    摘要： A medical electrical lead includes a drug eluting coating provided over at least a portion of the lead body. The drug eluting coating can be provided over at least a portion of the lead body and adjacent to at least one electrode located on the lead body. The drug eluting coating can include at least one matrix polymer layer including a polymer admixed with a therapeutic agent. The therapeutic agent, for example, can be an anti-proliferative agent or an anti-inflammatory agent. The matrix polymer can include a medical adhesive. The rate of elution of the drug from the matrix polymer layer is affected by the drug to polymer ratio of the drug in the matrix polymer layer.

    摘要： A medical electrical lead comprises a flexible, elongate lead body extending along a longitudinal axis and having a proximal end and a distal end. A protective distal tip structure is disposed on the distal end of the lead body. The tip structure includes a plurality of compliant projections each extending distally from the distal end of the body in the direction of the longitudinal axis. The projections are configured to contact and bear against cardiac tissue when the lead is implanted, and are deformable under the action of an axially or radially directed force. The projections optionally include a coating over a substrate. The coating can include a hydrogel material and/or a pharmaceutical agent such as a steroid for reducing inflammation at the implantation site.

    摘要翻译： 医疗电引线包括沿着纵向轴线延伸并且具有近端和远端的柔性细长引线体。 保护性的顶端结构设置在引线体的远端。 尖端结构包括多个顺从突起，每个突起从纵向轴线的方向远离主体的远端延伸。 突起被配置为当铅被植入时与心脏组织接触并承受，并且在轴向或径向力的作用下可变形。 突起任选地包括在基底上的涂层。 涂层可以包括水凝胶材料和/或药剂，例如类固醇，用于在植入部位减少炎症。
