US 2010/0168837 A1 · BLOOD PERFUSION DEVICE

Abstract

Medical devices, as well as methods of treatment and manufacturing such devices, are provided for applying vascular therapy locally within the body vessel. The medical devices include an expandable tubular frame and a sleeve or graft material. The medical devices can be used for local delivery of a therapeutic agent within a body vessel or a tamponade for a lacerated body vessel, while simultaneously allowing perfusion of fluid or blood flow distal of the implanted medical device. The tubular frame of the medical device may have a proximal non-expanding portion and a distal self-expanding support structure. The self-expanding support structure can expand radially outward to urge the graft material to contact the wall of the body vessel. In the expanded configuration, a portion of the device allows fluid flow to continue while the sleeve is against the body vessel wall.

Dependent claims

A blood perfusion device, comprising:

a generally cylindrical self-expanding support structure extending from a proximal end to a distal end;
a non-expanding portion disposed proximally of said self-expanding support structure;
a series of connectors extending from said proximal end of said self-expanding support structure to said non-expanding portion, said connectors allowing said self-expanding support structure to expand while retaining said self-expanding support structure to said non-expanding portion;
a graft material disposed on at least a portion of said self-expanding support structure;
wherein said distal end of said self-expanding support structure forms an unobstructed opening between an inner lumen of said self-expanding support structure and an exterior of the blood perfusion device.

A blood perfusion device, comprising:

a catheter;
a non-expanding portion comprising a tube rigidly connected to said catheter;
a generally cylindrical self-expanding support structure disposed distally of said non-expanding portion and extending from a proximal end to a distal end, said self-expanding support structure comprising longitudinal members extending along substantially the entire length of said self-expanding support structure and angular struts connected to one of said longitudinal members at one end and to another of said longitudinal members at another end, said angular struts forming a series of zig-zag rings from said proximal end to said distal end of said self-expanding support structure;
a series of connectors extending from said proximal end of said self-expanding support structure to said non-expanding portion, said connectors being integrally formed with said self-expanding support structure, said connectors allowing said self-expanding support structure to expand while retaining said self-expanding support structure to said non-expanding portion;
a graft material disposed on at least a portion of said self-expanding support structure;
wherein a first of said angular struts located closest to said non-expanding portion is disposed a distance from said non-expanding portion such that when said self-expanding support structure is fully expanded, said first angular strut does not obstruct said inner lumen of said self-expanding support structure, said inner lumen of said self-expanding support structure only being obstructed at said proximal end by said non-expanding portion, said catheter and said connectors, and said distal end of said self-expanding support structure forming an unobstructed opening between said inner lumen of said self-expanding support structure and an exterior of the blood perfusion device.
