摘要： Methods and tool kits for implanting a lead subcutaneously. Examples include tool kits and methods for establishing first and second subcutaneous tunnels at an angle relative to one another to facilitate introduction of a lead to the subcutaneous space. In an example, a tunneling tool and lead assembly are advanced simultaneously into the subcutaneous space. The tunneling tool may include a curved region configured to transition the tool from the first subcutaneous tunnel to the second subcutaneous tunnel with the use of a single incision.

摘要： A retention device for use with an implantable medical device (IMD) are disclosed. An illustrative retention device may comprise an elongate body including a configured to receive the lead of the IMD. The retention device may also include securing mechanisms coupled to the elongate body and configured to push against tissue of a patient. The securing mechanisms may also include linking elements coupled to the elongate body and a portion of the securing mechanisms.

摘要： A leadless pacing device may include a power supply providing a power supply voltage, a housing having a first end, a second end, and 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. The housing may be angled to follow a contour of a patient's heart when the housing is positioned within the coronary sinus of the patient's heart. In some cases, an angled portion of the housing may include a smooth-curve. In some cases, an angled portion of the housing may include a first portion of the housing and a second portion of the housing at an angle of less than one-hundred-eighty degrees with respect to the first portion of the housing. One or more of the electrodes may be exposed on a concave side of the angled housing.

摘要： Retainer devices and methods are configured for securing medical devices subcutaneously in a patient. The retainer device may include first and second arms connected by a bridge, the retainer clip configured to move between a first orientation in which lower surfaces of the first and second arms face each other, and a second orientation in which the first and second arms extend laterally from opposite sides of the bridge, wherein the clip is biased in the second orientation. Another example includes a coil and delivery device in which the delivery device holds the coil in a general straight configuration until release; when released the coil wraps about a medical device and holds the device to the subcutaneous tissue.

摘要： Implantation of a cardiac stimulus system using the ITV. Access to the ITV may be performed using the intercostal vein as an access point, and entering the ITV through an ostium therebetween. The intercostal vein may be located on a costal groove on an inferior portion of a rib. Advancement from the intercostal vein to the ITV may then be performed in a superior direction, an inferior direction, or both.

摘要： Cardiac therapy devices in the form of pacemakers and/or defibrillators including one or more leads with electrodes implanted in a vein in a posterior position in combination with one or more leads with electrodes implanted in an anterior position. The posterior position may be chosen from one or more of the azygos, hemiazygos, accessory hemiazygos, or posterior intercostal veins. The anterior position may be chosen from the internal thoracic vein, an anterior intercostal vein, or an anterior subcutaneous location. In other examples, sensors are placed for use by a cardiac monitoring or therapy system in one or more of the internal thoracic vein, the azygos vein, the hemiazygos vein, the accessory hemiazygos vein, and/or an anterior or posterior intercostal vein.

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： A device for the active fixation of an implantable medical lead includes a housing, a tine assembly, and rotatable shaft. The housing includes a proximal end for connecting to the lead and a distal end opposite the proximal end. The housing defines a housing lumen having a longitudinal axis extending between the proximal end and the distal end. The tine assembly is disposed within the housing lumen. The tine assembly includes at least one tine configured to self-bias from a linear configuration within the housing to a curved configuration outside of the housing. The rotatable shaft extends through the housing lumen. The shaft is configured to engage the tine assembly such that rotation of the shaft transitions the at least one tine between the linear configuration and the curved configuration.

摘要： A lead for use with cardiac stimulus device with at least two electrodes positioned at a single longitudinal location is provided. The electrodes may include a shocking coil electrode and a sensing and/or pacing ring electrode and may be separated by an insulating element. The at least two electrically insulated electrodes may be electrically isolated and serve separate purposes in the device.
