    摘要： A vascular closure device includes a release component, a delivery component, a sealing device and at least one actuator. The release component is elongate along a longitudinal direction, and defines a distal end and a proximal end. The delivery component extends along the release component such that at least the release component is movable relative to the delivery component. The delivery component includes a delivery tube body and defines a delivery tube channel. The sealing device has a toggle that is at least partially disposed within the release tube, a suture that is attached to the toggle and extends through the delivery tube channel, and a plug that is attached to the suture proximal to the toggle. The actuator is coupled to the release component and is in communication with the suture such that actuation of the actuator causes (i) the release component to move the proximal direction relative to the delivery component so as to release the toggle from the release component, and (ii) the suture to be pulled in a proximal direction to thereby place the filament in tension and urge the toggle against a distal end of the delivery component such that the toggle is oriented in a sealing position.

    摘要： Split support catheters, loading tools, and methods of use are disclosed. A support catheter can include an elongate tubular member and a push member. The tubular member can comprise a longitudinal slit configured to accommodate the exchange of various interventional devices into and out of the lumen defined by the tubular member. A loading tool can comprise a body member, a rod member, or both and can facilitate loading of the support catheter onto one or more interventional devices during a medical procedure. The support catheters can provide intravascular support to various interventional devices and can advantageously be inserted and removed without first removing an interventional device having its distal end at or near a target site within a patient's vasculature.

    摘要： A captivation catheter for use with a guide catheter and a guidewire or a treatment catheter. The captivation catheter includes a relatively rigid elongate member and a captivation mechanism such as an inflatable balloon capable of fixing the guidewire or the treatment catheter in place against an inner surface of the guide catheter. The captivation catheter can include a clip with an open end and a closed end that is placed on the captivation catheter at markings present for compatibility with a particular working length of the guide catheter. The markings can be visible at different viewing orientations.

    摘要： Methods, devices and systems for location of the disposition of a medical probe in a subject are disclosed. An array of electromagnetic drive coil sets, each set having two or three dimensionally oriented drive coils, a sensor coil being electromagnetically communicative with the array of electromagnetic drive coil sets, a discrete core wire providing response to electrical stimuli of the subject, and a system controller communicative with and adapted to energize one or more of the electromagnetic coils in the array of electromagnetic drive coil sets are disclosed. The energizing of the one or more of the electromagnetic coils including one or more of energizing the coils singly, or in pairs of x-y and y-z or x-z coils while measuring the response of the sensor coil, whereby the system uses the measurements of the responses of the sensor coil to calculate the location of the sensor coil relative to said drive coil sets.

    摘要： Assistive apparatuses or devices, kits, and methods for assisting with removal of a biological sample from an intraosseous device are described. Some of the present assistive apparatuses comprise: a body including a first end and a second end, and defining a channel with a first portion having a first transverse dimension, a second portion disposed between the first portion and the second end and having a second transverse dimension that is smaller than the first transvers dimension, and a longitudinal axis extending through the first portion and the second portion, the body further including a protrusion extending laterally outward relative to the longitudinal axis; where the channel is configured to receive a portion of an intraosseous device having a hub and a cannula extending from the hub, with the first portion of the channel receiving a part of the hub, and the second portion of the channel receiving a part of the cannula while preventing passage of the hub through the second portion.
