Handheld Resector Balloon System

摘要

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.

主权项

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 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 lumen of said catheter for supplying fluid thereto; 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.
