20080200759 | MEDICAL APPARATUS - In a case where a balloon is broken and a body fluid reversely flows into a feed/discharge tube during a suction operation of a balloon control apparatus, a pump is stopped by operation-canceling section after passing of a preset predetermined time, and the suction operation of sucking the fluid into a bottle is canceled. Thereby, the amount of recovered liquid in the bottle is limited within a predetermined capacity. Thus, even in the case where the body fluid reversely flows into the feed/discharge tube, the body fluid does not overflow from the bottle, and the body liquid can properly recovered in the bottle. | 08-21-2008 |

20150297061 | INSPECTION POSITIONING PROSTATIC CAPSULE EXPANSION CATHETER - An inspection positioning prostatic capsule expansion catheter includes a catheter main body. The catheter main body is internally provided with a catheterization cavity, a rinse cavity, a front bag cavity, and a rear bag cavity. The four cavities are each provided with a front-end opening. At the rear of the front-end openings of the catheterization cavity and the rinse cavity is the front bag cavity. At the rear of the front bag cavity is the rear bag cavity arranged in parallel. The catheter main body at the tail of the rear bag cavity is provided with a miniature visual probe. The miniature visual probe is mounted on a semi-circular protrusion at the tail of the rear bag cavity. | 10-22-2015 |
20160051135 | 4-WAY CYSTOSCOPY CATHETER - Systems and methods of cannulating a body orifice such as a bladder are disclosed. A cystoscopy catheter can include a proximal end, a distal end having at least one exit port, and a flexible elongate tubular body therebetween; an inflatable balloon near the distal end of the catheter, the balloon transformable from an unexpanded and an expanded configuration; a first proximal port for fluid inflow; a second proximal port for fluid outflow; a third proximal port for balloon inflation, in fluid connection with the balloon; and a fourth proximal port for insertion of a diagnostic and/or therapeutic instrument such as a cystoscope therethrough, wherein the first, second, and fourth proximal ports are fluidly connected to a common central lumen extending through the elongate tubular body to the exit port on the distal end. | 02-25-2016 |
20160106301 | ATRAUMATIC ARTHROSCOPIC INSTRUMENT SHEATH AND METHOD - A removable, resilient atraumatic sheath for arthroscopic instruments. The sheath covers sharp edges on the arthroscopic instrument, particularly the distal tip of the rigid cannula, and thereby protects tissue and objects near a surgical site from accidental trauma. The sheath may be provided in the form of an inflow/outflow sheath that allows a surgeon to irrigate and drain a surgical field without the use of a separate irrigation instrument. | 04-21-2016 |

20220133136 | ACCESS DEVICE - Tissue access devices and methods of using the same are disclosed. For example, an access device is disclosed having a first sheath having a first sheath lumen, a second sheath having a second sheath lumen, and an engager. The second sheath can be deflectable into and out of the first sheath lumen. The engager can be expandable and contractible. When the engager is in an expanded configuration, a space can be between the engager and the first sheath and the second sheath can be deflectable into and out of the space. | 05-05-2022 |
