Abstract: ABSTRACT OF THE DISCLOSURE A continence device in the form of a cube or block of resilient foam material capable of being collapsed into a small volume condition and encapsulated in a capsule of gelatin or the like and which includes a string or cord passing through the material and connected with a traction bead engaged with a distal surface of the block or cube of foam material.          The continence device provides for voluntary trapping or blockage of gastrointestinal effluent when voluntary and natural control is lacking such as when a person has had a colostomy, ileostomy, or in other situations involving fecal incontinence.  An introducer is provided for inserting the capsule, the reduced volume soft foam material therein and the line or cord and traction bead into a body orifice such as a atomal orifice, anus or the like.  The introducer is in the form of a tubular member, such as a straw which is passed over the cord or string and has one end engaged with the capsule and is provided with a flexible section to facilitate insertion of the device into the desired body orifice with the gelatin capsule then being dissolved in the presence of body warmth and moisture to enable the compressed soft foam material to expand to a predetermined size and shape for blockage and temporary retention of gastrointestinal content in the body orifice.  Traction on the string or cord during withdrawal results in compression of the contained foam cube by means of the traction bead facilitating comfortable withdrawal of the continence device from the body orifice.

Abstract: Abstract of the Disclosure A geometrical structural system is made up of a plurality of nodes and shape-coded connectors extending therebetween, each node having a plurality of outer polygo-nal elements.  The outer edges of each element are bordered by end edges of other elements and each element has an opening therethrough corresponding to the outer side edges of each element.  Each opening extends radially into a hollow space centrally of each node.  The connectors are elongated and have opposed connecting ends with a cross-sectional configuration corresponding to a cross-sectional configuration of an opening in one of the element faces for insertion therein.  The steps involved in making the nodes includes tooling a pair of mold halves with interior cavi-ties; fastening the halves together with the interior cavi-ties confronting one another to form a common cavity symmetrical about their center; positioning slides in the common cavity, each slide corresponding to the cross-sectional configuration of a polyhedral face to be formed in the outer shell but smaller in cross-sectional size than the polyhedral face; injecting a moldable material to fill the common cavity and remaining voids between the slides; followed by withdrawing the slides from the mold cavity and disconnecting the mold halves for removal of a one-piece node.
