A method for manufacturing a distal portion of a mapping and/or ablation device with fewer components and manufacturing steps than are required for presently known devices. The method generally includes aligning one or more electrodes and electrode wires within a housing mold, overmolding a biocompatible material over the one or more wires and a portion of each of the one or more electrodes, creating a housing component that integrates a dome component and an insulation component. Alternatively, the method generally includes aligning one or more wires within a housing mold so that at least a portion of each wire protrudes from the mold, overmolding a biocompatible material over the one or more wires, thus creating a housing component that integrates a dome component and insulation component. The protruding wire portions are cleaved off and at least a portion of the housing component is coated with a layer of conductive material.

Methods of manufacturing monophasic action potential mapping catheters

A deflection mechanism for selectively inducing a bend in a catheter body includes an elongated deflection wire extending within a deflection lumen of the catheter body and into a handle. A guide track is formed within the handle and a thumb wheel is mounted proximal to the elongated guide track within the handle and supports a pinion gear; the thumb wheel and the pinion gear are adapted to be rotated about a common thumb wheel axis, which extends substantially perpendicular to the longitudinal axis. A rack arm extends obliquely to the longitudinal axis of the handle and includes runners received by the guide track, an attachment point coupling the deflection wire to the rack arm and a linear rack engaging the pinion gear. Rotation of the thumb wheel in a first direction draws the deflection wire proximally through the deflection lumen.

Steerable catheter

A medical lead adaptor that provides a rapid, secure, insulated connection of the lead connector end assembly of one or more implantable cardiac lead with an external medical device is disclosed. The adaptor connector assembly is configured with an elongated bipolar receptacle to accept a bipolar, in-line, or a unipolar lead connector end having common dimensions and with connector pin and ring, bipolar receptacle contacts spaced apart from one another therein. An elongated slot that extends laterally to an adaptor connector assembly exterior surface allows the lateral insertion of a stylet wire into the elongated bipolar receptacle. A separate pair of positive and negative polarity unipolar receptacles are provided for receiving unipolar medical lead connector pins and making electrical and mechanical contact with unipolar receptacle contacts therein. First and second spaced apart contact blades are located within the receptacle housing each having one of the unipolar and bipolar receptacle contacts formed therein. The first and second contact blades are movable together from a normally closed or locked position blocking the receptacles to an open position for allowing insertion or removal of selected lead connector end assemblies into or from the bipolar and/or unipolar receptacles.
