An innovative medical device that permits rapid, minimally invasive restoration of blood flow across a vascular blockage. A method employing said device, allowing for lysis or removal of said blockage. Said device creates a temporary bypass using longitudinal structure configured for insertion into the blood vessel and adapted to deliver a side hole to a target area. The side hole defines a distal first segment and a proximal second segment with a lumen to allow blood flow therethrough to the distal end hole. In an alternate embodiment, a slidable outer sheath can cover the side hole to permit reversal of blood flow from the distal end hole to a proximal end hole located outside a patient's body by means of an aspiration controller. Alternate embodiments include an optional anchoring balloon, a macerating stent or wires, perforations for fluid delivery, and a backflow valve.

A method of transarterial embolization agent delivery at a low pressure is provided. The method comprises advancing a delivery device with an occlusion structure in a retracted non-occlusive configuration through a supply artery to a vascular position in the supply artery that is in the vicinity of a target anatomical structure, the target structure having terminal capillary beds, expanding the occlusion structure from the retracted non-occlusive configuration to an expanded occlusive configuration, lowering a mean arterial pressure in a vascular space distal to the expanded occlusion structure, redirecting fluid flow from the collateral vessels toward the lowered pressure vascular space and into the target anatomical structure, injecting an embolization agent through the delivery device and into the lowered pressure vascular space, and delivering the embolization agent from the lowered pressure vascular space into the target anatomical structure. Other catheter assemblies and methods of use are also disclosed.

A treatment system includes a guide sheath, and a catheter provided with a pressure-controlled element. The pressure-control element preferably includes an expanded configuration adapted to extend across a small feeder vessel branching from the splenic vein. The pressure-control element is positioned with the feeder vessel, and a therapeutic agent is delivered under pressure directly into the feeder vessel, where it is forced to penetrate deep into tissue. Pressure responsive elements for monitoring intravascular pressure are also provided to time delivery of the therapeutic agent for maximum uptake by the target organ.

An adhesive deliver apparatus includes: a separable holder having a flexible press region thereon and comprising an interior receiving chamber for placing the adhesive tube; a support tube having a substantially elongated shape and comprising a proximal end and a distal end; a connector connected with the proximal end of the support tube and arranged to operably connect with a nozzle of the adhesive tube; and an inner tube positioned within the support tube and comprising an inlet end connected with the connector and an outlet end approximating to the distal end of the support tube; wherein when the press region is pressed to cause an interior surface of the press region to press the adhesive tube, the adhesive fluid will be squeezed out from the adhesive tube and transmitted through the inner tube from the inlet end to the outlet end.

An adhesive deliver apparatus includes: a holder; an adhesive tube, containing an adhesive fluid and positioned inside the holder, wherein the adhesive tube comprises a nozzle and a nozzle seal formed on the nozzle; a support tube comprising a proximal end and a distal end; a connector, arranged to operably connect with the proximal end of the support tube; and an inner tube, positioned within the support tube and comprising an inlet end connected with the connector and an outlet end approximating to the distal end of the support tube. When the connector is inserted into the holder, a portion of the connector would break through the nozzle seal. When the holder is pressed, the adhesive fluid will be squeezed out from the adhesive tube and transmitted through the inner tube from the inlet end to the outlet end.

A bi-directional cannula for perfusing blood in two directions. The cannula has a distal opening in fluid communication with a cannula first lumen. The cannula has a secondary opening proximal of the distal opening, and may include a movable tubular extension selectively extendable from the cannula via the secondary opening. The tubular extension may be in fluid connection with the cannula first lumen and/or a cannula second lumen. The tubular extension may have distal and/or side openings, with the openings providing antegrade fluid perfusion. The cannula second lumen may be separate from the first lumen, so that perfusion can be selectively provided to just the cannula distal opening, just the secondary opening/tubular extension, or simultaneously to both the distal opening and secondary opening/tubular extension.

Airway devices, systems, and methods are disclosed that can achieve ventilation of lungs through a mask that seals around the glottis and connects to a flexible airway channel, while also providing evacuation of gastric and/or pharyngeal body fluid and/or blood during upper airway surgeries or procedures.

A surgical apparatus for treating a blood clot in a vessel of a patient having an elongated member having an outer wall, a first hole at a distal portion and a second hole spaced proximally from the first hole positioned in a side wall. A first lumen is provided within the elongated member for blood flow through the second hole, through the lumen and exiting the first hole to maintain blood flow during treatment of the blood clot. An energy emitter emits energy to the blood clot or hardenings and a connector connects the energy emitter to an external energy source, wherein blood flows into the second hole positioned proximal of the blood clot and exits the first hole distal of the blood clot during activation of the energy emitter. In some instances when the apparatus is introduced from a retrograde upstream approach blood may flow through the device in the opposite direction.

The invention provides a catheter including: a first lumen adapted for draining a first fluid from a subject; a second lumen adapted for passing a second fluid through the second lumen; and a third lumen adapted for passing a third fluid through the third lumen such that the third fluid can exit the third lumen to bathe at least a part of an outside surface of the catheter. The invention further provides a kit and/or system including said catheter and method of use for said catheter.

The invention comprises an indwelling medical device which is capable of delivering a therapeutic agent evenly along the length of the indwelling portion, including the outer wall, of the device.
