The present invention relates to a medical chamber system () for implantation in the chest of a patient to support the heart activity, preferably by displacing the heart apex (), comprising at least a first chamber () for arrangement inside the heart sac () and a second chamber () for arrangement outside the heart sac (), wherein the chambers () comprise at least one connection portion or connection channel () which connects the two chambers () to each other, the chambers () and the connection channel () are further embodied to be filled with fluid () and, preferably in the implanted state, to be arranged such that the heart activity acts on the first chamber () and that the second chamber () acts as a volume storage and/or energy storage for the fluid (). Furthermore, the present invention relates to an introduction system for a medical chamber system () and to a kit, encompassing a medical chamber system () and an introduction system.

Medical chamber system, introduction system and kit

The present invention relates to a medical apparatus for closing an aperture, an incision, a puncture, a passage through tissue and/or a communication with a blood vessel or other body lumen (short: aperture) of a tissue of a patient, the medical apparatus comprising a closing device holder, for releasably receiving one or more closing devices; and a retracting unit to come into contact with opposite sides of the aperture and for retracting them and/or for spreading the aperture causing it to change its shape into a slit or a slit-like or a more slit-like aperture or to spread or to augment the dimension or diameter of the aperture in at least one or in exactly one dimension of the aperture.

Medical apparatus and method for closing an opening in a tissue

The present invention relates to a device () intended to be attached to or interconnected with a medical implant (), and intended to be attached to or interconnected with a catheter (), the catheter () being intended for implanting the implant (). The invention further relates to a catheter () suited for receiving at least one such device () and to a method.

Implant delivery device adapted to be attached to or interconnected with a catheter, catheter and method

The present invention relates to an apparatus () for use during implanting at least one medical implant () at an implantation site within a patient's body, wherein the apparatus () comprises an aligning device () for aligning the apparatus () at the implantation site, wherein the aligning device () is capable of being transferred from a non-aligning position into an aligning position. It further relates to a set and a method.

Apparatus comprising an aligning device, set and method

A method for crimping a medical implant includes at least one foldable and/or unfoldable structure on or around or over a portion or outer surface of a catheter or of a catheter tip. No pressure beyond a predetermined pressure is exerted on the structure during and/or after crimping of the implant.

Expandable medical implant

A device is intended to be attached to or interconnected with a medical implant, and intended to be attached to or interconnected with a catheter. The catheter is intended for implanting the implant.

An implant, intended to be detachably fixed or crimped on a portion or an outer surface of a catheter for being delivered to an implantation site, includes a longitudinal axis, or an inner space or inner volume longitudinally extending within the implant, and a radial direction perpendicular to the longitudinal axis, space or volume. The implant includes a first structural element having a first portion, a second structural element having a second portion, and one or more interconnecting elements arranged between the first and the second structural elements. In the implant, the first portion and/or the second portion is/are located less radially as regards the longitudinal axis, inner space, or volume than a third portion of the one or more interconnecting elements.

Medical implant maintaining gaps upon crimping, method and delivery device

The present invention relates to an apparatus () for folding or unfolding at least one medical implant () by using at least one tension thread ('), wherein the apparatus () includes a shaft () including a reception area () for receiving the implant (), and a tensioning device for altering a shape of the foldable and/or unfoldable implant () by the tension thread (&#x2032;).

Apparatus for folding or unfolding a medical implant, and implant

The present invention relates to set comprising an apparatus () for folding or unfolding at least one medical implant () by means of at least one tension thread ('), wherein the apparatus () comprises a shaft () and a tensioning device for altering a form or shape of the foldable and/or unfoldable implant () by means of the tension thread (&#x2032;). In at least one shaft section thereof, the shaft () comprises a plurality of individual shaft fibers ().

Set comprising an apparatus and a medical implant

An apparatus for folding or unfolding at least one medical implant by way of at least one tension thread includes a shaft and a tensioning device for altering a form or shape of the foldable and/or unfoldable implant by way of the tension thread ('). In at least one shaft section thereof, the shaft includes a plurality of individual shaft fibers.

Apparatus comprising individual shaft fibers and set for folding or unfolding a medical implant and method

A device is intended to be attached to or interconnected with a medical implant, and intended to be attached to or interconnected with a catheter. The catheter is intended for implanting the implant. A catheter is suited for receiving at least one such device and a method provides a delivery implement with an implant detachably disposed in the device.

Device intended to be attached to or interconnected with a catheter, catheter and method

A catheter for detachably receiving an expandable and/or decollapsible or unfoldable, respectively, implant, in particular a stent may include at least one assembly for controlling the expansion and/or the unfolding or decollapsing, respectively, of the implant from a first diameter to a second diameter and/or its return back from the second diameter to the first diameter. Furthermore, an implant, in particular a stent, and a set including a catheter and an implant are proposed.

Stent which is reduceable again in its diameter from an expanded state in a controlled manner

The present invention relates to an apparatus () for folding or unfolding at least one medical implant () by using at least one tension thread ('), wherein the apparatus () includes a shaft () including a reception area for receiving the implant (), a tensioning device () for altering a shape of the foldable and/or unfoldable implant () by means of the tension thread (&#x2032;), and a separation device for separating the tension thread (&#x2032;) from the implant () and/or for cutting through the tension thread (&#x2032;). The invention further relates to a set and a method.

Apparatus and set for folding or unfolding a medical implant and method

A replacement valve for implantation centrally within the orifice of a malfunctioning native heart valve. The valve is designed for minimally invasive entry through an intercostal opening in the chest of a patient and an opening in the apex of the human heart. The replacement valve includes either a separate anchor () or a combined anchor () that folds around the malfunctioning native valve leaflets, sandwiching them in a manner so as to securely anchor the replacement valve in a precise, desired location.
