摘要： Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an implantable medical device. The implantable medical device may include an implantable pacing member having a housing and a lead input. A lead may be coupled to the lead input. The lead may be designed to extend along a pericardial space, epicardium, or both and engage a heart chamber. A passageway may be defined along a portion of the length of the lead.

摘要： Implantable device systems include an electrical lead with one or more electrodes and a shield. The shield is attached to the electrical lead with the shield covering a first side of the electrode and extending laterally away from the electrode. The shield directs energy from at least one of the electrodes of the the electrical lead in a direction away from the shield.

摘要： Implantation of a cardiac stimulus system using the ITV. Superior, intercostal, and inferior access methods are discussed and disclosed. Superior access may be performed using the brachiocephalic vein to access the ITV, with access to the brachiocephalic vein achieved using subclavian vein, using standard visualization techniques. A positioning mechanism may be advanced to the ITV, a location of the positioning mechanism may then be obtained, and an external access may then be established. Inferior external access may be accomplished inferior to the lower rib margin via the superior epigastric or musculophrenic vein. Intercostal external access may be accomplished via an intercostal vein between two ribs. A lead may then be attached to the positioning mechanism and drawn into the ITV.

摘要： A leadless pacing device may include a power supply for providing a power supply voltage, a housing having a first end and a second end with a side extending between the first end and the second end, and a set of electrodes supported by the housing and in communication with the power supply. When leadless pacing device is disposed within a coronary sinus of a patient's heart, the housing may facilitate blood flow across the housing. The housing may include fixing members extending radially outward from the side of the housing to engage a wall of the coronary sinus and expand the coronary sinus to allow blood to flow past the housing. In some cases, the housing may have a recess along a length thereof that allows blood to flow past the housing. The recess may include a groove, a flat feature, or other feature.

摘要： An IMD may include a housing with a controller and a power supply disposed within the housing. A distal electrode may be supported by a distal electrode support that biases the distal electrode toward an extended position in which the distal electrode extends distally from the distal end of the housing and allows the distal electrode to move proximally relative to the extended position in response to an axial force applied to the distal electrode in the proximal direction. In some cases, the distal electrode support may include a tissue ingrowth inhibiting outer sleeve that extends along the length of the distal electrode support and is configured to shorten when the distal electrode moves proximally relative to the extended position and to lengthen when the distal electrode moves back distally toward the extended position in order to accommodate movement of the distal electrode.

摘要： Tools adapted to allow a fixation device to be applied near the distal end of an implantable lead, and methods for using such tools. Preparing the lead for implantation may be performed by placing a tool over a distal tip of the lead, moving a fixation device from the tool to the lead, and placing the fixation device the lead.

摘要： A subcutaneous implantable cardioverter-defibrillator (S-ICD) comprising shocking electrodes configured to reduce the defibrillation threshold. The S-ICD may include a canister housing a source of electrical energy, a capacitor, and operational circuitry that senses heart rhythms and an electrode and lead assembly. The electrode and lead assembly may comprise a lead, at least one sensing electrode, and at least one shocking electrode. The at least one shocking electrode may extend over a length in the range of 50 to 110 millimeters and a width in the range of 1 to 40 millimeters.

摘要： An illustrative anchoring mechanism is provided for attachment to an implantable subcutaneous lead to facilitate anchoring at the distal tip of the lead. The anchoring mechanism is attached to an opening in a distal portion of a subcutaneous lead prior to implantation. The anchoring mechanism may be designed to avoid covering the sensing electrode of the subcutaneous lead, to prevent interference with sensing. Use of such an apparatus may reduce the number of incisions needed to perform implantation.

摘要： Implantation of a cardiac stimulus system into the mediastinum using the ITV. Superior, intercostal, and inferior access methods are discussed and disclosed. Superior access may be performed using the brachiocephalic vein to access the ITV, with access to the brachiocephalic vein achieved using subclavian vein, using standard visualization techniques. Inferior access may be accomplished inferior to the lower rib margin via the superior epigastric vein. Intercostal access may include creating an opening in an intercostal space between two ribs and advancing a needle using ultrasound guidance. Once in the ITV, access is then made into the mediastinum for placement of at least a portion of a lead of the cardiac stimulus system therein.
