Inverting temporary valve sheath
First Claim
1. A temporary valve device, comprising:
- a sheath having a first section and a second section, said first section attached to a distal end of said second section;
a temporary valve having a first valve end and a second valve end, said first valve end fixedly attached to an outer circumference of said first section of the sheath; and
an attachment mechanism detachably connecting said second valve end of said temporary valve to said outer circumference of the first section of the sheath.

Abstract
A percutaneous device including a temporary valve attached to a sheath, the sheath having an inverting section for delivery and removal thereof from a blood vessel. The sheath is inverted for delivery, housing the valve between inverted layers thereof. To deploy said valve, the sheath is everted to position the temporary valve on an outer surface thereof. The temporary valve and sheath are reversibly movable between inverted and deployed configurations. Upon eversion, the temporary valve assumes a radially expanded canopy shape having an outer diameter selected to contact the vessel wall and allow blood flow in only one direction. The temporary valve may be removed by releasing one end of the valve from the sheath, flattening the temporary valve along the longitudinal axis of the sheath. Also provided is a temporary valve system comprising a dilator for inverting and everting the sheath, said dilator being removably connected to the sheath.

21. A temporary valve device, comprising:
-
a sheath having a first section and a second section, said first section attached to a distal end of said second section; a temporary valve attached to an outer surface of said first section, said temporary valve extending from a first valve end to a second valve end; an attachment mechanism reversibly connecting said temporary valve to said first section; and a first control wire extending through said valve device and having first and second free ends located outside of said valve device, wherein a proximal retraction of said first and second free ends moves said first section and temporary valve to an inverted delivery configuration.

32. A temporary valve device, comprising:
-
a sheath having a first section and a second section, said first section attached to a distal end of said second section; an invertible temporary valve having a first valve end and a second valve end, said first valve end fixedly attached to an outer circumference of said first section of the sheath and said second valve end detachably connected to said outer circumference of said first section of the sheath; and wherein said temporary valve is reversibly movable between an inverted delivery configuration and a deployed canopy configuration, wherein, in said delivery configuration, said first section is inverted into said second section and wherein in said deployed configuration, said first section is moved distally out of said second section to permit radial expansion of said temporary valve. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)
