A method of treating abnormal tissue within a patient includes positioning a delivery cannula within the patient, the delivery cannula having a first electrode disposed on its distal end; introducing an ablation probe through the cannula and out an open distal end thereof, so that a second ablation electrode carried on the ablation probe contacts abnormal tissue within the patient; conveying ablation energy between the first and second ablation electrodes to ablate the abnormal tissue; and introducing a separate medical element, whether a device or a therapeutic agent, through the cannula before or after the ablation process.

Co-access bipolar ablation probe

A tissue ablation system comprises an ablation source, such as an RF ablation source, configured for generating a common power signal, and a power multiplexor configured for splitting the power signal into first and second power signals, substantially attenuating the second power signal relative to the first power signal to create nominal and attenuated power signals, and sequentially delivering the nominal power signal to each tissue ablation probe, while delivering the attenuated power signal to the remaining ablation probes to which the nominal power signal is currently not delivered.

Method for ablating tissue with multiple ablation probes

A pressure activated valve for controlling the flow of fluid through a medical device, the pressure activated valve comprises a housing including a lumen extending therethrough and a flow control membrane extending across the lumen of the housing to control the flow of fluid through the lumen by opening when a pressure threshold has been reached.

Pressure activated valve with high flow slit

Particles and related methods are disclosed.

Particles

A pressure activated valve for medical applications comprises a housing having a lumen extending therethrough from a proximal end to a distal end thereof and a flow control membrane extending across the lumen to control flow therethrough, the flow control membrane including a mounting portion at which the flow control membrane is coupled to the housing and a lumen occluding portion having a slit extending therethrough so that, when the lumen occluding portion is subjected to a pressure of at least a predetermined threshold level, the lumen occluding portion moves from a closed configuration in which flow through the lumen is prevented to an open configuration in which flow is permitted and wherein a thickness of the mounting portion is greater than a thickness of the lumen occluding portion.

Stacked membrane for pressure actuated valve

A drug-delivery cannula assembly includes a cannula housing adapted for receiving at least one obturator shaft of an obturator assembly therethrough, one or more cannulae, and a supply line coupled to the cannula housing. The cannula housing is adapted for receiving one or more obturator shafts of an obturator assembly therethrough. The one or more cannulae define a longitudinal axis and a passageway aligned with the longitudinal axis. The one or more cannulae each include a proximal end coupled to the cannula housing. The cannula housing is configured to fluidly-couple the one or more cannulae to a source of a drug delivery supply for supplying drugs via the supply line to the one or more cannulae.

Drug-delivery cannula assembly

Embodiments include a method of performing a medical procedure in a patient. The method includes inserting a first working instrument and a second working instrument through an opening in the patient, creating an incision in body tissue inside the patient using at least one of the first and second working instruments, and advancing the second working instrument through the incision to position the second working instrument at a work site inside the patient. The method also includes positioning the first working instrument at the work site without advancing the first working instrument through the incision and performing a procedure at the work site inside the patient using the first and second working instruments.

Method and system for intracavitary and extracavitary procedures

A tissue treatment system comprising a tissue treatment probe to be introduced in a target tissue region, wherein the probe comprises one or more perfusion ports that perfuse electrically conductive fluid to the target tissue region, one or more electrodes that deliver RF energy to the target tissue region to therapeutically treat the tissue, and at least one occlusive body that expands to occlude an anatomical vessel in or near where the probe is located in order to prevent heat generated by the delivery of the RF energy from being lost to mobile bodily fluids.

A compression garment includes a bladder having an inner surface and an outer surface. Wicking material may be present to wick fluid. In another version a removable absorbent material is releasably secured to the bladder.

Compression garment with perspiration relief

An RF ablation device comprises an electrode including a DLC coating deposited on at least a portion thereof. A method of forming an RF ablation device, comprises forming a DLC coating on a portion of a metallic electrode.

Diamond-like carbon electrode coating

Embolization, as well as related particles, compositions, and methods, are disclosed.

Embolization

A pressure actuated valve for controlling the flow of fluid through a medical device, the valve comprises a housing including a lumen extending therethrough and a flow control membrane extending across the lumen to control the flow of fluid through the lumen. The membrane includes a plurality of slits extending therethrough so that, when the membrane is acted upon by a pressure of at least a threshold magnitude, the slits open to permit flow through the lumen and, when not acted upon by a pressure of at least the predetermined magnitude, the slits are maintained closed by a biasing force applied thereto by the membrane to prevent flow through the lumen. Each of the slits extends between end portions thereof along a curve wherein a distance between a first end portion of a first one of the slits and a first end portion of a second one of the slits is a minimum distance between the first and second slits.
