Handheld resector balloon system
First Claim
1. A resector balloon system, comprising:
- a handheld pump;
a hub mounted to said handheld pump;
a catheter with a proximal portion and a distal portion, wherein the proximal portion of said catheter is coupled to said hub; and
at least one balloon at the distal portion of said catheter, said balloon at least partially enclosing an inflation chamber and having a resecting surface for resecting biological material;
wherein said catheter has a first lumen in fluid communication with the inflation chamber of said balloon for supplying fluid thereto;
wherein said hub has an inflation port in fluid communication with the first lumen of said catheter for supplying fluid thereto;
wherein said catheter has a second lumen;
wherein said hub has a delivery port in fluid communication with said second lumen for delivering a therapeutic and/or diagnostic agent to the distal portion of said catheter, wherein the delivery port is also in fluid communication with a source of the therapeutic and/or diagnostic agent; and
wherein said handheld pump is in fluid communication with said inflation port such that the supply of fluid by said pump in pulsed fashion repeatedly inflates and deflates said balloon such that the resecting surface resects the biological material.

Abstract
A handheld resector balloon system includes a balloon catheter with a resecting surface and hub coupled to a handheld pump. The hub includes an inflation port that supplies fluid to a first lumen of the catheter to repeatedly inflate and deflate the balloon in pulsed fashion to resect biological material. The hub may also include a delivery port for delivering an agent, such as drugs, to a second lumen of the catheter for delivery to the distal end of the catheter. The hub may also include an aperture for inserting a device, such as an imaging device, into the second lumen of the catheter. In some embodiments, an imaging module is coupled to a handheld pump, which may include a light source for supplying light, and image circuitry for converting an optical signal from the imaging device to electrical data to be output to a computer.
