TLDR
In this paper, a system for remotely inducing phase transition in a gel is described, which includes a gel capable of volume change in response to an environmental stimulus, a seed material in contact with the gel, and generating a timevarying magnetic or a time-vanging electric or electromagnetic field in the proximity of the gel to produce the environmental stimulus.Abstract:
A system for remotely inducing a phase transition in a gel is provided. The system includes a gel capable of volume change in response to an environmental stimulus, a seed material in contact with the gel, and generating a time-varying magnetic or a time-varying electric or electromagnetic field in the proximity of the gel to produce the environmental stimulus. In a preferred embodiment, the environmental stimulus is temperature.read more

Tissue site markers for in vivo imaging
Fred H. Burbank,Paul Lubock,Michael L. Jones,Richard L. Quick,Frank R. Louw,Stephen A. De Santis +5 more
TL;DR: In this article, the authors proposed directed biopsy site markers and methods of marking a biopsy sites, so that the location of the biopsy cavity is readily visible by conventional imaging methods, particularly by ultrasonic imaging.
Patent
Methods and chemical preparations for time-limited marking of biopsy sites
TL;DR: Detectable markers that may be introduced into a cavity created by removal of a biopsy specimen to mark the location of the biopsy site so that it may be located in a subsequent medical/surgical procedure as mentioned in this paper.
Patent
Biopsy localization method and device
TL;DR: In this article, a de- dehydrated collagen plug is delivered to a soft tissue biopsy site of a patient by an element delivery device, which is used as a therapeutic tool for treatment of the diseased lesion and for hemostatis.
Patent
Porous bioabsorbable implant
TL;DR: The bioabsorbable implant described in this paper is a porous body formed of bioabsorable materials that have an in vivo life span of at least 2 weeks, preferably at least three weeks and not greater than 20 weeks, and no greater than ten weeks.

Inductive heating of ferrimagnetic particles and magnetic fluids: Physical evaluation of their potential for hyperthermia
TL;DR: Experimental results clearly indicate a definite superiority of even non-optimized magnetic fluids over MDP ferrites regarding their specific absorption rate (SAR), and inductive heating by magnetic fluids can improve temperature distributions in critical regions.
