A dual-tube removal device for treating obstipation of animals is provided. The first tube, or lubricant conduit, selectively channels lubricant or enema solution through dispersal ports provided near the distal end of the lubricant conduit. The second tube, or pilot tube, aids is selectively inflating an inflatable cuff adjacent the same distal end. In the inflated condition, with the infusion of lubricant and or enema solution and after guiding the distal end past the fecal blockage, a user may urge the fecal blockage out of the colon of the animal.

Ablation systems of the present disclosure facilitate the safe formation of wide and deep lesions. For example, ablation systems of the present disclosure can allow for the flow of irrigation fluid and blood through an expandable ablation electrode, resulting in efficient and effective cooling of the ablation electrode as the ablation electrode delivers energy at a treatment site of the patient. Additionally, or alternatively, ablation systems of the present disclosure can include a deformable ablation electrode and a plurality of sensors that, in cooperation, sense the deformation of the ablation electrode, to provide a robust indication of the extent and direction of contact between the ablation electrode and tissue at a treatment site.

A trans anal irrigation device that can be used on a bed. The device includes a rectal catheter connected to an irrigation fluid supply. A waste collection bag is also connected to the catheter. The catheter may be insertable in a seat attached to a fluid supply line. A valve in one of the catheter or seat selectably allows or prevents fluid communication between the catheter and a waste collection bag. The catheter may include an inflationless cuff made of a flexible material that permits it to be inserted in the rectum to prevent leakage around the exterior of the catheter.

A system for anal and/or stomal irrigation comprises a reservoir (102) for an irrigating liquid, a catheter (100) comprising a catheter tip for insertion into the rectum or stoma of a user and for expelling of the irrigating liquid from the catheter tip, and a tubing system (121) providing a conduit for the irrigating liquid between the reservoir and the catheter tip. A pump (101) is provided to pump the irrigating liquid from the reservoir to the catheter tip, and a control system (103) controls a flow condition, such as the amount of liquid expelled at the catheter tip. A sensor (153) determines a measure of pressure in at least one first predetermined position in the tubing system and/or the catheter during operation of the pump, on the basis of which the flow condition is estimated. The control system is configured to control the pumping operation of the pump in response to the measure of pressure.

The end of the elongated tubular element of the appliance that is designed to be inserted into a body cavity is formed entirely of soft, compliant material. That end carries an inflatable balloon made of non-expandable material, formed in the fully inflated shape, to prevent overexpansion. The balloon is inflated to a predetermined low pressure level to prevent pressure necrosis in the adjacent tissue. A method and apparatus for introducing the soft end of the appliance into the body cavity are also provided. The introducer apparatus includes rigid core surrounded by a soft, compliant sleeve. The sleeve extends beyond the rigid core to form an invertable section. The soft end of the appliance is situated adjacent the apparatus, the balloon is wrapped around the apparatus, and the sleeve section is inverted over the appliance, compressing the balloon and forming a soft, rounded insertion tip. The unit is then introduced into the body cavity. After the appliance is separated from the apparatus, the apparatus is withdrawn.

A trans anal irrigation device that can be used on a bed. The device includes a rectal catheter connected to an irrigation fluid supply. A waste collection bag is also connected to the catheter. The catheter may be insertable in a seat attached to a fluid supply line. A valve in one of the catheter or seat selectably allows or prevents fluid communication between the catheter and a waste collection bag. The catheter may include an inflationless cuff made of a flexible material that permits it to be inserted in the rectum to prevent leakage around the exterior of the catheter.

A method and apparatus for cleansing the interior surfaces of body cavities employs a balloon catheter adopted to be inserted into a cavity through its ostium with the balloon in collapsed condition. An input flow tube for a cleansing and/or medicating fluid passes through a central passage in the balloon. When the balloon is inflated to establish a narrow passage between the balloon and the cavity walls, a pressurized flow of the fluid is pumped out the distal end of the input flow tube through the passage, parallel to the cavity walls, where it scours the inner wall of the cavity, removing debris as it flows out of the ostium. The fluid flow is urged toward a turbulent condition by attachments to the outer wall of the balloon.

The body has a fluid inlet port for receiving pressurized fluid and a fluid outlet port connected to the retention balloon. A first passage connects the fluid inlet port and the fluid outlet port, A second passage in the body is connected to the balloon fluid return path and is at the pressure of the retention balloon. A valve prevents fluid flow through the first passage when actuated. The valve includes a pressure-responsive member movable to a position to obstruct fluid flow in response to fluid pressure in the second passage exceeding the predetermined level. Flexible means such as a membrane defines a normally open portion of the first fluid passage, which is closed by the moveable means bearing on the membrane when pressure exceeding the predetermined level actuates the valve.

A medical syringe with at least three ports, in conjunction with a urinary catheter, can be used for closed manual irrigation of a bladder. The three syringe ports are located on a port body. Each of the three syringe ports can be manually selected by rotating a barrel that has a closed end located inside the cup-shaped port body. Rotation of the barrel inside the port body occurs about an axis that is aligned with the central axis of the hollow cylindrical barrel. The system is configured to selectively fill the syringe with an input fluid, irrigate the bladder by passing fluid into and out of the urinary catheter, and drain bladder contents into a drainage vessel without ever needing to remove the syringe from the catheter.

Devices and methods for providing an internal balloon sheath are disclosed. One device includes a sheath for insertion through an arteriotomy of a patient. The sheath comprises a tubular sheath body having a longitudinal axis, an open proximal end, an open distal end, an outer surface and an inner surface, the inner surface defining a lumen between the proximal and distal ends for passage of a catheter device. The sheath also comprises an inflatable balloon disposed within the lumen. The inflatable balloon is configured to occupy a longitudinal space in the lumen between the inner surface of the sheath body and the catheter device when the catheter device is disposed within the sheath and the balloon is inflated, and fluidically seal the lumen.
