摘要:
A method for mapping a lymphatic system following a cavity generating procedure, may include a step of providing a post-biopsy cavity treatment implant, the implant including a collagenous matrix having a non-uniform cross-linking density that is configured to cause the implant to swell non-uniformly when placed within an aqueous environment, the implant including a dye or a pigment contained therein. The provided post-biopsy cavity treatment implant may then be implanted into the cavity and the cavity closed. The dye/pigment may then be caused to be released from the implant and to propagate through the lymphatic system. The propagated dye/pigment may then be visualized in the lymphatic system using a selected visualization mode.

A method of removing breast tissue may include a step of providing a tissue cutting device having an elongate cutting element coupled to a shaft, in which the cutting element is movable between a bowed position and a retracted position. A deployed part of the cutting element may lie outside the shaft when in the bowed position, and the deployed part of the cutting element may have a cutting side which penetrates the tissue as the shaft is rotated. The tissue cutting device may be introduced into the breast and a power source may be coupled to the elongate cutting element. The elongate cutting element may be moved to the bowed position so that the deployed part of the cutting element lies outside the shaft. Energy may be prevented from being transmitted from a portion of the deployed part of the cutting element for cutting to the tissue while the elongate cutting element is in the bowed position. The cutting device may be rotated so that the cutting side of the bowed cutting element penetrates the breast tissue to cut the breast tissue for removal.
摘要:
Devices and methods for collecting or cutting and collecting a specimen from a mass of tissue within a patient. The device may include a specimen collection assembly including a flexible membrane that isolates collected specimen from the surrounding tissue. The collection device may also include structures that draw the collected specimen toward the shaft and/or otherwise ease the insertion and retraction of the device and the collected specimen from the patient through a small incision.
摘要:
The device is used to remove tissue from a patient and to also place a marker in the patient. The device has an opening through which tissue enters the device. The tissue which enters the opening is cut and the tissue is removed. The device may be used a number of times to remove a number of tissue masses. The device also includes a marker which the user may release in the patient at the desired time.
摘要:
The present short-term post surgical cavity treatment device includes a first portion including an inflatable balloon at the distal end of the device and a second portion coupled to the first portion that defines at least an inflation lumen and a treatment lumen. The second portion may be configured such that the inflation lumen enables inflation of the inflatable balloon. An inflation port may be coupled to the inflation lumen to enable introduction of a fluid or gas into the inflatable balloon. The second portion of the present device may be configured such that the treatment lumen enables various short-term cavity treatments, therapies and methods within the cavity in conjunction with the inflatable balloon. The balloon may be configured so as to inflate in a predetermined shape. This predetermined shape may be configured so as to substantially match the shape of the cavity within the tissue. The inflatable balloon may also be configured, treated, coated or otherwise configured so as to carry out a beneficial function on the tissue walls defining the post surgical cavity.

Methods and percutaneous devices for assessing, and treating patients having sympathetically mediated disease, involving augmented peripheral chemoreflex and heightened sympathetic tone by reducing chemosensor input to the nervous system via percutaneous carotid body ablation.
摘要:
A system has been developed for injecting a biodegradable pericardial constraint including: a biodegradable viscoelastic substance (BES); an external injection container for the BES; a cannula having a distal section adapted to be inserted into a pericardial sac of a mammalian heart and a proximal section connectable to the external injection container; wherein BES from the injection container is injected into the pericardial sac through the cannula.

摘要:
A method to constrain a heart including the steps of: injecting a biopolymer into a pericardial space of the heart; inducing intramolecular or intermolecular interactions in the biopolymer in the pericardial space to modify physical properties of the biopolymer in the pericardial space, and constraining the heart with the modified biopolymer in the pericardial space.
