Abstract:
A valve for a heart valve prosthesis comprising a valve membrane composed of at least one spiral strip which, in the closed state of the valve membrane, assumes the form of an Archimedean spiral, wherein the outer edge regions of the spiral strip overlap an inner edge region of the spiral strip of a previous winding of the spiral.
Abstract:
The invention relates to a delivery system for a medical device and a method for operating a delivery system for a medical device, in particular a stent having a proximal end and a distal end, an inner shaft enclosing an inner lumen and an outer shaft surrounding the inner shaft in at least some areas and enclosing an intermediate lumen. One or more openings are provided in the inner shaft establishing a fluid connection between the inner lumen and the intermediate lumen.
Abstract:
An elastic cap for covering the distal end of a catheter having inner and outer hoses, characterized in that the cap consists essentially of an elastic material, has a cavity in which the distal end of the inner and the outer hose of a catheter can be received, and the cap has a first opening via which the cavity is accessible from the outside, wherein prior to receiving the distal end of the catheter, the first opening has a diameter which is not larger than the outer diameter of the inner hose of the catheter and wherein the first opening is elastically expandable to a diameter which corresponds to the outer diameter of the outer hose.
Abstract:
A delivery system having a release mechanism (70) for releasing an object (12), in particular, a supporting body, which is carried by the catheter (20), whereby the catheter (20) has at least one outer shaft (50) which is relatively displaceable toward the object (12) to release the object (12). The catheter (20) has a winding device (100) on its proximal end (24) which winds up a proximal section (52) of the outer shaft (50) to create a relative displacement of the outer shaft (50).
Abstract:
The invention relates to an implantable drug reservoir (10) having a cavity (28) enclosed by a sheathing (12) and arranged between a proximal end (14) and a distal end (16) for storing one or more drugs (50), having an outlet opening (24) for the drug(s) (50). The drug(s) (50) can be delivered to a delivery region (70) through a puncture device (20) at one end (16). The invention also relates to a device (100) having a drug reservoir (10).
Abstract:
The invention relates to a drug-loaded implant having a carrier body (10) and at least one drug for delivery into a delivery region. The drug is provided for chemotherapy and/or palliative treatment and can be released topically and/or regionally in a controlled manner at a predefinable rate and/or over a predefinable period of time in the intended active state of the implant.

Abstract:
The invention relates to an implantable device for local release of at least one drug at a predefined location in a natural cavity having a wall in the body of a mammal, characterized by at least one drug reservoir, which can be affixed in the cavity, the drug reservoir and/or a drug outlet being arranged at a distance from the wall, such that the at least one drug is released at a distance from the wall.
