Abstract: Adjustable balloon catheter including an inner tubular member that has an inflation lumen defined therein. An expandable member is coupled to the distal end portion of the inner tubular member and has an inner chamber in fluid communication with the inflation lumen. The expandable member is transitionable between a deflated configuration and an inflated configuration. The expandable member defines has a non-cylindrical shape along at least a portion of a working length thereof when in the inflated configuration. An outer tubular member is movable relative to the inner tubular member, the outer tubular member includes a distal end. The outer tubular member is moveable between an extended position disposed over the expandable member and a retracted position proximal to the extended position. The outer tubular member is selectively positioned between the extended position and the retracted position to define an exposed length of the working length of the expandable member.

Abstract: The present invention refers to medical devices. Particularly it relates to stent devices and balloon catheter devices. In the most particular aspect of the invention it relates to balloon catheter devices carrying stents (2) with the medical balloon (3) comprising an inner layer (4) having a lower compliance rate and/or burst pressure than the outer layer (5) and an outer layer (5) having on the outer surface (6a) a higher adhesion strength than the inner layer (4), and its use in a variety of medical procedures to treat medical conditions in animal and human patients.

Abstract: A medical balloon for deployment of stents is disclosed. The medical balloon includes a central section; a proximal and a distal cone section; a proximal and a distal shaft section; a proximal sleeve which is arranged coaxial to and radially inside the proximal shaft section. The proximal end of the proximal shaft section is permanently connected and/or unitarily formed with the proximal end of the proximal sleeve, and distal thereto, at least part of the proximal cone section is connected with the proximal sleeve by an adhesive bond, and a distal sleeve which is arranged coaxial to and radially inside the distal shaft section. Methods of manufacturing a medical balloon are disclosed.

Abstract: The present invention refers to medical devices comprising a non-metallic micro tube containing FRP (fiber reinforced polymer), especially to respective tubings, used for constructing catheters like balloon dilation catheters, stent delivery catheters, guiding catheters and diagnostic catheters.

Abstract: The present invention relates to a stent delivery system and a process for mounting a stent onto a delivery system. More specifically, the present invention relates to a method of loading a stent onto a balloon and mounting the stent balloon assembly onto a catheter. The premounting of the stent onto the balloon subassembly allows the stent to be crimped in a way that the crimping recoil can be compensated and stent retention is kept at a maximum.

Abstract: An interluminal medical treatment device configured to treat a targeted treatment site within a body lumen. The interluminal medical treatment device can include an elongated generally tubular outer member. The outer member can include an expandable distal portion, an expandable proximal portion, and a central portion of limited expandability. The interluminal medical treatment device can include at least one membrane. The outer member and at least one membrane may define a housing area positioned between the proximal portion and distal portion of the outer member. The outer member and at least one membrane can be configured to redirect fluid flow within a body lumen away from the housing area inner member or inner passageway.

Abstract: Implants and methods of making same are provided for treatment or prophylaxis of coronary or peripheral vascular constrictions or vascular occlusions, and particularly, stenoses or restenoses, that comprise FK506 in chemically covalently bound, non-covalently bound or physically immobilized form.

Abstract: An expandable stent for implantation in a body lumen, such as coronary-artery, and methods for manufacturing such a stent are provided, whereby the stent comprises at least one radially expandable cylindrical crown covered with a polymeric tube. The at least one crown is generally aligned on a longitudinal axis of the stent and connected to at least one further stent segment with highly flexible connectors formed from the same or different polymeric material as the crown covering material. In a preferred embodiment the cylindrical crown is loaded or coated with a therapeutic active agent.
