Patent number: 8504168Abstract: A connection made between a contact and a conductor in an implantable lead assembly includes a slot, formed in the contact, and a crimp sleeve, attached to the contact; wherein the crimp sleeve includes a contact coupling, which rests within the contact slot, and a conductor coupling, crimped around the conductor, within a body of the lead assembly. The conductor coupling of the crimp sleeve may be pushed through the contact slot, anywhere along a length of the slot, so that the contact coupling comes to rest between opposing edges of the slot. A preferred profile of the contact coupling of the crimp sleeve is such that the contact coupling rests within the contact slot, without falling through to the inside diameter of the contact, prior to attachment thereto.Type: GrantFiled: December 7, 2010Date of Patent: August 6, 2013Assignee: Medtronic, Inc.Inventor: Mary Lee Cole

Patent number: 6240322Abstract: A medical device is insertable and/or implantable into a body of a patient. The medical device includes a plurality of hollow and/or collapsible tines which are adapted to assist in deployment of the medical device into the body and in preventing inadvertent removal or dislodging of the medical device from the body. The tines are coupled to the medical device body at a coupling end and extend away from the device to a free end. The tines can have a number of configurations such as cylindrical or cone shaped. In addition, the cross section of the free end of the tines can be elliptical, where the free end extends to a tip. Another cross section includes a semi-circle including an open portion which can face towards or away from the medical device body. The tines also include coiled structures which can have a radial axis perpendicular to the radial axis of the medical device.Type: GrantFiled: November 4, 1998Date of Patent: May 29, 2001Assignee: Cardiac Pacemakers, Inc.Inventors: Randall M.
