Balloon catheter with delivery side holes

A medical device, comprising:

• an inner tubular member having a proximal opening, a distal opening, and an inner lumen extending therethrough;
• a sheath disposed over the inner tubular member;
• wherein an annular lumen is defined between the sheath and the inner tubular member;
• wherein the sheath includes a delivery port in fluid communication with the annular lumen;
• and
• a balloon coupled to the sheath at a position that is distal of the delivery port;
• wherein the inner lumen is in fluid communication with the balloon;
• wherein the distal opening of the inner tubular member is located at a position that is distal of the balloon.

A balloon catheter, comprising:

• a first independent tube having a proximal end and a distal end;
• a second independent tube disposed within the first independent tube, the second independent tube including an inner lumen extending therethrough, proximal portion, a distal portion, and an inflation portion extending between the proximal and distal portions;
• and
• a balloon coupled to the first independent tube adjacent the distal end of the first independent tube and over the inflation portion of the second independent tube;
• wherein an annular lumen is defined between the first independent tube and the proximal portion of the second independent tube;
• wherein the first independent tube includes a distal opening located at a position that is adjacent the proximal portion of the second independent tube, the opening being in fluid communication with the annular lumen.

A balloon catheter, comprising:

• an inner tubular member having a longitudinal axis, a proximal portion, a distal portion, a fluid permeable coil extending between the proximal and distal portions;
• wherein the coil includes an interior region oriented along the longitudinal axis of the inner tubular member and a lumen;
• wherein the inner tubular member defines an inflation lumen extending from the proximal portion, through the lumen of the coil, and out of the distal portion;
• a guidewire extending through the proximal portion, the interior region of the coil, and the distal portion;
• an outer tubular member disposed over the proximal portion and the coil, and at least partially over the distal portion of inner tubular member;
• a balloon coupled to the outer tubular member adjacent the coil;
• wherein an annular lumen is defined between the outer tubular member and the proximal portion of the inner tubular member;
• and
• an outlet port formed in the outer tubular member adjacent the proximal portion, the port being in fluid communication with the annular lumen.

A medical device, comprising:

• an inner tubular member including an inner lumen extending therethrough, a proximal portion, an inflation portion, and a proximal portion;
• wherein the inner tubular member includes means for slidably receiving a guidewire;
• an outer tubular member disposed over at least a portion of the inner tubular member;
• a balloon coupled to the outer tubular member;
• wherein the inner lumen is in fluid communication with the balloon through the inflation portion;
• an annular lumen defined between the outer tubular member and the proximal portion of the inner tubular member;
• and
• a delivery port formed within the outer tubular member at position that is proximal of the balloon, the delivery port being in fluid communication with the annular lumen.
