摘要:
A tubular implanted appliance (103) is provided with a fr amework part (2) and a tubular coating film part (1) forming a partitio n wall, the tubular implanted appliance (103) being configured so as to be able to expand and retract in the axial direction of the coating film part. The framework part has a plurality of annular linear members (2 1) extending along the circumferential direction of the coating film part while bending in the axial direction of the coating film part. The plur ality of linear members are disposed in a row in the axial direction of the coating film part, and are attached and fixed to the surface of the coating film part at intermediate portions (21c) between end parts in t he axial direction of the linear members.

The present invention eliminates the need for highly accurate alignment with a branched tubular tissue when implanting a stent graft. A stent graft 30 comprises: a framework section 31; and a tubular graft section 40. A side surface opening 42 that passes through to the lumen of the graft section is provided in one section of a tube wall 41 of the graft section. In the framework section, among the six frame bodies, the frame bodies 34, 35 that are provided facing the side surface opening section have a first frame body structure section Q that is present in the tube wall along the entire circumference, and a second frame body structure section P that is present in the tube wall in a partial region 41A, which excludes the side surface opening section in the circumferential direction of the tube wall.

It is an object of the present invention to provide a blood purifying apparatus capable of avoiding burdensome apparatus arrangement and reducing a burden on an operator while ensuring patient safety. The present invention provides a blood purifying apparatus (80) including a blood pump (81) for feeding blood on an arterial line toward a blood purifier, a dialysate pump (82) for feeding dialysate on a dialysate line toward a blood purifier, a waste fluid pump (83) for feeding out waste fluid in a waste fluid line, a first pump (84) for feeding a substitution fluid in a first line toward a venous line, a second pump (85) for feeding a replacement fluid in a second line toward the venous line, and a controller (90) configured to control driving of these pumps. The controller (90) controls the flow rate of the first pump (84) and the flow rate of the second pump (85) in an interlocking manner.
摘要:
A stent (1) having a generally tubular body formed of annular units with a plurality of cells and extendable in a radial direction from the inside thereof, wherein the annular units (4) are formed by vertically connecting the plurality of cells (6) and a plurality of the connected cells are arranged so as to surround the center axis (C1) of the stent forming the tubular body, the annular unit is arranged in the axial direction of the stent, the annular units are connected to each other at least at one position through a connection part (5), the connection part is formed of a curved part (8) having two or more arcs and a generally straight part (7) continued to the curved part, the cells are arranged by three to eight units per 10 mm in length of the stent, and the ratio of the axial length (5L) of the connection part in stent axial direction to that (6L) of the cells in stent axial direction is set to 100 to 50 to 100, whereby a high flexibility and a radiation support force can be sufficiently assured and a vasodilating capability can be increased to suppress a fore-shortening and a flare event.
摘要:
Provided are a stent graft indwelling device, which facilitates the adjustment of release or indwelling of a stent graft from or in a blood vessel by attaching a plurality of holding rings of wire when the stent graft is caused to indwell in the blood vessel, a stent graft and a fixed chip. The stent graft hence comprises adjusting means for adjusting the insertion angle and/or indwelling position of a stent graft (60) when the stent graft (6) is released from a sheath (30) and caused to be indwell, and the adjusting means for adjusting the insertion angle and/or indwelling position of a stent graft (60) includes a fixed chip (20) containing a contrast medium and/or a holding ring (69A) attached to a rearmost tubular unit (61) of the stent graft (60).
摘要:
In a microcatheter (1), the shaft tube (2) thereof is sectioned into a proximal zone (3), an intermediate zone (4) and a distal zone (5) from said connector to the forward end thereof, each being formed of a multilayered tube, consisting of three types of multilayered tubes different in hardness, an inner layer (8) extending along all the zones from the proximal zone (3) to the distal zone (5) of said shaft tube (2), and a reinforcing material (7) being fitted to the outer circumference of said inner layer (8), a first outer layer (11) extending along all the zones from the proximal zone (3) to the distal zone (5) of said shaft tube (2) so as to coat, and adhere to, said inner layer (8) and said reinforcing material (7), to form a base layer structure composed of the inner layer (8)/reinforcing material (7)/first outer layer (11), a third outer layer (13) coating the first outer layer (11) of said base layer structure in the proximal zone (3), a second outer layer (12) coating the first outer layer (11) of said base layer structure in the intermediate zone (4), the microcatheter hence being improved in pressure resistance and improved in antikinking property, which enables superselective approaching a minute blood vessel.
摘要:
To provide a personal identification system for collating an article requiring personal identification with a person using the article, the system has a personal identification data reader for reading the image of a characteristic portion of a human body capable of identifying a person such as his fingerprint and digitizing the image as data. Moreover, the system has a label printer for printing said personal identification data on a label as two-dimensional data codes and the personal identification data printed on the label is read by a label data reader serving as a two-dimensional data code reader. The personal identification data is collated with the personal identification data read by the personal identification data reader and acceptance or rejection of the collation result is decided. These operation histories are recorded and preserved in a hard disk.
摘要:
A process for producing a medical device having a branch includes the steps of: welding a bottom of the tubular member on a mounting surface of a constituent material of a main tube extruded under elevated temperature, welding firmly the bottom of the tubular member to the mounting surface of the main tube while aspirating the constituent material of the main tube from above the tubular member, forming a hole in the mounting surface of the main tube so as to communicate an interior of the tubular member with an interior of the main tube, and cutting the main tube, whereby assembling the medical device having the branch.
