GENERAL DESCRIPTION
The present disclosure provides a method and a kit for treating an abnormal 15 hollowed space of a subject, such as a fistula or anal fistula. The method utilizes the blood of the subject by introducing it into the abnormal hollowed space and let it clot within the abnormal hollowed space thereby forming a clot therein that enhances healing process of the abnormal hollowed space.
Thus, a first aspect of the present disclosure provides a method for treating an 20 abnormal hollowed space or a cavity of a subject. The method includes: (i) obtaining or withdrawing whole blood from the subject. This may be performed by any known manner in the art. The method further includes (ii) mixing the subject's blood with one or more coagulation agents or anti-anticoagulation agents to thereby initiate clotting process of the blood. Then, (iii) prior to complete coagulation of the blood, introducing, e.g. 25 injecting, the blood with the coagulation agent into said hollowed space and (iv) permitting the blood to coagulate in said abnormal hollowed space until a complete coagulation is obtained, and a clot is formed within the abnormal hollowed space.
In some embodiments of the method, (i) comprises withdrawing whole blood from the subject and mixing it with an anticoagulation agent. This allows to control the coagulation process and controllably induce the coagulation process at any desired time.
In some embodiments of the method, the anticoagulant is selected from a list 5 consisting of: ACD-A (Anticoagulant Citrate Dextrose, Solution A), EDTA (ethylenediaminetetraacetic Acid), EGTA (ethylene glycol tetraacetic acid), a citrate, Heparin and oxalate.
In some embodiments, the method further comprising, in the instance that said hollowed space has two or more openings, sealing one or more openings of the hollowed 10 space, e.g. a distal opening of the fistula, thus creating a sinus, namely maintaining only one opening open. This step is carried out any time prior to (iii).
In some embodiments of the method, (iv) comprises applying a medical dressing or a seal onto an opening of the hollowed space to prevent leakage of blood from the abnormal hollowed space or sinus, therefore ensuring its clotting therein.
In some embodiments of the method, said applying a medical dressing or a seal onto an opening of the hollowed space is performed after a period of between 3-15 minutes from said introducing, or after a period of between 1, 2, 3, 4, 5, 6, 7, 8 and 10, 11, 12, 13, 14, 15, 16 minutes, or about 9 minutes. It is to be noted that this period is the time frame for permitting the blood to coagulate with the abnormal hollowed space. In 20 some embodiments, this time frame can be less than 10, 9, 8, 7, 6, 5, 4, 3, 2 or at times less than 1 minute.
The term "about" should be understood as a deviation of up to 20% from the nominated value. For example, a period of about 10 minutes is referred to any period of between 8-12 minutes.
In some embodiments of the method, the one or more coagulation agents are in a liquid or a powder form.

BRIEF DESCRIPTION OF THE DRAWINGS
In order to better understand the subject matter that is disclosed herein and to exemplify how it may be carried out in practice, embodiments will now be described, by way of non-limiting example only, with reference to the accompanying drawings, in 5 which:
Figs. 1A-1D are schematic illustrations presenting different stages of a non
limiting example of the method according to an aspect of the present disclosure.
Figs. 2A-2B are flow diagrams of non-limiting examples of different embodiments of the method according to an aspect of the present disclosure.
DETAILED DESCRIPTION
The method of the present disclosure is directed for treating abnormal hollowed space existing in a subject, e.g. anal fistula. The method first requires obtaining whole blood from the subject having an abnormal hollowed space to be treated. This is 15 performed by withdrawing blood from the subject in any known method. After the blood is obtained, it is typically mixed with anti-coagulation agent for allowing to preserve the blood in a non-coagulated liquid form until it is desired to be coagulated to form a clot. Reference is now made to Figs. 1A-1C, which are schematic illustrations presenting different stages of an embodiment of the method according to an aspect of the present 20 disclosure, following the withdrawal of the blood from the patient. Fig. 1A shows a coagulation assembly 102 that includes a sealed blister 104 confining a sterile volume 106 for receiving drawn blood from the subject. The sealed blister 104 is formed of a blood injection portion 108, that can be transparent or semi-transparent to allow visualization of the process, and a coagulant-containing surface 110 that holds a liquid or 25 powder form of one or more coagulating agents or anti-anticoagulating agents. By using a piercing element 111, e.g. a syringe with an adapted needle, the blood injection portion 108 is pierced at two different locations to form two openings, as can be seen in Fig. 1A, thereby allowing the introduction of blood into the sterile volume 106 from a first opening while air escapes from the second opening. The drawn blood is then injected into the 30 sterile volume 106, as is exemplified in Fig. 1B, and the coagulating agents or anti- anticoagulating agents are mixed with the subject's blood to initiate the clotting process. The mixing can be enhanced by shaking the coagulation assembly 102, following sealing
the openings in the blood injection portion 108 to prevent leakage of blood while shaking. The blister 104 is then unsealed, e.g. by removing the sealing base 112 at the bottom of the blister 104, as is exemplified in Fig. 1C, or by piercing the blood injection portion 108 to allow withdrawal of the coagulating blood into a syringe. The process then includes 5 withdrawing the coagulating blood from the blister and then inject it into the abnormal hollowed space, e.g. fistula or into the sinus cavity in the instance that one or more of the openings of the abnormal hollowed space is sealed, e.g. by suturing procedure. This is exemplified in Fig. 1D, which shows blood with coagulating agents or anti- anticoagulating agents stored in a syringe 114 that is injected into a fistula FIS to permit 10 its coagulation therein.
Reference is now being made to Figs. 2A-2B, which are flow diagrams exemplifying different embodiments of a method according to an aspect of the present disclosure. The method being exemplified in Fig. 2A includes withdrawing whole blood from a subject 250 having an abnormal hollowed space to be treated, e.g. a fistula or an 15 anal fistula. The method further includes mixing the withdrawn blood with one or more coagulation agents or anti-anticoagulation agents 252. Then, the method includes introducing the blood and coagulation agent mixture into the abnormal hollowed space 254. This is performed while the blood is still in a flowable form, namely prior to its complete coagulation. While the blood is in the hollowed space, the method includes 20 permitting the blood to coagulate in the abnormal hollowed space 256, thereby forming a blood clot withing the abnormal hollowed space.
Reference is now being made to Fig. 2B, which differs from Fig. 2A by including after withdrawing whole blood from the subject 250 mixing the blood with one or more anti coagulation agents, thus inhibiting the natural clotting process of the blood and 25 allowing to controllably induce the clotting process thereof at a desired timing.
It is to be noted that in the instance it is required to seal one or more openings of the abnormal hollowed space, the method further includes sealing one or more of the openings to create a sinus into which the clotting blood is introduced.
