US4464175A — Multipurpose tamponade and thrombosclerotherapy t…

Claim 1

Independent Claim 152 words

A multipurpose tamponade and thrombosclerotherapy tube comprising: an elongated transparent tube including a closed end and an opposite open end having at least one window aperture in the tube spaced from the closed end thereof, an inflatable balloon mounted over the tube at a spaced interval from the window aperture, a catheter bonded to the tube and extending therealong, said catheter having one end within the balloon and having side openings spaced at intervals along said end within the balloon, a substantially cylindrical cap mounted to said open end of the tube and extending outwardly therefrom and having a catheter coupling opening in the cylindrical wall thereof, and, a flexible nipple diaphragm mounted over the extending open end of said cap, said diaphragm having a closable aperture to permit entry into the tube and provide an effective tube seal said diaphragm further permitting release of pressure in the tube through said aperture.

Claim 2

Dependent Claim 152 words

A multipurpose tamponade and thrombosclerotherapy tube comprising: an elongated transparent tube including a closed end and an opposite open end having at least one window aperture in the tube spaced from the closed end thereof, an inflatable balloon mounted over the tube at a spaced interval from the window aperture, a catheter bonded to the tube and extending therealong, said catheter having one end within the balloon and having side openings spaced at intervals along said end within the balloon, a substantially cylindrical cap mounted to said open end of the tube and extending outwardly therefrom and having a catheter coupling opening in the cylindrical wall thereof, and, a flexible nipple diaphragm mounted over the extending open end of said cap, said diaphragm having a closable aperture to permit entry into the tube and provide an effective tube seal said diaphragm further permitting release of pressure in the tube through said aperture.

Claim 3

Dependent Claim 37 words

A multipurpose tamponade and thrombosclerotherapy tube in accordance with claim 1 wherein: the window aperture comprises a pair of directly opposed elongated apertures having rounded end portions with the elongation parallel to the axis of the tube.

Claim 4

Dependent Claim 57 words

A multipurpose tamponade and thrombosclerotherapy tube in accordance with claim 2 wherein: the tube is of polyvinyl material and of uniform diameter, and the open end includes an end portion of enlarged diameter adjacent the open end to receive the cap, said end portion being formed by the tube folded back upon itself for a predetermined distance.

Claim 5

Dependent Claim 38 words

A multipurpose tamponade and thrombosclerotherapy tube in accordance with claim 1 further including: silk ties at each end of said balloon for securing said balloon to the tube, and, means coupled to the catheter for inflating the balloon.

Claim 6

Dependent Claim 27 words

A multipurpose tamponade and thrombosclerotherapy tube in accordance with claim 1 wherein: said tube includes indicia located therealong for determining the position of said tube during use.

Claim 7

Dependent Claim 69 words

A multipurpose tamponade and thrombosclerotherapy tube in accordance with claim 1 further including: an irrigating and drainage system coupled to the open end of said tube, said nipple diaphragm having been removed, said system comprising a "T" tube coupling connected to the open tube, a drainage tube connected in line to the other end of the coupling and an irrigating system connected to the base of the "T" tube.

Claim 8

Dependent Claim 34 words

A multipurpose tamponade and thrombosclerotherapy tube in accordance with claim 6 wherein: the irrigating system includes an adaptor connected into the base of the "T" tube when the irrigating system is not in use.

Claim 9

Dependent Claim 68 words

A multipurpose tamponade and thrombosclerotherapy tube in accordance with claim 2 wherein: the window apertures are each located 1.5 cm. from the closed end of the tube and each measures 0.5 cm. by 2.5 cm. and the inflatable balloon is located 5 cm. from the window apertures along the tube and wherein the tube comprises an inner diameter of 1.3 cm. and an outer diameter of 1.7 cm.

Claim 10

Dependent Claim 24 words

A multipurpose tamponade and thrombosclerotherapy tube in accordance with claim 1 further including: suction means coupled to the catheter opening in the cylindrical cap.

Claim 11

Independent Claim 186 words

The method of performing endoscopic thrombosclerosis for the emergency treatment of bleeding esophageal varices in patients comprising the steps of: providing an elongated transparent tube having a closed end and an open end with at least one window aperture in the tube spaced from the closed end, an inflatable balloon mounted over the tube at a spaced interval from the window aperture and a catheter bonded to the tube and having an opening within the balloon for inflation purposes and further including a cap and a flexible nipple diaphragm with a sealable aperture mounted over the cap at the open end of said tube, inserting an endoscope through the sealable aperture in the diaphragm and advancing the endoscope to the tube window to view the presence of blood, inflating the balloon to a predetermined pressure to minimize blood flow through the paraesophageal varices, moving the outer tube with the balloon deflated until the esophagogastric junction is located through the window, providing a needle injector for injection of the varix, and delivering one or two varices into the windows with slight rotating movements applied to the tube.

Claim 12

Independent Claim 186 words

The method of performing endoscopic thrombosclerosis for the emergency treatment of bleeding esophageal varices in patients comprising the steps of: providing an elongated transparent tube having a closed end and an open end with at least one window aperture in the tube spaced from the closed end, an inflatable balloon mounted over the tube at a spaced interval from the window aperture and a catheter bonded to the tube and having an opening within the balloon for inflation purposes and further including a cap and a flexible nipple diaphragm with a sealable aperture mounted over the cap at the open end of said tube, inserting an endoscope through the sealable aperture in the diaphragm and advancing the endoscope to the tube window to view the presence of blood, inflating the balloon to a predetermined pressure to minimize blood flow through the paraesophageal varices, moving the outer tube with the balloon deflated until the esophagogastric junction is located through the window, providing a needle injector for injection of the varix, and delivering one or two varices into the windows with slight rotating movements applied to the tube.

Claim 13

Dependent Claim 32 words

The method in accordance with claim 10 wherein: the pressure in the balloon is increased once the varix injection has been made and said pressure is maintained for a predetermined time interval.

Claim 14

Dependent Claim 25 words

The method in accordance with claim 10 further including the steps of: performing gastric lavage at the same time that controlled esophageal tamponade takes place.
