    摘要： A device and method for accessing a pericardial space of the heart includes a shaft having a cavity at a distal end, a suction lumen terminating in a distal port within the cavity and a hollow needle having a distal tip extending into the cavity. The cavity may be a recess in the shaft into which the distal tip of the needle fixedly protrudes. In other embodiments, the cavity is formed by an inflatable member positioned at the distal end of the shaft and the needle is slidable relative to the shaft. Suction is applied at the cavity to draw a pericardial bleb. The needle pierces the pericardial bleb for accessing the pericardial space and also facilitates delivery of payloads into the pericardial space.

    摘要： The present invention is a myocardial lead attachment system for securing a distal end of a cardiac lead within a myocardium of a patient's heart and anchoring against an epicardium of the patient's heart. The system includes an anchor configured to advance in a first orientation and anchor against an epicardial surface in a second orientation and a tether having a proximal end and a distal end. The anchor is coupled to the distal end of the tether. The system includes a cardiac lead having a lead body, a lumen extending through the lead body, a conductive member, a proximal end, a distal end, and an electrode configured for stimulating the myocardium located at the distal end. The lead body and the lumen are configured such that the lead body can be threaded over the proximal end of the tether and slideably advanced over the tether toward the anchor during implantation. The system includes a fixation mechanism at the distal end of the cardiac lead. The fixation mechanism is adapted to collapse to a first configuration during implantation and deploy to a second configuration after implantation.

    摘要： A lead having a distal end electrode assembly adapted for implantation on or about the heart or within a vein and for connection to a system for monitoring or stimulating cardiac activity. The electrode assembly includes conductive fixation features, such as conductive tines or flexible members, in combination with non-conductive fixation features. The conductive fixation features also include tines coated with a conductive material. The fixation features further include conductive tines which are retractable. A defibrillation coil is optionally disposed at the distal end of the lead in combination with the conductive tines.

    摘要： An apparatus includes a flexible lead body extending from a proximal end to a distal end, the distal end having a biased portion having an outer diameter dimensioned to abut a wall of a pulmonary artery, an electrode coupled proximate the distal end, and an implantable pulse generator electrically coupled to the electrode. The implantable pulse generator is adapted to deliver a baroreflex stimulation signal to a baroreceptor in the pulmonary artery via the electrode.
