An arrangement of an expandable substrate and a strain sensor applied onto a surface of the substrate. The strain sensor is made from an ink composition that is a mixture of a conductive silver ink and a conductive carbon ink. A ratio between the conductive silver ink and the conductive carbon ink lies in a range between 30:70 and 70:30 in on arrangement and between 40:60 and 60:40 in another. A method for forming the arrangement directly prints the strain sensor on the substrate.

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.

Angulated rings and bonded foils for use with balloons for fusion and dynamic stabilization

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.

Method and device for forming a balloon

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.

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.

Encapsulated absorber and temporal activation thereof

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

A balloon catheter, in particular for delivering medicaments, stents or medicament-coated stents in the region of a stenosis, comprising

Balloon catheter, in particular for delivering drugs or stents in the region of a stenosis

A catheter having a balloon () which has at least one wing () in the undilated state, the balloon having at least one fold element () running essentially in the longitudinal direction for each wing (), such that in folding the balloon (), the fold element is arranged in an area of the wing () with a minimum in the bending radius, said area running in the longitudinal direction. Also disclosed is a system for introducing an intraluminal endoprosthesis, preferably a stent, into a body cavity consisting of an intraluminal endoprosthesis and a catheter having the balloon as described. Further, disclosed are methods of producing such a catheter and such a system.

Catheter, system for inserting an intraluminal endoprosthesis and method for manufacturing same

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 comprises an outer shaft having a distal end, an inner shaft situated therein to form an annular fluid line and projecting beyond the distal end of the outer shaft, and a balloon which is dilatable under the influence of a fluid introduced through the fluid line under pressure. At its proximal end the balloon is attached in a fluid-tight manner to the distal end region of the outer shaft at a first attachment zone, and at its distal end is attached in a fluid-tight manner to the distal end region of the inner shaft at a second attachment zone. Between the attachment zones, in the undilated state the balloon is placed in longitudinal folds along its length. The balloon, at least at its distal end, has an untapered design with a thin wall thickness (d) which is essentially unchanged over the length of the balloon, and the longitudinal folds extend into the attachment zone at that location.

Balloon catheter and method for manufacturing same

A combined rolling membrane-balloon catheter, in particular for expanding stenoses in bodily vessels, including: an outer shaft () and an inner shaft () which is axially displaceable therein, an intermediate shaft () situated between the inner and outer shafts () which is likewise axially displaceable, a rolling membrane () which is attached in a pressure-tight manner between the distal end () of the outer shaft () and the distal end () of the inner shaft (), and which may be displaced between a passive position within the outer shaft () and an active position which is distally expanded from the outer shaft () by the action of pressure, and a dilatable balloon () which is attached in a pressure-tight manner between the distal end () of the inner shaft () and the distal end of the intermediate shaft (), and which may be displaced between a passive position within the outer shaft () and proximally in front of the rolling membrane (), and an active position which is distally expanded from the outer shaft (), within the rolling membrane (), by the action of pressure.
