摘要： 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.

摘要： A balloon catheter device includes a catheter having a proximal end, a distal end, and catheter walls defining a catheter lumen. An inflatable balloon is located at a distal end of the catheter and is inflated through an inflation valve located on a base. An internal cavity is defined in the base and is in fluid communication with the inflatable balloon. 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.

摘要： An inflatable retention system for an enteral feeding tube having a base deployed outside the human body and an indwelling retainer which is deployed within a lumen or cavity of the body by insertion through a stoma from outside the body. The retention system includes a tube having a proximal end, a distal end, an external tube diameter, and tube walls defining a feeding lumen and an inflation lumen. The retention system also includes an inflatable balloon located at a distal end of the tube in fluid communication with the inflation lumen, the balloon having thin, flexible walls, a predetermined spheroid shape, and a volume at which a fluid in the balloon is under no pressure such that upon inflation with a fluid to pressurize fluid in the balloon, the balloon assumes a stable spheroid shape and exhibits a substantially linear pressure versus volume curve.

摘要： 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.

摘要： 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. The connector is decoupled from the hub by pressing the release buttons to reversibly displace the respective catches radially to disengage from the circumferential recess.

摘要： A feeding tube assembly having an improved feeding tube body composed of a tube wall having an external tube surface and an internal tube surface, a proximal end, a distal end separated from the proximal end by a length, and a distal tip region. The internal tube surface defines a feeding passageway extending the proximal end to the distal tip region. The tube body has a first cross-sectional profile from the proximal end to the distal end and at least a second cross-sectional profile from the distal end to the distal tip region. In the first cross-sectional profile, the external tube surface defines an external circumference and the internal tube surface defines a generally non-circular internal perimeter dividing the tube wall into one thin-walled portions and thick-walled portions. In the second cross-section profile, the external tube surface defines an external circumference and the internal tube surface defines an internal circumference.

摘要： 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.
