Abstract
A prosthetic device for attachment to a vascular structure includes a body with an axial length configured to be adjustable by manipulation of at least one design feature but not materially affected by simple luminal pressurization. The at least one design feature includes at least one of a reducing mechanism or a purse-string provided along at least part of a circumference of the body to actuate reduction of a diameter of the device. The prosthetic device may include a body with an axial length configured to be adjustable and at least one roll-down segment at one end of the body. The at least one roll-down segment may be configured to be facilitated or supported by integrated shape memory materials to maintain the roll-down characteristics.
Claims20
A prosthetic device for attachment to a vascular structure, the device comprising:
- (a) a flexible tube;
- (b) a lumen defined within the flexible tube, wherein the lumen extends from a first opening at a first end to a second opening at a second end;
- (c) an attachment structure at the first end;
- (d) a roll-down segment disposed at the second end, wherein the roll-down segment comprises at least:
- (i) a fully extended configuration, wherein the flexible tube is at full length;
- and
- (ii) a fully collapsed configuration, wherein the flexible tube is at less than 50% of full length;
- and
- (d) a roll-down mechanism operably coupled with the roll-down segment, wherein the roll-down mechanism is configured to urge the roll-down segment between the fully extended configuration and the fully collapsed configuration.
A prosthetic device for attachment to a vascular structure, the device comprising:
- (a) a flexible tube;
- (b) a lumen defined within the flexible tube, wherein the lumen extends from a first opening at a first end to a second opening at a second end;
- (c) a first roll-down segment disposed at the first end, wherein the first roll-down segment comprises at least:
- (i) a first fully extended configuration;
- and
- (ii) a first fully collapsed configuration;
- (d) a first roll-down mechanism operably coupled with the first roll-down segment, wherein the first roll-down mechanism is configured to urge the first roll-down segment between the first fully extended configuration and the first fully collapsed configuration;
- (e) a second roll-down segment disposed at the second end, wherein the roll-down segment comprises at least:
- (i) a second fully extended configuration;
- and
- (ii) a second fully collapsed configuration;
- and
- (f) a second roll-down mechanism operably coupled with the second roll-down segment, wherein the second roll-down mechanism is configured to urge the second roll-down segment between the second fully extended configuration and the second fully collapsed configuration.
A method of attaching a prosthetic device to a vascular structure, the method comprising:
- attaching a first end of a flexible tube to the vascular structure, the flexible tube comprising:
- (a) a lumen defined within the flexible tube;
- (b) a roll-down segment disposed at a second end of the flexible tube, wherein the roll-down segment comprises at least:
- (i) a fully extended configuration, wherein the flexible tube is at full length;
- and
- (ii) a fully collapsed configuration, wherein the flexible tube is at less than 50% of full length;
- and
- (c) a roll-down mechanism operably coupled with the roll-down segment, wherein the roll-down mechanism is configured to urge the roll-down segment between the fully extended configuration and the fully collapsed configuration;
- and
- extending the roll-down segment toward a fully extended configuration.
