Abstract
Various embodiments include a vessel clamping pressure device that is configured to receive suture threads extending from the closure of a vascular vessel of a patient, and maintaining tension on suture threads between the patient and the vessel clamping pressure device to apply pressure to the patient so as to apply a clamping pressure to the vascular vessel to facilitate clotting.
Claims11
A method of closing an incision in a vascular vessel in a patient, comprising:
- closing the incision in the vascular vessel using sutures threads, and extending the suture threads from an entrance incision in the patient;
- inserting an extent of the suture threads extending from the entrance incision into a vessel clamping pressure device, wherein the vessel clamping pressure device comprises:
- a pressure applying surface with a surface slit, wherein the pressure applying surface is configured to contact the skin of the patient and is formed with a thickness extending in a first direction configured to extend directly away from the skin of the patient when in contact therewith, wherein the surface slit extends through the thickness of the pressure applying surface in the first direction, wherein the surface slit also extends from a lateral edge of the pressure applying surface toward a central portion of the pressure applying surface in a second direction lateral to the first direction,
- a central shaft with a shaft slit, wherein the central shaft extends away from the pressure applying surface in the first direction from a first side of the central shaft that connects to the pressure applying surface to a second side of the central shaft that is opposed to the first side, wherein the shaft slit extends through the central shaft from the first side to the second side and is open along a lateral side of the central shaft that extends between the first side and the second side, and
- a spindle located within the central shaft, the spindle including a spindle slit,
- wherein inserting the extent of the suture threads comprises inserting the extent of the suture threads to extend through the surface slit, shaft slit, and spindle slit;
- tensioning the suture threads between the vessel clamping pressure device and the patient;
- leaving the vessel clamping pressure device on the entrance incision for a clotting period;
- and
- after the clotting period, releasing tension on the suture threads and cutting the sutures threads below the vessel clamping pressure device.

A surgical vessel closing pressure device, comprising:
- a pressure applying surface configured to contact a patient's skin or intermediate materials on the patient's skin at an incision site, wherein the pressure applying surface is formed with a thickness extending in a first direction configured to extend directly away from the skin of the patient when in contact therewith, wherein the pressure applying surface includes a first slit extending therethrough, wherein the first slit extends through the thickness of the pressure applying surface in the first direction, wherein the first slit also extends from a lateral edge of the pressure applying surface toward a central portion of the pressure applying surface in a second direction lateral to the first direction;
- a central shaft coupled to the pressure applying surface, wherein the central shaft extends away from the pressure applying surface in the first direction from a first side of the central shaft that connects to the pressure applying surface to a second side of the central shaft that is opposed to the first side, wherein the central shaft includes a second slit extending therethrough, wherein the second slit extends through the central shaft from the first side to the second side and is open along a lateral side of the central shaft that extends between the first side and the second side;
- and
- a spindle adjustably located within the central shaft and rotatable about a longitudinal axis of the spindle, the spindle including a third slit extending through the spindle laterally relative to the longitudinal axis,
- wherein the first, second, and third slits are configured to be selectively alignable and misalignable by rotation of the spindle to respectively allow insertion of suture threads into the first, second, and third slits and bind the suture threads by adjusting an orientation of the spindle to maintain tension between the device and a vascular vessel.
