Abstract
The invention features a needle defining a flowpath, a housing comprising a proximal end and a distal inner seat leading to and defining a lumen, and a viscous material contained within the housing. The needle is slidable through the housing and the viscous material contained therein. The viscous material is fluid enough for the needle to slide therethrough, yet semi-solid enough to conform to the housing distal inner seat so as to form a seal thereat and prevent flow of fluid or air through the lumen.
