Abstract
Abstract Apparatus useful in surgery for holding part of a patient's body such as a limb, portion of a limb, extremity organ or tissue in a number of different positions required by a surgeon for the performance of a surgical procedure, and for establishing a sterile barrier between a surgical site and a patient's limb or body part while the limb or body part is being grasped by a such positioning apparatus.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
59 words
Apparatus for forming a sterile barrier around a body part or the like, comprising: (a) an elongated tube of sterile flexible material, gathered together into a toroidal shape; and (b) removable impervious material enclosing the toroidal shaped tube such that the body part can be passed through the tube while the tube is enclosed by the removable impervious material.
Claim 2
Dependent Claim
59 words
Apparatus for forming a sterile barrier around a body part or the like, comprising: (a) an elongated tube of sterile flexible material, gathered together into a toroidal shape; and (b) removable impervious material enclosing the toroidal shaped tube such that the body part can be passed through the tube while the tube is enclosed by the removable impervious material.
Claim 3
Dependent Claim
22 words
Apparatus as defined in claim 1 wherein the elongated tube of sterile flexible material is gathered together by rolling the elongated tube.
Claim 4
Dependent Claim
22 words
Apparatus as defined in claim 1 wherein the elongated tube of sterile flexible material is gathered together by folding the elongated tube.
Claim 5
Dependent Claim
43 words
Apparatus as defined in claim 1 wherein the elongated tube is gathered together upon a rigid tubular member such that the toroidal shape of the gathered together elongated tube is maintained while the gathered together elongated tube is located on the body part.
Claim 6
Dependent Claim
26 words
Apparatus as defined in claim 1 further including elastic means for securing the elongated tube at a selected location along the length of the body part.
Claim 7
Dependent Claim
170 words
Apparatus for establishing a sterile barrier between a surgical site and a patient's limb or body part and a positioning apparatus, while said limb or body part is connected to a supporting point by a said positioning apparatus, such that the combination of said limb or body part, said supporting point, said positioning apparatus and the patient's body form a closed annular shape, comprising: (a) an elongated tube of sterile flexible material, gathered together from both ends so as to form a double toroid, such that said double toroid can be located at any position on said limb or body part of said positioning apparatus; and (b) removable impervious material sealed around said double toroid such that said limb or body part or said positioning apparatus can be passed through said elongated tube without coming into contact with said elongated tube, and such that said impervious material can be removed and said elongated tube can be extended onto said limb or body part and said positioning apparatus in opposite directions.
Claim 8
Dependent Claim
170 words
Apparatus for establishing a sterile barrier between a surgical site and a patient's limb or body part and a positioning apparatus, while said limb or body part is connected to a supporting point by a said positioning apparatus, such that the combination of said limb or body part, said supporting point, said positioning apparatus and the patient's body form a closed annular shape, comprising: (a) an elongated tube of sterile flexible material, gathered together from both ends so as to form a double toroid, such that said double toroid can be located at any position on said limb or body part of said positioning apparatus; and (b) removable impervious material sealed around said double toroid such that said limb or body part or said positioning apparatus can be passed through said elongated tube without coming into contact with said elongated tube, and such that said impervious material can be removed and said elongated tube can be extended onto said limb or body part and said positioning apparatus in opposite directions.
Claim 9
Dependent Claim
210 words
Apparatus for establishing a sterile barrier between a surgical site and a patient's limb or body part and a positioning apparatus, while said limb or body part is connected to a supporting point by said positioning apparatus, such that the combination of said limb or body part, said supporting point, said positioning apparatus and the patient's body form a closed annular shape, comprising: (a) elongated tube of sterile flexible material, gathered together into a toroidal shape; and (b) removable impervious material sealed around said toroidal shape such that said limb or body part or said positioning apparatus can be passed through said elongated tube, and such that said impervious material can be removed and said elongated tube can be extended onto said limb or body part and said positioning apparatus after they have been connected together to form said annular shape, such that a sterile barrier is formed, and wherein said removable impervious material comprises a second elongated tube which is passed through the opening in said toroidal shape and wherein the ends of said second elongated tube are each in turn folded over the outer surface of said toroidal shape and folded back, so as to form two overlapped cuffs, and wherein said overlapped cuffs are detachably sealed together.
Claim 10
Dependent Claim
210 words
Apparatus for establishing a sterile barrier between a surgical site and a patient's limb or body part and a positioning apparatus, while said limb or body part is connected to a supporting point by said positioning apparatus, such that the combination of said limb or body part, said supporting point, said positioning apparatus and the patient's body form a closed annular shape, comprising: (a) elongated tube of sterile flexible material, gathered together into a toroidal shape; and (b) removable impervious material sealed around said toroidal shape such that said limb or body part or said positioning apparatus can be passed through said elongated tube, and such that said impervious material can be removed and said elongated tube can be extended onto said limb or body part and said positioning apparatus after they have been connected together to form said annular shape, such that a sterile barrier is formed, and wherein said removable impervious material comprises a second elongated tube which is passed through the opening in said toroidal shape and wherein the ends of said second elongated tube are each in turn folded over the outer surface of said toroidal shape and folded back, so as to form two overlapped cuffs, and wherein said overlapped cuffs are detachably sealed together.
