Abstract
A system and method for delivering a pledget of hemostasis promoting material to a blood vessel puncture to facilitate hemostasis, having an introducer sheath having an inner diameter and an outer diameter, a control tip coupled to the introducer sheath, and a self-expandable member disposed around a portion of the control tip to control blood flow at the blood vessel puncture.
Claims25
A system for delivering a pledget of hemostasis promoting material to a blood vessel puncture to facilitate hemostasis, the system comprising:
- an introducer sheath having an inner diameter and an outer diameter;
- a control tip coupled to said introducer sheath, the control tip including an enlarged distal end;
- and,
- a self-expandable member disposed around the distal end of said control tip to control blood flow at the blood vessel puncture, the self-expandable member having a proximal end and a distal end.
A system for delivering a pledget of hemostasis promoting material to a blood vessel puncture to facilitate hemostasis, the system comprising:
- an introducer sheath having an inner diameter and an outer diameter;
- a control tip coupled to said introducer sheath and including a pressure port;
- and,
- a self-expandable member disposed around a portion of said control tip to control blood flow at the blood vessel puncture, the self-expandable member having a proximal end and a distal end.
A system for delivering a pledget of hemostasis promoting material to a blood vessel puncture to facilitate hemostasis, the system comprising:
- an introducer sheath having an inner diameter and an outer diameter;
- a control tip coupled to said introducer sheath;
- and,
- a self-expandable member disposed around a portion of said control tip to control blood flow at the blood vessel puncture, the self-expandable member having a proximal end and a distal end wherein said self-expandable member has a first wall thickness at the proximal end and a second wall thickness at the distal end.
A system for delivering a pledget of hemostasis promoting material to a blood vessel puncture to facilitate hemostasis, the system comprising:
- an introducer sheath having an inner diameter and an outer diameter;
- a control tip coupled to said introducer sheath;
- and,
- a self-expandable member disposed around a portion of said control tip to control blood flow at the blood vessel puncture, the self-expandable member having a proximal end and a distal end;
- wherein an airtight chamber is formed between the self-expandable member and the control tip.
A method for sealing a puncture in the wall of a blood vessel, comprising:
- inserting a flexible seal into an interior of the blood vessel, the flexible seal having an air-tight chamber;
- positioning a distal portion of the air-tight chamber within the interior of the blood vessel;
- and
- positioning aproximal portion of the air tight chamber outside the blood vessel vesicle interior.
