| 20090064492 | METHOD OF MANUFACTURING RF ABLATION PROBE WITH UNIBODY ELECTRODE ELEMENT - An ablation probe and method of manufacturing the ablation probe are provided. The probe comprises a probe shaft and a unibody electrode element. The unibody electrode element comprises a common electrode base located at the distal end of the shaft, and a plurality of electrode tines distally extending from the electrode base. The electrode element may be created by forming divisions (such as slits or slots) from a first end of an electrically conductive elongate member towards an opposing second end of the elongate member. Alternatively, the divisions can be formed from a first end of an electrically conductive sheet towards an opposing second end of the sheet, and then bent or rolled to form the elongate member. In either case, the common electrode base can either be separately mounted to a probe shaft, or the probe shaft can be formed from the elongate member, in which case, the electrode base will be integrated with the probe shaft as a unibody structure. The electrode tines can be optionally shaped, e.g., to proximally evert. | 03-12-2009 |
| 20090131826 | OBTAINING A TISSUE SAMPLE - A device with a sampling portion configured to engage, sever, and remove tissue from a body can be used to obtain one or more tissue samples from the body. The device can be used to obtain multiple tissue samples simultaneously. | 05-21-2009 |
| 20090157060 | Multi-functional medical device - An embodiment of a medical device includes a proximal handle, a distal end effector, an elongate member connecting the end effector to the handle, and a sheath enclosing at least a portion of the elongate member. The handle may include a first mechanism coupled to one of the sheath and the elongate member to move the sheath relative to the elongate member, a second mechanism coupled to the elongate member to rotate the elongate member relative to the handle, and a locking mechanism coupled to the first mechanism to hold the first mechanism in a default position. Embodiments also include methods of positioning the medical device to perform a medical procedure. | 06-18-2009 |
| 20090187254 | UROLOGICAL MEDICAL DEVICES FOR RELEASE OF UROLOGICALLY BENEFICIAL AGENTS - In one aspect, the present invention provides implantable or insertable urological medical devices, which are adapted to release one or more urologically beneficial agents in pharmaceutically effective amounts. | 07-23-2009 |
| 20100268246 | ATRAUMATIC MEDICAL RETRIEVAL DEVICE - Baskets with atraumatic distal tips allow the capture of material from difficult-to-reach areas of the body, while reducing the risk of tissue damage. | 10-21-2010 |
| 20100280514 | METHOD OF MANUFACTURING RF ABLATION PROBE WITH UNIBODY ELECTRODE ELEMENT - An ablation probe and method of manufacturing the ablation probe are provided.

| 20110066158 | ATRAUMATIC MEDICAL DEVICE - A medical device, and related method, for manipulating material, such as calculi, within a patient's body includes a handle, a sheath, a retrieval basket, and a retainer coupled to the distal end of the retrieval basket. The retrieval basket includes a plurality of legs, each of which includes an intermediate portion located at the distal end of the retrieval basket. The retainer secures at least the intermediate portion of one of the plurality of legs to the intermediate portion of another of the plurality of legs. | 03-17-2011 |
| 20110066159 | MEDICAL RETRIEVAL DEVICE - A medical retrieval device, and related method, for removing material, such as calculi, from a patient's body. In one embodiment, the device includes a handle, a sheath, and a retrieval assembly located at the distal end of the retrieval device. The retrieval assembly includes a plurality of legs, each of which includes a lumen for receiving fluid. The legs are made of an expandable material that will allow the legs to inflate when the lumen receives a fluid. In another embodiment, the device includes a core element wound to form a helical coil. The helical coil has a lumen for receiving a fluid. The core element is made of an expandable material that allows it to inflate when the lumen within the helical coil receives a fluid. | 03-17-2011 |
| 20110143903 | RELEASABLE BASKET AND METHOD OF MAKING THEREOF - A medical retrieval device includes a basket formed of two or more loops. The basket may be used to retrieve material (e.g., a urinary stone) from a body. The basket opens and closes for end-encapsulation of a stone and is strengthened by support members that interconnect the basket loops. A captured stone may be released from the basket with the basket still in the body by opening the loops. | 06-16-2011 |
