First Claim
Patent Images
1. A catheter, comprising:
- a body defining at least one lumen for passage of blood flow therethrough, said body extending between a distal end positionable in a vascular structure of a patient and a proximal end positionable outside the patient with the distal end in the vascular structure, said body including a wall having adjacent wall portions defining at least one port adjacent said distal end, said at least one port including a first closed condition formed by abutting engagement of said wall portions for preventing blood flow through said port into said lumen, said port including a second open condition formed by radially deforming at least one of said wall portions to open said at least one port and permit blood flow through said port into said lumen.

Abstract
A catheter for providing blood flow includes a wall defining at least one lumen extending between a distal end and a proximal end. The distal end portion of the catheter is deformable to selectively open and close one or more ports in the wall to allow blood flow into or out of the lumen of the catheter.

39. A catheter, comprising:
a body defining at least one lumen for passage of blood flow therethrough, said body extending between a distal end portion positionable in a vascular structure of a patient and a proximal end positionable outside the patient with the distal end portion in the vascular structure, said body including at least one wall having adjacent wall portions defining at least one port in said distal end portion in communication with said at least one lumen, said at least one port including a first closed condition formed by abutting engagement of said wall portions for preventing blood flow through said at least one port, wherein said body includes an enlargement member adjacent said at least one port, said enlargement member having a reduced size configuration when said at least one port is in said closed condition and said enlargement member is enlargeable to an enlarged configuration to deform at least one of said wall portions and place said at least one port in an open condition to permit blood flow through said at least one port. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60)

61. A catheter, comprising:
a body defining at least one lumen for passage of blood flow therethrough, said body extending between a distal end positionable in a vascular structure of a patient and a proximal end positionable outside the patient with the distal end in the vascular structure, said body including a wall having adjacent wall portions defining at least one port adjacent said distal end, said at least one port including a first closed condition formed by abutting engagement of said wall portions with sufficient force to prevent blood flow through said port into said lumen, said port including a second open condition formed by radially deforming at least one of said wall portions in the vascular structure and permit blood flow through said port into said lumen. - View Dependent Claims (62)
