  • Publication number: 20120089128
    Abstract: The present disclosure describes a trans-gastric jejunal tube (TJ) that avoids migration of the tube upwardly into the stomach. It does this because of alternating stiff and flexible sections. The stiffer sections resist migration and the more flexible or softer portions allow the tube to bend around the pyloris sphincter and into the jejunum. This also allows for a larger diameter feeding lumen than would otherwise be the case.

  • Patent number: 8142394
    Abstract: 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.

  • Publication number: 20120029483
    Abstract: A connector for coupling to a base of an indwelling catheter or tube device equipped with a circular hub having a radius, a top surface, a side surface, and a circumferential recess defined in the side surface. The connector has a resilient assembly that includes a plurality of release buttons extending from the resilient assembly and may optionally include a head. The connector may also include a conduit defining a fluid pathway for transferring fluids through the connector. Each release button has a first portion including a finger contact zone and a second portion including a catch. The catch is configured to releasably engage the circumferential recess defined in the side surface of the circular hub. The connector is coupled to the circular hub by positioning the connector on the circular hub and depressing the connector until the catches engage the circumferential recess defined in the side surface of the circular hub such that the connector is configured to rotate completely about the circular hub.

  • Publication number: 20110152762
    Abstract: A catheter assembly incorporating a pre-biased indicator, the assembly includes a catheter having a proximal end, a distal end, and catheter walls defining a catheter lumen. The assembly further includes a base located at the proximal end of the catheter, the base defining an opening to the catheter lumen, the base having a first end and a second end. An inflatable balloon having a predetermined fill volume is located at a distal end of the catheter. An inflation valve is located on the base; the inflation valve is in fluid communication with the balloon through an inflation lumen defined by the catheter walls. The pre-biased indicator located on the base in fluid communication with the balloon is configured to provide a discrete visual signal that the pressure of a fluid in the balloon is different from a predetermined level of pressure or the volume of the balloon is different from the predetermined fill volume.

  • Patent number: 7850714
    Abstract: The invention describes an apparatus and method of use for anchoring two or more body tissue layers to one another. The apparatus includes a plurality of individual anchor segments that are placeable within a body cavity. The segments may assume a first relaxed state wherein the segments are movable relative to each other and alignable along an initial longitudinal axis for initial placement of the apparatus through the body tissue layers. Once placed within the body cavity, the anchor segments are manipulated into a second rigid state with an actuator wherein the segments assume a rigid configuration at a transverse angle relative to the initial longitudinal axis.

  • Publication number: 20100185159
    Abstract: There is provided an enteral feeding assembly having a base and a connector. The base has a catheter with a lumen for communication with a body lumen. The base also has an opening with a predetermined shape on its proximal side that also communicates with the catheter lumen. The connector has a key configured to complement the predetermined shape of the opening in the base, which occurs desirably in one position only, so that the connector and base may be joined together. The connector is also connected to a feeding tube that provides a nutrient solution from a replaceable feeding bag. Once the connector is in position in the base, liquid may from the bag to the body lumen. Once in position, the connector may rotate 360 degrees relative to the base before being again in the installation/removal position.

  • Publication number: 20100185155
    Abstract: An enteral feeding assembly is described which includes a base and a catheter positioned through the base. A portion of the catheter extends distally away from the base, and has a retainer provided on a distal end of the catheter. The retainer includes a plurality of struts having a flexible, preformed configuration which cooperate to form at least a portion of a spherical shape with openings between the struts. A shroud is positioned over at least a proximal portion of the struts to prevent the struts from causing irritation or embedding in a body lumen. The retainer is movable between an insertion configuration and a deployed configuration. An obturator and actuator are used to move the retainer between positions. A method for inserting and removing an enteral feeding assembly is also provided.

  • Publication number: 20100138975
    Abstract: A protective garment, such as a surgical gown, includes a garment body defining sleeves. A cuff may be secured at respective ends of the sleeves. An elastic fiber layer is disposed on the sleeves beginning at the sleeve or cuff. The elastic fiber layer has a high friction surface such that an end of a glove pulled over the elastic fiber layer is inhibited from rolling or sliding back over the elastic fiber and down the sleeve. The elastic fiber may be formed of a polyolefin or other polymers according to known processes and may include a dye or colorant that may be used to indicate the fluid protection level of, for example, a surgical gown.
