## Abstract

A medical device for providing direct port-like endoscopic access to the urinary bladder, or other orifice, of a patient and a method of utilizing and inserting the medical device. The medical device can include a hollow tube with a main channel and a separate channel, a cap with an inflation port and a hollow flexible stem fluidly connecting the inflation port and the separate channel. A method can include inserting a needle above the pubic symphysis of a mammal, threading a guide wire through the needle, removing the needle and inserting the medical device. The method can optionally include determining measuring the depth between the skin surface of the patient's suprapubic region and urinary bladder.

## Claims

### Claim 1

A medical device comprising:
a continuous hollow tube, the length sized for spanning the distance between an exterior surface of a mammal and an interior cavity of the mammal's urinary system, the hollow tube having an open proximal end and an open distal end;
a first cap having a top surface and a bottom surface, the first cap being operatively configured for securely attaching to the proximal end of the tube;
a hollow flexible stem fluidly connecting the first cap and the proximal end of the hollow tube so that liquid may pass into the bottom surface of the first cap, through the hollow flexible stem and into a separate channel within the hollow tube; and
an inflation port on the bottom surface of the cap.

### Claim 2 (depends on 1)

The medical device of claim 1 wherein the continuous hollow tube has a diameter between 10 French and 40 French and the proximal end of the hollow tube is longitudinally more rigid than the distal end.

### Claim 3 (depends on 2)

The medical device of claim 2 wherein the diameter of the continuous hollow tube is between 20 and 30 French.

### Claim 4 (depends on 2)

The medical device of claim 2 wherein the diameter of the continuous hollow tube is greater than 30 French.

### Claim 5 (depends on 2)

The medical device of claim 2 wherein the diameter of the continuous hollow tube is less than 20 French.

### Claim 6 (depends on 1)

The medical device of claim 1 wherein the first cap covers the open proximal end of the tube when securely attached to the proximal end of the tube and the bottom surface of the cap is recessed within the proximal end of the tube upon secure attachment.

### Claim 7 (depends on 1)

The medical device of claim 1 wherein the fluidly separate channel runs from the proximal end of the hollow tube toward the distal end of the hollow tube and the hollow flexible stem is permanently attached to the hollow tube below the open proximal end of the hollow tube.

### Claim 8 (depends on 1)

The medical device of claim 1 wherein the inflation port is operatively configured to receive liquid via a syringe so when the cap is not securely attached to the proximal end of the tube liquid may be injected via the inflation port and travel from the cap, through the hollow flexible stem and down the separate channel within the hollow tube.

### Claim 9 (depends on 1)

The medical device of claim 1 further comprising a second cap having top surface and a bottom surface that is operatively configured to securely attach to the proximal end of the tube, the second cap having at least one port from the top surface through to the bottom surface.

### Claim 10 (depends on 1)

The medical device of claim 1 further comprising an inflatable balloon along the exterior surface of the hollow tube and in fluid communication with the inflation port via the separate channel within the hollow tube.

### Claim 11 (depends on 1)

The medical device of claim 1 wherein the length of the continuous hollow tube is between a length between 0.8 cm and 15 cm.

### Claim 12 (depends on 1)

The medical device of claim 1 wherein the length of the continuous hollow tube is greater than 8 cm.

### Claim 13 (depends on 1)

The medical device of claim 1 wherein the length of the continuous hollow tube is less than 10 cm.

### Claim 14 (depends on 1)

The medical device of claim 1 wherein the inflation port of the device sits at least partially beneath skin of the mammal after insertion of the device and when the cap is securely attached to the proximal end of the tube.

### Claim 15 (depends on 1)

The medical device of claim 1:
wherein the continuous hollow tube has a diameter between 10 French and 40 French;
wherein the first cap covers the open proximal end of the tube when securely attached to the proximal end of the tube, the bottom surface of the cap being recessed within the proximal end of the tube upon secure attachment;
wherein the hollow flexible stem is permanently attached to the hollow tube below the open proximal end of the hollow tube and the separate channel runs from the proximal end of the hollow tube toward the distal end of the hollow tube; and
wherein the inflation port is operatively configured to receive liquid via a syringe so when the cap is not securely attached to the proximal end of the tube liquid may be injected via the inflation port and travel from the cap, through the hollow flexible stem and down the separate channel within the hollow tube.

### Claim 16 (depends on 1)

The medical device of claim 1 wherein the exterior surface of the mammal is the mammal's back and the interior cavity of the mammal's urinary system is the mammal's pelvis of its kidney.

### Claim 17 (depends on 16)

The medical device of claim 16 further comprising a one way valve located within the tube of the medical device to prevent liquid from traveling from the mammal's kidney to the external surface of the mammal's skin when the first cap is not securely attached to the proximal end of the tube.
