InactiveCN102764170AEfficient extractionAvoid second strokeStentsSurgeryInsertion stentThrombus
The invention discloses an intravascular stent with complex functions. The intravascular stent comprises a stent main body which is mesh-shaped and can be released from and retracted to a feeding catheter, wherein a near end of the stent main body is openly conical, the middle part of the stent main body is circular tube-shaped, and a far end of the stent main body has a closed structure; and the stent main body has a mesh shape which is woven by single wires or a plurality of wires or is engraved by a laser engraving machine. The stent which is taken as an acute thrombus removal system can quickly and efficiently take out thrombi, and can also capture small thrombi which flow toward the far end so as to avoid secondary stroke caused by the thrombus blockage of the far end; the stent which is taken as a temporary stent expands intracranial blood vessels or narrow and blocked blood vessels on other parts of human bodies, plays the effects of dredging and reconstructing blood flow, and can capture small thrombi or emboli; and the stent which is taken as a long-term implanted stent performs adjuvant therapy on arterial aneurysms of furcations, and fills in a market gap. If the position of the stent is not satisfactory, the entire stent can be retracted to the feeding catheter, and is released again. The maneuverability of the stent is high, so the operation difficulty is reduced, and the surgical success rate is greatly improved.

ActiveUS8142394B1Increasing inflation pressureStentsSurgeryEnteral feedingsFeeding catheter
A balloon catheter device, for example an enteral feeding catheter, includes a catheter having a proximal end, a distal end, and catheter walls defining a catheter lumen. A base is located at the proximal end of the catheter and has an opening to the catheter lumen. An inflatable balloon is located at a distal end of the catheter and is inflated through an inflation valve located on the base. An internal cavity is defined in the base and is in fluid communication with the inflatable balloon such that fluid used to inflate the balloon to an operational fill volume fills the internal cavity as well. A translucent window is disposed over the internal cavity such that an interior volume of the cavity is externally viewable. Introduction of a colored fluid through the inflation valve to inflate the balloon results in the colored fluid also being present in the internal cavity, thereby providing an externally visual indication of the inflation state of the balloon.

Devices and methods to measure gastric residual volume (GRV) are described where at least one additive component (a GRV indicator) may be dispersed in a body lumen such as a stomach. The GRV indicator may changes a physical (chemical, electrical, thermal, mechanical, optical, etc.) characteristic within the stomach by a measureable degree. This degree of change and / or the rate of return to the previous state, may be used to determine the GRV of a patient. The determined GRV can also be used to automatically or semi-automatically control the patient's feeding rate and / or volume and / or frequency to adequately nourish the patient but avoid complications. The physical characteristic(s) may also be used to detect that the feeding catheter or tube is in the correct location (ie stomach vs lung or esophagus.

Jejunal feeding catheter

InactiveUS20110196290A1Avoid occlusionMaximizing portionMedical syringesFeeding-tubesJejunal lumenFluid infusion
An enteral catheter provides access to both the stomach and the deep jejunum for feeding, aspiration and decompression. The catheter includes a triple lumen 16Fr tube that joins to a triple lumen “Y” connector at the proximal end of the tube. The connector serves the three lumens as a source for venting air, for fluid aspiration and for fluid infusion. The catheter includes a gastro / jejunal bolus which provides a large effective recessed port size opening varying from 172 degrees around the circumference of the bolus to a maximum recess circumference of 350 degrees. The gastric aspiration lumen, the jejunal feeding lumen, and the air vent lumen, all connect to the gastro / jejunal or midport connector bolus in the stomach at the distal end of the three lumen tube. The gastric lumen and the air vent lumen both open into the stomach through a common gastric port by the midport bolus. The jejunal lumen in the 16Fr tube communicates with jejunal lumen in the jejunal tube. The midport bolus provides for the attachment of a smaller, round single lumen 8Fr lumen tube that extends into the jejunum and terminates at its distal end with a tip bolus. Both the gastric lumen and the air vent line terminate at the same point side by side into the common gastric port in the midport bolus. The gastric port is recessed to the level of its full internal lumen in the midport bolus, thereby providing a recess for maximum protection against occlusion and maximum area for outflow and inflow. The midport bolus and the jejunal port in the tip bolus include a structural arch protruding radially outwardly therefrom. The arch is effective to prevent the body segment of the bolus from bending and restricting the ports. At the distal end of the jejunal tube, the tip bolus contains an improved port that is recessed to just below the internal radius of the tube lumen to provide maximum protection against occlusion and maximum area for outflow.
