Abstract
Abstract An ablation system (10) for ablating cardiac tissue within a chamber of the human heart including a guiding introducer system (11), a rail (16), one end of which is contained within the guiding introducer system (11) and an ablation catheter system (18) which is supported by the guiding introducer system (11). The guiding introducer system (11) may be a single or multiple guiding introducers. The ablation system (18) may include a slotted sheath (22) which passes over the rail (16) which supports the ablation catheter system (18).

Independent Claim
80 words
A rail catheter ablation and mapping system for ablation
procedures in a chamber of the heart, comprising; an inner and outer guiding introducer, each containing a
lumen, an extendable rail, one end of which is contained within the
guiding introducers, wherein the rail is extendable from the inner
and outer guiding introducer, and an ablation catheter containing a lumen, wherein the catheter
passes through the lumen of the inner guiding introducer, and
wherein the ablation catheter passes over the rail.
Claim 2
Dependent Claim
73 words
A rail catheter ablation and mapping system for ablation
procedures in a chamber of a human heart, comprising; a guiding introducer containing a lumen, an extendable rail, one end of which is contained within the
guiding introducer, wherein the rail is extendable from the guiding
introducer, and an ablation catheter containing a lumen, wherein the catheter
passes within the lumen of the guiding introducer, and wherein the
ablation catheter passes over the rail.
Claim 3
Dependent Claim
65 words
A rail catheter ablation and mapping system for ablation
procedures in a chamber of a human heart, comprising; a guiding introducer containing a lumen, an extendable rail contained within the guiding introducer, a slotted sheath contained partially within the lumen of the
guiding introducer, wherein the slotted sheath passes over the
rail, and an ablation catheter, which passes through a lumen of the
slotted sheath.
Claim 4
Dependent Claim
59 words
A rail catheter ablation and mapping system for ablation
procedures in a chamber of a human heart comprising a guiding introducer containing a lumen, and an extendable rail, one end of which is contained within the
guiding introducer, wherein the rail passes through the lumen of
the guiding introducer and wherein the rail is extendable from the
guiding introducer.
