Abstract
Abstract An inflatable balloon-like bulb attached to the end of a checkvalved catheter tube, removably attachable to an inflating bulb, with a stop means slidable along the catheter tube, the arrangement being such that when the balloon is deflated on the end of the catheter tube, it may be inserted through the urethra into the bladder, then inflated by the bulb, and held in that position by the sliding stop pushed up against the urethral outlet walls to hold the inflated balloon in sealing relationship. The device also may be used in like manner to seal the rectum.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
172 words
A surgical device of the kind described, comprising: a tube insertable through an external opening of the body communicating by a passage to an internal cavity, an inflatable balloon-like member sealed over the end of the tube with its interior communicating with the axial passage of the tube; releasable means to prevent deflation of the balloon-like member, and stop means slidable along the tube, the stop means having releasable means self-contained in the stop means and engageable at any point along the tube to hold to the tube, to restrain movement of the stop means in the direction away from the balloon-like member, the stop means having smooth surfaces whereby it is comfortable to the user, whereby when the tube and member are inserted through the passage and the balloon-like member is inflated in the cavity, the balloon-like member may be drawn into sealing relation about the entrance of the passage and held there when the stop means is slid along the tube and engaged against the external walls of the passage.
Claim 2
Dependent Claim
172 words
A surgical device of the kind described, comprising: a tube insertable through an external opening of the body communicating by a passage to an internal cavity, an inflatable balloon-like member sealed over the end of the tube with its interior communicating with the axial passage of the tube; releasable means to prevent deflation of the balloon-like member, and stop means slidable along the tube, the stop means having releasable means self-contained in the stop means and engageable at any point along the tube to hold to the tube, to restrain movement of the stop means in the direction away from the balloon-like member, the stop means having smooth surfaces whereby it is comfortable to the user, whereby when the tube and member are inserted through the passage and the balloon-like member is inflated in the cavity, the balloon-like member may be drawn into sealing relation about the entrance of the passage and held there when the stop means is slid along the tube and engaged against the external walls of the passage.
Claim 3
Dependent Claim
25 words
In the surgical device of claim 1: a check valve secured to the tube to constitute the means to prevent deflation of the balloon-like member.
Claim 4
Dependent Claim
18 words
In the device of claim 2: means for removably attaching an inflater to the end of the tube.
Claim 5
Dependent Claim
32 words
In the device of claim 1: the stop means comprising a clip that is made to engage more tightly onto the tube by forces acting in the direction away from the balloon.
Claim 6
Dependent Claim
31 words
In the device of claim 1: the stop means comprising a clip that is relatively narrow and elongated so as to span the body opening and fit within the vestibUle thereof.
Claim 7
Dependent Claim
42 words
In the device of claim 5: the stop being constructed of elastic material having a passage therethrough to receive the tube, the passage having some rigid teeth engageable with the tube and separable therefrom by stretching the elastic of the stop means.
