The disclosure is directed to a tissue ablation device comprising an elongate probe, with a tissue ablation member located at the deflectable distal end of the probe, which is configured to access a patient's heart. The elongate probe is attached at its proximal end to a handpiece which is ergonomically designed to fit within the hand of the operator. The handpiece houses an advancement mechanism which is mechanically coupled to the tissue ablation member and can be used to axially translate the tissue ablation member in relation to the elongate probe. An activation mechanism is housed within the advancement mechanism and is coupled to the advancement mechanism in such a manner that the operator can simultaneously activate and advance the tissue removal member with one finger or thumb. The handpiece also houses a deflection actuator which applies tension to a tensile member which deflects the distal end of the probe.

Minimally invasive TMR device

An laser device for forming channels within an outer wall of a patient's heart which has an elongated optical fiber, a lens or probe tip secured to the distal end of the optical fiber and means to limit the penetration of the probe tip or lens. Preferably, an outer support sleeve is secured to the proximal portion of the probe tip and a distal portion of the optical fiber proximal to the probe tip. In one preferred embodiment of the invention, a helical coil is disposed between the distal portion of the optical fiber and the proximal portion of the probe tip to ensure a better bond therebetween, particularly when the optical fiber has a lubricous fluoropolymer coating.

Channel forming device with penetration limiter

An intravascular device for forming a channel within a patient's ventricular wall which engages the tissue of the ventricular wall to prevent undesirable movement of the channel forming device while forming the channel.
