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.
Claims17
An introducer sheath, comprising:
- an elongate tubular portion having a longitudinal axis, said elongate tubular portion being elastically deformable about the longitudinal axis;
- and
- a hub portion, said hub portion having a substantially non-planar valve portion in a relaxed state, said valve portion having an aperture configured to receive a medical device, said aperture being substantially conical when the valve is in the relaxed state and substantially cylindrical when the valve is in a substantially planar, deformed state,
- wherein said hub portion and said valve portion are formed as a monolithic, integral, unitary member.

An introducer sheath, comprising:
- an elongate tubular portion having a longitudinal axis, said elongate tubular portion being elastically deformable about the longitudinal axis;
- and
- a hub portion and a valve portion formed as a monolithic, integral, unitary member with said tubular portion, said valve portion being substantially non-planar in a relaxed state, said valve portion having an aperture configured to receive a medical device, said aperture being substantially conical when the valve is in the relaxed state and substantially cylindrical when the valve is in a substantially planar, deformed state.
A system for accessing a body lumen, the system comprising:
- a medical device including a substantially cylindrical portion;
- and
- an introducer sheath, including:
- an elongate tubular portion having a longitudinal axis, said elongate tubular portion being elastically deformable about the longitudinal axis;
- and
- a hub portion, said hub portion having a substantially non-planar valve portion that is substantially concave in a relaxed state, said valve portion having an aperture configured to receive said substantially cylindrical portion of said medical device through said aperture, said aperture being substantially conical when the valve is in the relaxed state and substantially cylindrical when the valve is in a substantially planar, deformed state, said aperture forming a distal circumferential edge and a proximal circumferential edge, said distal circumferential edge and said proximal circumferential edge defining a sealing surface, said sealing surface being not generally parallel about a longitudinal axis through said aperture in the relaxed state, said distal circumferential edge having a first diameter and said proximal circumferential edge having a second diameter, said sealing surface configured to form a seal between said substantially cylindrical portion of said medical device and said hub in the deformed state, said first diameter being larger than said second diameter in the relaxed state and said first diameter and said second diameter being substantially the same when in the deformed state,
- wherein said tubular portion, said hub portion, and said valve portion are monolithically, integrally, and unitarily formed of a single material.
