摘要:
Devices, systems, and techniques for managing heat generated in coils for wireless energy transmission are disclosed. Inductive coupling between two coils may be used to recharge the power source of an implantable medical device. A phase change material may be thermally coupled to a flexible coil to absorb heat generated during the inductive coupling and reduce temperature increases of the flexible coil. The flexible coil may be configured to at least one of transmit energy to or receive energy from a second coil, and the phase change material may be configured to deform with the flexible coil and absorb heat from the flexible coil. The phase change material may be contained within thermally conductive tubes or channels configured in shapes that promote flexibility of the flexible coil.

An implantable medical device comprises one or more electrical stimulation generators, and a housing that contains the one or more electrical stimulation generators. The implantable medical device also includes a first medical lead no greater than about 6 inches in length, and a second medical lead no greater than about 6 inches in length. The housing includes a first connector block that electrically connects the first medical lead to at least one of the one or more electrical stimulation generators, and a second connector block that electrically connects the second medical lead to at least one of the one or more electrical stimulation generators. The implantable medical device may be part of an electrical stimulation system implanted beneath the skin and inferior to the inion of a patient to deliver stimulation therapy to at least one of an occipital nerve and a branch of the occipital nerve.
摘要:
A connector assembly of a medical electrical device includes a plurality of electrical contacts and an insulative base that supports the plurality of electrical contacts and extends between the plurality of electrical contacts and a housing of the device, and, wherein at least one contact of the plurality includes an elongate electrical coupling receptacle in which a first part of a feedthrough member extends, being fixedly coupled thereto. The feedthrough member further includes a second part and a bend, which is located between the first and second parts. The second part of the feedthrough member extends away from the contact and through a port formed in the insulative base adjacent to the contact.

摘要:
An implantable medical lead includes a lead body having a proximal portion and a distal portion. The lead also includes first and second contacts located at the proximal portion of the lead body, and includes first and second electrodes located at the distal portion of the lead body. The first electrode is electrically coupled to the first contact and the second electrode is electrically coupled to the second contact. The first contact has a proximal end and a distal end and the second contact has proximal end and a distal end. The second contact is radially spaced apart from the first contact. The contacts do not extend around the lead body. This disclosure also relates to an implantable lead extension and to an implatable signal generator having connectors configured to receive the present lead.

摘要:
A custom implantable medical device (IMD) may be formed based on an image of a structure of a patient, such as the head of the patient. The custom implantable medical device may include a custom member that at least partially encapsulates a module of the IMD, or may include a custom housing that encloses a module of the IMD. The custom member or custom housing may be constructed to conform to a shape determined based on the image. The image of the head of the patient may include an image of a skull of the patient, an image of a scalp of the patient, or an image of vascular or neurological structures in the head of the patient.
