Catheter sheath pinch clamp
First Claim
1. A catheter insertion sheath comprising:
- a tubular sheath having a proximal end, a distal end, and a hollow passage extending between the proximal end and the distal end;
a handle portion disposed at the proximal end of the tubular sheath; and
a clamp assembly extending from the handle portion for releasably closing the sheath, the clamp assembly including at least one section in fixed relationship to the sheath adjacent thereto, and at least one section that is movable with respect to the fixed section and to the sheath, wherein the at least one movable section is translatable between an open position and a closed position, wherein, when in the open position, fluid may flow through the hollow passage between the proximal end and the distal end and when in the closed position, fluid flow is restricted through the hollow passage between the proximal end and the distal ends,wherein the clamp assembly is affixed to the handle and positioned adjacent to the sheath in such a manner that its at least one movable portion is operable with a single hand while that hand also holds the insertion sheath.

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.

2. A catheter insertion sheath comprising:
-
a flexible elongated body having a proximal end, a distal end, a longitudinal axis extending therethrough; a handle connected to the proximal end of the body; and a pinching assembly for pinching the body closed, wherein the pinching assembly extends from the handle, the pinching assembly including at least one section in fixed relationship to the sheath adjacent thereto, and at least one section that is movable with respect to the fixed portion and to the sheath, and wherein the at least one movable section is operable between an open position and a closed position. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11)

12. A catheter insertion sheath assembly comprising:
-
a catheter sheath including a generally tubular sheath body having a proximal end and a distal end; a handle fixedly connected to the proximal end of the sheath body; and a catheter sheath clamp comprising; a body having a first end connected to the sheath handle in a fixed relationship therewith and is adjacent the sheath and a second end having a slot extending through the body; and a generally planar pinch member slidingly disposed within the slot between an open position and a pinching position, wherein the pinch member includes a first pinch leg having a first tapered free end and a first connected end and a second pinch leg juxtaposed from the first pinch leg, wherein the second pinch leg has a second tapered free end and a second connected end connected to the first connected end, and wherein the pinch member is slidable within the slot between a first position wherein the first and second tapered free ends are proximate to the slot and a second position wherein the first and second connected ends are proximate to the slot. - View Dependent Claims (13, 14)
