LARGE BORE SHEATH DEVICE INCLUDING COUPLING DEVICE
Various embodiments of a sheath device and related methods are described herein. In some embodiments, the sheath device can include a sheath hub and a sheath body extending from the sheath hub. The sheath body can include an inner passageway and a proximal section having a first length and a first flexibility along the first length. The sheath body can further include a distal section having a second length and a second flexibility along the second length, and the second flexibility can be greater than the first flexibility. The sheath body can further include an atraumatic tip positioned at a distal end of the sheath body, and the atraumatic tip can include a rounded distal end.
1 . A sheath device, comprising:
a sheath hub;
a sheath body extending from the sheath hub, the sheath body comprising:
an inner passageway;
a proximal section having a first length and a first flexibility along the first length;
a distal section having a second length and a second flexibility along the second length, wherein the second flexibility is greater than the first flexibility; and
an atraumatic tip positioned at a distal end of the sheath body, the atraumatic tip including a rounded distal end.
2 . The sheath device of claim 1 , further comprising:
a transition section positioned between the proximal section and the distal section, the transition section having a third length and a third flexibility that is less than the first flexibility and greater than the second flexibility.
3 . The sheath device of claim 2 , wherein the sheath body includes more than one distal section and more than one proximal section.
4 . The sheath device of claim 3 , wherein the distal sections and the proximal sections alternate along a length of the sheath body.
5 . The sheath device of claim 1 , wherein a support structure extends along a length of the sheath body, the atraumatic tip being void of the support structure.
6 . The sheath device of claim 5 , wherein the support structure includes a coil having variable pitch coiling and/or a variable number of wires comprising the coil along the length of the sheath body.
7 . The sheath device of claim 5 , wherein the support structure includes a braid having variable programmable picks per inch along the length of the sheath body.
8 . The sheath device of claim 1 , wherein the sheath body includes a radiopaque element positioned along the distal end of the sheath body and proximal to the atraumatic tip.
9 . (canceled)
10 . The sheath device of claim 1 , wherein the sheath hub is at least party formed of a translucent material for allowing viewing of internal components and/or fluid within the sheath hub.
11 . The sheath device of claim 1 , wherein the sheath hub includes a conduit adapter that is configured to couple to the sheath body and allow a conduit to couple to the sheath hub.
12 . The sheath device of claim 11 , wherein the conduit adapter includes a tubular body with at least one groove along an outer surface of the tubular body.
13 . The sheath device of claim 12 , wherein each groove of the at least one groove includes a groove length that allows a coupling element to secure the conduit to the tubular body within the groove length.
14 . (canceled)
15 . The sheath device of claim 1 , wherein the sheath hub comprises a flexible extension including a coupling device.
16 . The sheath device of claim 15 , wherein the coupling device comprises:
a coupling body;
a cap releasably couplable to the coupling body; and
a collet having a collet passageway that reduces in diameter when the collet is secured between the coupling body and the cap to thereby secure a part of a delivery device extending along the collet passageway.
17 . The sheath device of claim 16 , wherein the coupling device axially and radially secures the delivery device to the sheath device when the coupling device is in a secured configuration.
18 . A method of a sheath device, comprising:
advancing a part of the sheath device in an inner lumen of a vessel, the sheath device comprising:
a sheath hub;
a sheath body extending from the sheath hub, the sheath body comprising: an inner passageway;
a proximal section having a first length and a first flexibility along the first length;
a distal section having a second length and a second flexibility along the second length, wherein the second flexibility is greater than the first flexibility; and
an atraumatic tip positioned at a distal end of the sheath body, the atraumatic tip including a rounded distal end; and
positioning the distal section of the sheath body along the inner lumen of the vessel.
19 . The method of claim 18 , wherein the sheath body further comprises a transition section positioned between the proximal section and the distal section, the transition section having a third length and a third flexibility that is less than the first flexibility and greater than the second flexibility.
20 - 21 . (canceled)
22 . The method of claim 18 , wherein a support structure extends along a length of the sheath body, the atraumatic tip being void of the support structure.
