Abstract
An interventional medical device, and method of manufacturing the same, is provided to reduce risk to the patient of a fracture of the interventional medical device. At least one portion of the interventional medical device that is subject to fracture and migration within a patient is identified. A membrane is applied over each portion of the interventional medical device that is subject to fracture and migration, such that any fractured portion of the interventional medical device is tied together by the membrane.
Claims22
An ultrasonic catheter, comprising:
- a flexible catheter body having a proximal end, a distal end, and a lumen that extends through the catheter body to the distal end;
- a corewire positioned in the lumen of the flexible catheter body, the corewire having a distal tip, a distal end portion, and a transmission portion, the distal end portion extending proximally from the distal tip and the transmission portion extending proximally from the distal end portion, the distal end portion configured to longitudinally extend in its entirety from the distal end of the flexible catheter body;
- and
- a membrane that encapsulates at least the distal end portion of the corewire, the membrane configured to tie together a fractured portion of the distal end portion of the corewire.
An atherectomy device, comprising:
- an elongate flexible catheter body having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end;
- an ultrasound corewire that extends longitudinally and unattached through the lumen of the elongate flexible catheter body to facilitate excitation of the ultrasound corewire within the elongate flexible catheter body, the ultrasound corewire having a distal end portion and an active distal portion that includes the distal end portion, the distal end portion configured to extend distally past the distal end of the elongate flexible catheter body so that the distal end portion of the ultrasound corewire is fully exposed, and with a portion of the active distal portion being positioned in the lumen;
- and
- a membrane extending along the ultrasound corewire to encapsulate the active distal portion of the ultrasound corewire.

A method of manufacturing an interventional medical device, comprising:
- identifying at least one portion of the interventional medical device that is subject to fracture and migration within a patient;
- and
- applying a membrane over each portion of the interventional medical device that is subject to fracture and migration, such that any fractured portion of each portion of the interventional medical device that is subject to fracture and migration is tied together by the membrane.
