A corresponding device is also described.
The present invention relates to a catheter device (1) for implanting a medical implant (100), particularly a prosthetic heart valve such as a prosthetic aortic heart valve, wherein the device (1) comprising a handle (70) for controlling/steering multiple sheaths 10, 20, 60 of the catheter device (1).
A balloon catheter system includes a balloon extending in an axial direction. A stent is crimped onto an outer surface of the balloon. A catheter is connected to the balloon and includes a lumen in fluid communication with a balloon interior of the balloon. At least one sensor associated with the balloon measures expansion of the balloon in a radial direction (R). A processing unit receives a signal from the at least one sensor and is connected to terminate filling of the balloon interior with a fluid medium (M) and/or to prompt a display device to output a display if the signal reaches a threshold value above a predefined reference value, the signal being indicative of a current diameter (D) of the balloon in the radial direction (R), the reference value corresponding to a balloon diameter upon contact of a proximal and/or distal balloon end with a vessel wall, and the threshold value exceeding the reference value by 5% to 20%.
A catheter includes a catheter shaft with an outer surface extending from a proximal end portion to a distal end portion of the catheter shaft. A connector is connected to the proximal end portion of the catheter shaft. A material surrounds the proximal end portion. A printed circuit board is embedded in the material. The printed circuit board has a conductor track. At least one electrical conductor is printed on the outer surface of the catheter shaft. The at least one electrical conductor contacts the conductor track so that the at least one electrical conductor and the at least one conductor track are electrically conductively connected.
A processing system including a processing unit is configured to be connected to a catheter in a releasable fashion via a connecter portion of a housing. The processing unit is configured to exchange data with a component of the catheter and at least one of a database, a computer network, and a computer device. The processing unit includes an integrated circuit for processing the data.
An implant includes a tubular discontinuous structure formed of a plurality of webs that at least partially extend in a longitudinal direction. The plurality of webs includes at least one joint element having a main web substantially extending in the longitudinal direction. There is a continuous gap in the main web. At least one bridge web is arranged next to the main web in a circumferential direction (U) and connected to the main web in the longitudinal direction (A) in front of and behind the gap.
A61F 2/915 - Stents in a form characterised by wire-like elementsStents in a form characterised by a net-like or mesh-like structure characterised by a net-like or mesh-like structure made from perforated sheets or tubes, e.g. perforated by laser cuts or etched holes with bands having a meander structure, adjacent bands being connected to each other
A61F 2/962 - Instruments specially adapted for placement or removal of stents or stent-grafts having an outer sleeve
The present invention relates to a method for producing a swellable body (10) comprising bacterial cellulose, wherein the method comprises the steps of: providing a body (10) made of bacterial cellulose, cleaning the body (10) using at least one liquid medium, and freeze-drying the body (10).
A method for connecting an X-ray marker to a base body of an implant is provided. The based body includes a receptacle for receiving an X-ray marker. A flexible film and an X-ray marker are arranged so that at least a section of the film is located between the receptacle and the X-ray marker. The X-ray marker is pressed into the receptacle while interposing the film so that the X-ray marker is plastically deformed and, together with the film, is fixed in a force-fit manner in the receptacle. The film prevents contact between the X-ray marker and the base body.
