The disclosure relates to the area of medicine and surgery, in particular it pertains to a drainage catheter (100) that comprises a high capacity drain comprising a radiological guide (110a) with a suction mesh (110b), a safety control opening/closing system (160), an internal pneumatic clamping system (140) and/or an external adhesive skin protection system (150). A reservoir for the administration of local anesthetics and antibiotics may be additionally provided. The disclosed catheter system optimizes flow surface, facilitates procedures for handling and removal of drainage, reduces the risk of occlusions, pain, injuries and infections of the surrounding skin and maintains sufficient structural strength to prevent collapses, among others.

The present invention relates to a dental suction device for managing fluid in a patient's mouth during a dental procedure. The dental suction device comprises a pliable tube having a first end for connection to a vacuum source and a second end that can be looped to form a suction end for positioning in a patient's mouth. The loop is adjustably secured by a pair of retaining collars positioned a certain distance apart from each other along the second end of the tube and connected together by a tie. The loop, adjusted to accommodate the shape of the patient's mouth, is secured around the terminal end of a row of teeth in the patient's mouth. In this way, the dental suction device can be maintained and operated in the patient's mouth during a dental procedure.

The present disclosure is directed to a medical device. Systems and methods are provided for utilizing a laser to break a kidney stones into smaller fragments and/or dust, and removing particles, stone fragments and/or stone dust from a patient. The medical device may include a delivery device including a tube, and an elongate member having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end, wherein the elongate member is configured to move axially relative to the tube and apply suction through the distal end.

The present disclosure relates to a biliary drainage device for negative pressure-retrogradeinstallation of percutaneous transhepatic biliary drainage, and the biliary drainage device for negative pressure-retrogradeinstallation of percutaneous transhepatic biliary drainage (NR-PTBD) according to the present disclosure is a biliary drainage device for negative pressure-retrogradeinstallation of percutaneous transhepatic biliary drainage (NR-PTBD) being performed in a pancreaticoduodenectomy process, the biliary drainage device including a flexible tube having a suction port formed at one side end and mounted on an afferent loop in order to suck bile; and a guide member installed at the other end of the tube so that the tube inserted through a cut part of a biliary tract can penetrate a liver tissue.

The disclosed system includes a probe for mechanically cutting tissue Other components of the system include a luminally protective sheath, a microscopic end cauterizing probe, a surgical console, an identification-sensitive self-sealed cassette, and a plurality of flexible tubing lines with pinch valves thereon.

In some examples, an aspiration catheter system includes an outer catheter and an inner catheter configured to be positioned within the outer catheter lumen, and an alignment element. The outer catheter defines an outer catheter lumen and an outer catheter distal opening. The inner catheter defines an inner catheter lumen, an inner catheter distal opening, and a plurality of sidewall openings proximal to the inner catheter distal opening. The alignment element is configured to indicate a predetermined position of the inner catheter relative to the outer catheter when the inner catheter is received within the outer catheter distal opening. When the inner catheter is at the predetermined position, at least one sidewall opening of the plurality of sidewall openings remains positioned within the outer catheter lumen and at least one other sidewall opening of the plurality of sidewall openings is positioned distal to the outer catheter distal opening.

Disclosed is a pericardiocentesis needle component (10), comprising a guide wire (13) and a puncture needle (12). The guide wire (13) extends into and through the puncture needle (12), and the guide wire (13) comprises a bent section (32) at the distal end and a straight section at the proximal end. The bent section (32) at the distal end is formed by bending the guide wire (13), and the end of the bent section is a pointed-shape structure. The guide wire (13) is made of a highly elastic material. The pointed end rotates at least 90 degrees within a range of no more than 3 mm starting from the pointed end at the bent section (32) of the guide wire. The pericardiocentesis needle component (10) of the present invention is less likely to damage a heart during a pericardiocentesis procedure.

A wound drainage and hemostasis promoting medical device (1) are disclosed. A balloon (15) is temporary inflated and arranged outside a sheath (10), in contact with tissue surrounding a wound cavity for hemostasis promotion. The drainage device comprises a fluid communication channel for wound exudate from wound. The balloon is deflated and retracted into said sheath for removal from said wound cavity. Thus the medical device is percutaneously retractable from said confined wound.

Assemblies, systems, and methods convey fluid from an internal wound site or body cavity by applying negative pressure from a source outside the internal wound site or body cavity through a wound drain assembly that is placed directly inside the internal wound site or body cavity.

A chest drainage system including a collection device configured to receive fluid from the pleural cavity of a patient. A sensor is included to detect a pressure differential in the fluid. A display is configured to display a trend in occurrences of changes in pressure of the fluid over time in predetermined time increments based on a number of detections of pressure differentials that exceed a predetermined pressure differential during each of the predetermined time increments. The trend is correlative to the percentage of time that the patient is deemed to have an air leak in the pleural cavity in the predetermined time increments. The trend is derived from a ratio of the quantity of respiratory cycles of the patient for which the predetermined pressure differential is detected (QRC.sub.leak) in the predetermined time increments to the total quantity of respiratory cycles of the patient in respective predetermined time increments (QRC.sub.total).
