An implantable medical system for delivering pacing pulses to HIS bundle of a heart of a patient when implanted in said patient includes a medical lead, which is adapted to be attached with a distal end to tissue of said heart, including a at least two electrodes arranged being electrically separated from each other. The implantable medical device connectable to the medical lead includes a pacing circuit adapted to deliver the pacing pulses to said heart via the medical lead, a selection device connected between the pacing circuit and the electrodes adapted to selectively activate at least one of said electrodes, and a processing device adapted to control the selection device to selectively activate at least one of the electrodes to direct the pacing pulses to the HIS bundle.
摘要:
In a method for manufacturing active fixation helices for the stimulation and/or sensing of organs, an elongated helix precursor body is produced that has one or more electrical conductors surrounded by an insulating material. This helix precursor body is then shaped into a helix, material removed in predetermined places in order to expose the areas of the conductors which will be used as electrodes in the final product. The body is coated with an electrically conducting biocompatible coating which is subsequently partly removed in continuous loops from around the electrodes in order to electrically insulate them from each other and to ensure that the electrically active areas of the electrodes are of the correct dimensions.

A pleatable filter structure for use in a filter panel, containing ion exchange particles distributed within a fibrous framework is expanded to contain enough space to allow the ion exchange particles to swell or to be in a swelled state as compared to dry ion exchange particles, without additional expansion of the filter structure. A method of manufacturing the filter structure involves subjecting the filter structure to a moisture treatment in which it is exposed to a humid or water containing environment, whereby the ion exchange particles swell and cause a permanent expansion of the filter structure.

A medical implantable lead is adapted to be implanted into a human or animal body for monitoring and/or controlling of an organ inside the body. The lead has in a distal end, a combined fixation means and electrode member in form of a helix, which is connected to a rotatable tubular member being connected to a rotatable member at a proximal end of the lead, and which is rotatable in relation to the lead and extendable out from the distal end, by rotation of the control member and the tubular torque transferring member, to be able to fixate the distal end of the lead to the organ by being screwed into the tissue. The helix is electrically connected to a connector at the proximal end by means of at least one electrically conducting wire formed as an electrically conducting coil, which is separate from the tubular torque transferring member and unrotatable in relation to the lead and that has one or more individual wires, each including an electrically conducting wire core and a surrounding electrically insulating layer, wherein the rotatable control member is rotatable within the connector.

The present invention relates to methods for manufacturing active fixation helices for the stimulation and/or sensing of organs. A first embodiment of a method in accordance with the present invention for making a helix comprises a first step of producing an elongated helix precursor body comprising one or more electrical conductors surrounded by an insulating material. This helix precursor body is then shaped into a helix, material removed in predetermined places in order to expose the areas of the conductors which will be used as electrodes in the final product. The body is coated with an electrically conducting biocompatible coating which is subsequently partly removed in continuous loops from around the electrodes in order to electrically insulate them from each other and to ensure that the electrically active areas of the electrodes are of the correct dimensions.

摘要:
An implantable lead has a distal lead portion with at least one electrode electrically connected to a connector ring through a conductor running in a lumen of the lead. A proximal lead portion includes the connector ring, a connector pin and a connector coupling mechanically and coaxially connected to each other with the connector coupling as a bridging element. A rotational lock in the form of a circumferential element of an elastically deformable, flexible material is provided in the connector coupling in the interface between the coupling and the connector ring. This rotational lock prevents any rotation of the connector pin to be propagated into a rotation of the connector coupling and consequently reduces the risk of damages to internal lead components due to any such unintentional coupling rotation.

An implantable medical lead (1) comprises multiple electrodes (22, 24, 26, 28) arranged at a distal end (2), multiple electrode terminals (32, 34, 36, 38) at a proximal end (3) and a lead body (4) with an insulating tubing (40). A conductor coil (10) comprises a coiled tubular insulator (19) having multiple separate lumens (12, 14, 16, 18). Each lumen (12, 14, 16, 18) houses a respective conductor (11, 13, 15, 7), which is movable in the lumen (12, 14, 16, 18) relative the coiled tubular insulator (19). The conductor coil (10) is arranged in a bore (42) of the insulating tubing (40) and each conductor (11, 13, 15, 7) is electrically connected to one of the electrodes (22, 24, 26, 28) and one of the electrode terminals (32, 34, 36, 38).
