The present disclosure falls into the field of medical apparatus, and discloses a radiation therapy apparatus and a beam imaging method, wherein the radiation therapy apparatus includes: a treatment head including multiple radiation sources distributed on one side of a target region, radiation beams emitted by the multiple radiation sources intersecting in the target region, and a lesion being located within the target region; a beam detector used for receiving a radiation beams passing through the lesion and emitted by the radiation sources to acquire projection data of each radiation beam passing through the lesion, and generating a slice image of the lesion according to the acquired projection data; and a processor used for constructing an image of the lesion in the target region based on the slice image generated by the beam detector. The radiation therapy apparatus of the present disclosure can implement a three-dimensional imaging process in real time, the treatment head of the beam therapy apparatus can be directly used for tracking tumors, and the human body can be positioned according to the reconstructed three-dimensional image before surgery.

In the present disclosure, embodiments of dual-stage syringes are disclosed along with delivery systems incorporating the dual-stage syringes. Embodiments of the dual-stage syringes described herein include sleeved dual-stage syringes, turn-key dual-stage syringes and dual-stage syringes including one or more one-way valves.

A surgical implant includes a biocompatible member configured for securement to an underlying target surgical site and a radiation source integrated into or onto the biocompatible member. The surgical implant may be one of a clip, pin, or coil and the radiation source includes at least one brachytherapy capsule, or other radioactive material incorporated therein or provided thereon. The radioactive material provides a dose of radiation to the target surgical site. The surgical implant may also be formed from titanium, stainless steel or polymers. A surgical applier is provided for allowing a surgeon to apply the implant to a patient's tissue.

An end effector for a surgical fastening device is provided. The end effector includes a body defining a longitudinal axis, one or more fasteners, an anvil, and a pusher. Each fastener has an unformed configuration and a formed configuration. Each fastener includes first and second arms that extend in opposite directions. The first arm has first and second elbow segments. The first elbow segment is configured to bend as the fastener is formed. The second elbow segment is configured to remain unbent as the fastener is formed. The pusher is configured to advance the fastener distally through the body and into engagement with the anvil to form the fastener against the anvil.

Systems and methods for shuttle mode radiation delivery are described herein. One method for radiation delivery comprises moving the patient platform through the patient treatment region multiple times during a treatment session. This may be referred to as patient platform or couch shuttling (i.e., couch shuttle mode). Another method for radiation delivery comprises moving the therapeutic radiation source jaw across a range of positions during a treatment session. The jaw may move across the same range of positions multiple times during a treatment session. This may be referred to as jaw shuttling (i.e., jaw shuttle mode). Some methods combine couch shuttle mode and jaw shuttle mode. Methods of dynamic or pipelined normalization are also described.

In the present disclosure, embodiments include flaring tip microcatheters, methods of deploying flaring tip microcatheters, and embolization treatment methods. The flaring tip microcatheter may include a hollow shaft having a shaft lumen defined therein, a core disposed within the shaft lumen, and a tip including at least two petals affixed to a distal end of the core, the at least two petals including at least two wires wherein the core is hollow and defines a core lumen. The at least two wires may be configured to pull the at least two petals to form a flared configuration of the tip. The flared configuration of the tip may allow for laminar flow of a therapeutic agent distally from the tip.

Presented systems and methods facilitate efficient and effective generation and delivery of radiation. In one embodiment, an accelerator system includes a particle source, an acceleration portion, a high intensity target, and a target location control component. The particle source is configured to generate charged particles. The acceleration portion is configured to accelerate the charged particles. The high intensity target is configured to generate Bremsstrahlung radiation in response to impact by the charged particles. The target location control component configured to change the location of charged particle impacts on the high intensity target. In one exemplary implementation the change of location of charged particle impact is based on thermal diffusion and said location of charged particle impacts is moved at a rate greater than a rate of diffusion of detrimental heat impacts on the high intensity target.

A method of stapling tissue includes clamping tissue between a cartridge assembly and an anvil assembly of a loading unit, firing the loading unit such that the fasteners secured in the cartridge assembly pass through a body portion of a first buttress that is positioned between the clamped tissue and one of the cartridge assembly or the anvil assembly, trimming a first portion of the first buttress that is adjacent a first edge of the tissue, and removing the first portion of the first buttress from a surgical site. The first buttress capturing fasteners that are fired from a portion of the cartridge assembly which extends beyond the tissue. The first portion of the first buttress including at least one remnant fastener.

A surgical implant is provided comprising a biocompatible member configured for securement to an underlying target surgical site and a radiation source integrated into or onto the biocompatible member. The surgical implant may be one of a clip, pin, or coil and the radiation source includes at least one brachytherapy capsule, or other radioactive material incorporated therein or provided thereon. The radioactive material provides a dose of radiation to the target surgical site. The surgical implant may also be formed from titanium, stainless steel or polymers. A surgical applier is provided for allowing a surgeon to apply the implant to a patient's tissue.

A method for treating a tumor, comprising identifying a tumor as a breast cancer tumor and implanting in the tumor identified as a breast cancer tumor, at least one diffusing alpha-emitter radiation therapy (DaRT) source (21) with a suitable radon release rate and for a given duration, such that the source (21) provides during the given duration a cumulated activity of released radon between 3.5 Mega becquerel (MBq) hour and 9 MBq hour, per centimeter length.
