A medical device is disclosed capable of reducing risk factors of an anastomotic leakage after a surgical operation is performed. The medical device includes an adhesion promotion sheet configured to include an adhesion promotion portion promoting adhesion of biological tissues and a frame portion provided outside the adhesion promotion portion in a plane direction and a pulling unit connected to the adhesion promotion sheet and configured to deform a second region so as to cover at least a portion of an outer peripheral surface of a biological organ to be joined with a pulling operation.

Medical device

To reduce the risk of a ruptured suture after a surgery or the like, a medical apparatus includes a biodegradable sheet in which a plurality of through-holes are formed, a value of a ratio (D/P) of a hole diameter D to a pitch P of the through-hole is in a range of 0.25 or more and less than 40. Such a medical apparatus is useful as an adhesion promoting device for promoting adhesion of biological tissue.

Medical apparatus and adhesion promoting device using same

Provided is a treatment method that reduces risk factors contributing to anastomotic leakage by using a medical device. The treatment method includes placing a medical device including a sheet-like main body portion for promoting adhesion between biological tissues between one joint target site and another joint target site of a biological organ to be joined, and joining the one joint target site and the other joint target site to each other in a state where at least a portion of the main body portion is interposed between the one joint target site and the other joint target site.

Treatment method for joining biological organs

A medical tube(drain tube) includes a main shaft tube, a flow path opening/closing mechanism, and a branch tube. The main shaft tubeinternally has a main shaft side distal openingand a main shaft lumen. The flow path opening/closing mechanismbrings the main shaft lumeninto a communicating state by applying pressure smaller than predetermined pressure, and brings the main shaft lumeninto a blocked state by applying pressure equal to or greater than the predetermined pressure. The branch tubepromotes a pancreatic juice pj to flow into a branch lumen, based on the applied pressure which is equal to or greater than the predetermined pressure.

Medical tube

A digestive tract device that can reduce an indwelling-induced burden on the living body includes: a tubular portion that includes a through hole; a holding portion that is provided on a proximal end side of the tubular portion, and holds the tubular portion in the living body; and support portions and which are provided in the holding portion, and are in contact with a plurality of sites of the digestive organ of the living body, and support the holding portion in such a way that the holding portion can move in at least one direction of a circumferential direction and a longitudinal direction of the tubular portion.

Digestive tract device

A liner support frame is configured to be positioned in a gastrointestinal tract of a human and to support a liner which inhibits nutrient absorption and anchor the liner in place in the gastrointestinal tract, the liner support frame includes a plurality of frame members connected to one another so that the liner support frame possesses a plurality of openings. The liner support frame includes a plurality of frame portions arranged axially and possessing different tapers.

Bypass device, support frame for bypass device, and method

A digestive tract device is configured to reduce the burden on a living body associated with the adjustment of the length of a tubular portion retained inside the living body and simplify a retention operation after introducing the digestive tract device into the living body. The digestive tract device includes a tubular portion provided with a main body having a through hole extending in the longitudinal direction and a tip opening continuous with the through hole and a folded-back portion formed by folding back the main body in the longitudinal direction, a holding unit which holds the folded-back portion in a folded-back state with the tip opening open, and a retention unit which is provided on the base end side of the tubular portion and retains the tubular portion inside a living body.
