  • Patent number: 11456119
    Abstract: In an embodiment an electrolytic capacitor includes a capacitor element being housed by a can. A covering element is configured to close an opening of the can. A connection element comprises an external terminal for applying an electrical signal and a lead tab being electrically coupled to the capacitor element and to the external terminal. The connection element comprises an upper washer and a lower washer respectively having an opening to receive a rivet to fix the external terminal and the lead tab to the covering element. The upper washer is configured to either comprise a cavity to receive a head of the rivet or a protrusion or a tapered lateral surface.

  • Patent number: 11437197
    Abstract: In an embodiment an electrolytic capacitor includes a covering element configured to close an opening of a can comprising a capacitor element. A connection element comprises a lead tab for applying an electrical signal to the capacitor element and a rivet having a first head to fix the lead tab to the covering element. The connection element includes an upper washer arranged between the first head of the rivet and the lead tab. The lead tab has a first section having a first opening and a second section having a second opening. The lead tab is folded such that the first opening and the second opening of the lead tab are arranged above each other. The rivet is arranged in the first and second openings of the lead tab and in an opening of the upper washer.

  • Patent number: 8784860
    Abstract: Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. These therapeutic drugs, agents or compounds may also further reduce a biological organism's reaction to the introduction of the medical device to the organism. In addition, these therapeutic drugs, agents and/or compounds may be utilized to promote healing, including the formation of blood clots.

  • Publication number: 20070128242
    Abstract: The present invention relates to polymeric compositions for controlled release or delivery of pharmacologically active agents. Each polymeric composition comprises a biocompatible polymeric matrix containing at least one pharmacologically active agent that is susceptible to oxidative degradation. The biocompatible polymeric matrix comprises at least a first polymeric material with an active antioxidant functional moiety covalently bound thereto in sufficient amount for protecting the at least one pharmacologically active agent against oxidative degradation. Optionally, the biocompatible polymeric matrix further comprises a second polymeric material that is essentially free of covalently bound active antioxidant functional moiety. The present invention also relates to a medical device that comprises an implantable structure, while at least a portion of the implantable structure either comprises or is coated with at least one of the above-described polymeric compositions.
