Abstract
Disclosed is an apparatus and method for aiding processes including thrombosis, hemostasis, embolization, anastomotic sealing, and void filling at a treatment site of a patient. The present invention provides for an apparatus and method for polymerizing a material and introducing it to the treatment site. A material is polymerized by various methods, including the application of a catalyst, the application of ultraviolet light, or the application of electromagnetic radiation.
Claims33
A method for aiding processes including thrombosis, hemostasis, embolization, anastomotic sealing, and void filling at a treatment site of a patient through the in vivo mixing and polymerization of a low viscosity material and a low viscosity catalyst, comprising the steps of:
- delivering the material to the treatment site of a patient;
- and
- delivering the catalyst to the treatment site of a patient.
A method for preventing blood from flowing around the outside of a graft by inducing hemostasis via a first material and a second material, comprising the steps of:
- delivering the first material and the second material simultaneously into a perigraft space within a patient;
- and
- mixing the first material and the second material in vivo.
A system for aiding processes including thrombosis, hemostasis, embolization, anastomotic sealing, and void filling at a treatment site of a patient, comprising:
- a catheter having a proximal end and a distal end;
- a connector attached to the proximal-end of the catheter, the connector having a primary port and a side port;
- an energy-curable polymer for injection into the side port;
- a polymer-curing energy source for administering energy into the proximal-end of the catheter;
- and
- an energy guide having a proximal end and a distal end, the energy guide being longitudinally disposed within the catheter.
A method for aiding processes including thrombosis, hemostasis, embolization, anastomotic sealing, and void filling at a treatment site of a patient via a low viscosity polymeric material, comprising the steps of:
- delivering the material to a treatment site of a patient;
- and
- applying energy to the material such that the material polymerizes.
A method for aiding processes including thrombosis, hemostasis, embolization, anastomotic sealing, and void filling at a treatment site of a patient via a low viscosity polymeric material and means for polymerizing the material, comprising the steps of:
- delivering the material to a treatment site of a patient;
- and
- polymerizing the material.
A system for preventing blood from flowing around the outside of a graft, comprising:
- a catheter having a proximal end and a distal end;
- a connector attached to the proximal-end of the catheter, the connector having a primary port and a side port;
- an energy-curable polymer for injection into the side port;
- a polymer-curing energy source for administering energy into the proximal-end of the catheter;
- and
- an energy guide having a proximal end and a distal end, the energy guide being longitudinally disposed within the catheter.
A method for preventing blood from flowing around the outside of a graft via a low viscosity polymeric material, comprising:
- delivering the material to a perigraft space within a patient;
- and
- applying energy to the material such that the material polymerizes.
A method for preventing blood from flowing around the outside of a graft via a low viscosity polymeric material and means to polymerize the material, comprising:
- delivering the material to a perigraft space within a patient;
- polymerizing the material.
A method for sealing anastomotic leaks via a fluid and collagen particles, comprising:
- delivering the fluid and the collagen particles simultaneously to be mixed in vitro;
- and
- dispensing the fluid and collagen particle mixture at an anastomosis site, whereupon the fluid and the collagen particle mixture induces hemostasis.
