摘要： A marker delivery device includes an elongated delivery cannula which has a distal end section, an inner lumen and a discharge opening in the distal end section in communication with the inner lumen. At least one elongated fibrous marker body is slidably disposed within the inner lumen of the elongated delivery cannula. The at least one elongated fibrous marker body includes a plurality of bioabsorbable polymeric strands. The strands are compressed to a compressed configuration and bound together in the compressed configuration with a polymer binding agent prior to insertion into the elongated delivery cannula. A releasable plug is disposed within a distal portion of the inner lumen and distal to the at least one elongated fibrous marker body so as to at least partially occlude the discharge opening in the distal end section.

摘要： The disclosure is directed to catheter devices and methods for controlled application of irradiation to tissue adjacent a body site, such as cavity after removal of tissue, e.g. cancer. The catheter device includes an inflatable balloon having at least two layers. The inflatable balloon has an expansion of more than 25% and less than 200% when inflated from the un-inflated condition to a turgid condition, preferably more than 50% and less than 150%. In the turgid condition the polymeric material(s) of the balloon layers are at or near the elastic limit of the balloon layer material. The balloon may contain or be formed of or be coated with radiopaque material to facilitate positional or symmetry verification.

摘要： A medical device system and method provide an RF electrosurgical generator coupled to an electrosurgical electrode via a patient box disposed in close proximity to the patient. An RF signal is delivered from the generator to the patient box where signal power is increased and the RF signal delivered to the electrosurgical electrode. The patient box is coupled to the electrosurgical electrode by a short cable capable of carrying an HV, high frequency 5 MHz signal without leakage. An electrical characteristic associated with the electrosurgical electrode is monitored and a desired RF power output and duty cycle maintained by adjusting DC input voltage applied to an RF amplifier, responsive to the monitoring. The system determines when the electrosurgical cutting electrode has started cutting and switches from a start mode to a run mode having a different RF duty cycle and a reduced RF power output controlled by a servo system.

摘要： A device for encapsulating tissue specimens includes a wand assembly, a sheath, and a guide assembly. The guide assembly pulls, draws, or otherwise moves the sheath about the tissue specimen. The wand assembly is disposed proximate to the tissue specimen, typically either adjacent or through the specimen. In an aspect of the encapsulating device, the guide assembly has sheath deployment members that are disposed about the tissue specimen. The sheath, which is attached to ends of the sheath deployment members and the wand assembly, is drawn over the tissue specimen as the sheath deployment members are pushed or pulled. The guide assembly is an arm or a housing that rotates about the tissue specimen. The sheath, which is secured at one end to the guide assembly and at another end to the wand assembly, is drawn over the tissue specimen as the guide assembly rotates.

摘要： An intracorporeal marker includes a fibrous unitary marker body having bioabsorbable fibers compressed into a compressed configuration, and bound in the compressed configuration by a polymer binding agent. The intracorporeal marker may be incorporated into an intracorporeal marker delivery device having a delivery cannula which has a distal tip, an inner lumen and a discharge opening in communication with the inner lumen. The compression and binding occur prior to insertion of the fibrous unitary marker body into the inner lumen of the delivery cannula. The fibrous unitary marker body is slidably disposed within and pushable through the inner lumen of the elongated delivery cannula proximal to the discharge opening.
