Provided herein are systems, devices, assemblies, and methods for localization of a tag in a tissue of a patient. For example, provided herein are systems, devices, and methods employing a detection component that is attached to or integrated with a surgical device, where the detection component detects a signal from a tag in a patient, where the tag is activated by remote introduction of a magnetic field.
摘要:
A self-closing device for implantation within a patient's body includes base material including an inner surface area for securing the base material to a tissue structure, and a plurality of support elements surrounding or embedded in the base material. The support elements are separable laterally within a plane of the base material to accommodate creating an opening through the base material for receiving one or more instruments through the base material, and biased to return laterally towards a relaxed state for self-closing the opening after removing the one or more instruments. The device may be provided as a patch or integrally attached to a tubular graft or in various shapes.
摘要:
A system, method and devices are described that use fiducials to help localize and treat a region of tissue. The fiducials are cooperative with at least one imaging modality, but may also be located using a second physical method to determine the proximity of a seeker probe to the fiducials. The fiducials may also contain electronics and subsystems to enable them to be used to deliver therapy to the region of tissue near the fiducial.
摘要:
According to various embodiments, a method and system to obtain access to a blood vessel underneath a skin layer that may preserve lifespan of the blood vessel and reduce executional skill variability may be provided. The method includes placing a guiding portion between the blood vessel and the skin layer; and configuring the guiding portion to receive and guide a needle to reach the same location of the blood vessel repeatedly and consistently; and forming a resultant scarred track between the blood vessel and the skin layer as the guiding portion is resorbed over time. The system includes a vascular access device configurable to first possess strength to penetrate through a tissue layer, subsequently possess flexibility to conform to the surrounding tissue beneath the tissue layer; and a guiding portion which may be resorbable, wherein the inlet includes a larger diameter compared to the outlet.
摘要:
A method for treating a site within a patient from which tissue has been removed includes providing at least one press-formed marker body formed of polysaccharide and a suitable binder; and placing the at least one of the press-formed marker body within the site where tissue has been removed so as to provide hemostasis therein.
摘要:
A remotely imageable marker system includes a tubular delivery member having an inner lumen and a plurality of marker members. Each marker member of the plurality of marker members comprises a bioabsorbable polysaccharide in sufficient amount to exhibit hemostatic properties and a binder. The plurality of marker members is disposed within the inner lumen of the tubular delivery member.
