A header assembly (18) for coupling a cardiac lead (14) to a cardiac stimulator (12) is provided. The header assembly (18) includes a header (19) that has a bore (30) for receiving one end of the cardiac lead. The bore (30) has a first longitudinal axis. A connector housing (66) is coupled to the header and has a second bore (68) substantially aligned with the first bore. A biasing member (72) is disposed within the connector housing and has a portion projecting into the second bore to bias the end of the cardiac lead against the walls of the second bore. A set-screw (70) is threadedly coupled to the housing and is operable to secure the cardiac lead to the connector housing when tightened.

L'invention concerne un ensemble de tête (18) permettant le couplage d'un conducteur (14) cardiaque à un stimulateur (12) cardiaque. L'ensemble de tête (18) comprend une tête (19) présentant un alésage (30) pour recevoir une extrémité du conducteur cardiaque. L'alésage (30) possède un premier axe longitudinal. Un boîtier (66) de connecteur, couplé à la tête, présente un second alésage (68) sensiblement aligné avec le premier alésage. Un élément (72) de contrainte est disposé à l'intérieur du boîtier de connecteur et comporte une partie rentrant dans le second alésage de manière à contraindre l'extrémité du conducteur cardiaque contre les parois du second alésage. Une vis (70) sans tête est couplée par filetage au boîtier et peut servir à fixer le conducteur cardiaque au boîtier de connecteur lorsqu'on la visse.
