Abstract
An introducer sheath and methods of making the introducer sheath are described. The introducer sheath may include a hub portion and a tubular portion. The hub portion may include a substantially non-planar valve portion in a relaxed state. The valve portion may include an aperture configured to receive a medical device. A hub portion may be formed using a forming device. An aperture may be formed through a distal surface of the valve portion. A valve portion may be formed in a cap defining a cavity sized to elastically receive a proximal end of the hub portion.
Claims20
An introducer sheath, comprising:
- a hub portion;
- and
- an elongate tubular portion extending from said hub portion and a lumen extending from a distal end toward a proximal end of said elongate tubular portion, said lumen including a plurality of protrusions and a plurality of depressions, wherein said protrusions and/or depressions vary in angular orientation with respect to said longitudinal axis between a proximal end and a distal end.
An introducer sheath, comprising:
- a hub portion;
- and
- an elongate tubular portion extending from said hub portion and having a first lumen and a second lumen, said first lumen including a plurality of first protrusions and a plurality of first depressions and said second lumen including a plurality of second protrusions and a plurality of second depressions, said plurality of first protrusions and said plurality of first depressions differing from said plurality of second protrusions and said plurality of second depressions, wherein said first protrusions and/or first depressions vary in angular orientation with respect to said longitudinal axis between a proximal end and a distal end.
A method for performing a medical procedure, the method comprising:
- introducing a sheath into a lumen of a patient, the sheath having a first unexpanded dimension and an irregular wall surface;
- and
- inserting a first medical device having an outer dimension into the lumen through the sheath to perform a medical procedure, wherein at least a portion of a tubular member of the sheath expands to a second expanded dimension to accommodate the outer dimension of the first medical device.
