Abstract

A medical device including a body portion configured and dimensioned to be associated with a vessel of a patient and a responsive component associated with the body portion wherein the responsive component is switchable between a first configuration and a second configuration.

Claims

1-46. -46. (canceled)

47. A medical device, comprising:

a body portion configured and dimensioned to be associated with a vessel of a patient; and

a responsive component associated with the body portion wherein the responsive component is switchable between a first configuration and a second configuration.

48. The medical device of claim 47, wherein the first configuration restricts flow through the vessel and the second configuration does not restrict flow through the vessel.

49. The medical device of claim 47, wherein the body portion is configured and dimensioned to receive an external surface of the vessel.

50. The medical device of claim 47, wherein the body portion is configured and dimensioned to be positioned within the vessel.

51. The medical device of claim 47, wherein the vessel is selected from the group consisting of a vas deferens, a fallopian tube, a urethra, and a ureter.

52. The medical device of claim 47, further comprising a controller configured to manipulate the responsive component between the first configuration and the second configuration.

53. The medical device of claim 47, wherein the responsive component is an electrostrictive, magnetostrictive, piezoelectric actuator, or shape-memory material.

54. The medical device of claim 47, wherein the responsive component comprises at least one ferromagnetic particle.

55. The medical device of claim 47, further comprising an indicator operatively associated with the responsive component for indicating whether the responsive component is in the first configuration or the second configuration.

56. The medical device of claim 47, wherein the body portion is substantially cylindrical in shape, and wherein the body portion has an elongate slit formed axially therethrough configured and dimensioned to receive the vessel.

57. The medical device of claim 47, wherein the body portion comprises a material that inhibits tissue growth or adhesion of substances.

58. The medical device of claim 47, wherein the body portion comprises perfluoropolyether.

59. A medical device, comprising:

a body portion configured and dimensioned to be positioned in a vessel of a subject without cutting through the vessel;

a channel defined in the body portion through which the vessel can pass; and

a responsive component associated with the body portion for reversibly closing the channel such that fluid in the vessel is restricted from flowing through the vessel.

60. The medical device of claim 59, wherein the vessel is selected from the group consisting of a vas deferens, a fallopian tube, a urethra, a ureter, a duct, intestine, an artery, and vein.

61. The medical device of claim 59, wherein the responsive component is selected from the group consisting of electrostrictive, magnetostrictive, piezoelectric, shape-memory polymer, and ferromagnetic particle components.

62. The medical device of claim 59, further comprising an indicator operatively associated with the responsive component for indicating an open or closed position of the responsive component.

63. A method of controlling flow through a vessel of a patient, comprising:

associating a medical device with a vessel of a patient wherein the medical device comprises;

a body portion configured and dimensioned to be associated with the vessel of the patient;

a responsive component associated with the body portion for reversibly restricting flow through the vessel; and

controlling the responsive component to restrict or allow flow through the vessel.

64. The method of claim 63, wherein associating the medical device with a vessel comprises implanting the medical device within the vessel.

65. The method of claim 63, wherein associating the medical device with the vessel comprises associating the body portion with an outer diameter of the vessel.
