An automatic vessel access device based on real time volumetric ultrasound is provided. The automatic vessel access device comprises a probe configured to generate a VOI image of a candidate vessel in a real time volume ultrasound scan mode, a control device coupled to the probe, and at least one motor coupled to the control device. The control device comprises at least one processing module configured to determine at least one control parameter based on the VOI image, and a driver module coupled with the at least one processing module and configured to drive the at least one motor to automatically access the candidate vessel according to the at least one control parameter.

A catheter or guide wire manipulating device for vascular intervention is provided, comprising a thumb component (3), a forefinger component (4), a driving component (1) and a catheter/guide wire support component (2); the thumb component comprises a roller (7) configured to advance or retreat the catheter/guide wire; the thumb component (3) is configured to drive the catheter/guide wire to rotate clockwise or counterclockwise through a combination motion of the components; the forefinger component (4) is configured to cooperate with the thumb component (3) to implement the rotation and the advancement of the catheter/guide wire by moving manually away from the thumb component, and returning by a pull force of a spring (23) after being released; the driving component (1) is configured to drive the thumb component (3) and the forefinger component (4); the catheter/guide wire support component (2) comprises a Y adapter fixation configured to install a Y adapter and an entry support configured to support and guide the catheter/guide wire into a mechanism.

A vascular access device may include a housing. An inner surface of the housing may include a groove disposed within the housing between the proximal end and the distal end. An advancement element may extend through the slot and may be configured to move linearly along the slot between a retracted position and an advanced position. An instrument, having a first end and a second end, may be disposed within the groove. In response to movement of the advancement element from the retracted position to the advanced position, the second end of the instrument may be advanced beyond the distal end. A support feature may be disposed on top of the groove or within the groove and configured to move distally in response to movement of the advancement element from the retracted position to the advanced position. The support feature may limit displacement of the instrument from the groove.

Disclosed are two-piece rapidly insertable central catheter (“RICCs”), introducers, and methods. For example, an introducer and a distal catheter piece of a RICC can be combined in an introducer assembly configured to be actuated with a single finger of a hand while the introducer is held between a thumb and another finger or fingers of the same hand. A catheter-advancement hub of the introducer includes a manifold coupled to a proximal portion of a distal catheter-hub piece of the distal catheter piece. An introducer needle of a syringe of the introducer has a needle shaft extending through the manifold and a distal end of the distal catheter piece. An introducer housing is over a syringe tip, the manifold, and the proximal portion of the distal catheter piece. The introducer housing of the introducer configured to provide column strength to a catheter tube of the distal catheter piece during a venipuncture.

The embodiments presented herein relate to concepts designed to eliminate the gap between a catheter and guide wire that can otherwise contribute to a catheter getting stuck within the vasculature.

The catheter introducer assembly comprises an outer tube, an outer tube housing, a needle, a needle extension member, a spring, and a retainer portion. The outer tube nests within the outer tube housing. The needle, needle extension member, and the, spring nest within the outer tube and outer tube housing. The needle tip is moved from the first position to a second position upon connection of a male luer slip to the retainer portion and the needle tip is moved from the second position to the first upon decoupling.

Provided is a treatment method and medical apparatus for preventing an object that becomes a causative agent causing pathogenesis of aspiration pneumonitis from invading a lung The treatment method includes a disposing step of disposing a first instrument, which allows the object that becomes a causative agent of aspiration pneumonitis to move from an esophagus to a stomach and suppresses movement of the object from the stomach to a larynx, in the esophagus and disposing a second instrument, which suppresses the object from invading the lung, in at least the larynx.

A steerable guidewire. The steerable guidewire is fabricated includes an outer tube, an inner tube, a hub, and a distal articulating region. The steerable guidewire hub can be removed to permit advancement of catheters over its proximal end followed by re-attachment of the hub to permit deflection of the distal end of the steerable guidewire.

The present teachings generally relate to translation catheter systems and method of using thereof in treating defective mitral valves. Specifically, a translation catheter system includes a catheter configured to move substantially laterally along the mitral annulus and the lateral movement of the catheter is substantially continuous and substantially adjustable. Accordingly, a method of using such a translation catheter includes advancing a first wire across the mitral annulus at a first treatment location, delivering a catheter at or near the first treatment location, moving the catheter substantially laterally to a second treatment location, and advancing a second wire across the mitral annulus, where the distance between the first and second treatment locations is substantially adjustable and optionally visualized.

In one representative embodiment, a gripping and pushing device for a medical instrument comprises an elongated main body defining a lumen. The elongated main body comprises one or more deflectable portions that can be pressed radially inwardly toward a shaft of the medical instrument extending through the lumen. One or more elastomeric gripping layers can be secured to the inner surface of a respective deflectable portion at axially spaced apart attachment locations. The one or more gripping layers are axially deformable relative to the one or more deflectable portions between the attachment locations when manual pressure is applied to the one or more deflectable portions to press the one or more gripping layers against the shaft and move the shaft longitudinally into a patient's body.
