  • Patent number: 8888847
    Abstract: A cover for receiving an implantable medical device includes self-anchoring protrusions that engage tissue of a pocket where the device is implanted to resist movement including rotation and flipping. The implantable medical device is placed into the cover prior to being placed into the pocket so that once in the pocket, the device may reduce rotating, flipping, or otherwise moving. The self-anchoring protrusions may include barbs of various shapes to frictionally engage the tissue of the pocket. The cover may include features such as a strap and elastic construction to assist in holding the implantable medical device within the cover. Apertures may be included to enable the device. The cover may include additional features like suture tabs to allow additional fixation via suturing the cover to the surrounding tissue.

  • Patent number: 7044932
    Abstract: An implantable drug pump and an access template for locating the implanted pump refill septum, also known as a refill port, or cathether access port are disclosed. The access template comprises a denial surface, an access port, and template labeling. The denial surface has a periphery with a location diameter and an alignment feature. The denial surface is configured to prevent penetration through a dermal layer into the implantable drug pump. The access port carried on the denial surface is configured to permit penetration through the dermal layer. The template labeling uses a label color that is substantially the same color as needle labeling color for a needle sheath covering a needle that is intended to access an implantable drug pump. The access template can be configured into a wide variety of apparatus and method embodiments.
