Abstract

A device (1) that can be implanted under the outside of a heart (2) for measuring biometric blood parameters, such as, for example, blood pressure, has at least one sensor (3), which can be analyzed telemetrically or by means of transponder technology and which is arranged on or in a housing (4), wherein, a holder for fixing the sensor (3) or its housing (4), for example, in the interior of a heart wall, is also provided. A pin-like anchor (7), which can be inserted into or through the outer wall (5) of the heart (2) and/or the intermediate wall (6) and which is fixed to a pulling element (8) or thread that is connected in the position of use to the sensor (3) or a housing (4) in a suitable way directly or via an opening (13) running in the longitudinal direction. The anchor is formed so that it is held, on one side, in a puncturing cannula (10) and can be moved or inserted, on the other side, with the help of a tool (9) or needle relative to this puncturing cannula (10) and/or through the heart wall (5). In the position of use, a counter anchor (12), for example, a stitch, is provided at the end of the pulling element (15) attached to the opposite end of the housing (4).

Claims

1. Device (1) for implantation under an upper or outer surface of a heart (2) for measuring biometric blood parameters, such as blood pressure, blood composition, pH value of the blood, blood-sugar level, temperature, comprising at least one sensor (3) that can be analyzed telemetrically or by transponder technology and with a holder for fixing the sensor (3) or a housing (4) containing the sensor on or in the heart (2), a pin-like anchor (7), which can be inserted from the outside of the heart (2) into or through an outer wall (5) of the heart (2) and/or an intermediate wall (6) and which is fixed to a pulling element (8) or thread connected to the sensor (3) at least in a position of use, the pulling element or thread is provided as a holder for the sensor (3) or the housing (4), wherein the pulling element (8) or the thread attaches to the pin-like anchor (7) between two ends thereof, and the anchor (7) can be pushed or inserted from outside into or through the heart wall (5) by a tool (9) or needle.

2. Device according to claim 1, wherein the anchor (7) can pivot relative to the pulling element (8) about an attachment point to the pulling element.

3. Device according to claim 1, wherein a deformation, which can be coupled detachably to the tool (9) or needle, is provided on an end of the anchor opposite a piercing tip (7a) or piercing end thereof as an attachment point for the tool (9) or the needle to the anchor (7).

4. Device according to claim 3, wherein the anchor (7) has a reduced cross section at a back side thereof in the insertion direction and facing away from the tip (7a) or insertable end for one end of the tool (9) and/or a receptacle opening (11) located in the anchor that is open at the back side and closed at an opposite end for the tool (9) or the needle to be received in the receptacle opening, so that the anchor (7) can be moved into a position of use.

5. Device according to claim 1, further comprising a puncturing cannula (10), whose hollow interior corresponds approximately to an outer cross section of the anchor (7) at least at an outer or distal end (10a) thereof and which holds the anchor (7) at least partially, and the thread or the pulling element (8) extends on an outside of the puncturing cannula (10).

6. Device according to claim 1, wherein the housing (4) of the sensor (3) has an approximately cylindrical cross-sectional form with at least one, rounded and/or pointed end, and the pulling element (8) attaches to or near one or both ends of the housing (4) at least in a position of use.

7. Device according to claim 1, wherein the housing (4) of the sensor (3) or the sensor itself has an opening (13), which extends in a longitudinal direction and through which it can be moved via the thread or the pulling element (8) of the anchor (7), so that the sensor (3) can be moved into a position of use by the thread (8) after installation of the anchor (7).

8. Device according to claim 1, wherein an end of the pulling element (8) or thread projecting past the sensor on a side facing away from the anchor in the position of use is provided with a counter anchor or stitch to form a counter holder.

9. Device according claim 1, wherein the sensor (3) that is movable with the pulling element (8) carries an additional thread (15), by which the sensor can also be positioned opposite a direction of pushing or can be removed again from the heart (2).

10. Device according to claim 9, wherein the pulling element (8) with the anchor (7) attaches to one side of the sensor (3) and the pulling element (15) for a counter anchor (12) or stitch attaches to an opposite side.

11. Device according to claim 1, wherein the housing (4) of the sensor (3) is composed of biocompatible material and has a small cross section in relation to a length thereof.

12. Device according to claim 1, wherein in the housing (4) of the sensor (3) there are at least two pressure detectors (3), which are spaced apart from each other or which are arranged opposite each other in or on the housing (4).

13. Device according to claim 10, wherein the counter anchor (12) includes at least a portion of electronics of the sensor (3).

14. Device according to claim 1, wherein the housing (4) of the sensor (3) has an approximately cylindrical cross-sectional form with opposing rounded and/or pointed ends, and the pulling element (8) attaches to or near one or both ends of the housing (4) at least in a position of use.
