Abstract:
1. A relatively soft seal member for assembly within a lumen of an elongate medical device/instrument, the seal member comprising: a single bulk of a material including a distal face; a bore formed in the bulk of material and extending longitudinally therein from a proximal opening of the bore to a distal terminal end of the bore, the distal terminal end of the bore being proximally offset from the distal face of the bulk of material, the bore including a funnel-like segment that extends between the proximal opening and the distal terminal end of the bore and tapers down in size from a proximal diameter thereof to a distal diameter thereof; wherein the bore further includes a cylindrical segment extending between the distal diameter of the funnel-like segment and the distal terminal end of the bore, a diameter of the cylindrical segment being substantially constant along a length thereof and substantially equal to the distal diameter of the funnel-like segment; and a slit extending proximally through the bulk of material, from the distal face of the bulk of material and into the funnel-like segment, the slit having a size, or radial extent, that is greater than the distal diameter of the funnel-like segment of the bore.
