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.
Claims19
A vessel clamping pressure device, comprising:
- a pressure applying surface including a surface slit therein on a peripheral edge thereof, wherein the surface slit extends through a thickness of the pressure applying surface and extends from a lateral edge of the pressure applying surface toward a central portion of the pressure applying surface, the pressure applying surface being configured to be applied facing the skin of a patient at a site of a wound closure;
- a support structure coupled to the pressure applying surface, the support structure comprising a support structure slit and a hollow portion, wherein the support structure slit extends completely through a portion of the support structure;
- wherein the support structure slit extends through the support structure from a first end of the support structure coupled to the pressure applying surface to a second end of the support structure opposed to the first end, and wherein the support structure slit is open along a lateral side thereof that extends between the first end and the second end, wherein the pressure applying surface is wider than the support structure such that an outer portion of the surface slit extends laterally beyond the support structure, and wherein the inner portion of the surface slit aligns with the support structure slit;
- and
- a spindle positioned within the hollow portion of the support structure, wherein the spindle is configured to rotate within the hollow portion about a longitudinal axis of the spindle and includes a spindle slit, wherein the spindle slit extends through the spindle laterally relative to the longitudinal axis of the spindle,
- wherein the spindle slit is selectively alignable with the surface slit and the support structure slit by rotation to a first rotation angle of the spindle to allow insertion of suture threads into the surface slit, the support structure slit, and the spindle slit, and misalignable by rotation to a second rotation angle of the spindle to bind the suture threads between the support structure and the spindle to maintain tension on the suture threads.

A method of closing an incision in a vascular vessel in a patient, comprising:
- closing the incision in the vascular vessel using suture threads, and extending the suture threads from an entrance incision in the patient;
- inserting a lateral side of the suture threads extending from the entrance incision through slits in a vessel clamping pressure device comprising a pressure applying surface, a spindle and a support structure, wherein the pressure applying surface includes a surface slit that extends through a thickness of the pressure applying surface and extends from a lateral edge of the pressure applying surface toward a central portion of the pressure applying surface, wherein the support structure includes a support structure slit that extends through the support structure from a first end of the support structure coupled to the pressure applying surface to a second end of the support structure opposed to the first end, and wherein the support structure slit is open along a lateral side thereof that extends between the first end and the second end, wherein the pressure applying surface is wider than the support structure such that an outer portion of the surface slit extends laterally beyond the support structure, and wherein an inner portion of the surface slit aligns with the support structure slit, and wherein inserting the lateral side of the suture threads includes inserting the lateral side through the surface slit and the support structure slit;
- tensioning the suture threads between the vessel clamping pressure device and the patient;
- turning the spindle about a longitudinal axis of the spindle to bind the suture threads between the spindle and the support structure of the vessel clamping pressure device, wherein the spindle includes a spindle slit that extends through the spindle laterally relative to the longitudinal axis of the spindle, and wherein turning the spindle rotates the spindle slit from a first rotation angle at which the spindle slit is aligned with the surface slit and the support structure slit to a second rotation angle at which the spindle slit is misaligned with the support structure slit to bind the suture threads;
- 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 by turning the spindle to release the suture threads and cutting the sutures threads below the vessel clamping pressure device.

A vessel clamping pressure device, comprising:
- a support structure comprising:
- a support structure body that includes a support structure slit, wherein the support structure slit extends through the support structure body from a first end of the support structure body to a second end of the support structure body opposed to the first end, and wherein the support structure slit is open along a lateral side thereof that extends between the first end and the second end;
- a pressure applying surface at the first end of the support structure body, wherein the pressure applying surface includes a surface slit that extends through a thickness of the pressure applying surface and extends from a lateral edge of the pressure applying surface toward a central portion of the pressure applying surface, wherein the surface slit is at least partially aligned with the support structure slit, wherein the pressure applying surface is wider than the support structure body such that an outer portion of the pressure applying surface extends beyond the support structure body, and wherein at least the outer portion of the pressure applying surface is transparent;
- and
- a hollow portion extending through a side of the support structure other than a first side on which the pressure applying surface is connected thereto or a second side that is opposed to the first side;
- and
- a spindle positioned within the hollow portion of the support structure, wherein the spindle is configured to rotate within the hollow portion about a longitudinal axis of the spindle between at least a first rotational position and a second rotational position and includes a spindle slit therein, wherein the spindle slit extends through the spindle laterally relative to the longitudinal axis of the spindle, wherein in the first rotational position the support structure slit and spindle slit are aligned to receive lateral insertion of a portion of suture thread, and wherein in the second rotational position the spindle slit is not aligned with the support structure slit such that rotating the spindle from the first rotational position to the second rotational position will bind the portion of the suture thread that is inserted in the spindle slit between the spindle and the support structure.
