Abstract
A boot manufactured from a bio-compatible material is used to smooth the external shape of an implantable medical device and to seal the device against fluid intrusion.
Claims3
A method of making an implantable medical apparatus, the method comprising:
- (a) introducing a medical device for delivering therapy to a patient into a boot made of bio-compatible material and having an opening formed therein such that the boot is adapted to receive the medical device;
- and
- (b) sealing the boot to the medical device by applying adhesive at the interface between the edge of the boot opening and the medical device to prevent fluid intrusion between the boot and the medical device.
A method of making an implantable medical apparatus, the method comprising:
- (a) expanding a boot made of bio-compatible material and having an opening formed therein, the opening being undersized in its contracted state with respect to the size of the medical device such that the opening is adapted to receive a medical device;
- (b) sliding the medical device into the opening while the opening is expanded;
- and
- (c) contracting the opening such that the boot forms a press fit on the medical device, thereby preventing fluid intrusion into the interface between the boot and the medical device.

A method of making an implantable medical apparatus, the method comprising:
- (a) applying freon to a boot made of bio-compatible material and having an opening formed therein, the opening being undersized in its contracted state with respect to the size of a medical device, such that the opening expands to be adapted to receive the medical device;
- (b) sliding the medical device into the opening while the opening is expanded;
- and
- (c) contracting the opening as the freon dissapates such that the boot forms a press fit on the medical device, thereby preventing fluid intrusion between the edge of the boot opening and the medical device.
