The invention relates to a method for filling an inflatable catheter balloon of a device for transanally introducing an infusion into the rectum or colon of a patient by means of a filling device, wherein a fill volume or a filling pressure prevailing in the catheter balloon is increased in two or more steps until there occurs a gradual, user-controllable, pneumatically initiated expansion of portions of the bowel wall, thus triggering a coordinated defecation reflex, wherein the timing and intensity of the triggering stimulus can be determined to the greatest possible extent by the user.

The present invention provides a system, a method, devices and a computer implemented with a method for the monitoring and the control of a subject's organ perfusion. The present invention further provides for the use of a system, a method, devices and a computer implemented with a method for the monitoring and the control of a subject's organ perfusion.

An anorectal expulsion device includes a balloon having a wall that extends between proximal and distal ends of the balloon and defines a balloon interior. The balloon interior contains a self-expanding, low compression-set material (e.g., open cell foam). The device also includes a catheter that extends through the proximal end of the balloon and at least a portion of the balloon interior. An interior of the catheter is in fluid communication with the balloon interior. The device also includes a termination component (e.g., a cap or a valve) coupled to the catheter at a position along the catheter that is outside of and proximal to the proximal end of the balloon (e.g., at the proximal end of the catheter). The physical configuration of the termination component is adjustable, and controls whether the balloon interior is in fluid communication with the external environment.

Apparatus comprising: a flexible sleeve adapted to be slid over the exterior of an endoscope, wherein the endoscope comprises a proximal end and a distal end, and a handle disposed at the proximal end of the endoscope, and wherein the sleeve comprises a proximal end, a distal end and a sleeve lumen extending therebetween, and further wherein the sleeve is configured to be slid over the exterior of the endoscope so as to substantially cover the exterior of the endoscope from a point adjacent to the distal end of the endoscope to a point adjacent to the handle of the endoscope; a balloon secured to the distal end of the sleeve; an inflation/deflation tube carried by the sleeve and in fluid communication with an interior of the balloon; and a pair of push tubes mounted to the sleeve.

A catheter comprising an elongated member having a distal end and a proximal end. The proximal end defines a drainage inlet extending from an external wall of the elongated member into the elongated member. The elongated member defines a first lumen that connects the drainage inlet with a drainage outlet defined by the distal end. The catheter also includes an inflatable retention balloon defined by the external wall of the elongated member and located between the drainage inlet and the drainage outlet. The catheter further includes a fluid inlet valve that protrudes from the elongated member and defines a second lumen that extends from the fluid inlet valve through the elongated member and to the inflatable retention balloon. The catheter additionally includes a secondary balloon that protrudes from the elongated member, the elongated member defining a third lumen that extends from the inflatable retention balloon to the secondary balloon.

A device that can be placed within or near the cranial vault that fluctuates in size in response to changes in CSF pressure is disclosed. The device diminishes in size when CSF pressures rise and increases in size as CSF pressures diminish. The device has the effect of reducing the flow of CSF occurring in the foramen magnum and provides an alternative to craniovertebral decompression in Chiari I patients. The device may have applications in other neurologic illnesses associated with abnormal CSF flow, such as Idiopathic Syringomyelia, Normal Pressure Hydrocephalus, and CSF dural leaks.

Disclosed is an endo-urethral catheter for a male subject. The catheter includes a tube and two balloons. The tube includes a lumen extending there along, an opening(s) on a tube distal section, and a valve positioned in the lumen. A first balloon is disposed about the tube distal section proximally to the opening(s). A second balloon is positioned proximally to the first balloon and distally to the valve. The catheter is configured to be deployed in the urinary system such that the first balloon is positioned in the bladder neck, and the second balloon is positioned adjacently and proximally to the urinary sphincter, thereby anchoring the catheter. The valve is configured to be controllably opened and shut, such as to respectively fluidly couple and decouple the bladder to the proximal end of the tube, thereby allowing the subject to controllably expel urine.

The catheter additionally includes a secondary balloon that protrudes from the elongated member, the elongated member defining a third lumen that extends from the inflatable retention balloon to the secondary balloon.

A port-a-cath needle adapted for determining the position of the needle prior to dispensing medical treatments is disclosed. Disclosed embodiments of the port-a-cath needle comprises a cannula, a hollow needle, and an inflatable balloon. The balloon is disposed at the distal end of the port-a-cath needle such that when the needle is inserted into a patient, the balloon may be inflated and the resistance pressure used to determine if the needle is inserted into the port chamber or a port-a-cath device or is surrounded by soft tissue. In certain embodiments, the balloon may be maintained in the inflated configuration in order to help retain the port-a-cath needle within the port chamber while treatment is delivered to the patient.
