Hemostatic agent delivery device having built-in pressure sensor

A device for indicating pressure variations due to systolic and diastolic phases of the heart comprising:

• (a) a tubular member having a proximal end, a closed distal end, and a lumen extending therebetween;
• (b) a port located at a predetermined distance proximal of said closed distal end of said tubular member, said port providing a fluid passageway from said lumen of said tubular member to an exterior of said tubular member;
• (c) pressure indicating means including a fluid tight track of a predetermined length affixed to said proximal end of said tubular member, said fluid tight track including a transparent cover, said fluid tight track being in fluid communication with said lumen of said tubular member wherebysaid tubular member is adapted to be inserted into a puncture in blood vessel wall whereby blood enters the fluid tight track;
• and
• (d) a dual syringe assembly for injecting a platelet rich product and thrombin mixture.

An apparatus for sealing percutaneous punctures in a blood vessel wall following a catheterization procedure, said apparatus adapted for use in conjunction with a tubular introducer of the type having a sheath whose distal end is insertable into a wound resulting from percutaneous puncture of said blood vessel wall, said sealing apparatus comprising:

• (a) a tubular member having a closed distal end, a proximal end and a lumen extending therebetween, said tubular member sized to slide into said tubular introducer and of a length whereby its distal end will extend out of said distal end of said tubular introducer sheath when fully inserted therein;
• (b) a port positioned proximate said distal end of said tubular member, said port providing fluid passageway from said tubular member lumen to an exterior of said tubular member;
• (c) a hub member affixed to said tubular member, the hub member having a groove of a predetermined length formed in a surface thereof, said groove having a first end and a second end, a first fluid passageway extending between said lumen and said first end of said groove and a transparent member over-lying the groove and cooperating with the groove to create a sealed track;
• and
• (d) a hemostatic seal at said proximal end of said lumen.

A method of sealing percutaneous punctures in the blood vessel of a patient following a catheterization procedure and adapted for use with a vascular introducer of the type having a sheath whose distal end is inserted into a wound resulting from the percutaneous puncture, said method comprising the steps of:

• (a) providing a tubular member having a closed distal end, a proximal end and a lumen extending therebetween, said tubular member having a port located a predetermined distance proximal of its closed distal end, said port extending between said lumen and an exterior of said tubular member and an observable blood receiving fluid tight track positioned proximate said proximal end of said tubular member, said fluid tight track being in fluid communication with said lumen;
• (b) inserting said tubular member into said tubular introducer sheath until blood movement is observed in said fluid tight track;
• (c) retracting as a unit from said puncture wound said tubular member and said tubular introducer sheath until blood movement in said fluid tight track ceases;
• and
• (d) injecting a hemostatic agent into said tubular member lumen whereby said hemostatic agent exits said port adjacent said blood vessel wall.
