Complementary drug delivery sheath for an implantable medical device


A complementary drug delivery sheath for implantable medical devices. The complementary drug delivery sheath is covered, impregnated or otherwise carries one or more drugs. The complementary drug-delivery sheaths are manufactured separately from to the implantable device and are operationally combined with the device subsequent to the device's manufacture and/or sterilization. For example, embodiments of the complementary drug-delivery sheaths may be configured, for example, to attain an implanted position adjacent to one or more surfaces of an implantable medical device. In certain embodiments, the sheath is configured in the form of a glove, pocket, pouch, or the like to receive and to partially or completely wrap around or envelop an implantable medical device. Embodiments of the complementary drug delivery sheath may be implanted into the recipient prior to, concurrently with, or subsequent to the implantation of the implantable medical device.

CROSS-REFERENCE TO REPLATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 12/168,468 entitled “Complementary Drug Delivery Sheath for an Implantable Medical Device”, filed on Jul. 7, 2008, now issued as U.S. Pat. No. 8,160,714 on Apr. 17, 2012, which claims the benefit of U.S. Provisional Patent Application 60/948,411 entitled “Complimentary Drug Delivery Sheath for an Implantable Medical Device”, filed on Jul. 6, 2007. The content of each of these applications is incorporated herein by reference in their entirety.

BACKGROUND

1. Field of the Invention

The present invention relates generally to implantable medical devices, and more particularly, to a complementary drug delivery sheath for an implantable medical device.

2. Related Art

Implantable medical devices are capable of providing a wide range of benefits to a patient. For example, implantable prosthetic hearing devices process ambient sound to supplement or provide hearing ability to hearing impaired patients (sometimes referred to herein as “recipients”).

Implantable prosthetic hearing devices include a category of implantable devices known as Cochlear™ implants (also referred to as Cochlear™ devices, Cochlear™ implant devices, and the like; “cochlear implants” herein). (COCHLEAR is a trademark of Cochlear Limited, Lane Cove, NSW, Australia.) In cochlear implants, an array of stimulation electrodes is implanted in a recipient\'s cochlea. This array is controlled by an electronic system encased in a hermetically sealed, biocompatible housing typically implanted in the mastoid. The electronic system essentially contains decoder and driver circuits for the stimulation electrodes. Acoustic sound reception and conversion of acoustic signals into electrical signals typically occurs externally in a sound processor worn by the recipient. The sound processor superimposes the preprocessed signals, properly coded, on a high frequency carrier signal which is transmitted transcutaneously to the implanted components through the closed skin. A microphone is located outside of the recipient\'s body, typically in a behind-the-ear housing worn on the auricle.

Traditionally, there has been interest in delivering bioactive substances or chemicals (generally and collectively referred to herein as “drugs”) in conjunction with a cochlear implant and other implantable medical devices for a variety of purposes. For example, in one conventional approach the implantable medical device is coated with a bioactive substance. In another conventional approach a bioactive substance is integrated into the polymeric coating of the implantable medical device. In other conventional approaches various techniques for delivering drugs in liquid form to a target location in a patient from an external or implanted reservoir.

These and other conventional approaches typically require the incorporation of the drug into the implantable medical device during the manufacturing process of the device. This introduces a number of difficult problems and challenges for the manufacturing and sterilization processes, particularly for complex implantable medical devices. On the other hand, the use of reservoirs provides significant limitations to many aspects of the administration of the drug therapy.

SUMMARY

In accordance with one aspect of the present invention, a kit of implantable components for implantation in a recipient is disclosed. Embodiments of the kit comprise an implantable medical device and a drug delivery sheath physically separate from the device and configured to be implanted in the recipient proximate to the device, comprising: at least one pannicular substrate configured to be operably positioned adjacent to one or more surfaces of the device subsequent to the device\'s manufacture, and at least one drug carried on the at least one substrate so as to be released into the recipient.

In accordance with a second aspect of the present invention, a complementary drug-delivery sheath for implantation into a recipient of an implantable medical device is disclosed. Embodiments of the complementary drug-delivery sheath comprise: a pannicular substrate having dimensions which enable the sheath to be implanted proximate to one or more surfaces of the device; and at least one drug carried in the substrate for release into the body of the recipient.
