Abstract: Methods of manufacturing implantable medical devices with one or more undermolded features are disclosed. An example method includes injection molding an annular-shaped member onto an inner surface of a sacrificial mold insert, and then undermolding an elongate medical device body directly to the member. The member is directly coupled to the device body without the use of adhesives or bonding agents, thus eliminating the presence of gaps or surface irregularities that can affect device performance.

Abstract: A method of manufacturing a medical electrical lead includes molding a lead body pre-form, stringing an electrode onto the pre-form and overmolding the pre-form with a polymer to form a lead body portion. The pre-form has a proximal end, a distal end and at least one lumen extending between the proximal and distal ends. At least one asymmetric region of the pre-form has a transverse cross-section that has a non-circular outer dimension. The overmolding causes the asymmetric region to become substantially circular.

Abstract: A method of forming an implantable medical device includes forming a porous layer of a first material on a substrate, extruding or molding a second material over the porous layer and removing the substrate after extruding or molding the second material to form an implantable medical device.

Abstract: During assembly of a medical electrical lead, the tubular lead component is slid over the outer surface of the lead body to a desired location on the lead. The ends of the tubular lead body are sealed and a space is defined between the inner surface of the tubular lead component and the outer surface of the lead body. Medical adhesive is injected through the port(s) to substantially fill the space between the tubular component and the lead body. The adhesive is then cured. Any ports extending away from the sleeve are removed after the curing step.

Abstract: Specified information can be provided to a user, to a machine, or to an automated process using a specified configuration of a plurality of radiopaque rings about at least a portion of an implantable lead.

Abstract: A tubular lead component includes a sleeve having a lumen and one or more ports located on the sleeve including a bore extending through the sleeve and into the sleeve lumen.
