An inflatable and implantable balloon for treatment of degenerative disc disease, bones, lesions, spinal deformities and spinal motion segment instabilities. The balloon is comprised of adjustable and expandable volumes. Further disclosed are methods of forming, inserting, expanding, and implanting the multi-volume balloon for proper placement and stabilization of the spinal lesion or disease. Still further disclosed are kits for aligning and stabilizing elements of the spine.

A balloon catheter has an outer shaft which surrounds a shaft lumen. The outer shaft has a proximal outer shaft portion connected to a distal outer shaft portion. An inner shaft is in a distal portion of the shaft lumen. A guide wire lumen is in the inner shaft. An opening at a proximal end portion of the inner shaft permits the guide wire to be guided out from the outer shaft. A metallic tube is in the shaft lumen. The proximal end portion of the inner shaft is engaged with the metallic tube. A separate, elongate and metallic stiffening element is in the shaft lumen, and is connected to the metallic tube and protrudes from the metallic tube into the distal portion of the shaft lumen and into the proximal portion of the shaft lumen to stiffen portions of the outer shaft.

Balloon catheter and method of producing same

A method for forming a balloon provides a preform that encloses an internal space. The preform is pre-heated to a shaping temperature by passing a heated gas or fluid via an inlet of the preform into the internal space. The preform is then shaped the preform into a balloon. A device is configured to heat a preform using heated gas or fluid to decouple heating from the temperature of a shaping tool.

An implant having a preferably hollow cylindrical basic structure. A nonwoven fabric is disposed in and/or on the basic structure, the nonwoven fabric preferably comprising biocompatible thermoplastic polyurethane and/or a polymer selected from the group consisting of polylactic acid, polycaprolactone, and a copolymer thereof, and/or a polymer including polyphosphazene. At least in at least one section of the implant, preferably at the proximal and/or distal ends of the implant, fastening means are provided or the nonwoven fabric is treated such that, at least in the expanded state of the implant, the protrusion of nonwoven fabric sections from the implant is significantly reduced. Furthermore, a method for producing such an implant is provided.

Implant and method for producing the same

A method for producing a balloon from a suitable blank is provided. The blank is introduced into an outer mold heated an first expanded to expand it against the inner wall of the outer mold. Pressure is reduced to relax the blank away from the inner wall. The three-dimensional volume of the mold is changed. Second expanding of the blank expands again against the inner wall of the changed volume of the outer mold. Balloons of the invention consist of a middle cylindrical region and two end regions delimiting the middle cylindrical region. With a pressure application of 6 bar, a ratio of the cross section in the middle region to the cross section in the end region is at least 2, and preferably greater than 3.

The invention relates to a heart valve prosthesis including a heart valve a main body for supporting the heart valve. The heart valve includes a terminating material selected from material and configured to at least partially close a paravalvular leak by controlled thrombus development.

Packaging has an outer sleeve, which surrounds an interior space for receiving an object, such as a sterilized medical implant. A separate container is arranged in the interior space and surrounds an absorber in a gas-tight manner, such that a gas present in the interior space cannot pass to the absorber. The container is configured to be opened by the application of force when the outer sleeve is closed, such that a gas disposed in the interior space can pass to the absorber and can be absorbed thereby. In preferred embodiments, the absorber absorbs air with the reactive constituents Oand/or HO. Depending on the application, however, other gases can also be absorbed by the absorber. A method for packaging is also provided.

An implant having a preferably hollow cylindrical basic structure. A nonwoven fabric is disposed in and/or on the basic structure, the nonwoven fabric preferably comprising biocompatible thermoplastic polyurethane and/or a polymer selected from the group consisting of polylactic acid; polycaprolactone, and a copolymer thereof, and/or a polymer including polyphosphazene. At least in at least one section of the implant, preferably at the proximal and/or distal ends of the implant, fastening means are provided or the nonwoven fabric is treated such that, at least in the expanded state of the implant, the protrusion of nonwoven fabric sections from the implant is significantly reduced. Furthermore, a method for producing such an implant is provided.

A release device () for detaching a medical implant () from an insertion device (), comprising a body () having a proximal end (), which during use lies furthest from a distal end () of the insertion device (), and a distal end (), which during use faces the distal end () of the insertion device (), wherein at least one first actuator () is provided between the proximal and distal ends (), wherein the at least first actuator () can be tilted about an axis substantially perpendicularly to at least one of the insertion elements () so as to effect a targeted relative movement in the longitudinal direction between the first and second insertion elements () of the insertion device ().

The invention relates to a drug-coated balloon catheter and to a method for producing the same. The balloon of the catheter includes (i) a main membrane, and (ii) an asymmetrical polymer membrane which is applied to an outside of the main membrane and into which at least one pharmaceutical active ingredient is introduced.

Drug-coated balloon catheter and method for the production thereof

An embodiment of the present invention relates to a catheter comprising a dilatable balloon, characterized in that the primary balloon wall is produced from a material that comprises or consists of a polyamide/polyvinylpyrrolidone (PA/PVP) polymer mixture.

Polyamide/polyvinylpyrrolidone (PA/PVP) polymer mixture as catheter material

A balloon catheter, including an outer shaft with a distal end and a fluid line, an inner part located distal anterior to its distal end, as well as a balloon that can be inflated under the influence of a fluid that has been pressurized by the fluid line, that is fastened fluid-tight onto the distal end section of the outer shaft with a first fastening zone at its proximal end, and fluid-tight onto inner part with a second fastening zone at its distal end, whereby the balloon, on at least one of its two ends is designed without cone and with essentially unvarying thin wall thickness, the balloon is provided on at least one of its two ends with respectively one twist anterior to its fastening zone, and a second balloon is placed above the first balloon and is also provided with a twist on at least one of its two ends anterior to the fastening zone, that is directed in the opposite direction of the twist of the first balloon end that is positioned underneath.
