Abstract: Sheath assembly for the insertion of a cord-shaped element, comprising an introducer sheath, and an auxiliary sheath for insertion into the introducer sheath together with the cord-shaped element. In some examples, the auxiliary sheath has a housing configured to detachably couple to the introducer sheath housing, and to detachably fasten the cord-shaped element with respect to the auxiliary sheath housing.

Abstract: The application relates to a catheter device with a distal bearing for bearing a distal end of a drive shaft. The distal bearing comprises a heat conducting part for enabling heat transfer away from the distal bearing and/or a spiral sleeve for receiving the distant end of the drive shaft.

Abstract: The present invention relates to a pump, in particular a blood pump having a proximal and a distal end and a pump housing arranged therebetween, a driveshaft arranged in an interior of the pump housing along the longitudinal direction, a conveying element arranged on the driveshaft, and a cannula. Here, the pump housing, the shaft arrangement and the conveying element are coordinated with one another in such a way that these guarantee the best possible efficiency and longevity of the pump.

Abstract: An intravascular blood pump comprises a catheter, a rotor, a housing in which the rotor is housed and a flexible drive shaft extending through the catheter and rotatably supported in a proximal bearing located proximally of the rotor. The proximal bearing comprises a bearing sleeve and an outer bearing ring. The bearing sleeve comprises a proximal portion located proximally of the outer bearing ring, the proximal portion of the bearing sleeve forming an axial bearing with a proximal surface of the outer bearing ring. The bearing sleeve further comprises a distal portion extending from the proximal portion of the bearing sleeve distally into the outer bearing ring, wherein the distal portion of the bearing sleeve forms a radial bearing with the outer bearing ring.

Abstract: An intravascular blood pump (1) comprises a catheter (5), a rotor (10), a housing (11) in which the rotor (10) is housed and a flexible drive shaft (12) extending through the catheter (5) and connected to the rotor. The drive shaft (12) comprises at least one outer layer (28) and at least one inner layer (29). The drive shaft (12) is rotatably supported in a proximal bearing (13) located proximally of the rotor (10). The outer layer (28) of the drive shaft (12) is absent or thinned at a location where the drive shaft (12) is supported in the proximal bearing (13).

Abstract: The invention relates to a catheter device, comprising a drive shaft extending from a driving region of the catheter device to a distal end region of the catheter device, a rotor which is attached to the drive shaft in the distal end region and a distal bearing for bearing a distal end of the drive shaft. The distal bearing comprises a drive shaft cover which is configured to cover a section of the drive shaft extending distally of the rotor. On a distal side of the rotor, a radially inner part of the rotor is recessed with respect to radially outer parts of the rotor to form a hollow space surrounding the drive shaft, wherein a proximal end of the drive shaft cover lies in said hollow space.

Abstract: In a sheath device for inserting a catheter into a patient's body, comprising a first sheath having a proximal end and a distal end, wherein when used as intended the distal end of the first sheath is provided for arrangement in the patient's body and the proximal end of the first sheath is provided for arrangement outside the patient's body, and wherein the first sheath comprises a tubular section and a sheath housing, which is disposed at the proximal end of the section and comprises a receiving channel for a catheter, according to the invention the tubular section is detachably held in a clamping element of the sheath housing in a non-positive manner so as to be able to easily shorten the tubular section.

Abstract: Sheath assembly for the insertion of a cord-shaped element (32, 105), comprising an introducer sheath (101) and an auxiliary sheath (104) for insertion into the introducer sheath (101) together with the cord-shaped element (32, 105), with first fastening means (106) for detachably fastening the auxiliary sheath to the introducer sheath, and with second fastening means (107) for detachably fastening the cord-shaped element to the auxiliary sheath, wherein the introducer sheath (101) has a first sheath housing (13, 114) and a distal tubular section (11, 41 a) that terminates in the first sheath housing, and a first flushing device (108), wherein the auxiliary sheath (104) has a second sheath inner chamber (111), a distal, tubular part (112) and a second flushing device (109).

Abstract: A sheath device for inserting a catheter into a patient's body is described. The device has a first sheath with a proximal end and a distal end. When the device is used as intended, the distal end of the first sheath is provided for arrangement in the patient's body and the proximal end of the first sheath is provided for arrangement outside the patient's body. The first sheath comprises a tubular section and a sheath housing, which is disposed at the proximal end of the section and has a receiving channel for a strand-shaped body. The device solves the problem of reliably fixing a second sheath or a catheter with respect to the first sheath by providing a clamping element on the receiving channel for fixing a strand-shaped body in the receiving channel by way of clamping.
