摘要： A visualization catheter includes an elongate shaft, a cap portion, and an offset balloon coupled to the distal end of the shaft. The elongate shaft includes a proximal end, a distal end, and a central axis defined therebetween. The cap portion is coupled to the distal end of the shaft. The cap portion also includes a visualization element and defines an aperture. The offset balloon is coupled to the distal end of the shaft and encapsulates the cap portion. The offset balloon defines a center point offset relative to the central axis of the shaft.

摘要： This document provides endotracheal tube designs with features that can improve the efficacy, patient safety, and efficiency of endobronchial access. For example, this document provides endotracheal tube designs with features for atraumatic passage of the tube's distal tip through the vocal folds. In addition, this document provides endotracheal tubes that have variations in strength and flexibility properties along the length of the tube in an advantageous pattern to enhance the efficacy of the endotracheal tube.

摘要： A direct visualization catheter adapted for transseptal crossing includes at least an outer member, and inner member, a transparent balloon member, and an imaging element. The outer member includes a tubular body extending from a proximal end to a distal end and defines a first lumen there through. The inner member is slidably disposed within the first lumen of the outer member and includes an elongate body with a distal end. The transparent balloon member is coupled between the distal end of the outer member and the distal end of the inner member such that the shape of the transparent balloon member is adjusted by sliding the inner member and the outer member relative to each other. The imaging element is disposed within the balloon member.

摘要： An example medical system for ablating and occluding the left atrial appendage is disclosed. The example system includes a catheter sized and shaped for vascular access and including an elongate body extending between a proximal end and a distal end. A first expandable member may be positioned near the distal end of the elongate body and have a first region configured to permeate a liquid therethrough. A first set of one or more electrodes may be arranged within the first expandable member and may be configured to deliver energy to the tissue region. An occlusive implant may be releasably secured to the distal end of the elongate body.

摘要： A heart valve anchor has a body that includes a distal portion, a distal end, a proximal portion, and a proximal end. The distal end and the proximal end define a longitudinal axis. The body has an expandable portion that includes a first radially expandable portion at the distal portion of the body, a second radially expandable portion at the proximal portion of the body, and a root portion disposed between the first and second radially expandable portions. The body has a first configuration adapted to be housed at least partially within a tissue penetrating device, and a second configuration in which the first and second radially expandable portions are partially or fully expanded such that the anchor engages tissue in a region between the first and second radially expandable portions.

摘要： An illuminated needle device for performing a heart valve repair includes an outer member and an inner member. The outer member includes a body that has a proximal end and a distal end. The body of the outer member defines a lumen therethrough and the distal end of the body includes a needle. The inner member is slidably disposed within the lumen of the outer member. The inner member includes a distal end that has a radiation emitting element. The illuminated needle device is characterized by the outer and inner members together forming a flexible, elongate shaft, and the inner member being configured to emit radiation from the radiation emitting element from a location proximate to the distal end of the outer member.
