Abstract
Abstract A generally loose-fitting tubular sheath article, such as a condom, which has a closed distal end and an open proximal end which is bounded by a knitted material that bears compressively on the sheathed member to provide retention. The knitted material may be in the form of a band which is affixed to the sheath by everting a portion of the sheath material at the proximal end over the knitted material and attaching the sheath material to itself, thereby creating a toroidal enclosure in which the knitted material is disposed. Constriction of the sheathed member is minimized by the knitted material which provides a large surface area for retentive contact.
