Tissue access devices and methods of using the same are disclosed. The devices can have a sensor configured to occlude a flow path by deflecting a membrane into the flow path when the devices become dislodged from tissue. The sensor can be configured to partially or fully occlude the flow path. The sensor can have a spring. The spring can be biased to move the sensor from a sensor first configuration to a sensor second configuration when a force applied by the sensor first surface against a non-sensor surface changes from a first force to a second force less than the first force. The membrane can be deflected into the flow path when the sensor is in the sensor second configuration.

Needle safety systems

An implant may include a frame and a cover to facilitate endoluminal vessel occlusion, selective release of embolic material toward a target region, and/or endoluminal stenting. The frame of the implant provides radial expansion properties to secure the cover within a body vessel. The cover and/or the frame can occlude flow of a fluid through the body vessel.

Implantable luminal devices

An occlusion system can include an expandable implant that can be delivered to a bodily lumen. The implant can be carried on an engagement section of a catheter used in the system. The implant can be assembled onto the catheter by coupling a cover member of the implant with a support member of the implant. When assembled, the system can be advantageously configured to have a low delivery profile to facilitate delivery through catheters having a size of less than 7 Fr, and in some cases, less than 6 Fr.

Bodily lumen occlusion

An occlusion device delivery system can deliver an implant using a catheter. A distal section of the catheter has proximal and distal apertures extending through a wall of the catheter. The implant can be wound about the distal section and secured to the catheter via an engagement mechanism. The implant has a proximal segment that curves inwardly across the proximal aperture and a distal segment that curves inwardly across the distal aperture. The engagement mechanism engages the proximal and distal segments within their respective apertures to secure the implant to the catheter.

Blood vessel occlusion

A system for implanting a catheter in a urethra. The system includes a catheter having a valve disposed at a distal portion of the catheter. The valve may be operable in response to an external magnetic field. The system also includes a tool having a tip member extending into an opening at the distal portion of the catheter to couple the tool to the catheter. the system also includes an element extending from the tool. The catheter has an internal path that provides a conduit for the element to be extended through the valve to engage a proximal portion of the catheter. The tool is adapted use the element to stress the catheter and stiffen the catheter along the length of the catheter. Stiffening the catheter facilitates implantation of the catheter in the urethra by enabling pull forces, push forces, and torque forces to be transmitted from the tool through the catheter to the proximal portion of the catheter without undue stress on the urethra. The element is extendible and retractable to position the catheter between stressed and relaxed states while maintaining engagement to the catheter proximal portion. The tool, element and tip member are removable from the catheter after implantation of the catheter in the urethra.

System and method for implanting a catheter

A device for delivering an expandable member to a luminal structure in a patient is described. In some embodiments, the device has a carrier member, with a carrier lumen extending at least partially therethrough. The device can have an elongate member that extends through the carrier lumen across a first notch in the carrier member. The device can have an expandable member that expands within and engages the luminal structure, can be carried by the carrier member, and has a first portion that fits within the first notch. When the elongate member extends through the carrier lumen and across the first notch, the elongate member secures the first portion to the carrier member. The elongate member is configured to move axially through the carrier lumen such that the elongate member permits release of the first portion from the carrier member and expansion of at least part of the expandable member.

Expandable device delivery

An occlusion device delivery system can deliver an expandable coiled implant using a catheter. A distal portion of the catheter has proximal and distal apertures extending through a wall of the catheter. The expandable coiled implant is wound about the distal portion and has a proximal section that extends within the proximal aperture and a distal section that can extend radially within the distal aperture. Further, the system has an elongate member that extends through the lumen and engages and radially restrains the at least one of the proximal and distal sections within its respective aperture while engaged with the member.

An occlusion device delivery system and methods are provided in which an expandable coiled implant can be delivered using the delivery system. The system can comprise a catheter having a lumen extending between distal and proximal portions. The distal portion can have proximal and distal apertures extending through a wall of the catheter. The expandable coiled implant, which can be wound about the distal portion, can have a proximal section that extends within the proximal aperture and a distal section that can extend radially within the distal aperture. Further, the system can comprise an elongate member that extends through the lumen and engages and radially restrains the at least one of the proximal and distal sections within its respective aperture while engaged with the member.

Methods and apparatuses for blood vessel occlusion

Delivery catheters and systems are adapted for delivering multiple discreet prostheses in body lumens. An exemplary delivery catheter comprises a sheath, a pusher for moving the prostheses relative to the sheath, and a valve member for selectively retaining the prostheses in the sheath. For balloon expandable stents, an elongated shaft and an expandable member are slidably disposed in the sheath, and the prostheses are positionable on the expandable member for deployment in the body lumen. The valve member allows a selected number of prostheses to be deployed from the sheath while retaining other prostheses within the sheath.

Delivery catheter having active engagement mechanism for prosthesis

A molding machine for molding microparts containing between 0.001 to 3.5 cubic centimeters of plastic shot volume includes a plasticizing portion operatively connected to an injection portion and a mold portion. A valve member is provided to open and close the connection between the plasticizing portion and the injection portion. A linear motor member is associated with the injection portion to permit molding times of 0.01 seconds at pressures up to about 100,000 psi during injection of the molten plastic into the mold portion.
