Temporary occlusion balloon devices and methods for preventing blood flow through a vascular perforation

Abstract

A device for occluding a perforation in a blood vessel includes a catheter shaft that has a first lumen and a second lumen. The first lumen is adapted to receive at least one of a guidewire and an implanted cardiac lead, and the second lumen is adapted to receive an inflation fluid. The device further includes an inflatable balloon that is carried by the catheter shaft. The inflatable balloon is adapted to receive the inflation fluid from the second lumen, wherein the second lumen includes a cross-sectional area at a location within the catheter shaft between 0.65 mm2 and 1.90 mm2 and the inflatable balloon comprises polyurethane having a Shore A durometer of about 85 A.

         2 . The device according to  claim 1 , wherein the inflatable balloon comprises a working length of about 65 mm to about 80 mm. 
     
     
         3 . The device according to  claim 2 , wherein the inflatable balloon comprises an inflated diameter of about 20 mm to about 25 mm. 
     
     
         4 . The device according to  claim 1 , wherein the second lumen has a width of about 1.8 mm. 
     
     
         5 . The device according to  claim 1 , wherein the second lumen has a height of about 0.75 mm. 
     
     
         6 . The device according to  claim 5 , wherein the second lumen has a width of about 1.8 mm. 
     
     
         7 . The device according to  claim 1 , wherein the cross-sectional area of the second lumen comprises a crescent shape. 
     
     
         8 . The device according to  claim 7 , wherein the second lumen has a width of about 1.8 mm. 
     
     
         9 . The device according to  claim 7 , wherein the second lumen has a height of about 0.75 mm. 
     
     
         10 . The device according to  claim 9 , wherein the second lumen has a width of about 1.8 mm. 
     
     
         11 . The device according to  claim 7 , wherein the cross-sectional area of the second lumen is about 1 mm 2 . 
     
     
         12 . The device according to  claim 7 , wherein the crescent shape provides the cross-sectional area with a crescent-like cross-sectional shape, and wherein the crescent-like cross-sectional shape has a radius of about between 0.50 mm to 1.50 mm. 
     
     
         13 . The device according to  claim 12 , wherein the radius of the crescent-like cross-sectional shape is about 1 mm. 
     
     
         14 . The device according to  claim 7 , wherein the first lumen and the second lumen are non-concentrically disposed within the catheter shaft. 
     
     
         15 . The device according to  claim 14 , wherein the crescent shape provides the cross-sectional area with a crescent-like cross-sectional shape, and wherein the crescent-like cross-sectional shape has a radius of about between 0.50 mm to 1.50 mm. 
     
     
         16 . The device according to  claim 14 , wherein the radius of the crescent-like cross-sectional shape is about 1 mm. 
     
     
         17 . The device according to  claim 14 , wherein the catheter shaft comprises a first wall portion between the first lumen and the outer diameter, wherein the first wall portion is about 0.15 mm. 
     
     
         18 . The device according to  claim 17 , wherein the catheter shaft comprises a second wall portion between the second lumen and the outer diameter, wherein the second wall portion is about 0.15 mm. 
     
     
         19 . The device according to  claim 18 , wherein the catheter shaft comprises a first wall portion between the second lumen and the outer diameter, wherein the first wall portion is about 0.15 mm.
