Torque lock anchor and methods and devices using the anchor

A lead anchor includes a body defining a lead lumen having a first opening and a second opening through which a lead can pass. The body further defines a transverse lumen that intersects the lead lumen. An exterior member is disposed around at least a portion of the body. The exterior member is formed of a biocompatible material. A fastener anchors the lead to the body through the transverse lumen by deforming a portion of the lead. The transverse lumen is configured and arranged to receive the fastener. At least one suture element is defined by the exterior member and is configured and arranged for receiving a suture to suture the lead anchor to patient tissue.

Anchors including rigid bodies defining full length slots for use with implantable medical leads

Anchors for use with implantable medical leads include an elastic body containing one or more rigid bodies that have longitudinal free edges. The longitudinal free edges run from end to end to define full length slots. Partial length slots may also be included within the one or more rigid bodies. The full length and partial length slots allow for deflection of the rigid bodies against the body of an implantable medical lead to hold the anchor in place on the lead. The full length slots allow a blade to pass through and cut a slit in the elastic body which allows the anchor to be removed from the lead.

An implantable therapy lead is disclosed herein. In one embodiment, the therapy lead includes an elongated lead body and a suture sleeve. The elongated lead body has a proximal region and a distal region opposite the proximal region. The suture sleeve is supported on the lead body and has a proximal end, a distal end opposite the proximal end, an outer surface extending between the proximal end and distal end, and an inner surface radially inward of the outer surface and extending between the proximal end and distal end. The inner surface defines a lumen through which the elongated lead body extends. A helical structure helically extends about a longitudinal center axis of the lumen and along the inner surface.

ESTABLISHING CONTINUITY BETWEEN A SHIELD WITHIN AN IMPLANTABLE MEDICAL LEAD AND A SHIELD WITHIN AN IMPLANTABLE LEAD EXTENSION
20170224984 · 2017-08-10 ·

Implantable medical leads and implantable lead extensions include a shield. The implantable medical lead is coupled to the implantable lead extension. Stimulation electrodes of the implantable medical lead contact stimulation connectors within a housing of the implantable extension to establish a conductive pathway for stimulation signals from filars of the implantable extension to filars of the implantable medical lead. Continuity is established between the shield of the implantable medical lead and the implantable extension by providing a radio frequency conductive pathway within the housing. The radio frequency conductive pathway extends from a shield of the implantable extension to a shield connector that contacts a shield electrode of the implantable medical lead. The radio frequency conductive pathway may have various forms such as a jumper wire or an extension of the shield within the implantable extension.

STRAIN RELIEF LOOP HOLDERS FOR MEDICAL LEADS AND SYSTEMS
20170182313 · 2017-06-29 ·

Strain relief loop holders maintain the strain relief loop formed in a lead while also addressing the excessive heating at the point in the loop where the medical lead intersects with itself. The strain relief loop includes a body section that the medical lead passes through where the intersection occurs. The body section may be a thermal non-conductor and isolate from excessive heating at the intersection point or may be a thermal conductor and distribute the excessive heating. The strain relief loop may include features such as arms or a coil extending from the body segment with arm segments at the ends of the arms defining lead passageways that assist in maintaining the strain relief loop. The body segment may have a single lead passageway where the intersection point occurs or may have multiple lead passageways. The body itself may house the loop by forming a loop or a capsule.

SYSTEM AND METHOD FOR SECURING AN IMPLANT TO TISSUE

A system and method for securing a medical implant within a patient. The method comprises disposing an anchor element around the implant, the anchor element including a pair of tabs each including an eyelet, and a flexible intermediate portion between the tabs, wherein disposing the anchor element around the implant includes positioning the implant within the intermediate portion and folding the anchor element such that the tabs contact one another and the eyelets aligned. The anchor element is positioned at a desired implantation position with the tabs positioned proximate soft tissue of the patient. The method further comprises inserting a distal tip of a fixation element delivery tool through the eyelets and into the soft tissue, the fixation element including at least one tissue anchor and an adjustable suture arrangement coupled to the tissue anchor. The at least one tissue anchor is deployed from the delivery tool and into the soft tissue of the patient. The delivery tool is withdrawn from the soft tissue and the eyelets of the anchor element, and the adjustable suture arrangement is tightened to secure the anchor element against the soft tissue.
