Abstract
The disclosure pertains to a device for cutting a suture in a fluid environment which isolates a portion of the suture to be cut within a substantially sealed environment and cuts the suture thermally by using an electrically heated element within the chamber. In another embodiment, the disclosure relates to a vascular sealing system including the suture cutting device and a method of use thereof.
Claims20
A thermal suture cutting device for use with vascular sealing devices comprising:
- a chamber further comprising:
- a first compression bead component defining a first opening therethrough, said first opening being sized and adapted to slidingly receive a suture to be cut;
- a second compression bead component defining a second opening therethrough, said second opening being sized and adapted to slidingly and sealingly receive the suture to be cut;
- an electrically activated heating element within the chamber, said electrically activated heating element being capable of generating a temperature within the chamber greater than the melting temperature of the suture to be cut;
- and
- electrical leads at least partially within the chamber capable of supplying sufficient current to the electrically activated heating element to allow the electrically activated heating element to generate a temperature within the chamber greater than the melting temperature of the suture to be cut;
- a push rod having a proximal end and a distal end, said distal end being attached to the first compression bead component, and one or more lumens extending at least partially between said proximal and distal end;
- and
- a source of electrical current sufficient to allow the electrically activated heating element to generate the temperature within the chamber greater than the melting temperature of the suture to be cut, wherein the source of electrical current is connected to the electrical leads and further wherein the source of electrical current includes a switch capable of interrupting a flow of electrical current, said source of electrical current being associated with the proximal end of the push rod;
- wherein said first compression bead component and second compression bead component cooperate with the suture to be cut to form a substantially fluid tight chamber.
A system for sealing a vascular puncture comprising:
- an anchor deployable adjacent to a vascular puncture;
- a suture attached to the anchor deployable adjacent to the vascular puncture;
- a hemostatic material deployed about the suture;
- and
- a thermal suture cutting device comprising:
- a chamber further comprising:
- a first compression bead component defining a first opening therethrough, said first opening being sized and adapted to slidingly receive a suture to be cut;
- a second compression bead component defining a second opening therethrough, said second opening being sized and adapted to slidingly and sealingly receive the suture to be cut;
- an electrically activated heating element within the chamber, said electrically activated heating element being capable of generating a temperature within the chamber greater than the melting temperature of the suture to be cut;
- and
- electrical leads at least partially within the chamber capable of supplying sufficient current to the electrically activated heating element to allow the electrically activated heating element to generate a temperature within the chamber greater than the melting temperature of the suture to be cut;
- a push rod having a proximal end and a distal end, said distal end being attached to the first compression bead component, and one or more lumens extending at least partially between said proximal and distal end;
- and
- a source of electrical current sufficient to allow the electrically activated heating element to generate the temperature within the chamber greater than the melting temperature of the suture to be cut, wherein the source of electrical current is connected to the electrical leads and further wherein the source of electrical current includes a switch capable of interrupting a flow of electrical current, said source of electrical current being associated with the proximal end of the push rod;
- wherein said first compression bead component and second compression bead component cooperate with the suture to be cut to form a substantially fluid tight chamber.
A method of cutting a suture in a fluid environment comprising:
- passing a suture through a thermal suture cutting device comprising:
- a chamber further comprising:
- a first compression bead component defining a first opening therethrough, said first opening being sized and adapted to slidingly receive the suture;
- a second compression bead component defining a second opening therethrough, said second opening being sized and adapted to slidingly and sealingly receive the suture;
- an electrically activated heating element within the chamber, said electrically activated heating element being capable of generating a temperature within the chamber greater than the melting temperature of the suture;
- and
- electrical leads at least partially within the chamber capable of supplying sufficient current to the electrically activated heating element to allow the electrically activated heating element to generate a temperature within the chamber greater than the melting temperature of the suture;
- a push rod having a proximal end and a distal end, said distal end being attached to the first compression bead component, and one or more lumens extending at least partially between said proximal and distal end;
- and
- a source of electrical current sufficient to allow the electrically activated heating element to generate the temperature within the chamber greater than the melting temperature of the suture, wherein the source of electrical current is connected to the electrical leads and further wherein the source of electrical current includes a switch capable of interrupting a flow of electrical current, said source of electrical current being associated with the proximal end of the push rod;
- wherein said first compression bead component and second compression bead component cooperate with the suture to be cut to form a substantially fluid tight chamber;
- positioning the suture and the thermal suture cutting device in a fluid environment;
- and passing a current through the electrically activated heating element sufficient to allow the electrically activated heating element to generate a temperature within the chamber greater than the melting temperature of the suture.
