[0132] Unless defined differently, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. All documents referred to herein are also incorporated herein by reference. All US patents and patent applications referred to herein are hereby incorporated by reference in their entirety, including the drawings.

[0133] The articles "a" and "an" as used herein both mean one or more than one, ie, at least one of the grammatical objects of an object. For example, "a lumen" or "a lumen" means one lumen or more than one lumen.

[0134] The recitation of numerical ranges by endpoints includes all integers within that range and, where appropriate, the fractions subsumed within that range (e.g., 1 to 5 may include 1, 2, 3, 4 when indicating a number of lumens ; when referring to eg measurements, 1 to 5 can also include 1.5, 2, 2.75 and 3.80). Endpoint enumeration also includes the value of the endpoint itself (eg, 1.0 to 5.0...

Abstract

The present invention provides a kit for delivering catheter brachytherapy to a subject comprising a medical balloon catheter (1) having a proximal (2) and distal (3) end, comprising a elongated catheter tube (5) with an inflation lumen (21) extending therewithin and at least one inflatable balloon (4, 4') towards the distal end (3) in fluid communication with the catheter tube (5) inflation lumen (21), the catheter tube (5) configured to unfold from a kinked condition permitting the inflation lumen (21) to slidably receive a removable inner tube (6), the inflation lumen (21) configured to carry inflation fluid to the least one inflatable balloon (4, 4') in the presence of the removable inner tube (6); and a removable inner tube (6) having an elongated body, an open (9) proximal end (7), a closed (10) distal end (8), and a source wire lumen (22) extending therewithin, wherein the removable inner tube (6) is configured for insertion into and removal from at least part of the length of the inflation lumen (21), and the source wire lumen (22) configured to receive a source wire (19) bearing a therapeutic radiation source (20). It also provides a method for delivering catheter brachytherapy to a subject.

Description

technical field [0001] The invention relates to the field of catheter brachytherapy for patients. More specifically, the present invention relates to a brachytherapy catheter whose stiffness can be adjusted depending on the treatment phase. Background technique [0002] Catheter brachytherapy provides patients with internal radiation therapy treatment whereby a radiation source is advanced along a catheter whose tip is inserted near the treatment area. It is commonly used to treat cancers of the esophagus, uterus, and brain and neck. Catheter brachytherapy is well known in the art. Clinical studies have shown that brachytherapy is an effective treatment for reducing tumor size and growth velocity in both palliative care and curative indications. [0003] For some indications, as in esophageal cancer, catheter brachytherapy requires a skilled physician to introduce a guide wire into the patient using a visual instrument, such as an endoscope, to ensure the correct course a...
