A method for producing a storable molded body made of bacterial cellulose and a molded body produced according to the method. A preferred method includes providing a molded body made of bacterial cellulose. Optionally, mechanically pressing the entire molded body or parts of the molded body at temperatures in the range of 10&#xb0; C. to 100&#xb0; C. and pressures in the range of 0.01 to 1 MPa for a pressing time of 10-200 min. Treating the molded body with a solution of 20% by weight to 50% by weight of glycerol and 50% by weight to 80% by weight of a C1-C3-alcohol/water mixture. Drying the treated molded body.

Method for producing a storable molded body made of bacterial cellulose

A heart valve implant comprising a supporting stent, a heart valve element, and a skirt. The skirt includes or is formed of at least one molded body, wherein the molded body is made of dried treated bacterial cellulose that has a swelling capacity that is greater than untreated bacterial cellulose of the same type.

Sealing structure for heart valve implants

A heart valve prosthesis (), including: a stent framework (), which can be transferred from a collapsed state into an expanded state, in which the stent framework () extends along an axis (A'), wherein the stent framework () has a plurality of struts (), which form a plurality of cells () connected to one another; and a heart valve (), which is fixed to the stent framework (). In accordance with the invention, the thickness (d&#x2032;) of the struts varies in the peripheral direction (U) of the expanded stent framework ().

Heart valve prosthesis

A device for closing the left atrial appendage. The device has a flexible and elongate pulling element fixed to a flexible material layer connected fixed to a self-expanding stent. The closure implant can be drawn back into the lumen of a catheter by the pulling element, and in so doing the stent framework can be transferred into a compressed state. The device enables a monitored and controllable release of the closure implant.

The invention relates to a medical sensor system () for detecting a feature () in a human or animal body (), including a signal pick-up unit (), which can be implanted in the animal and/or human body (), and a signal processing unit (), which is spatially separated from the signal pick-up unit () and which includes a transmitter () and a receiver (). The transmitter () emits an alternating magnetic field () to act on the signal pick-up unit (), and the receiver () receives a response signal () of the signal pick-up unit (), which is generated by the magnetic interaction of the alternating magnetic field () with the signal pick-up unit ().

Medical sensor system for detecting a feature in a body

The present invention refers to an implant with a surface layer having a topographic modification. The topographic modification includes a line pattern with ridge and groove widths of 0.9 to 1.1 &#x3bc;m and a ridge height of more than 0.9 &#x3bc;m.
