摘要： Visualization apparatus and methods for transseptal access are described herein where intravascular access across a septal wall is facilitated via devices which provide for direct visual viewing of tissue area. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to the tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid can be pumped into the imaging hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. Any number of therapeutic tools or a guidewire can be passed through the catheter and into the imaging hood for crossing the septal wall and passing the guidewire or instruments therethrough.

摘要： Visualization and treatment of tissue regions via percutaneous access methods and devices are described herein. The system may include a deployment catheter and an expandable imaging hood. In use, the hood may be introduced from outside the patient body through a percutaneous incision and advanced through a subxiphoid pathway, for example, to the heart where entry may be accomplished via an incision through the left atrial appendage. Once within the heart, the hood can be advanced to any chamber to visualize and/or treat tissue by placing the hood against the tissue to be imaged and pumping translucent fluids into the hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. Additionally, any number of therapeutic tools can also be passed through the deployment catheter and into the imaging hood for treating the tissue of interest.

摘要： A device and method of use for securing and coring of tumors within the body during a biopsy of the tumor, specifically breast tumors. An adhesion probe for securing the tumor is described. The probe secures the tumor by piercing the tumor and providing a coolant to the distal tip to cool the tip. The cooled tip adheres to the tumor. A coring instrument adapted for cutting a core sample of the tumor is described. The instrument is provided with a cannula that can cut a core sample of the tumor. The instrument is adapted for use with the probe with the probe fitting within the cannula. The instrument can be used in conjunction with the probe to secure and core a sample of the tumor for biopsy.

摘要： A physiologically acceptable composition comprises a plurality of physiologically acceptable hydrogel particles which have been swollen in a water solution containing a low molecular weight water soluble organic compound, the solution having the ability to swell the particles. The concentration of the organic compound is such that the resulting particles can be inserted, without use of a carrier liquid utilizing a hand driven hypodermic syringe. The swollen hydrogel particles are substantially insoluble in body fluids. The composition is useful for treating urinary tract disorders.

摘要： A self-supporting retractor for holding open an anatomic space for performing endoscopic surgical procedures. The retractor includes a substantially rigid elongate member, having proximal and distal ends, and having an arch shape or “C” cross-section, defining a passage and longitudinal working window along the retractor. The distal end is preferably rounded or streamlined to facilitate insertion along a dissected space with minimized tissue trauma, and may include a hooded portion enclosing the passage at the distal end. The elongate member may include radially cooperating segments or self-retaining edges to maximize the area of the space held open by the retractor. The retractor may include a handle or a pivotable finger grip on the proximal end to manipulate the retractor during use, and/or a curved handle to tent the incision providing access to the dissected space. The retractor may also include a channel member for an endoscope, integrally formed or pivotally attached to the retractor.

摘要： A device for diagnosis and treatment of tumors and lesions within the body. A cannula adapted to apply suction through the lumen of the catheter to the tumor or lesion is described. The lumen has a self sealing valve through which a cryoprobe is inserted while the suction is being applied. The cryoprobe is then inserted into the lesion, and operated to ablate the lesion.
