An apparatus includes an introducer coupleable to a peripheral intravenous line, with the introducer having a proximal end and a distal end, a catheter defining a lumen between a proximal end and a distal end, with the catheter movable from a first position where the distal end of the catheter is positioned within the introducer to a second position where the distal end of the catheter is positioned outside of the introducer, and an actuator coupled to the catheter and configured to move the catheter between the first position and the second position. The actuator moves relative to the introducer in a direction extending parallel to a longitudinal axis of the introducer when the catheter moves from the first position to the second position.

An apparatus is disclosed for an optimized transseptal procedure that reduces the number of devices that are used in order to minimize procedural time, complexity and cost. The apparatus comprises a hybrid dilator that comprises the combined functionality of a transseptal sheath and dilator assembly. The hybrid dilator comprises: a dilator shaft defining a lumen for receiving a crossing device therethrough, a distal tip having an outer diameter which tapers down to an outer diameter of the crossing device for providing a smooth transition and a hub coupled with a side arm coupled to the dilator shaft.

In at least some aspects, an instrument port for introducing an instrument into a surgical site comprises: a port body having: an instrument channel extending through the port body; and a plurality of fluid flush channels each separate from one another and the instrument channel, each extending along a major portion of the port body and in fluid communication with the instrument channel; and a bulb comprising a bulb channel extending through the bulb, the bulb channel aligned with the instrument channel, wherein the bulb channel and instrument channel are configured to receive the instrument.

A body cavity irrigation and drainage system including a catheter apparatus that has a proximal end, a distal end, a longitudinal axis, a first flow channel extending from the proximal end to the distal end, and a second flow channel extending from the proximal end to the distal end and being fluidly isolated from the first flow channel. The catheter apparatus may alterable between: (1) a first state in which the first and second flow channels are linear and parallel to the longitudinal axis along an entire length of the first and second flow channels; and (2) a second state in which a distal portion of the first flow channel curls away from the longitudinal axis in a first direction and a distal portion of the second flow channel curls away from the longitudinal axis in a second direction that is different from the first direction.

Disclosed is a system and method for the placement of elongate medical members within a patients body using coaptive ultrasound. In a particularly preferred embodiment, a flexible tube includes a first balloon at a distal end of the tube, and a second balloon at the distal end of the tube and positioned within the first balloon. The first and second balloons are inflatable to form one or more echogenic windows between them, which echogenic window may be detected from within a patient's body by an ultrasound probe that is external to the patient's body. Detection of such echogenic window is used to identify an acceptable location on the patient's body at which to insert a guidewire configured to receive an elongate medical member without damage to surrounding patient tissues or organs.

Ambulatory infusion pumps, cannula insertion mechanisms, and medicament sealing assemblies, including cannula seal assemblies, plus related components, as well as component combinations and related methods.

An apparatus includes a shaft, an expandable dilation member, and a bulbous tip. The shaft has a first outer cross-sectional dimension. The dilation member is positioned proximal to the distal end of the shaft. The dilation member is operable to transition between a non-expanded configuration and an expanded configuration. The dilation member is sized to pass through a passageway associated with drainage of a paranasal sinus or a Eustachian tube when the dilation member is in the non-expanded configuration. The bulbous tip is positioned at the distal end of the shaft. The bulbous tip is distal to the dilation member. The bulbous tip has a second outer cross-sectional dimension. The second outer cross-sectional dimension is larger than the first outer cross-sectional dimension. The bulbous tip is removably secured to the distal end of the shaft.

An apparatus for performing phlebotomy through a peripheral intravenous line. The apparatus includes an introducer and a catheter configured to advance the catheter through a peripheral intravenous line. A y-adapter with a port of larger diameter is configured to receive the catheter and place in fluid communication with the peripheral intravenous line. When advanced the catheter is configured to transport a bodily fluid (i.e. blood) to a volume outside of the body.

An intraosseous device comprises a stylet with a pointed end for penetrating bone and a cannula through which the stylet extends. The stylet has a bent portion which is engaged in a receiver in a handle cover. The cannula has an outwardly extending flare which is engaged in a corresponding seat in a hub. The handle and the hub have formations which interlock with one another when the tip of the stylet is aligned with the tip of the cannula. The interlock formations further assist torque transmission. The configuration ensures that the maximum manual torque can be applied to penetrate bone whilst ensuring that the stylet and cannula are aligned for maximum cutting efficiency and remain fixed to the handle and the hub respectively.

The implantable nerve blocking intervention involves performing a first subdermal incision on the ventral lateral portion of the patient's thorax. A first end of a tunneling device is inserted through the first subdermal incision. The tunneling device is traversed below the patient's dermal layer towards the mid axillary line. The tunneling device is traversed above the lower section of the rib cage towards the patient's paralumbar line. A longitudinal paramidline incision is performed about 3 inches lateral to the vertebral body and the tunneling device. A needle or trocar tip is inserted through the paramidline incision towards a primitive cluster of nerves and a catheter is placed through the needle or trocar which is removed prior to anchoring the catheter. A catheter tube is inserted through the length of the tunneling device. The catheter tube is coupled to the distal catheter. The tunneling device is retracted over the catheter tube. The catheter tube is coupled to a percutaneous access port.
