Abstract
A device for percutaneous venous valve repair generally including a catheter and a retractable and extendable member for deploying an object that affixes a portion of a venous valve leaflet to an adjacent vein wall. A related method for percutaneous venous valve repair is revealed to include percutaneously inserting a device as described herein into a peripheral vasculature of a living subject so as to affix at least a portion of a leaflet of a venous valve to an adjacent vein wall.
Claims14
A device for percutaneous venous valve repair comprising:
- (A) a catheter comprising:
- (i) a body having a proximal end and a distal end;
- (ii) at least one lumen, defined by the body of the catheter, that extends between the proximal end and the distal end of the catheter;
- (iii) at least one side port, defined by a distal end portion of the body of the catheter, wherein the at least one side port has an angle in the range of greater than about 0 degrees and less than about 90 degrees, the angle being formed between a transverse axis of the catheter that is orthogonal to a central longitudinal axis of the catheter, and a central axis of the at least one side port, wherein all of the axes share a common intersection point;
- and (iv) at least one expandable member;
- (B) a retractable and extendable member comprising:
- (i) a body having a proximal end and a distal end;
- (ii) a conduit, defined by the body of the retractable and extendable member, that extends between the proximal end and the distal end of the retractable and extendable member;
- (iii) at least one anchor positioned within the conduit;
- and (iv) an anchor deployment mechanism positioned within the conduit so as to cause deployment of the at least one anchor through the conduit and the at least one side port of the catheter when the anchor deployment mechanism is activated;
- wherein the retractable and extendable member is sized and configured to bend and slide through the at least one lumen of the catheter and extend through the at least one side port of the catheter.

- (ii) a conduit, defined by the body of the retractable and extendable member, that extends between the proximal end and the distal end of the retractable and extendable member;
- (iii) at least one anchor positioned within the conduit;
- and (iv) an anchor deployment mechanism positioned within the conduit so as to cause deployment of the at least one anchor through the conduit and the at least one side port of the catheter when the anchor deployment mechanism is activated;
- wherein the retractable and extendable member is sized and configured to bend so as to form an angled portion thereof when the retractable and extendable member is in an extended position and to slide through the lumen of the catheter and extend through the at least one side port of the catheter;
- wherein when the retractable and extendable member is in the extended position, an angle in the range of greater than about 0 degrees and less than about 90 degrees is formed between (i) a transverse axis of the catheter that is orthogonal to a central longitudinal axis of the catheter, and (ii) a central axis of the angled portion of the retractable and extendable member.
