First Claim
Patent Images
1. A fixation device for an implantable medical device (IMD) comprising:
- a temporary fixation mechanism configured to be connected to the IMD, wherein the temporary fixation mechanism comprises a biodegradable material and is configured to anchor the IMD within a blood vessel of a patient after implantation until the temporary fixation mechanism biodegrades; and
a chronic fixation mechanism configured to be connected to a first side of the IMD, wherein the chronic fixation mechanism is configured to promote tissue growth that anchors the IMD within the blood vessel before the temporary fixation mechanism biodegrades,wherein the temporary fixation mechanism is configured to anchor the IMD within the blood vessel such that the first side of the IMD including the chronic fixation mechanism is arranged against endothelium of the blood vessel.

21. An implantable medical device (IMD) comprising:
-
a body; a fixation device connected to the body of the device, wherein the fixation device comprises; a temporary fixation mechanism comprising a biodegradable material and configured to anchor the IMD within a blood vessel of a patient after implantation until the temporary fixation mechanism biodegrades; and a chronic fixation mechanism connected to a first side of the body and configured to promote tissue growth that anchors the IMD within the blood vessel of the patient before the temporary fixation mechanism biodegrades, wherein the temporary fixation mechanism is configured to anchor the IMD within the blood vessel such that the first side of the body including the chronic fixation mechanism is arranged against endothelium of the blood vessel. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A method of securing an implantable medical device (IMD) within the body of a patient, the method comprising:
-
arranging the IMD at a target location within a blood vessel of the patient; temporarily anchoring the IMD within the blood vessel with a temporary fixation mechanism comprising a biodegradable material, wherein the temporary fixation mechanism is configured to secure the IMD within the blood vessel after implantation until the temporary fixation mechanism biodegrades; and chronically anchoring the IMD within the blood vessel with a chronic fixation mechanism connected to a first side of the IMD and configured to promote tissue growth that secures the IMD within the blood vessel before the temporary fixation mechanism biodegrades, wherein the temporary fixation mechanism is configured to anchor the IMD within the blood vessel such that the first side of the IMD including the chronic fixation mechanism is arranged against endothelium of the blood vessel.
