SAFETY IV CATHETER WITH V-CLIP INTERLOCK AND NEEDLE TIP CAPTURE
A catheter assembly (10) comprises a catheter (22), a needle (12) having a sharp distal tip, a catheter hub (14) housing the catheter (22), the catheter hub (14) having a collar (34) including a notch (36), a needle shield (20) connected to the catheter hub (14) when the needle (12) is in a first position, and a clip (40) disposed in the needle shield (20) that cooperates with the needle (12), wherein the clip (40) engages the catheter hub (14) in the first position of the needle (12), and the clip (40) disengages the catheter hub (14) via the notch (36) when the needle (12) is retracted to a second position to cover at least a portion of the needle (12). The clip (40) is mounted in the outer housing (38) of the needle shield (20) via a spade (66) having an outer wall (70) exposed to the outside of the needle shield (20), in order to reduce the overall width of the needle shield (20).
METHODS AND DEVICES FOR DELIVERING LIQUID THERAPEUTIC AGENTS IN SOLID TUMORS
Various exemplary methods and devices (10, 110, 210) for delivering liquid therapeutic agents in solid tumors are provided. In general, a delivery device configured to deliver a liquid therapeutic agent into a solid tumor or other soft tissue can be configured to compress tissue and seal any fluid gaps around the delivery device during the delivery of the liquid therapeutic agent. In an exemplary embodiment the delivery device includes three elongate tubular shafts (12, 14, 16, 112, 114, 116, 212, 214, 216) configured to move longitudinally relative to one another. The elongate tubular shafts are configured to cooperate with one another to deliver the liquid therapeutic agent through a passageway of the delivery device to the solid tumor or other soft tissue and seal any fluid gaps around the delivery device while the liquid therapeutic agent is delivered into the solid tumor or other soft tissue.
