Abstract:
1. A hub for a sheath, catheter, or other tubular device, comprising: a tubular body comprising a first end, a second end, 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; and a valve secured within the lumen, the valve comprising an elastomeric valve body including front and rear surfaces extending across the lumen and a passage extending through the valve body between the front and rear surfaces and offset from the central axis, the valve body defining a second cross-sectional area larger than the first cross-sectional area in a relaxed state, the passage defining an oval shape in the relaxed state, the valve secured within the lumen in a compressed state in which the passage is biased to a closed configuration for substantially sealing the passage from fluid flow therethrough, the passage resiliently expandable to accommodate receiving an instrument therethrough while providing a substantially fluid tight seal around the instrument, wherein the valve body comprises a radial protrusion located radially from the passage relative to the central axis that imposes a radially inward force on the passage in the compressed state for biasing the passage to the closed configuration.
