Abstract
A catheter insertion sheath assembly (100) including a tubular sheath body (106) having a proximal end (102), a distal end (104), and a hollow passage (107) extending between the proximal end and the distal end. A handle portion (110,114) is disposed at the proximal end of the tubular sheath. A clamp (120;300:400) extends from the handle portion for releasably closing the sheath prior to insertion of a catheter thereinto and includes a relatively movable portion (130) or portions (310,310′;410,410′) that is or are movable between an open position and a closed position, wherein, when the clamp is in the open position, fluid may flow through the hollow passage between the proximal end and the distal end and when the clamp is in the closed position, fluid flow is restricted through the hollow passage between the proximal end and the distal end. A method includes inserting a catheter into the sheath upon the clamp'"'"'s movable portion(s) being moved to an open position

16. A method of operating a pinch clamp for releasably pinching off fluid flow through a catheter insertion sheath, comprising:
-
providing a clamp over a catheter insertion sheath, wherein the catheter insertion sheath includes a longitudinal axis extending therethrough;
using a thumb on one hand to bias a first engagement portion of the clamp toward the longitudinal axis; and
using at least one finger on the hand to bias a second engagement portion of the clamp toward the longitudinal axis, such that the first engagement portion releasably engages the second engagement portion and the flexible conduit is pinched off by the first engagement portion and the second engagement portion. - View Dependent Claims (17)

18. A method of inserting a catheter into a catheter sheath, wherein the catheter sheath comprises a proximal end, a distal and a sheath clamp disposed proximate to the proximate end, the method comprising:
-
inserting a catheter sheath into a blood vessel of a patient;
securing the sheath clamp to the sheath to restrict fluid flow between the proximate end and the distal end of the sheath;
inserting a catheter into the proximal end of the sheath and advancing the catheter toward the sheath clamp;
releasing the sheath clamp from the sheath;
advancing the catheter through the sheath to the distal end of the sheath; and
removing the sheath from the blood vessel. - View Dependent Claims (19, 20, 21, 22, 23, 24)
