Abstract: A hub for a sheath, catheter, or other tubular device includes a tubular hub body including first and second ends, and a lumen extending therebetween and surrounding a central longitudinal axis, the lumen having a first cross-sectional area sized for receiving a medical device therethrough. A valve is secured within the lumen that includes an elastomeric valve body including a passage extending therethrough between front and rear surfaces thereof and offset from the central axis. The valve body defines a second cross-sectional area larger than the first cross-sectional area in a relaxed state in which the passage defines an oval shape, and is secured within the lumen in a compressed state in which the passage is compressed to a closed configuration for sealing the passage from fluid flow. The passage is resiliently expandable to accommodate receiving an instrument therethrough while providing a seal around the instrument.

Abstract: A tearaway sheath assembly (100) having a splittable sheath tube (102) a splittable hub (110), a splittable valve (150) and a split cap (180).

Abstract: The invention is directed to a trocar adapted to form a seal around a surgical instrument, the trocar comprising a cannula having an axis extending between a proximal end and a distal end; a housing having a proximal wall and forming with the cannula a working channel sized and configured to receive the instrument; a septum seal disposed in the housing and extending transverse to the axis of the cannula across the working channel, the septum seal having a normal state when the instrument is absent from the working channel and a stretched state when the instrument is being withdrawn from the working channel; portions of the proximal wall of the housing defining an orifice sized and configured to receive the instrument into the working channel; and an elastomeric ring-shaped projection extending axially distally between the proximal wall and the septum seal, the ring-shaped projection having an axial length adapted to deform to prevent inversion and binding of the septum seal and the orifice upon withdrawal of the surgical instrument. In particular, the septum seal is prevented from reaching the orifice in the proximal wall of the housing when the instrument is withdrawn. The projection may be bonded, insert-molded, or compressively fitted to the proximal wall of the housing. The projection may be formed of an elastomeric material such as natural or synthetic rubber. The projection may further comprise a plurality of portions or fingers extending axially distally from the proximal wall, each of the extending portions or fingers may further include a living hinge. In another aspect, the ring-shaped projection may be formed on the surface of the septum seal instead of the proximal wall of the housing. That is, the ring-shaped projection may be formed to extend axially proximally from the surface of the septum seal toward the proximal wall of the housing.
