Abstract

Abstract Devices and methods for facilitating transvascular, minimally invasive and other "less invasive" surgical procedures generally include a sheath with an expandable balloon at the distal end, an inflation lumen for expanding the balloon, and a device passage lumen for allowing passage of one or more surgical instruments. The sheath is configured to house at least one visualization device such that an optical element of the device is positioned to view the surgical site. In some embodiments, instruments may be passed through the sheath, with the distal balloon partially or fully circumscribing or encircling the instruments. Any suitable instrument(s) may be passed through sheaths of the invention, such as a surgical clip applier for repairing a heart valve, an ablation member for treating atrial fibrillation, one or more pacemaker leads, a coronary sinus access device or the like.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 149 words
A device for facilitating a procedure on a heart, the device comprising: an elongate sheath having a proximal end, a distal end, a device passage lumen extending therethrough, and at least one inflation lumen, wherein the elongate sheath comprises an inner tubular member having an inner surface defining the device passage lumen, and an outer tubular member disposed over the inner tubular member, wherein the inflation lumen comprises an annular space between the inner tubular member and the outer tubular member; an expandable member coupled with the elongate sheath at or near the distal end, wherein the expandable member defines an aperture, is in fluid communication with the inflation lumen, and extends beyond the distal end of the device passage lumen; a visualization device disposed within the inflation lumen; and an instrument extendable through the device passage lumen and at least partially through the aperture for performing a procedure.
Claim 2
Independent Claim 149 words
A device for facilitating a procedure on a heart, the device comprising: an elongate sheath having a proximal end, a distal end, a device passage lumen extending therethrough, and at least one inflation lumen, wherein the elongate sheath comprises an inner tubular member having an inner surface defining the device passage lumen, and an outer tubular member disposed over the inner tubular member, wherein the inflation lumen comprises an annular space between the inner tubular member and the outer tubular member; an expandable member coupled with the elongate sheath at or near the distal end, wherein the expandable member defines an aperture, is in fluid communication with the inflation lumen, and extends beyond the distal end of the device passage lumen; a visualization device disposed within the inflation lumen; and an instrument extendable through the device passage lumen and at least partially through the aperture for performing a procedure.
Claim 3
Dependent Claim 17 words
The device of claim 1 , wherein the elongate sheath comprises at least one rigid tubular member.
Claim 4
Dependent Claim 17 words
The device of claim 1 , wherein the elongate sheath comprises at least one flexible tubular member.
Claim 5
Dependent Claim 32 words
The device of claim 1 , wherein the expandable member is coupled with the inner tubular member and the outer tubular member at or near the distal end of the elongate sheath.
Claim 6
Dependent Claim 14 words
The device of claim 1 , wherein the outer tubular member is proximally retractable.
Claim 7
Dependent Claim 18 words
The device of claim 1 , further comprising an outer sleeve slidably disposed over the outer tubular member.
Claim 8
Dependent Claim 35 words
The device of claim 1 , wherein the at least one visualization device comprises at least one of a fiber optic device, an ultrasound transducer, a charge coupled device, a light source and a camera.
Claim 9
Dependent Claim 22 words
The device of claim 1 , further comprising at least one Doppler crystal disposed on an outer surface of the expandable member.
Claim 10
Dependent Claim 20 words
The device of claim 1 , wherein a distal end of the visualization device is disposed within the expandable member.
Claim 11
Dependent Claim 18 words
The device of claim 1 , wherein the at least one visualization device is movable within the sheath.
Claim 12
Dependent Claim 13 words
The device of claim 1 , wherein the expandable member is a balloon.
Claim 13
Independent Claim 148 words
A device for facilitating a procedure on a heart, the device comprising: an elongate sheath having a proximal end, a distal end, a device passage lumen extending therethrough, and at least one inflation lumen, a visualization device disposed within the inflation lumen, wherein the elongate sheath comprises an inner tubular member and an outer tubular member, and wherein the inflation lumen comprises an annular space between the inner and outer tubular members, wherein the at least one visualization device is movable around the circumference of the inflation lumen; an expandable member coupled with the elongate sheath at or near the distal end, wherein the expandable member defines an aperture, is in fluid communication with the inflation lumen, and extends beyond the distal end of the device passage lumen; and an instrument extendable through the device passage lumen and at least partially through the aperture for performing a procedure.
Claim 14
Independent Claim 148 words
A device for facilitating a procedure on a heart, the device comprising: an elongate sheath having a proximal end, a distal end, a device passage lumen extending therethrough, and at least one inflation lumen, a visualization device disposed within the inflation lumen, wherein the elongate sheath comprises an inner tubular member and an outer tubular member, and wherein the inflation lumen comprises an annular space between the inner and outer tubular members, wherein the at least one visualization device is movable around the circumference of the inflation lumen; an expandable member coupled with the elongate sheath at or near the distal end, wherein the expandable member defines an aperture, is in fluid communication with the inflation lumen, and extends beyond the distal end of the device passage lumen; and an instrument extendable through the device passage lumen and at least partially through the aperture for performing a procedure.
