摘要: An integrated inflation/deflation device provides easy, precise delivery of a small amount of fluid for proper inflation of a low volume surgical balloon and similarly provides easy and fast deflation of the balloon. A preferred embodiment includes a low volume syringe and large syringe mounted together within a housing. A port in the low volume syringe is in communication with the large syringe barrel. The low volume syringe plunger is controlled by a knob disposed on the housing. The large syringe is used to prime the surgical balloon system, including a catheter, and the low volume syringe delivers a precise, predetermined volume of fluid to inflate the balloon. The low volume syringe is also used to deflate the balloon. Preferably, indicia on the housing adjacent the knob direct the required rotation of the knob to deliver the correct volume of fluid to be injected to match a balloon of a given size and shape so that the balloon is properly inflated.

摘要: Disclosed herein is a low profile catheter valve comprising a movable sealer portion positioned within the inflation lumen of a catheter. The sealer portion forms a fluid tight seal with the inflation lumen by firmly contacting the entire circumference of a section of the inflation lumen. The sealer portion may be positioned proximally of a side-access inflation port on the catheter, to establish an unrestricted fluid pathway between the inflation port and an inflatable balloon on the distal end of the catheter. As desired, the clinician may move the sealer portion to a position distal of the inflation port, thereby preventing any fluid from being introduced into or withdrawn from the balloon via the inflation port. Also disclosed herein is an inflation adaptor for moving the sealer portion within the catheter to establish or close the fluid pathway between the inflation port and the inflatable balloon.

摘要: Several improvements are provided in the design of a catheter shaft to reduce costs and improve performance. In one aspect, a small notch is fabricated into a catheter tube by a nonlaser process such as electric discharge machining (EDM) or mechanical grinding. This notch in the catheter tube is necessary for fluid communication between the catheter lumen and a balloon or other element in communication with the tube. Use of a nonlaser process reduces the costs of fabrication while ensuring a high degree of structure integrity. In another aspect, a method is provided to produce a nonuniform polymer coating on a catheter shaft to reduce friction and to maintain a catheter with a low profile. In another aspect, the catheter is provided with a radiopaque marker which is more visible and is more effective at identifying the location of a balloon. The marker is moved closer to a distal balloon by placing it within an adhesive taper adjacent the balloon.

摘要: A device for cutting tissue in a human body may include an elongate, hollow shaft having a proximal portion and a distal portion, a bundle of flexible wires slidably disposed within at least a portion of the shaft and having a proximal end and a distal end, and an actuator coupled with the proximal portion of the shaft and the proximal end of the bundle of wires. The distal end of the bundle may be configured to facilitate cutting of tissue, and the wires of the bundle may be at least partially free to move, relative to one another, to allow a cross-sectional shape of the bundle to differ along a length from the proximal to the distal end. The actuator may be configured to move the wires back and forth through the hollow shaft to cause the distal ends of the wires to cut tissue.

摘要: Described herein are devices, systems and methods for cutting tissue in a patient. In some embodiments, a tissue modification region of a device includes a pair of flexible elongate cutting members extending along the length of the tissue modification region. Each elongate cutting member may be configured to cut a discrete trough into tissue to a depth that is greater than the thickness of the cutting member. In some embodiments, the device includes a spacer. The spacer may be sized and configured to operate in one of two modes. A first mode, in which the spacer is coupled to the cutting members such that it holds a portion of each of the two cutting members a distance from one another, and a second mode, in which at least a portion of the spacer is moved away from a cutting member to allow the cutting members to cut further into tissue.
