In various embodiments, a radiation therapy method can include loading a planning image of a target in a human. In addition, the position of the target can be monitored. A computation can be made of an occurrence of substantial alignment between the position of the target and the target of the planning image. Furthermore, after the computing, a beam of radiation is triggered to deliver a dosage to the target in a short period of time (e.g., less than a second).

A non-linear ablation device includes two opposing surfaces, which are associated with two overlying and separate compartments. A first compartment of the two overlying and separate compartments is configured to emit or resorb energy. A second compartment of the two overlying and separate compartments is configured to either resorb or emit energy to oppose a direction of energy transfer of the first compartment. Other embodiments of the non-linear ablation device are further disclosed.

The present invention provides a human tissue radiation protector with auxiliary method of radiotherapy, wherein said human tissue radiation protector comprises an interconnected expander, a syringe and a marker set onto the expander; said marker is made of radiopaque materials, which could assist the expander in positioning; as well as multiple radiation dosage detector capable of measurement the radiation dosage at different positions of the expander; said method allows to place the expander of the human tissue radiation protector between the tumor and nearby human tissues or organs so as to separate them, and assist the expander in positioning via the marker and measurement the radiation dosage via the radiation dosage detector.

A medical device for use during radiation therapy may include a longitudinal body configured to be positioned within a urethra. The longitudinal body may include a lumen, a distal end, and a proximal end. A first balloon may be coupled to a distal portion of the longitudinal body and fluidly connected to a first port at the proximal end of the longitudinal body. A second balloon may be positioned between the first balloon and the proximal end of the longitudinal body and fluidly connected to a second port at the proximal end of the longitudinal body.

An ocular protection device and treatment methods are disclosed. The device has a corneal shield with an attached handle. The handle may be used to move the corneal shield to better protect the eye from various treatment modalities. The handle may also be used to place tension on the eyelid to counteract the forces imposed by a treatment handpiece. A procedure for treating the eye is disclosed where multiple passes with a treatment handpiece cause a gradual increase in the temperature of an eyelid up to a treatment temperature. Once the treatment temperature has been met, occlusions in the Meibomian glands of the eyelid may be expressed. The procedure may be repeated recursively until a desired level of expression has been achieved.

A wrappable sterile radiation shield drape, a wrappable sterile radiation shield drape in combination with a radiation shield, and a method of providing a sterile surface about a suspended radiation shield is provided. The drape includes a flexible wall having a sterilized outer surface. The wall has opposite side edges extending between upper and lower ends and an upper fastener adjacent its upper end. The upper fastener is configured to releasably fix the upper end of the wall relative to the radiation shield. The wall further includes an edge fastener adjacent at least one of its side edges. The edge fastener is configured to releasably maintain the wall in a wrapped configuration about the radiation shield. The wall further includes at least one flap attached adjacent the upper end, wherein the flap includes a pocket configured to receive a shoulder extension portion of the radiation shield.

A device for protecting the esophagus during a surgical ablation procedure within a heart of a patient, the device comprising a catheter having a sensor and positionable within an esophagus of a patient. An indicator is in communication with the sensor to indicate if a parameter exceeds a predetermined value, thereby indicating to the user to reduce or cease the ablation procedure within the heart of the patient.

Apparatus and techniques for blocking radiation in a medical environment are described. In one or more embodiments, a lock-block shield device includes a base that is configured to adhesively couple to an object associated with a patient. In some embodiments, the base includes a lock mechanism for securing a work piece that has a generally tubular shape. A shield that is configured to at least partially block transmission of radiation can be coupled to the base in a releasable manner. For example, a clasp is used to secure the base and shield together. In embodiments, a ball and socket joint couples the shield and base to permit, for example, the shield to pivot and articulate with respect to the base.
