Abstract
A medical device for accessing body tissue or fluid is disclosed. The medical device may include an introducer sheath and a valve that impedes the flow of fluid through the introducer sheath. An assembly for selectively coupling components of a medical device is also disclosed. The assembly may comprise two components configured to engage with one another by at least a snap fit-type connection. This connection may facilitate disengagement of the two components via actuation of a release mechanism.
Claims19
An introducer sheath for use during a percutaneous biopsy procedure, the introducer sheath comprising:
- a first elongate member comprising a lumen that extends through the first elongate member, the lumen configured to accommodate a portion of a second elongate member;
- and
- a first hub disposed adjacent a proximal end of the first elongate member, the first hub configured to selectively couple to the second elongate member;
- wherein the lumen extends through the first hub.
A hub assembly for selectively coupling two components of a medical device, the hub assembly comprising:
- a first component comprising a first lumen and a proximal end;
- and
- a second component comprising a distal region configured to frictionally engage the proximal end of the first component;
- wherein disposition of the distal region of the second component into engagement with the proximal end of the first component couples the second component to the first component via at least a snap fit-type connection.
A method of selectively coupling components of an introducer sheath, the method comprising:
- obtaining an introducer sheath, the introducer sheath comprising a first elongate member, wherein a lumen extends through the first elongate member;
- disposing a second elongate member relative to the first elongate member, such that a portion of the second elongate member is disposed within the lumen;
- and
- coupling the second elongate member to the first elongate member by longitudinally translating the second elongate member with respect to the first elongate member.
The method of claim 19, wherein uncoupling the second elongate member from the first elongate member is performed with one hand.
