Balloon catheter flow device
Disclosed is an inter- and intra-catheter flow device for the management of vascular bleeding disorders that provide a liquid flow-pass between proximal and distal balloons for bridging the circulation between the upper and lower segments of a hemorrhaging artery or blood vessel, while blocking the blood flow to the hemorrhaging middle segment(s) of the artery or blood vessel between the two or more balloons. When only one balloon is inflated, these devices can create a pressure gradient between proximal or distal and middle segments of the artery or blood vessel. These devices are useful for controlling proximal artery blood pressure, preventing distal ischemia-reperfusion injury, identifying the bleeding location, controlling the bleeding, repairing and remodeling vascular structures, extending resuscitative endovascular balloon occlusion of the aorta (REBOA) use duration, and performing fluid resuscitation.
Catheters for extracorporeal circulation
Catheter and catheter assemblies for extracorporeal circulation of body fluids, such as blood, are described. A catheter includes a septum that divides an internal lumen into fluidicly isolated drainage and infusion lumens. The infusion lumen extends along only a portion of the axial length of the catheter and terminates at an infusion opening defined by the circumferential wall of the elongate member of the catheter. The drainage lumen extends the full axial length of the catheter and is laterally accessible via first and second sets of drainage openings.
CANNULA FOR APICAL CANNULATION
Cannulas for apical cannulation and methods of making and using the same are provided. The cannula includes a first elongated body defining a primary lumen, a second elongated body defining a first secondary lumen, a third elongated body defining a second secondary lumen, and a fourth elongated body defining a third secondary lumen. The primary lumen is configured to allow blood to flow therethrough. The first secondary lumen is configured to inflate an inflatable body, which is configured to engage an aortal wall proximate the aortic valve of the patient's heart to define a treatment space. The second secondary lumen is configured to selectively remove blood from the treatment space or introduce a cardioplegic solution into the treatment space. The third secondary lumen is configured to administer active decompression of the left ventricle of the patient's heart via suction.
BALLOON CATHETER AND METHODS OF MANUFACTURING THE SAME
A balloon catheter is provided with a main tube and an air tube therein. The main tube is provided with a central lumen to allow the balloon catheter to travel across and be guided along a guidewire during insertion into a vasculature of a patient. The air tube is configured to transfer fluid, such as air, to a balloon for inflating and deflating the balloon. The air tube can be embedded within the inner and outer surfaces of the main tube. Holes are cut into the main tube and a portion of the air tube to expose the air tube to the environment outside of the main tube. The holes allow for fluid communication between the air tube and the balloon. The holes are cut or sheared at a direction that is lateral to the longitudinal direction of the catheter tube.
PERCUTANEOUS CATHETER AND METHOD OF USING PERCUTANEOUS CATHETER
A catheter for percutaneous cardiopulmonary support has a lumen through which blood flows to a living body. The catheter comprises a catheter tube including a tubular reinforcing body including a plurality of wires braided into a mesh shape and a resin layer provided so as to cover the reinforcing body. A plurality of side holes are formed at a distal end of the catheter tube to communicate the lumen with the outside of the catheter tube. The side holes allow the blood flowing through the lumen to flow out in a direction intersecting an axial direction of the catheter tube when the catheter tube is indwelled. The plurality of side holes preferably may be spirally arranged in a circumferential direction of the tube.
DRUG ASSISTED WOUND DRAINAGE LINE
The wound drainage apparatus for drug-assisted removal of bodily fluids includes a double-lumen tubing member connected to a customizable branched tubing member for placement in a wound cavity. A perforated inner tube connected to an anticoagulant drug delivery pump and a solid outer tube connected to a fluid drainage vacuum make up the double-lumen tubing member. The branched tubing member includes a plurality of secondary wound cavity tubes branching away from a primary wound cavity tube. The apparatus disclosed herein improves upon current drainage systems by preventing occlusions produced by blood clots forming in fluid drainage tubes.
Fenestrated infusion balloon catheter and methods of use
A dual-lumen injection catheter is equipped with a distal balloon featuring one or more fenestration or openings on the distal portion thereof. This allows injection of contrast agent in parallel to the injection of embolic agent and better control over the delivery of the therapeutic agent for cancer treatments, bleeding or other purposes.
Device for treating human keratinous material, in particular with the aid of an electric current
A device for treating human keratinous material, in particular with the aid of an electric current. The device includes a reservoir containing a composition, in particular cosmetic or dermatological, to be applied to the keratinous material, and an end fitting for the application of the composition contained in the reservoir, the end fitting comprising a plurality of application members and a distributor. The distributor includes at least one storage cavity for the composition and supply orifices to conduct the composition from the storage cavity or cavities to the application members, and the distributor being configured so that the flow rate of the composition arriving at the application members is identical to within 20% for at least two application members, better for each application member.
Implantable intraventricular sampling and infusion access device
In some embodiments, a device may include an intraventricular access device and an infusion device. The intraventricular access device may include more than one catheter and a container. In some embodiments, the catheter may include an aspiration lumen and an infusion lumen. A distal end of the intraventricular portion of the catheter may be positionable, during use, in a subject's brain fluid. In some embodiments, the container may be coupled to a proximal end of the aspiration lumen. The proximal end of the aspiration lumen may be in fluid communication with the container. In some embodiments, the container may include a barrier positioned between a proximal opening of the aspiration lumen and at least a portion of the infusion lumen adjacent to and/or associated with the container. The barrier may inhibit penetration of a surgical instrument.
Systems and methods for thrombolysis and delivery of an agent
A system for aspirating thrombus and delivering an agent includes an aspiration catheter having a supply lumen having a proximal end, a distal end, and a wall, and an aspiration lumen having a proximal end, an open distal end, and an interior wall surface adjacent the open distal end, and at least one orifice at or adjacent the distal end of the supply lumen, in fluid communication with the aspiration lumen and located proximally of the open distal end of the aspiration lumen, wherein the at least one orifice is configured to create a spray pattern that is caused to impinge on the interior wall surface of the aspiration lumen such that the spray pattern upon impinging on the interior wall surface is caused to transform into at least a substantially distally-oriented flow capable of exiting the open distal end of the aspiration lumen.
