Abstract
Abstract Improved intravascular balloon catheters for the delivery of embolic agents and devices such as coils to wide-neck aneurysms. In one embodiment, the present invention provides a balloon catheter having a combined guide wire/delivery lumen and a lateral delivery hole. The balloon may comprise a multi-lobed design with the delivery hole disposed between adjacent balloon lobes. The balloon catheter preferably includes a diversion member disposed in the combined lumen to cause the embolic device to divert from the combined lumen, through the delivery hole, and into the wide-neck aneurysm. In another embodiment, the present invention provides a balloon catheter having a shaft including a shaft tube and a co-extending embolic delivery tube. The delivery tube terminates proximal of the distal end of the shaft tube for added flexibility, and the balloon may inflate eccentrically to push the distal opening of the delivery lumen adjacent the opening of the wide-neck aneurysm.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
81 words
An intravascular balloon catheter for the delivery of an embolic device to an aneurysm, the balloon catheter comprising: an elongate shaft having a proximal end, a distal end, an inflation lumen extending therethrough and a combined guide wire/delivery lumen extending therethrough; an inflatable balloon connected to the distal end of the elongate shaft; and an embolic device delivery hole extending through a wall of the elongate shaft, the delivery hole providing a delivery path from the combined lumen to the aneurysm.
Claim 2
Dependent Claim
81 words
An intravascular balloon catheter for the delivery of an embolic device to an aneurysm, the balloon catheter comprising: an elongate shaft having a proximal end, a distal end, an inflation lumen extending therethrough and a combined guide wire/delivery lumen extending therethrough; an inflatable balloon connected to the distal end of the elongate shaft; and an embolic device delivery hole extending through a wall of the elongate shaft, the delivery hole providing a delivery path from the combined lumen to the aneurysm.
Claim 3
Dependent Claim
37 words
An intravascular balloon catheter as in claim 1 , wherein the balloon defines a plurality of balloon lobes and wherein the delivery hole extends through the wall of the elongate shaft between the plurality of balloon lobes.
Claim 4
Dependent Claim
46 words
An intravascular balloon catheter as in claim 2 , further comprising a diversion member disposed in the combined lumen, the diversion member causing an embolic coil advanced through at least a part of the combined lumen to divert from the combined lumen into the delivery hole.
Claim 5
Dependent Claim
20 words
An intravascular balloon catheter as in claim 3 , wherein the diversion member includes a guide wire passage extending therethrough.
Claim 6
Dependent Claim
17 words
